Touch Interrupt Problem

[Charlie CHEN]

Hi professors,

I am using STM32H743 with my development board,and I am trying to build a Interrupt for the touch function,codes are down below.

By the way, the code is generated by TouchGFX and Board STM32H743I_EVAL.

Pin defined

Interrupt function in C++ file

This is the detecting pin function

Last is my test interrupt is break in or not.

I tried a lot but it didn`t work.

Is there any one can help?

Thank you!

Check if you have an Interrupt signal on the pin?

[Charlie CHEN]

Thanks for your reply,but I have no Oscilloscope beside, is there any method can figure it out?

[Slh]

Maybe with a LED and Resistor can you see the signal.

[Charlie CHEN]

Yes,but it did not work.

Or is there any suggestion?

Hi @Martin KJELDSEN​ ,

Thanks for your reply!

Yes,I am trying to build it with interrupt function,but I face the problem is that in Debug Mode didn`t detect where I touch then run into my Interrupt function.

Is it make the wrong way about build the function?

I have search many method,but was`t solved.

Hope you can help me!

Appreciate that !
