Witam wszystkich, Chciałbym obsłużyć wyświetlacz RG160160a (celem ostatecznym jest zbudowanie analizatora widma akustycznego). Jest on obsługiwany przez wspomniany wcześniej kontroler (4 sztuki są na PCB). Problem, z którym nie mogę sobie poradzić polega na tym, że nie mogę stworzyć wierszy, które by się różniły między sobą układem kropek. Kiedy przychodzi nowy wiersz wszystkie pozostałe przyjmują taki sam układ zapalonych/zgaszonych punktów tak, że cokolwiek bym nie robił otrzymuję pionowe paski. Poniżej zamieszczam kod mojego programu, a zdjęcie to efekt jego wykonania. Jak widać na zdjęciu jest kiepski kontrast między zapalonymi, a zgaszonymi punktami - czy to jest dlatego, że mam jedno źródło zasilania +5V, a nie jak wg noty katalogowej (z tego, co zrozumiałem do zasilania LCD powinienem podać -16 do - 18V)? Pewnie pominąłem coś bardzo oczywistego w tym wszystkim i bardzo proszę pomoc w tym temacie. #define F_CPU 8000000L #include <avr/io.h> #include <util/delay.h> const int krok= 5000; void dane(short dana){ short bufor = PORTA; dana&=0b00001111; bufor&=0b11110000; bufor|=dana; PORTA=bufor; _delay_us(krok); PORTA^=0b00010000; _delay_us(krok); //PORTA^=0b10000000; PORTA^=0b00010000; _delay_us(krok); } void nowa_linia(){ //PORTA&=0b11011111; PORTA^=0b11000000; _delay_us(krok); PORTA^=0b00100000; //_delay_ms(krok); PORTA^=0b00100000; PORTA^=0b01000000; PORTA^=0b10000000; // _delay_us(1); //PORTA|=0b00101111; } int main(void) { DDRA = 0b11111111; PORTA=0b00001111; _delay_ms(10); for (int i=0; i<100; i++){ for (int j=0; j<20; j++){ dane(j); dane(i); } nowa_linia(); } while (1) { PORTA=0xff; } } Użyte piny: PA0-PA3 - D0 - D3; PA4 - CL2; PA5 - CL1; PA6 - FLM; PA7 - M. Tak duży delay wstawiłem tylko po to, żebym mógł dobrze obserwować zmiany na wyświetlaczu. Pozdrawiam

1. Avoid applying excessive shocks to the module or making any alterations or modifications
to it.
2. Don’t make extra holes on the printed circuit board, modify its shape or change the
components of LCD module.
3. Don’t disassemble the LCM.
4. Don’t operate it above the absolute maximum rating.
5. Don’t drop, bend or twist LCM.
6. Soldering: only to the I/O terminals.
7. Storage: please storage in anti-static electricity container and clean environment.
