Discover how to program the Dreamer Nano using the AVR109 protocol with Arduino software and learn about bootloader and ICSP programming options.
Communication Protocol Description
It communicates using the AVR109 protocol.
Principle
The Dreamer Nano can be programmed with the official Arduino software (download). Select "Arduino Leonardo from the Tools > Board menu (according to the microcontroller on your board).
The ATmega32U4 on the Dreamer Nano comes preburned with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. It communicates using the AVR109 protocol. You can also bypass the bootloader and program the microcontroller through the ICSP (In-Circuit Serial Programming) header; see these instructions for details.
