This is primarily a user forum, there's apparently no one here to perform your task/request at this time.

Thank you sir for reply but  apparently you haven't even read the post

I am not asking for a design support!! , I am asking for a documentation to how an add a touch driver to a ST product which is STEMWIN .Is that a wrong question to ask on the user forum !??

Hello,

Plz I need help from ST engineers or somebody who have done this before  , I am using an LCD with ADS7846 touch driver  and STM32F4 discovery  and I am struggling for a whole day to port it to STEMWIN. (The LCD worked fine but the touch doesn't work at all)

I have edited many functions in ''stm324xg_eval_ioe.c'' which relates to the touch screen configuration and added the code for ADS7846 from another library But this still doesn't work .

I need help please

Thank in advance

''Look, you can ask any questions you want, just don't expect anyone to rush around and service you. I'm not the one bitching about my post going unanswered.You might do better looking at the Segger forum and examples, or frankly asking your display vendor for support.

Ignoring the STEMWIN for a moment, in your 2-3 days with the porting have you proven that the hardware is functioning correctly and that you can actually communicate with the ADS chip? Do the readings from the chip seem to be valid?

Can you see signalling via a scope or logic analyzer? Does the display use the ADS chip with an IO Expander?

Hello , Thank you .

The touch driver works fine with another library.I just need someone who is responsible for STEMWIN to give me any sort of documentation to add a touch driver
