I read that using internal RC oscillator is not reliable when "timing accuracy" is needed. I am using tiny2313, and I need to use uart at 2400 baud rate, does this application require "timing accuracy"? :?: I prefer to use internal RC oscillator to leave XTAL pins as I/O.
How can you define timing accuracy?
How does operating temperature effect 8 MHz internal RC oscillator?
Thank you in advance...
