Hi,
I am making a project where in I am connecting few LEDs with my STM8 Discovery Board (PA3, PD3, PD4) and setting the mode using the on-board button (PB7). The issue I am facing is that I am able to toggle to Flag = 2 (with for loops for phasing the 3 LEDs) but the button becomes unresponsive after that. I need to be able to go back to Flag 0 and Flag 1.
I am a beginner so there is a lot of hit & trial that I have done but the code is doing what it is supposed to do except this part. Would appreciate any guidance on this pls.
TIA!
