I'm designing a new PCB that features an ATmega328p and ATtiny80. Both MCUs are SMT and populated by a turnkey manufacturer.
They communicate over I2C with the 328p being the master.
The tiny runs a stepper motor at whatever speed the 328p tells it to.
I am planning to program these using the Atmel ICE and Atmel Studio.
I've never used Atmel ICE, ATtiny, or Multiple MCUs in a single board before so I've very new to these areas.
What would the best way to program these be?
Would I just be able to wire both MCUs to the 6 pin programming port and the software is able to detect which MCU to upload to?
