OctoPi - LED matrix control for computational phase contrast

We are using inverted SQUID stages with the CEPHLA LED matrix for transmission bright-field - as first introduced in the OCTOPI model.

My question is: Does anyone have pointers to make the LED matrix work properly, especially for computation phase contrast microscopy?

So far on our microscopes, the LED matrices (of different generations in terms of cable connections to the controller unit) are working for brightfield microscopy, but most of the drop-down variations don’t work: like switching on specific parts or specific colours. Some functions work, but most don’t and some are shuffled. Issues have persisted so far between software versions if I am not mistaken. Any advice is welcome before we try solving it on our own.

Are you using the original octopi controller or the more recent squid controller? With hardware from 2023 the LED matrix should work as expected without extra config. Let’s move the discussion to slack to see if we should get you a new controller/led matrix/cable?
