I am trying to use HAL_SPI_Transmit(.) for 16 bit data transmission.
I have configured the SPI using STM32Cube as 16 bit data size
(with hspi2.Init.DataSize = SPI_DATASIZE_16BIT
).
I tried to send data in 16 bit with:
uint16_t DataToSend[10]={...};
HAL_SPI_Transmit(&hspi2,DataToSend, 2,TIMEOUTSPI);
But the function HAL_StatusTypeDef HAL_SPI_Transmit(SPI_HandleTypeDef *hspi, uint8_t *pData, uint16_t Size, uint32_t Timeout)
needs specifically for uint8_t*, and it returns the following error:
error: #167: argument of type "uint16_t *" is incompatible with parameter of type "uint8_t *"
So how can I send 16 bit data using HAL_SPI_Transmit()
?
I found this link but only the bug was discussed and not the way to use the function. So my question remains.
I have searched the net without any luck. I am rather new to STM32 so the answer may be obvious to you.
