Witam wszystkich po raz kolejny. Jako że odwiedził mnie listonosz z długo i niecierpliwie wyczekiwaną żółtą kopertą, to postaram się dzisiaj opisać Wam tutaj pokrótce gadżet, który to był w środku - moduł cyfrowego radia FM zrobiony na układzie TEA5767 firmy NXP. Moduł ten to …. powiedziałbym, że to kompletne radio, choć by wydobyć z niego dźwięk, potrzebne będzie kilka dodatkowych elementów. https://obrazki.elektroda.pl/4729291600_1522857906_thumb.jpg https://obrazki.elektroda.pl/1658815900_1522857924_thumb.jpg Wymiary tego modułu to 11x11x2mm – czyli dosłownie maleństwo, uważajcie, żeby go nie zgubić podczas zabawy z nim. :) Ceny za moduł zaczynają się od $0,72 wraz z przesyłką na Aliexpress, na Allegro trzeba zapałacie wraz z przesyłką ok. 12zł, choć można znaleźć i oferty kilkukrotnie droższe - nie wiem, czym różnią się one od tych tańszych. Ja swój „odbiornik” zakupiłem z Chin i nie było z nim żadnych problemów – „ruszył od pierwszego strzała”. Dzięki temu maleństwu możemy odbierać fale radiowe w stereo w zakresie od 87,5MHz do 108MHz. Napięcie zasilania to 2,5V do 5VDC. Pobór prądu po ustawieniu stacji radiowej to ok. 13mA przy zasilaniu modułu z 5V. Poniżej rysunek z wyprowadzeniami naszego układu. https://obrazki.elektroda.pl/4522088800_1522859033_thumb.jpg 1 – SDA 2 – SCL 3 – BUS MODE 4 – WRITE/WRITE 5 – VCC 6 – GND 7 – Wyjście audio kanał lewy 8 – Wyjście audio kanał lewy 9 – MPXO 10 – antena Moduł ten jest sterowany za pomocą komunikacji I2C, więc potrzebny nam będzie jakiś mikroprocesor, by ustawić nasza ulubiona stację. Ponadto wyjście audio jest na tyle słabe, że nie „uciągnie” nawet słuchawek, więc potrzebny będzie wzmacniacz. Ja użyłem małego taniego gotowego wzmacniacza w klasie D opartego o układ PAM8610 - napisałem małego, ale porównując go do modułu radia, to nie można powiedzieć, że jest mały. Potrzebować jeszcze będziemy dwóch rezystorów (ja użyłem 10k, można też dać 4,7k) do podciągnięcia linii komunikacyjnych SDA i SCL do plusa - w zasadzie to wszystko co potrzeba nie licząc źródła zasilania, kilku przewodów i jakiegoś głośniczka. Poniżej rysunek, jak to ma wyglądać. https://obrazki.elektroda.pl/9862667900_1522858061_thumb.jpg BUS MODE zwieramy do masy, by działała komunikacja poprzez I2C. Jako że moduł jest naprawdę mały, a jego raster nie jest standardowy tylko 2mm, więc trzeba było sobie jakoś poradzić, no i wyszła taka „hybryda” jak na zaprezentowanych zdjęciach poniżej. :) https://obrazki.elektroda.pl/9483666800_1522858773_thumb.jpg https://obrazki.elektroda.pl/5015279100_1522858774_thumb.jpg https://obrazki.elektroda.pl/9107461500_1522858774_thumb.jpg Chodzi tu o przetestowanie modułu, a nie o walory estetyczne, więc wybaczcie – zrobiłem to na McaGyver`a i ważne, że działa, następnym razem postaram się bardziej, by prócz uszy i oczy mogły się nacieszyć. ;) Do sterowania radyjka użyłem zestawu uruchomieniowego ZL2AVR, choć wystarczy tu płytka stykowa i jakiś mikroprocesor, który będzie wysyłał kilka bajtów za pomocą I2C – np. AVR czy PIC lub popularne Arduino. Ok, wiemy już jak podłączyć nasz moduł, więc przejdźmy do opisu, jak rozkazać radiu „grać” wybraną przez nas częstotliwość. Musimy wysłać do naszego radia 5 bajtów, a przed tym wysłać jeszcze adres naszego odbiornika radiowego. Oczywiście z pomocą przychodzi dokumentacja. Adres naszego radia wedle dokumentacji to: 110 000b Moduł może działać w dwóch różnych trybach pracy – zapisu i odczytu, co należy podać w adresie. 