I am looking for an experienced Arduino developer to help me generalize my i2c code. I am using a specific Arduino board, which I will specify. I have some code that actually manages 16 i2c OLED screens using 2 i2c muxes, but want to code a program that manages the 8 possible muxes by address. The code receives some midi sysex signals (screen number, text), and sends it to the corresponding screen. So in summary I want to convert the code supporting 2 muxes into a generalized one for 8 muxes, stored into an array of references, and tidy up the code in general. The original code will be shared accordingly.
