Driver SPI, PIC32MZ (EF) TransferSetup missing options.

[youpko]

I ran into a problem with the SPI driver (Synchronous mode) for PIC32MZ1024EFK.

I want to change the SPI clock rate at runtime using the DRV_SPI_TransferSetup() but the option to set the SPI hardware to 32-bit mode is missing. There is no enum for DRV_SPI_DATA_BITS_32.

After browsing through the DRV_SPI_WriteReadTransfer source I found that the DMA setup also would require a change.

• DRV_SPI_WriteReadTransfer checks for 8bits and if it is any other it is set to 16bit and does the word-to-byte conversion, it doesn't check for for the 32bit case.
• drvSPI*remapDataBits in initialization.c doesn't contain a remap for the 32bit case.
• _DRV_SPI_StartDMATransfer also has no setup for 32-bit DMA.

Thank you @youpko for reporting the issue. I will create an internal ticket to get this fixed.

@youpko , the SPI driver is updated to support 32-bit data transfers. I am closing this ticket. Feel free to re-open it in case you find any issues.
