I am trying to use my RPi PICO to control a BLDC ESC. Using a servo tester it works perfectly, but I want to be able to use this with my PICO and with a trigger/spring potentiometer. Basically it will take the readings from the POT and send the proper signal to the ESC to control the speed.
EDIT: I was able to get the motor/ESC to work but only at 500hz. Then when I throttle all the way up, the motor maxes out for a few seconds then turns off. When the throttle/pot is all the way at zero, the ESC beeps indicating no throttle signal. So I believe the duty cycle is off or does not detect the signal at the frequency. None of this happens with the servo tester. Any thoughts on how to fine tune the frequency/duty cycle?
import board import analogio import pwmio import digitalio from adafruit_motor import servo import time potentiometer = analogio.AnalogIn(board.GP26) pwm_sig = pwmio.PWMOut(board.GP14, frequency=500) #Just to see if my PICO is powered on during VSYS red_led = digitalio.DigitalInOut(board.GP11) red_led.direction = digitalio.Direction.OUTPUT red_led.value=True while True: pwm_sig.duty_cycle = potentiometer.value
