Detailed Description
SWPMI Transmit/Receive functions.
=============================================================================== ##### IO operation methods ##### =============================================================================== [..] This subsection provides a set of functions allowing to manage the SWPMI data transfers. (#) There are two modes of transfer: (++) Blocking mode: The communication is performed in polling mode. The HAL status of all data processing is returned by the same function after finishing transfer. (++) Non-Blocking mode: The communication is performed using Interrupts or DMA. The end of the data processing will be indicated through the dedicated SWPMI Interrupt handler (HAL_SWPMI_IRQHandler()) when using Interrupt mode or the selected DMA channel interrupt handler when using DMA mode. The HAL_SWPMI_TxCpltCallback(), HAL_SWPMI_RxCpltCallback() user callbacks will be executed respectively at the end of the transmit or receive process. The HAL_SWPMI_ErrorCallback() user callback will be executed when a communication error is detected. (#) Blocking mode API's are: (++) HAL_SWPMI_Transmit() (++) HAL_SWPMI_Receive() (#) Non-Blocking mode API's with Interrupt are: (++) HAL_SWPMI_Transmit_IT() (++) HAL_SWPMI_Receive_IT() (++) HAL_SWPMI_IRQHandler() (#) Non-Blocking mode API's with DMA are: (++) HAL_SWPMI_Transmit_DMA() (++) HAL_SWPMI_Receive_DMA() (++) HAL_SWPMI_DMAPause() (++) HAL_SWPMI_DMAResume() (++) HAL_SWPMI_DMAStop() (#) A set of Transfer Complete Callbacks are provided in Non-Blocking mode: (++) HAL_SWPMI_TxHalfCpltCallback() (++) HAL_SWPMI_TxCpltCallback() (++) HAL_SWPMI_RxHalfCpltCallback() (++) HAL_SWPMI_RxCpltCallback() (++) HAL_SWPMI_ErrorCallback() (#) The capability to launch the above IO operations in loopback mode for user application verification: (++) HAL_SWPMI_EnableLoopback() (++) HAL_SWPMI_DisableLoopback()
