CC3220: SimpleLink SDK v1.50.00.06 UDMA driver support for PingPong Mode

rperezti

Part Number: CC3220

Does the CC3220 SimpleLink SDK v1.50.00.06 UDMA driver have support for the PingPong transfer mode? I am porting an application from CC3200 to CC3220 and I don't see the equivalent functionality in the new UDMA driver. I am looking at the SimpleLink MCU SDK Doxygen Driver API Reference. It looks like the driver APIs only enable UDMA for the serial peripherals. There is no API for directly programming the UDMA for memory to memory transfers. Am I missing something or is this UDMA capability no longer exposed in the new drivers?

Thanks,

Hi Ruben,

If you are porting from CC3200, you can still use the driverlib directly exactly as was done before.
The TI Drivers that were added for the CC3220 MCPI SDK currently don't support the ping-pong functionality. It is expected to be added to the March 2018 release of the SDK.
