Interrupt vector table read differently than written for Atmega128A
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

Please help me to add extra-values to my new project
Thomas Edison once said: In business, demand is invariably more important than supply. If demand doesn’t exist, supply is irrelevant. If demand exists, supply will eventuate....

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

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   fly over...

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...

PCINT - ask for help!
As a general rule, using interrupts for push buttons is a bad idea, due to the switch bounce... 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! Jim

I2C or serial communication between TWO atmegas of 3.3V and 5.0V
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...
