I am involving in an electronic project--make a set of control board. The MCU is 103ZET6 while the driving chip is SSD1963 and the screen is AT070TN92. However,I don’t know why the screen can’t be lighted?
IF you need more detail or datasheet about SSD1963,please click: http://www.kynix.com/Detail/189630/SSD1963G41.html
And this is the code:
[code]//RS pin connect FSMC_A10 while the data address is (2^10)*2 | 0x60000000  =  0x6000 0800

#define Bank1_LCD_Data    ((uint32_t)0x60000800)    //disp Data ADDR
#define Bank1_LCD_Reg            ((uint32_t)0x60000000)                 //disp Reg  ADDR
