When sending an i2c buffer on the i2c bus, if the follower is not connected to it, Hans will crash.
Need to add a better error handling -> Try, catch.

Hi,

this looks great!!

I'd love to fork this project and create a narrow-format Eurorack module breaking out the USB sockets and MIDI IO on either/and DIN/TRS sockets.

Do you plan to release the schematic or board files for the hardware here?

Feel free to move this to a discussion, if you turn on that feature for the repo, as it's not strictly an "issue".\

Keep up the great work!

⚠️ Connecting the Raspberry PI directly to the ER-301 module or even to the same i2c bus is a source of problems. If the two devices are not started simultaneously, or if the ER-301 is powered on after the RPI, the Raspberry Pi will prevent the ER-301 from starting normally.

(The ER-301 uses the bus for UART during its startup, it pulls the line down => Conflict with the RPI i2c hardware gpio)

To overcome this problem, it is prefereable to create an external circuit including two 4.7k pull-up resistors and use another set of GPIO on the Raspberry for i2c (aka. "Software i2c overlay") rather than the "hardware i2c gpio".

Hans only sends "setters" and cannot retrieve from modules aka. "getters"

The boot time of RPI Zero W is approx. 50 seconds. This needs to be improved.
