Please keep the possibility to freely choose internal or external and up to 32Mhz on both options. We have custom designed hardware (with 32MHz crystal) with the 328 for which...

Good point. Btw, you even loose 2K due to the EEPROM emulation.

Please, let’s not start breaking things. If we want this core to be widely used it must be stable. > That's a good point @LaZsolt, this chunk for example is...

@darkautism Does your code support the change of clock source and clock speed?

That would be nice, because running the chip at 32Mhz breaks certain Arduino libraries. The change to external clock source is also beneficial in certain cases.

I can confirm, 12 bit seems to be default. I only see 4064 as max value though, not 4096.

Well, 12bit being 4096 (including 0) of course, but that is not what I observe. The highest value I measure is 4064.

Good catch @LaZsolt !

@LaZsolt I have a question regarding this gain correction thing. I'm using 2.048V as reference and set the ADC to 12bit. When I want to calculate expected ADC values like:...

Thanks. Will take 4064 in all calculations and verify with multimeter. You're right about the ref voltage of course. (The formula image is not mine, I grabbed it off the...
