Przepraszam za późną odpowiedź ale przez ostatnie dni musiałem zająć się innymi sprawami. A więc tak. Wyświetlacz jest sprawny w 100% (wysłanie 16 bit sprawdzony na ARM z przykładowego kodu) także podanie 5v nie spowodowało uszkodzenia LCD. Od tego trzeba zacząć gdyż już zaczynałem wątpić w to czy pomimo napisania dobrego kodu wyświetlacz zadziała. Na schematach podobnych wyświetlaczy PIN_11 zarezerwowany jest dla bitu IM0 sterującego wyborem trybu 8/16bit. Na schemacie mojego wyświetlacza (kilka postów wyżej) widać, że PIN_11 jest oznaczony jako NC. Jednakże tak jak w schematach podobnych pcb do PIN_11 mimo, że oznaczonego jako NC doprowadzono masę lub + do wyboru rezystorami R4, R6. Na fizycznym pcb w miejscach R4 i R6 jest przerwa co by potwierdzało, że PIN_11 jest nieużywany jednakże po co w takim razie te rezystory? Ustawiono na sztywno 16 bit? Na to wynika. Bez sensu moim zdaniem no ale cóż. Skoro doszliśmy do tego, że 16 bit jest ustawiony na sztywno i muszę wysyłać dane wg wykresu czasowego dla 16 bit i WR ustawiać w stan niski przed podaniem danych na magistralę to dlaczego w kolejnej bibliotece (w załączniku) WR ustawiany jest w stan niski przed wystawieniem danej na szynie? CS również jest podnoszony po wysłaniu indexu... Co prawda jest to sterowanie 8bit ale z czasówki 8bit wynika to samo co czasówki 16bit. http://obrazki.elektroda.pl/8369531000_1322404642.gif A kod wygląda tak: void TSLCDOutDat(unsigned short dat) //write data to LCD { Clrb(LCD_LE_PRTC,LCD_LE_PIN); //clear LE LCD_DB_DPRT = dat >> 8; Setb(LCD_LE_PRTS,LCD_LE_PIN); //set LE Delay1us(1); Clrb(LCD_LE_PRTC,LCD_LE_PIN); //clear LE Clrb(LCD_CS_PRTC,LCD_CS_PIN); // clear CS Setb(LCD_RS_PRTS,LCD_RS_PIN); // set RS Setb(LCD_RD_PRTS,LCD_RD_PIN); // set RD LCD_DB_DPRT = dat; Clrb(LCD_WR_PRTC,LCD_WR_PIN); // clear WR Setb(LCD_WR_PRTS,LCD_WR_PIN); // set WR Setb(LCD_CS_PRTS,LCD_CS_PIN); // set CS } void ili9320_WriteIndex(unsigned char index) { Clrb(LCD_LE_PRTC,LCD_LE_PIN); //clear LE LCD_DB_DPRT = index >> 8; Setb(LCD_LE_PRTS,LCD_LE_PIN); //set LE Delay1us(1); Clrb(LCD_LE_PRTC,LCD_LE_PIN); Clrb(LCD_CS_PRTC,LCD_CS_PIN); // clear CS Setb(LCD_RS_PRTS,LCD_RS_PIN); // set RS Setb(LCD_RD_PRTS,LCD_RD_PIN); // set RD LCD_DB_DPRT = index; Clrb(LCD_WR_PRTC,LCD_WR_PIN); // clear WR Setb(LCD_WR_PRTS,LCD_WR_PIN); // set WR }
