Hi, I'm trying to work with the SAI HAL interface, i have set the black frame to 64 bits wide and the block slot size to 32B.
When using the HAL_SAI_Receive() function, what does the length parameter represent?
For my solution i am sending 2 32bit slots in 1 64 bit frame, therefore is the length parameter set to 64 bits?
Here's the SAI function in question:
/**
* @brief Receive an amount of data in blocking mode.
* @param hsai pointer to a SAI_HandleTypeDef structure that contains
* the configuration information for SAI module.
* @param pData Pointer to data buffer
* @param Size Amount of data to be received
* @param Timeout Timeout duration
* @retval HAL status
*/
HAL_StatusTypeDef HAL_SAI_Receive(SAI_HandleTypeDef *hsai, uint8_t *pData, uint16_t Size, uint32_t Timeout)
It is found in stm32l4xx_hal_sai.c line 1133.
My setup is an Nucleo-64 STM32L452RE.
Many Thanks!
Richard
