farmbot-arduino-firmware
This software is responsible for receiving G-Codes from the Raspberry Pi, executing them, and reporting back the results.
Technicals
Created with eclipseArduino V2 - For more details see http://www.baeyens.it/eclipse/
Development build instructions
This firmware is automatically bundled into FarmBot OS. The following instructions are for isolated Arduino development only.
NOTE: We tag releases when they are stable. The latest version (on master) is not guaranteed to be stable.
See releases to find a stable release.
OPTION A: For less stable "edge" version:
git clone https://github.com/FarmBot/farmbot-arduino-firmware
OPTION B: For stable release v6.4.2:
git clone -b 'v6.4.2' --single-branch https://github.com/FarmBot/farmbot-arduino-firmware
Options for compiling and uploading:
- Arduino IDE:
- Open
farmbot-arduino-firmware/src/src.ino
. - Select the
Mega 2560
board in Tools > Board. - Uncomment only the desired board in
src/Board.h
. - To compile and flash the firmware onto the device:
- Connect a device via USB.
- Select Sketch > Upload or click the upload button.
- To compile without flashing:
- Select Sketch > Export compiled binary.
- The
.hex
file will save to thesrc
directory.
- Open
- Make (Linux)
- Download the Arduino 1.8.11 IDE and unpack to the
/home
directory. cd farmbot-arduino-firmware
- To compile:
make
.hex
files for each board type will save to thebin
directory.
- Download the Arduino 1.8.11 IDE and unpack to the
- VSCode
- Set Arduino path and board type.
- To compile and flash the firmware onto the device:
- Connect a device via USB.
- Select Arduino: Upload.

IMPORTANT
Farmbot will NOT move until the configuration has been approved. To approve manually, send 'F22 P2 V1 Q0'
To move, use the command 'G00 X0 Y0 Z0 Q0' where you type in the coordinates just after X, Y and Z.
