Hello,
This is not the best B4R code to scan matrix keypads, it is just a try, just wanted to share the idea with you, you may like to enhance and modify it as needed.
but i have a question here, I could not do this, 'wait for a key press', the loop blocks scanning timer. any ideas to do so? is there a way to direct program to wait for something to happen like pin state or key press in my case, then branch it again according to results!
thanks

B4X:
Do Until KeyValue = KEY_0
Loop
Log("a key is pressed")thanks
