Numeric keypad with STM32F429I-Disco guidance
Attached is the Demo file that I did get to work and If I remeber correctly, it had some button functions in it too.
But, They didn’t do anything except blink when you touched them I beleive that it was only meant for as a demo or is an unfinished project or part of a project were I may have faile to include some of the other files and left them out of it.
Maybe there is something in that code to help you.
jer 
P.S. darn the file is to big for this forrum at 3.7MB.
If you like I can get the file to you via Email or my Copy Account, just send me a PM if you would like it, Meanwhil I will try to find the link as to where I had found it.
Your in luck!!
I found it as it was on Github !!
