Hello,

I have bought this board and am using esphome with this yaml configuration file.

My led strips are flickering when I change the brightness level. Is there a setting to minimize this?

Thank you.

can you take a video? or can you test with another LED strip, different load.

same thing at my side....


its flickering on startup the LED. i remember with other esphome pwm controllers it was possible to fix that with frequency. do we have this option?

# Example configuration entry with external clock enable and clock source from ESP32
pca9685:
- id: pca9685_hub1
external_clock_input: true

# Individual outputs
output:
# generate PWM from ESP32 ledc
- platform: ledc
pin: 25
id: extclk
min_power: 1
frequency: 40MHz

- platform: pca9685
pca9685_id: 'pca9685_hub1'
channel: 0

this is demo code from ESPHome, you can try to change the "frequency" to another value for a test.
details: https://esphome.io/components/output/pca9685.html

It does not work with external clock config, led doesn't turn on...

what's your means?

I have the same problem? its flickering on startup the LED

OK. Problem solved. The default frequency for the I2C bus was too low

you have set higher i2c bus speed for pca9685?
