thanks @mongrol . I have searched for this control board but didn't found it. I love the ways some oled display are mount between the rings and encoders.
Can you explain how they're are reading the 24 increment state of each encoder?
here is a one example how to transmit datas by uart between an arduino and axoloti. The axoloti part needs some improvements. If I have tried to comment each step so everyone knows, what's going on.
message to be send to arduino are:
l/ value1 value2 value3 value4 ("l/" at the beginning signals a message for leds section followed by 4 bytes value.
x/ HELLO WORLD!; ("x/" at the beginning signals a string message. ";" marks ending of a string message. Everything between will be printed by arduino serial…
the arduino sketch needs two serial ports but you can edit it to work with only one arduino serial port. I have tested this sketch with stm32f1 based board running as stm32duino.

Sometimes the serial communication got stocked and it seems that serial messages are printed out in four pack sequence. So something is wrong with byte handling or storing…
