Multiple Button Issue #76

Open patrickgardella opened 4 months ago

patrickgardella commented 4 months ago

I am running into problems using Button2 with multiple buttons. I thought it might be something I was coding wrong, but I have this exact same problem with the "Multiple Buttons" example that comes with the library.

I have two buttons connected to an Arduino Uno Rev 3 on pins 7 & 8. (The other lead to the button is connected to the ground pins.) I'm connected to my Linux desktop through /dev/ttyACM1 (USB).

Everything works fine for about 15-20 seconds, as I randomly press the buttons. Then things begin to slow. I can press Button A multiple times, and only see one line print in the Serial Monitor. Or alternate and see an occasional A or B show up. Maybe 1 line out of 8 or 10 button pushes.

I don't think its the serial connection or monitor, because my original code uses LEDs to indicate a button has been pushed, and they show the same random push behavior.

And If I just test one of the buttons at a time, using the "Single Button" example (on pins 7 or 8) everything is fine and works as expected. I don't change the wiring, only the example code I'm using.

I'm working on a build where I'll have many buttons, not just two, so I want to make this work.

How can I better debug this to figure out what is going wrong?

FWIW, here is the diagnostic details from avrdude:
