ADC scaling
« on: July 30, 2014, 12:57:23 pm »
I am using one of the original Digisparks and am having a scaling issue
the voltage range seems to have a max input of about 1.1V, is it possible that by default the CPU is using the internal reference instead of VCC?
How would I change it.
thanks
Steve

I think we need more details. Can you post some code, and tells us what pin you're reading from?
