B4R Question Matrix keypad scanner problem

[Mostez]

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!

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

thanks

No. You shouldn't try to hold the main (and only) thread. You should instead raise an event when something happens.

OK Erel, in this code I raise an event (KeyPressed) may I ask for simple example how to trap such event, just want to implement something like that;

print(yesNo)
if pressed yes
Sub1
else
Sub2
end if

Thanks so much

I plan to create a library for keypads. It will be available in two to three weeks.

 

[Mostez]

It will be so great,

Thanks

I'm still waiting for it to arrive. It is a holiday month here so everything is slower.
