- * This is the RP2040 puzzle bus driver. This file is no longer inside
- * lib/pb//rp2040 as it is tightly coupled to both the pico-sdk and
- * freertos functions. I have tried to get FreeRTOS to play nicely with the
- * CMake subproject layout, but the pico-sdk and the rp2040 port of freertos
- * both rely on CMake's import() functionality, which makes using FreeRTOS in a
- * libary context extremely messy.
- *
- * The workaround implemented in this driver was already kind of messy, and a
- * different microcontroller should be used for the main controller instead.

- * While the RP2040's datasheet claims it supports multi-master configurations

- * it is configured as a (multi-)master with a slave address, such that it can
- * be addressed by other multi-masters. This function includes a hacky
- * workaround that teporarily sets the RP2040 to I2C master mode to send a
- * message, and then restores it back to slave mode.
- *
- * This approach results in some received frames being (partially) dropped in
- * the time period between the invocation of this function and the bus becoming
- * idle (and the message is sent).