0 - tryb zapisu 1 - tryb odczytu Stąd też będziemy używać adresu &B1100 0000 (w zapisie dwójkowym lub &HC0 w zapisie szesnastkowym), gdyż wybieramy tryb zapisu. Fragment dokumentacji dla opisu adresu: https://obrazki.elektroda.pl/1608968500_1522858166_thumb.jpg Dalej należy wysłać 5 bajtów, których opis znajdziemy w dokumentacji. W pierwszych dwóch bajtach podajemy częstotliwość naszej radiostacji - PLL, jest to 14 bitów. Fragment dokumentacji dla opisu pierwszych dwóch bajtów dla pracy w trybie zapisu: https://obrazki.elektroda.pl/7660629200_1522858181_thumb.jpg https://obrazki.elektroda.pl/5917543000_1522858193_thumb.jpg PLL możemy wyliczyć ze wzoru: https://obrazki.elektroda.pl/1533741300_1522859463_thumb.jpg gdzie RMF to częstotliwość naszej stacji w MHz. Weźcie pod uwagę że w mianowniku mamy częstotliwość kwarcu, który jest w tym module. Przy użyciu samego układu TEA5767 można zastosować tam inny kwarc, ale trzeba jego wartość wziąć pod uwagę w tym wzorze oraz wziąć go pod uwagę w ustawieniach dla bajtu czwartego i piątego - chodzi o bity XTAL w bajcie czwartym oraz PLLREF w bajcie piątym. Np. dla częstotliwości stacji 98MHz i kwarcu 32,768kHz, który jest zastosowany w tym module ze wzoru wyjdzie nam 11990,3564453125, z czego jako PLL przyjmujemy część całkowitą tej liczby czyli PLL=11990, co daje nam w zapisie binarnym 10111011010110. Bajt pierwszy w tym przypadku to: MUTE SM PLL13-PLL8, gdzie bit MUTE ustawiamy na 0 a bit SM też na 0, co daje nam kompletny bajt w formie &B00101110. Drugi bajt to PLL7-PLL0, czyli &B11010110 Kolejne bajty to ustawienia, których nie będę tutaj opisywał – mamy je opisane w dokumentacji. Fragment dokumentacji dla opisu kolejnych trzech bajtów dla pracy w trybie zapisu: https://obrazki.elektroda.pl/4333756100_1522858230_thumb.jpg https://obrazki.elektroda.pl/8368817700_1522858238_thumb.jpg https://obrazki.elektroda.pl/6784757900_1522858249_thumb.jpg Ja wysyłam tutaj &B00010000 jako bajt 3 &B00010000 jako bajt 4 &B00000000 jako bit 5 Czyli by wydobyć dźwięk naszej wybranej stacji radiowej (przykład 98MHz), wysyłamy kolejno: &B11000000 lub &HC0 – zapis dwójkowy lub szesnastkowy &B00101110 lub &H2E &B11010110 lub &HD6 &B00010000 lub &H10 &B00010000 lub &H10 &B00000000 lub &H0 Na początku mojej zabawy wysyłałem do modułu te dane co 100ms - proponuję tego nie robić, gdyż wprowadza to pewne zakłócenia w pracy radia. Powoduje to przerwanie dźwięku na ułamek sekundy - tak jakby na pilocie od TV co chwilę naciskać guzik od wyboru tego samego kanału. Poniżej kod napisany w Basomie dla ATmega8 do obsługi tego radia. Zajmuje on ok. 25% pamięci, po zrezygnowaniu z wyliczania przez program bajtów, a wpisaniu ich na stałe możemy zejść do 6% pamięci, ale nie wiem, czy uda się to odpalić na ATtiny13 z powodu braku sprzętowego I2C. $regfile = "m8def.dat" $crystal = 8000000 Dim S As String * 6 Config Scl = Portc.1 Config Sda = Portc.0 Config I2cdelay = 10 Dim Pll As Single Dim Fset As Word Dim Dane As Byte Config Pind.0 = Input Config Pind.1 = Input Config Pind.2 = Input S1 Alias Pind.0 S2 Alias Pind.1 S3 Alias Pind.3 Set Portd.0 Set Portd.1 Set Portd.3 Do Debounce S1 , 0 , Stacja_1 , Sub Debounce S2 , 0 , Stacja_2 , Sub Debounce S3 , 0 , Stacja_3 , Sub Loop Stacja_1: Pll = 99.1 I2cinit I2cstart