Czy układ będzie dział z wyświetlaczem DEM 128064A Taki mam Wiem że ma inne wyprowadzenia podłączyłem zgodnie z aplikacją i nie działa. Załącznik Aplikacja tego wyświetlacza. Tabelka z wyprowadzeniami na stronie 5. Udało się uruchomić ale nie wyświetla tak jak powinno być http://obrazki.elektroda.pl/2484705100_1328530643_thumb.jpg Kolejne uruchomienia http://obrazki.elektroda.pl/7990087400_1328531199_thumb.jpg Co jest tego przyczyną ? Co połączyłem nie tak ? Może coś innego jest nie tak ?

11. OPERATING PRINCIPLES & METHODS
11-1. I/O Buffer
Input buffer controls the status between the enable the and disable of chip. Unless the CS1 to CS2 is in active mode. Input
or output of data and instruction does not execute. Therefore internal stade is not change.
Bust RSTB and ADC can operate regardless CS1-CS2.
11-2. Input register
Input register is provided to interface with MPU which is different operating frequency. Input register stores the data
temporarily before writing it into display RAM. When CS1 to CS2 are in the active mode, R/W and RS select the input
register. The data from MPU is written into input register. Then Writing it into display RAM. Data latched for the E signal
and write automatically into the display data RAM by internal operation.
11-3. Output register
Output register stores the data temporarily from display data RAM when CS1 and CS2 are in active mode and R/W and
RS=H, stored data in display data RAM is latched in output register. When CS1 to CS2 are in the active mode and R/W=H,
RS=L, status data (busy check) can read out. To read the contents of display data RAM, twice access of read instruction
needed. In first access, data in display data RAM is latched into output register. In second access, MPU can read data which
is latched. That is , to read the data in display data RAM, it needs dummy read. But staus read is not read needed dummy.

11-4. Reset
The system can be initialized by setting RSTB terminal at low level when turning power on receiving instruction from
RAM. When RSTB becomes low, following procedure is occurred.
1. Display off
2. Display start line register become set by 0. (Z-address 0)
While RSTB is low, No instruction except status read can be accepted. Therefore, execute other instructions after making
sure than DB4=0 (clear RSTB) and DB7=0 (ready) by status read instruction.
The conditions of power supply data initial power up are shown in table 1.

Busy flay indicates that S6B0108 is operating or on operating. When busy flag is high, S6B0108 is internal operating.
When busy flag is low, S6B0108 can accept the data or instruction.

11-6. Display ON/OFF Flip-Flop
The display on/off flip-flop makes on/off the liquid crystal display. When flip-flop is reset (logical low).
selective voltage or non selective voltage appears on segment output terminals. When flip-flop is set
(logic high), non selective voltage appears on segment output terminals regardless of display RAM data. The display on/off
flip-flop can changes status by instruction. The display data at all segment disappear while RSTB is low. The status of the
flip-flop is output to DB5 by status read instruction.
11-7. X Page Register
X page register designates pages of the internal display data RAM.
Count function is not available. An adders is set by instruction.

11-8. Y address counter
Y address counter designates address of the internal data RAM. An address is set by instruction and is increased by 1
automatically by read or write operations of display data.
11-9. Display Data RAM
Display Data RAM stores a display data for liquid crystal display. To indicate on state dot matrix of liquid crystal display,
write data 1. The other way , off state, writes 0.
11-10. Display Start Line Register
The display start line register indicates of display data RAM to display top liquid crystal display. Bit data
(DB & lt; 0:5 & gt; ) of the display start line set instruction is latched in display start line register. Latched data is transferred to the Z
address counter while FRM is high, presetting the Z address counter. It is used for scrolling of the liquid crystal display
screen.
12. DISPLAY CONTROL INSTRUCTION
The display control instructions the internal state of the S6B0108. Instruction is received from MPU to S6B0108 for the
display control. The following table shows various instructions.

13. LCD MODULES HANDLING PRECAUTIONS
Please remove the protection foil of polarizer before using.
The display panel is made of glass. Do not subject it to a mechanical shock by dropping it from a high place, etc.
If the display panel is damaged and the liquid crystal substance inside it leaks out, do not get any in your mouth. If the
substance come into contact with your skin or clothes promptly wash it off using soap and water.
Do not apply excessive force to the display surface or the adjoining areas since this may cause the color tone to vary.
The polarizer covering the display surface of the LCD module is soft and easily scratched. Handle this polarize
carefully.
To prevent destruction of the elements by static electricity, be careful to maintain an optimum work environment.
-Be sure to ground the body when handling the LCD module.
-Tools required for assembly, such as soldering irons, must be properly grounded.
-To reduce the amount of static electricity generated, do not conduct assembly and other work under dry conditions.
-The LCD module is coated with a film to protect the display surface. Exercise care when peeling off this protective
film since static electricity may be generated.
Storage precautions
When storing the LCD modules, avoid exposure to direct sunlight or to the light of fluorescent lamps. Keep the
modules in bags designed to prevent static electricity charging under low temperature / normal humidity conditions
(avoid high temperature / high humidity and low temperatures below 0°C). Whenever possible, the LCD modules
should be stored in the same conditions in which they were shipped from our company.
14. OTHERS
Liquid crystals solidify at low temperature (below the storage temperature range) leading to defective orientation of
liquid crystal or the generation of air bubbles (black or white). Air bubbles may also be generated if the module is
subjected to a strong shock at a low temperature.
If the LCD modules have been operating for a long time showing the same display patterns may remain on the screen
as ghost images and a slight contrast irregularity may also appear. Abnormal operating status can be resumed to be
normal condition by suspending use for some time. It should be noted that this phenomena does not adversely affect
performance reliability.
To minimize the performance degradation of the LCD modules resulting from caused by static electricity, etc.
exercise care to avoid holding the following sections when handling the modules:
- Exposed area of the printed circuit board
- Terminal electrode sections
