Can I program AVR Microcontrollers using Arduino Development board with AVR Studio? I know and I can program any AVR microcontroller with Arduino IDE and Arduino Uno board. Can I use Arduino board with AVR Studio? Or I have to buy an AVR Development board?
You can use Atmel Studio to write code for the MCU(s) on the Arduino boards. If the IDE itself does not support uploading the code to the Arduino then it is still possible to use AVRDUDE or BOSSA to upload it via the command line.
