How to use timer interrupts for detecting multiple button press.

[Killstreet30]

Hello,

I am currently using an External Interrupt style program to detect multiple button presses but it doesn't work and I wanted to know how I can use timer interrupts for detecting multiple button press. Please share code. Thanks!

I wouldnt use EXT interrupts for that.

But if you really wanted to , it should work, unless you messed up preemption and interruption priorities
