- [..]
- The MMC Extension HAL driver can be used as follows:
- (+) Configure Buffer0 and Buffer1 start address and Buffer size using HAL_MMCEx_ConfigDMAMultiBuffer() function.
-
- (+) Start Read and Write for multibuffer mode using HAL_MMCEx_ReadBlocksDMAMultiBuffer() and HAL_MMCEx_WriteBlocksDMAMultiBuffer() functions.
