adc + overflow interrupt Just to be clear, we will not do your homework for you, we are professionals who write software for a living, so we expect to be paid for code provided, However, we will help you...
Regulating Inverter sine wave output using PI Oh PI as in PID control, I thought the OP was talking about 3.14… and that should already be in his lookup table!
never mind….
I’ll go away now

SoftwareSerial library Thanks Brian, I was only commenting on the OPs original posting of "needing" multiple USARTs. As I have no experience with rfid readers, I don't know how many the OP really...

However, it is common to use the PCINT to wake a sleeping AVR, and then poll the...

Can an ATMEGA328P do 16Mhz at 3.3V as VCC? If this is a commercial product, I would not exceed the DS spec's, but if its a one off hobby project, then it will work, at least for awhile!

If time is money… how much have you spent, not paying your annual support fee? Life is short, spend it wisely! Good luck with your project Jim

The reason you buy IAR is for their support, have you contact them with your issue? jim

I would question the decision to operate the two AVR's at different voltages, is it REALLY necessary? You can use voltage level translation, but it just adds complexity...
