Canvas Mode is compatible with Betaight Congurator 4.3.0 and later. Conguration
steps for Canvas Mode vary depending on the software version. Refer to the
conguration guide for the version you use. Below are the basic conguration steps.
1. Hardware connection: Connect the UART RX port of the air unit to one of the UART TX
serial ports (UART4 is used as an example) of the ight control board.
2. UART conguration: Open Betaight Congurator and select Ports. Turn on the MSP
switch for the corresponding UART TX serial port (UART4) and set baud rate to
115200. Click Save and Reboot.
If Betaight Congurator 4.4.0 or later is used, set Peripherals to MSP+Displayport. In
this case, you can skip the CLI conguration below.
3. CLI conguration: In Betaight Congurator, select CLI and execute the following
commands:
a. Set osd_displayport_device to MSP:
set osd_displayport_device = MSP
b. Specify the MSP serial port number, which equals the UART TX serial port number
minus 1. In this example, set the number to 3.
set displayport_msp_serial = 3
c. Save and exit:

4.7 EIS Usage Notice
Issues
• Video image shakes when RockSteady is enabled.
• Mechanical vibration at certain frequencies results in abnormal EIS (electronic image
stabilization) performance of the air unit.
Causes
• IMU resonance
◆
The default ESC (electronic speed control) PWM (pulse-width modulation) control
frequency is 24 kHz, and the camera IMU frequency is around 24 to 30 kHz.
Without eective vibration absorption, motor vibrations can transfer to the
camera IMU, causing resonance due to frequency overlap. The resonance will
aect the IMU data accuracy and EIS performance of the video stabilization
application. * As a result, the processed video image shakes, but the liveview
image is not aected.