I2cwbyte &HC0 'adres Pll = Pll * 1000000 Pll = Pll + 225000 Pll = Pll * 4 Pll = Pll / 32768 'Pll=12124,6337890625 dla 99,1MHz Fset = Int(pll) 'Fset=Int(pll) przypisuje część całkowitą Pll do Fset czyli Fset=12124, binarnie=10111101011100 Dane = High(fset) 'przypisanie zmiennej DANE wartości starszego bajtu zmiennej Fset czyli 101111 Reset Dane.7 'jako że starszy bajt wygląda tak 101111 Reset Dane.6 'utawienie bitów 7 i 6 na 0 czyli 00101111 I2cwbyte Dane 'wysłanie starszego bajtu zmiennej Dane ->00101111 Dane = Low(fset) 'Przypisanie zmiennej Dane wartości młodszego bajtu Fset czyli 01011100 I2cwbyte Dane 'wysłanie młodszego bajtu zmiennej Dane ->01011100 I2cwbyte &B00010000 'bajt 3 I2cwbyte &B00010000 'bajt 4 I2cwbyte &B00000000 'bajt 5 I2cstop Return Stacja_2: Pll = 103.3 I2cinit I2cstart I2cwbyte &HC0 Pll = Pll * 1000000 Pll = Pll + 225000 Pll = Pll * 4 Pll = Pll / 32768 Fset = Int(pll) Dane = High(fset) Reset Dane.7 Reset Dane.6 I2cwbyte Dane Dane = Low(fset) I2cwbyte Dane I2cwbyte &B00010000 I2cwbyte &B00010000 I2cwbyte &B00000000 I2cstop Return Stacja_3: Pll = 104.5 I2cinit I2cstart I2cwbyte &HC0 Pll = Pll * 1000000 Pll = Pll + 225000 Pll = Pll * 4 Pll = Pll / 32768 Fset = Int(pll) Dane = High(fset) Reset Dane.7 Reset Dane.6 I2cwbyte Dane Dane = Low(fset) I2cwbyte Dane I2cwbyte &B00010000 I2cwbyte &B00010000 I2cwbyte &B00000000 I2cstop Return Dla mniej wtajemniczonych wyjaśnię może, skąd się wzięła w kodzie poniższa część, bo pisałem o wysłaniu adresu i pięciu bajtów, a widać, że wysyłam tylko adres i trzy bajty. Fset = Int(pll) Dane = High(fset) Reset Dane.7 Reset Dane.6 I2cwbyte Dane Dane = Low(fset) I2cwbyte Dane Jako że ustawienia dla każdej stacji w trzech ostatnich bajtach są identyczne, więc te bajty wpisane w program są na stałe. Pierwsze dwa zmieniają się w zależności od wybranej częstotliwości i żeby tego nie robić samemu - żeby uprościć sobie, to program jest tak napisany, że wystarczy mu wpisać wybraną częstotliwość w zmienną PLL, a ten sam sobie wyliczy pierwsze dwa bajty do wysłania. Chcąc wpisać swoje częstotliwości do programu, wpisujemy częstotliwość w MHz w zmienną PLL, a program sam wyliczy sobie dwa pierwsze bajty. Przy uruchomieniu tego małego radyjka obyło się bez kłopotów – z głośnika wydobył się dźwięk zaraz po wgraniu programu do procesora i naciśnięciu guzika. Największym problemem w tym wszystkim było tylko polutowanie tej „hybrydy”, ale myślę, że nie będzie to problemem, by z użyciem Google znaleźć bibliotekę np. w Eaglu pod to maleństwo. Jak widać ze zdjęć - użyłem jako anteny kawałka drutu długości ok. 10cm i jak można usłyszeć na załączonych nagraniach - radio gra dość dobrze Radio posiada funkcję automatycznego szukania stacji z możliwością ustawienia jej czułości - 3 stopnie czułości. Nie miałem zbytnio czasu, by ją dokładnie przetestować. Myślę, że pomocny byłby tutaj odczyt aktualnej częstotliwości z radia, gdyż podczas automatycznego szukania radio zatrzymywało się na czymś, co uważało za stację radiową, a ja nie byłem w stanie uzyskać informacji, jaka to częstotliwość, przez co błądziłem po omacku w gąszczu rożnego rodzaju szumów i ciszy, gdzie czasem udało się natrafić na stacje, ale nie zająć jej częstotliwości. Być może ktoś podzieli się tutaj wiedzą na temat odczytu informacji z tego modułu - mi nie udało się uzyskać żadnych informacji z modułu w trybie