The timer value stays zero in the while loop, and … WebNov 3, 2014 · The problem is that delay () is a "busy wait" that monopolizes the processor. During a delay () call, you can’t respond to inputs, you can't process any data and you can’t change any outputs. The delay () ties up 100% of the processor. So, if any part of your code uses a delay (), everything else is dead in the water for the duration. howells cream king https://amdkprestige.com
