Upload AVR Assembler to an Arduino UNO

ArduinoAVRUploader – I’ve bundled the command bellow into a useful utility. The Arduino IDE must be installed for this to work. It’s developed in VS2013 so you might need to install a runtime.

A lot of the internet will tell you that you can’t program an arduino uno in assembler. You can can, but you can’t use the default IDE (which is fairly limited anyway). I didn’t work this out unaided but unfortunately I’ve forgotten where I found the info. Xloader was certainly a step along the way but sadly it doesn’t work with the uno (or at least the version I have).

You just need to compile you code to a .hex file using AtmelStudio and then run the command:

C:\Program Files (x86)\arduino\hardware\tools\avr\bin\avrdude.exe -C"C:\program files (x86)\arduino\hardware/tools/avr/etc/avrdude.conf" -patmega328p -carduino -P\\.\COM3 -D -U flash:w:"{path to your file}":i

This is how the Arduino IDE uploads its programs so it preserves the bootloader.
