Hi

I'm trying to use STM32F429 to drive TFT LCD and want to use it without any driver chip directly by the micro pins. As I checked, some pins are missing in 100pin package such as LCD_R0, LCD_G1, LCD_G2, LCD_B0, LCD_B7 pins.

Does it mean that I have to use 144 pin package or still there is some way on 100pin ?

Thank you

Behnam

Hi Beh,

In LQFP100 package, the mode 18bpp is supported for LCD. That is why LCD_R0 isn't available.

The other mentioned pins are there: 

- LCD_G1: 5

- LCD_G2: 31

- LCD_B0: 3

- LCD_B7: 96

You have to refer to the product
