Changing the DSI_TE pin in the STM32F469 (tearing effect)

Hello everyone,

I am using the STM32F469i-disco for my touch screen project and I was able to modify the sample example in the STM32Cube_FW_F4_V1 to satisfy my project. ( ..\STM32Cube_FW_F4_V1\Projects\STM32469I-Discovery\Examples\BSP) Now I am trying to use the STM32F469BIT6 (TQFP176 ) instead of the BGA one used in the Discovery board.

My problem is I do not find a way to change the DSI_TE pin in the Library from PJ2. I looked everywhere in the code but I do not find it. 

Thank you for your help

Hi

eleuche.Mohamed

, what is the tearing effect you mentioned in the question? (I'm having a similar issue on the same board, maybe they might be related..)

The tearing effect is an effect similar to judder.

It is the pin 22 of the LCD module connector CN10 (TE), since the 

STM32F469BIT6 (TQFP176 ) does not have PJ2, I need to move it to another port and I need to change the pin in the software!
