[SOLVED] push buttons and virtual wire library conflict??

Projects General Guidance
1

hello everyone
I have a project going on where some LEDs are turned on/off and a signal is transmitted via those RF 315/433 MHz Trans-receiver. Some parameters are controlled with 3 pushbuttons.

Here is the thing: push buttons readings are ok with a testing code where I just press the buttons and get the readings. BUT if implement the rest of the code, push button readings become unstable (bounce).
More precisely the conflict occurs with the virtualwire library: I figured out adding parts of the final code to the testing code, one at the time. Every goes nuts with the setup instuction of the virtualwire library

any suggestions? any similar experience?

I also tried debouncing libraries as bounce2, but i did not work for me

here is the code

You do know VirtualWire takes over one of the timers?
"Caution: VirtualWire takes over Arduino Timer1, and this will affect the PWM capabilities
of the digital pins 9 and 10."

Will that be a problem with your other libraries?

I know about the timer, I had to switch to the timerfreetone library because of that. Anyway I don't need pwm on 9 and 10, since they have been used as digital (1 or 0) connecting push buttons to the pullup resistors.
Or do you have alternatives? Please consider I wouldn't change the wiring since Everything is on a pcb I made.

Thank you for the tip

don't how and why, but I solved changing the virtualwire library with the RadioHead library
