We love our AVR Dragon programmer. It is a small board with a lot of functionality: in-circuit serial programming, JTAG, debug wire, and high voltage serial programming. Unfortunately, out of the box ...

As per the documentation both should work. But it seems to me I can not get dragon_dw to work properly once I enable debugWire on the Uno clone with ATmega328P using an AVRISP mkii and avrdudess GUI.

Atmel’s latest AVR microcontroller development tool supports all programming modes and includes on-chip debugging for over 30 MCUs has a price tag of $49. The AVR Dragon supports all programming modes ...

The procedure for calibrating the RC oscillator of an AVR8 microcontroller is described in the application note ATMEL AVR053. This application note does not explain the implementation of this ...

If you’re like us you’ve got quite a few prototyping tools that are bare PCB boards. If you’re using them a lot you might want to protect them with some type of case but the lack of mounting holes can ...
