Polled Transfer Mode
[FreeRTOS+IO Transfer Modes]
Data DirectionPolled mode can be used with both FreeRTOS_read() and FreeRTOS_write().
DescriptionIn polled mode, data transfers are performed by busy waiting on peripheral status bits. Interrupts are not used.
|Polled Transfer Mode|
Polling is the default mode when a peripheral is opened. Not all peripherals provide a method to return to polled mode once it has been exited.
Polled writes will only return after all the bytes have been written to the peripheral, unless an error occurs.
Polled reads will only return after the requested number of bytes have been read from the peripheral, unless an error occurs.
