dw-link - DIY debugWIRE debugger running on an Arduino UNO R3; Supported and tested MCUs. This is the list of all debugWIRE MCUs, which should all be compatible with dw-gdbserver. MCUs tested with ...

April Fools’ Day may have passed, but we really had to check the calendar on this hack. [Damian Peckett] has implemented an Apple ][, its 6502 processor, and a cassette port, all on an Arduino Uno.

The Arduino Uno-compatible board has an MCS-51 (often called 8051 instead) instead of the usual ATmega328P/ATmega168. Specifically, [ElectroBoy] uses the AT89S52 .

To allow debugWire in AVR Studio to function when run against an Arduino UNO, reset-enable must be cut to remove the capacitive load. Some precautions regarding the RESET line must be taken to ensure ...
