Проблема в следующем: При чтении FSMC значения всегда возвращается предыдущее записанное в FSMC значение.
А нужно значения цвета пикселя SSD1963...
Собственно, в чем прикол???
Считывал так
Код: Выделить всё
#define LCD_REG (*((volatile unsigned short *) 0x60000000))
#define LCD_RAM (*((volatile unsigned short *) 0x60020000))
//0x2E read_memory_start
LCD_Write_Com(0x2E);
rtk[0]=LCD_RAM; //Все значения rtk[] одни и те же, то есть, что было записано в прошлый раз (LCD_Write_Com(0x2E))
rtk[1]=LCD_RAM;
rtk[2]=LCD_RAM;
rtk[3]=LCD_RAM;
