Set up with PX4
Hardware Setup
Connect the Pixy LR UART (CTRL port) to the Telem2 on the PX4 system
Setting on the remote control
Pixy LR is compatible with the Remote Control (RC) that supports the QGroundControl app (QGC). In this manual, all settings are made on Herelink Remote Control; the other controller does the same.
SBUS channel settings
Pixy LR needs to set up 2 channels to control the gimbal: one channel is for controlling rotation, and the other is for choosing the controlling axis.
Set up channels controlling the gimbal
Gimbal rotation control channel: CH6 (or any channels); use the wheel button on the Herelink remote:
Gimbal axis selection channel: CH8 (or any channels); use the camera button on the Herelink remote.
Setting parameters
Firmware Requirement
• Version: update to the latest version. • Support Mavlink v2 protocol
Set up the telemetry baud rate
Pixy LR connects to FC at the baud rate of 115200. In case of connecting Pixy LR to FC at any telemetry, note the telemetry setting at the corresponding baud rate.
Example for telemetry 2:
• MAV_1_CONFIG: “TELEM 2” • SER_TEL2_BAUD: “115200 8N1" • MAV_1_FORWARD: "1"
Set mount parameters
• MNT_MODE_IN: “RC” • MNT_MODE_OUT: “Unknown: 2” • MNT_RC_IN_MODE: “1” • MNT_MAN_PITCH: “AUX3” // PAN/TILT choose axis • MNT_MAN_ROLL: “AUX2” // Zooming, High: Zoom in, Neutral: Stop, Low: Zoom out (current: only using mode control by angle) • MNT_MAN_YAW: “AUX1” // PAN/TILT move • COM_RC_IN_MODE: “Unknown: 3”
Set RC map channels
• RC_MAP_AUX1: “Channel 6” // set channel 6 to AUX1 (Yaw) • RC_MAP_AUX2: “Channel 7” // set channel 7 to AUX2 (Roll) • RC_MAP_AUX3: “Channel 8” // set channel 8 to AUX3 (Pitch)
