This is the source code of the firmware shipped with your 1Sheeld board. It is an implementation of a custom version of the Firmata protocal ported to ATmega162. It supports some of Firmata's messages like digital messages but lacks capability query, analog, I2C and servos messages.
The repo is an Atmel Studio project, but we have plans to make it as a generic C project so you can build it easliy on platforms other than Microsoft Windows with a standard MakeFile.
- Low Value: 0xFD
- High Value: 0xD8
- Extended Value: 0xFB

The ICSP pins are exposed with a 6-pin header on the bottom of your 1Sheeld board. You can easily connect any ATmega programmer and upload your own version of the firmware.
Note: 1Sheeld is equipped with a bootloader that enables us to push updates to the firmware from the app. If you attempt to upload this firmware and erased the chip, you will lose this functionality.
You can generate the documentation by installing and running doxygen
on the repo's root directory.
