Question

Add numeric keypad display

I'm just starting to use touchGFX and am trying to figure out the best way to design the functionality I need. I need a numeric input panel along with a display of the number that was entered. I need 10 digits (0-9), decimal point, a backspace, and an Enter key. The display portion needs to display a number up to 999.999. I see individual buttons available in touchGFX Designer, as well as a full keyboard, but not a numeric keypad.

 What is the easiest/best way to get to this functionality. My eventual target is an STM32F469 Discovery board, although I'm willing to upgrade to something faster if needed.

 Thanks

Hi @brian239955_stm1​,

Start by checking out the Keyboard example we have through the Designer. Then get back to me with what you feel you're missing, okay? You should be able to adapt the example to something numerical instead. Thanks!

Hi @brian239955_stm1​,

Any update on your end? Did you try the standard Keyboard example?

I am looking for a simple Keypad input as well.  I have implemented the "KEYBOARD" example and understand how to use it, but do not understand how to change it from a keyboard to a keypad.  Any help would be greatly appreciated.
