A lightweight Arduino library for encoding and transmitting DJI DBUS protocol signals (Robomaster format). Designed for ESP32 and other Arduino-compatible boards.

• Simple API for sending DBUS control signals
• Supports all standard DBUS channels (4 RC, 2 switches, mouse, keyboard)
• Optimized for ESP32 but works with other Arduino boards
• Handles all DBUS protocol formatting automatically

• Converting gamepad/joystick inputs to DBUS signals
• Creating custom wireless controllers for DJI systems
• Robotics projects requiring DBUS protocol

1. Install via Arduino Library Manager
2. Include in your sketch: #include <RM_DBUS.h>
3. Initialize with DBUS.begin()
4. Set channel values with DBUS.write_channel()
5. Transmit with DBUS.update() and DBUS.send()

#include <RM_DBUS.h>

RM_DBUS DBUS;

void setup() {
  DBUS.begin();
}

void loop() {
  DBUS.write_channel(1, 1024); // Set throttle
  DBUS.update();
  DBUS.send();
  delay(10);
}
