You can see that they confirm both the context paramter, as well as where their USART tasks state machine are to handle the event and move the state machine along. Multi-master mode is not supported. Since it has 1 bit to enable or disable a channel, there is only 1 register needed, and the master merely writes the register data after the slave address, skipping the register number. The RTOS extensions are enabled by default, the RTOS extensions allow the Aria task to run as a stand-alone, blocking task and provides thread-safe APIs for sending events from other tasks to the Aria task. These routines are hardware independent and can be used with any MCU. MPLAB Harmony is a comprehensive, interoperable, tested software development framework for Microchip’s PIC32 microcontrollers.
