Description:
The PCA9685 chip allows for flexible phase angles. Currently the component uses this ability to set the phase angles equidistantly for all output channels. So 3 output channels would have a phase angle of 0°, 120° and 240°. This however can cause flickering of the LEDs when animating / fading, because when the output changes and the start angle is higher than the end angle of the output the chip will need an additional frame where no signal is outputted (as indicated by the (datasheet)[https://cdn-shop.adafruit.com/datasheets/PCA9685.pdf#page=20]
This pull requests documents a new configuration option
phase_balancerwith the options oflinear, which keeps the current behavior and is the default. Andnonewhich sets all phase angles to 0°, so that the problem described above does not happen.Pull request in esphome with YAML changes (if applicable):
