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:

And this is the code:
[code]//RS pin connect FSMC_A10 while the data address is

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