/** @addtogroup debug Debug UART
* @brief This section covers functions related to the debug UART, available on
* pin D1 of the 9-pin connector.
* @todo Refactor this as a USB CDC so that folks can debug over USB.
*/
* @warning These functions were used early on in development, before the TinyUSB
* CDC was implemented. You can now print debug messages to the USB console
* using printf, rendering this bit irrelevant. These methods will likely
* be refactored out in the future, in favor of a more full-featured UART
* on the nine-pin connector.
