Implement LINDA as I2C Slave #9

As of Micropython 1.22.2, there is no way to initialize an I2C object with the target RP2040-based microcontroller as a slave. There are other Micropython ports that allow this functionality -- specifically boards built on STM32. You can see the i2cslave.c file in the Micropython repo here.

This would entail making custom rp2 Micropython firmware and flashing that to the LINDA Pro Micro and writing code to use the new functionality.