odczytu, być może robię to niepoprawnie. W załącznikach dokumentacja do opisywanego modułu radia oraz dwa nagrania dźwięku, jaki to wytwarza to radyjko by można było samemu ocenić czy można się spodziewać czegoś miłego po module za niespełna dolara, czy raczej można się tylko rozczarować, jak to zazwyczaj bywa w przypadku chińskich gadżetów. Mam nadzieję, że ten opis zachęci Was do zabawy z tym modułem radia i opisywaniu tutaj swoich zmagań z nim i osiągnięć, co pozwoli rozwinąć ten temat i pomóc innym przy poznawaniu tego maleństwa.

7.4 Crystal oscillator
The crystal oscillator can operate with a 32.768 kHz clock crystal or a 13 MHz crystal. The
temperature drift of standard 32.768 kHz clock crystals limits the operational temperature
range from −10 °C to +60 °C.
The PLL synthesizer can be clocked externally with a 32.768 kHz, a 6.5 MHz or a 13 MHz
signal via pin XTAL2.
The crystal oscillator generates the reference frequency for:
•
•
•
•
The reference frequency divider for the synthesizer PLL
The timing for the IF counter
The free-running frequency adjustment of the stereo decoder VCO
The center frequency adjustment of the IF filters
7.5 PLL tuning system
The PLL synthesizer tuning system is suitable to operate with a 32.768 kHz or a 13 MHz
reference frequency generated by the crystal oscillator or applied to the IC from an
external source. The synthesizer can also be clocked via pin XTAL2 at 6.5 MHz. The PLL
tuning system can perform an autonomous search tuning function.
7.6 RF AGC
The RF AGC prevents overloading and limits the amount of intermodulation products
created by strong adjacent channels.
7.7 IF filter
Fully integrated IF filter.
7.8 FM demodulator
The FM quadrature demodulator has an integrated resonator to perform the phase shift of
the IF signal.
7.9 Level voltage generator and analog-to-digital converter
The FM IF analog level voltage is converted to 4 bits digital data and output via the bus.
7.10 IF counter
The IF counter outputs a 7-bit count result via the bus.
7.11 Soft mute
The low-pass filtered level voltage drives the soft mute attenuator at low RF input levels.
The soft mute function can be switched off via the bus.
7.12 MPX decoder
The PLL stereo decoder is adjustment-free. The stereo decoder can be switched to mono
via the bus.

7.13 Signal dependent mono to stereo blend
With a decreasing RF input level the MPX decoder blends from stereo to mono to limit the
output noise. The continuous mono to stereo blend can also be programmed via the bus
to an RF level depending switched mono to stereo transition. Stereo Noise Cancelling
(SNC) can be switched off via the bus.
7.14 Signal dependent AF response
The audio bandwidth will be reduced with a decreasing RF input level. This function can
be switched off via the bus.
7.15 Software programmable ports
Two software programmable ports (open-collector) can be addressed via the bus.
The port 1 (pin SWPORT1) function can be changed with write data byte 4 bit 0
(see Table 13). Pin SWPORT1 is then output for the ready flag of read byte 1.
7.16 I2C-bus and 3-wire bus
The 3-wire bus and the I2C-bus operate with a maximum clock frequency of 400 kHz.
Before any READ or WRITE operation the pin BUSENABLE has to be HIGH for at
least 10 µs.
The I2C-bus mode is selected when pin BUSMODE is LOW, when pin BUSMODE is HIGH
the 3-wire bus mode is selected.

