Arduino Firmware
The FarmBot Arduino Firmware performs the following tasks:
- Physically controls the FarmBot hardware by sending electrical pulses to the stepper motor drivers, reading voltages from pins, and outputting voltages and data to the Universal Tool Mount and peripherals.
- Communicates with the Raspberry Pi to receive G-code and F-code commands and send back logs and collected data.
- Monitors the rotary encoders as a closed-loop feedback control system to ensure that the stepper motors have not missed any steps. (Genesis kits only)
Installed automatically
If you just installed and configured FarmBot OS, then the Arduino firmware has already been flashed to the microcontroller and you can skip ahead to using the web app.
Any time FarmBot OS updates, it will flash the latest version of the firmware automatically as well.
Changing firmware
If you need to change your firmware because you chose the wrong one during setup, or you just upgraded your electronics, you can manually change it. Navigate to the firmware section of the settings panel and select the correct electronics board/hardware version from the dropdown menu labelled FIRMWARE. This will instruct FarmBot to flash the new firmware. After flashing is complete, you will need to FarmBot to complete the initialization.
Reflashing firmware
If you are experiencing issues with your firmware, or just installed replacement electronics without firmware installed, you may manually reflash the firmware. Navigate to the firmware section of the settings panel and click . After flashing is complete, you will need to FarmBot to complete the initialization.
Using custom firmware
Using custom firmware is only recommended for software developers. For more information, see the developer docs.
