- * \ingroup pb_drv
- * \defgroup pb_drv_rp2040 RP2040
- * \brief Raspberry Pi Pico and Pico W driver
- *
- * \note This file is no longer inside `lib/pbdrv/drv/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.
- *
- * \warning The workaround implemented in this driver was already kind of
- * messy, and **a different microcontroller should be used for the main
- * controller instead**. Please see the handover document for more details.

-/**
- * \note While the RP2040's datasheet claims it supports multi-master
- * configurations by implementing bus arbitration, it does not natively support
- * a mode where 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.
- *
- * \warning 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).