8. I2C-bus, 3-wire bus and bus-controlled functions
8.1 I2C-bus specification
Information about the I2C-bus can be found in the brochure “The I2C-bus and how to use
it” (order number 9398 393 40011).
The standard I2C-bus specification is expanded by the following definitions:
IC address: 110 0000b
Structure of the I2C-bus logic: slave transceiver
Subaddresses are not used
The maximum LOW-level input and the minimum HIGH-level input are specified to
0.2VCCD and 0.45VCCD respectively.
The pin BUSMODE must be connected to ground to operate the IC with the I2C-bus.
Remark: The I2C-bus operates at a maximum clock frequency of 400 kHz. It is not
allowed to connect the IC to an I2C-bus operating at a higher clock rate.
8.1.1 Data transfer
Data sequence: address, byte 1, byte 2, byte 3, byte 4 and byte 5 (the data transfer has to
be in this order). The Least Significant Bit (LSB) = 0 of the address indicates a WRITE
operation to the TEA5767HN.
Bit 7 of each byte is considered as the Most Significant Bit (MSB) and has to be
transferred as the first bit of the byte.
The data becomes valid bitwise at the appropriate falling edge of the clock. A STOP
condition after any byte can shorten transmission times.
When writing to the transceiver by using the STOP condition before completion of the
whole transfer:
• The remaining bytes will contain the old information
• If the transfer of a byte is not completed, the new bits will be used, but a new tuning
cycle will not be started
The IC can be switched into a low current Standby mode with the standby bit; the bus is
then still active. The standby current can be reduced by deactivating the bus interface
(pin BUSENABLE LOW). If the bus interface is deactivated (pin BUSENABLE LOW)
without the Standby mode being programmed, the IC maintains normal operation, but is
isolated from the bus lines.
The software programmable output (SWPORT1) can be programmed to operate as a
tuning indicator output. As long as the IC has not completed a tuning action,
pin SWPORT1 remains LOW. The pin becomes HIGH, when a preset or search tuning is
completed or when a band limit is reached.
The reference frequency divider of the synthesizer PLL is changed when the MSB in
byte 5 is set to logic 1. The tuning system can then be clocked via pin XTAL2 at 6.5 MHz.

respectively.
Fig 6. I2C-bus timing diagram
8.3 3-wire bus specification
The 3-wire bus controls the write/read, clock and data lines and operates at a maximum
clock frequency of 400 kHz.
Hint: By using the standby bit the IC can be switched into a low current Standby mode. In
Standby mode the IC must be in the WRITE mode. When the IC is switched to READ
mode, during standby, the IC will hold the data line down. The standby current can be
reduced by deactivating the bus interface (pin BUSENABLE LOW). If the bus interface is
deactivated (pin BUSENABLE LOW) without the Standby mode being programmed, the
IC maintains normal operation, but is isolated from the clock and data line.
8.3.1 Data transfer
Data sequence: byte 1, byte 2, byte 3, byte 4 and byte 5 (the data transfer has to be in this
order).

Low-power FM stereo radio for handheld applications
A positive edge at pin WRITE/READ enables the data transfer into the IC. The data has to
be stable at the positive edge of the clock. Data may change while the clock is LOW and is
written into the IC on the positive edge of the clock. Data transfer can be stopped after the
transmission of new tuning information with the first two bytes or after each following byte.
A negative edge at pin WRITE/READ enables the data transfer from the IC. The
WRITE/READ pin changes while the clock is LOW. With the negative edge at
pin WRITE/READ the MSB of the first byte occurs at pin DATA.
The bits are shifted on the negative clock edge to pin DATA and can be read on the
positive edge.
To do two consecutive read or write actions, pin WRITE/READ has to be toggled for at
least one clock period. When a search tuning request is sent, the IC autonomously starts
searching the FM band; the search direction and search stop level can be selected. When
a station with a field strength equal to or greater than the stop level is found, the tuning
system stops and the ready flag bit is set to HIGH. When, during search, a band limit is
reached, the tuning system stops at the band limit and the band limit flag bit is set to
HIGH. The ready flag is also set to HIGH in this case.
