OP-Z RP2040

[apiel]

Hi, I couldn't find an email, so I create an issue. Your lib was very helpful to build https://github.com/apiel/opz-display The idea was to extend this https://www.reddit.com/r/OPZuser/comments/vxknwd/small_display_for_opz_knob/ that is using CC message with sysex. Unfortunately, it seem that RP2040 is too slow to handle all the sysex messages, then OP-Z is hanging and doing kind of weird stuff when pressing play. So I stepped back and use CC message again. I will try with ESP32 and see if can get better result. However, I also made an SDL version (for dev purpose, easier to test on Linux) using sysex.

I could not use your lib out of the box, because with Arduino, I was not able to use the std:.vector, also on embedded device, I try to avoid to allocate memory on the fly...

Thanks for sharing your code and links ;-)
