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.

[admin]

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

[janosch1337]

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

- 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.

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

[admin]

what's your means?

[chudystg]

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

[chudystg]

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

[admin]

you have set higher i2c bus speed for pca9685?