The software programmable output (SWPORT1) can be programmed to operate as a
tuning indicator output. As long as the IC has not completed a tuning action,
pin SWPORT1 remains LOW. The pin becomes HIGH, when a preset or search tuning is
completed or when a band limit is reached.
The reference frequency divider of the synthesizer PLL is changed when the MSB in
byte 5 is set to logic 1. The tuning system can then be clocked via pin XTAL2 at 6.5 MHz.
8.3.2 Power-on reset
At Power-on reset the mute is set, all other bits are random. To initialize the IC all bytes
have to be transferred.

Calculation of this 14-bit word can be done as follows:
formula for high side injection:
4 × ( f RF + f IF )
4 × ( f RF – f IF )
N = -------------------------------------- ; formula for low side injection: N = -------------------------------------f ref
f ref
where:
N = decimal value of PLL word;
fRF = the wanted tuning frequency [Hz];
fIF = the intermediate frequency [Hz] = 225 kHz;
fref = the reference frequency [Hz] = 32.768 kHz for the 32.768 kHz crystal; fref = 50 kHz for the 13 MHz crystal or when externally
clocked with 6.5 MHz.
6
Example for receiving a channel at 100 MHz with high side injection:
3
4 × ( 100 × 10 + 225 × 10 )
N = ------------------------------------------------------------------- = 12234
32768
The PLL word becomes 2FCAh.
[2]
VRF in Figure 13 is replaced by VRF1 + VRF2. The radio is tuned to 98 MHz (high side injection).
[3]
Low side and high side selectivity can be switched by changing the mixer from high side to low side LO injection.

18. Soldering
This text provides a very brief insight into a complex technology. A more in-depth account
of soldering ICs can be found in Application Note AN10365 “Surface mount reflow
soldering description”.
18.1 Introduction to soldering
Soldering is one of the most common methods through which packages are attached to
Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides both
the mechanical and the electrical connection. There is no single soldering method that is
ideal for all IC packages. Wave soldering is often preferred when through-hole and
Surface Mount Devices (SMDs) are mixed on one printed wiring board; however, it is not
suitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and high
densities that come with increased miniaturization.
18.2 Wave and reflow soldering
Wave soldering is a joining technology in which the joints are made by solder coming from
a standing wave of liquid solder. The wave soldering process is suitable for the following:
• Through-hole components
• Leaded or leadless SMDs, which are glued to the surface of the printed circuit board
Not all SMDs can be wave soldered. Packages with solder balls, and some leadless
packages which have solder lands underneath the body, cannot be wave soldered. Also,
leaded SMDs with leads having a pitch smaller than ~0.6 mm cannot be wave soldered,
due to an increased probability of bridging.
The reflow soldering process involves applying solder paste to a board, followed by
component placement and exposure to a temperature profile. Leaded packages,
packages with solder balls, and leadless packages are all reflow solderable.
Key characteristics in both wave and reflow soldering are:
•
•
•
•
•
•
Board specifications, including the board finish, solder masks and vias
Package footprints, including solder thieves and orientation
The moisture sensitivity level of the packages
Package placement
Inspection and repair
Lead-free soldering versus PbSn soldering
18.3 Wave soldering
Key characteristics in wave soldering are:
• Process issues, such as application of adhesive and flux, clinching of leads, board
transport, the solder wave parameters, and the time during which components are
exposed to the wave
• Solder bath specifications, including temperature and impurities

18.4 Reflow soldering
Key characteristics in reflow soldering are:
• Lead-free versus SnPb soldering; note that a lead-free reflow process usually leads to
higher minimum peak temperatures (see Figure 15) than a PbSn process, thus
reducing the process window
• Solder paste printing issues including smearing, release, and adjusting the process
window for a mix of large and small components on one board
• Reflow temperature profile; this profile includes preheat, reflow (in which the board is
heated to the peak temperature) and cooling down. It is imperative that the peak
temperature is high enough for the solder to make reliable solder joints (a solder paste
characteristic). In addition, the peak temperature must be low enough that the
packages and/or boards are not damaged. The peak temperature of the package
depends on package thickness and volume and is classified in accordance with
Table 35 and 36
Table 35.

Moisture sensitivity precautions, as indicated on the packing, must be respected at all
times.
Studies have shown that small packages reach higher temperatures during reflow
soldering, see Figure 15.
