Question: HUB75 refresh rate too slow (flicker) with 4 panel chain 64x32 on Pico 2 W

[hubertmeier]

The refresh rate for 4 panels in a chain is too slow, flicker is a problem, especially if there is much daylight.

Is the core speed of the 2350 at maximum speed? I found no way to increase clock speed.
Is the driver in circuitpython optimized for the pico2 W?

one single panel 64x32 works really good, with four panels would a higher refresh rate be nice ...
one single 64x64 is still ok.

the reason for flicker is clear, but higher refresh rates would solve the problem.

Thank you
