How to set pixhawk

(wdodo) #1

I want use another type light to change the BR light to get more lumen,
The light controller is like this
It supports 0-5v control or PWM(which not suitable normal pixhawk PWM).
How can I set pixhawk to change the frequency and duty. or control pixhawk to out 0-5V
or I should use other transform board

You can use a transistor to convert the signal from 3.3V to 5V, to change the pwm frequency you can use SERVO_RATE and if you don’t want to use pwm, check the RELAY_PIN* parameter (works like a digital signal ON-OFF).
