MAVLink is a lightweight communication protocol for communication between drones (and/or ground systems) and their components.
The underlying MAVLink protocol library automatically gets updated once a month. Correspondence between the library release and MAVLink release can be seen in the versions.yaml file.
Official MAVLink documentation: https://mavlink.io/en/.
Search for "MAVLink" in the Arduino IDE library manager and install the library.
arduino-cli lib update-index
arduino-cli lib install MAVLink#include <MAVLink.h>
void setup() {
Serial.begin(57600);
}
void loop() {
// Send HEARTBEAT message to Serial once a second
mavlink_message_t msg;
uint8_t buf[MAVLINK_MAX_PACKET_LEN];
mavlink_msg_heartbeat_pack(1, MAV_COMP_ID_AUTOPILOT1, &msg, MAV_TYPE_QUADROTOR, MAV_AUTOPILOT_GENERIC, MAV_MODE_FLAG_MANUAL_INPUT_ENABLED, 0, MAV_STATE_STANDBY);
uint16_t len = mavlink_msg_to_send_buffer(buf, &msg);
Serial.write(buf, len);
delay(1000);
}The default used MAVLink dialect is common. You can use another standard MAVLink dialect like this:
#include <MAVLink_ardupilotmega.h>#include <MAVLink_matrixpilot.h>See examples in the examples directory.
