 		 #169247 - ADC read function just stop working
Responding to: ???'s previous message

in some how the ADC read function just stop working

No, it doesn't "just stop working" - there will be a reason.

eg, what happens if there is no character available when you call getchar...?

it only works if I either comment "c = get_char(); or get character in the way I showed in the previous post.


OK, so you might choose to set the getchar issue aside, and go back to polling.

But your polling method is still incorrect - as mentioned previously.
