I'm using STM32F103RBT6 and try to make an slave SPI-Transfer over DMA using th latest STM32Cube.
The Master sends me 16-Bit Data Packets, i configured the SPI1 to 16 Bit, the DMA channels for Receive and transmit with half word, both circular.
My first Question: the Function "HAL_SPI_TransmitReceive_DMA" is generated with 8-bit pointers, i cannot pass a 16-bit Array! Why?
->I also use SPI2 with DMA for an external ADC with 8-Bit transfer.
I wondered, that all DMA Interrupts call the same HAL_SPI_TxRxHalfCpltCallback and HAL_SPI_TxRxCpltCallback.
Thanks for helping me!
