Detailed Description

UART/Serial driver implementation for ChibiOS arch.

ChibiOS has a high level Serial Driver, for Paparazzi it is more convenient than pure UART driver (which needs callbacks etc.). This implementation is asynchronous and the RX thread has to use event flags. See ChibiOS documen- tation.
