Numeric keypad with STM32F429I-Disco guidance
Hmmmmm....
Thank You for sharing your code !! 
Honestly I am a complete noob when it comes to this stuff!!
I need to get Eclipse set back up with STM workbench again, I had to dump my install a while back due to a mistake I did that locked myself out of Linux, But that is no Biggy I just haven’t taken the time to do so yet.
I have never worked with STcube yet.
This were I am at, I was able to get the First four basic example GPIO demos to compile and Blinky to work in STW from this page,
http://stm32f4-discovery.com/2014/04/first-time-with-stm32f429-discovery/
All of the other ones using the LCD didn’t complie as these are all done in Coo Cox and they do work in that IDE but now I am doing everthing in Linux.
So porting everything over is a challange for me.
I did find one example that did work to intialize the LCD and display a picture that used EMwin but I don’t remeber what the URL was to post it here.
That one file will help me to learn how to make the LCD work as it was the only one I have that is functional with STW.
Your code will certainly help me as well with this if I can’t make it work.
I am not profficient at all in C but I do know a few of the basics as really wanting to work with this board is forcing me to learn.
What I do know is that I think that the section that assigns a value when a button is intialized needs to be in a call routine from the Main.c, This is how much I know as I had just grasped this concept of how it is done by reading many already coded examples ( such as the scope project to be mentioned below).
When I started with this board I knew nothing about C at the time and I took an online course on how to use the board, But we were using IAR’s ide and 30 days was just not enough time to learn anything.
A $2500 IDE to program a $25 board is a bit steep for me at this tiem.
SInce then I waited and struggled for over a year until I got Coo Cox functional and was able to complie and run some very cool examples that I found on the web.
Now I have this platform running as it just came out this year, and it works in linux were I plan to stay as long as I can.
I know occasionaly I will have to go back to CoIDE once in a while until I get a full understanding of things.
Two of My Favroties examples is an FFT example and a full Blown Oscilloscope project that uses on screen buttons.
I have the source code to these and they DO work in CoIDE but now I would like to make them work in STW and once I get that far then the rest will be easy.
Having some source code that is known to work on this platform helps I great deal and again I thank you for the sharing of your code to help me.
I also have the souce code for MMbasic that was ported to the STM32F4(07, 29) boards but I have not been able to get it setup and working yet, That project is under constant development for the PIC32’s, but the STM32 project has come to a halt for the time being.
They can be found at The Backshed forums here,

Sorry to go a bit Off Topic here, But maybe there is something there can help us with this board as well, and I figured that you might be interested in checking it out too.
I love this little board and I can’t wait until I know enough to help others with it as well as maybe get the latest greatest version of it as well!!
Cheers !!
