Hello. I'm not sure this post is in the right forum ... I use ATMega8-16 rated at 16 MHz and I'm surprises to see that ADC frequency is not conform to spec. Error is probably of my own ... Frequency is theorically 16 MHz / (2^^n) with in normal running 13 clocks per data numerized. In fact, according to n = 1 ... 7, I found on scope (and also in simulation with Avr Studio) that total time used for one digitalization is 2 ^^ n multiply by

26, 20, 17, 15, 14, 14, 14 with n = 1 ... 7. Where is the error ?
