CCS/AWR1642: EDMA related functions documentation

I'm facing difficulty understanding a few functions (related to edma and ping pong buffers) in the TI code for the Short Range Radar Application. I cannot find any documentation for some of the functions, like

EDMAutil_triggerType3(obj->edmaHandle[EDMA_INSTANCE_B], (uint8_t *)(&obj->radarCube[cubeOffset]), (uint8_t *)NULL, (uint8_t)chId, (uint8_t)SRR_EDMA_TRIGGER_ENABLE);

Where can I find the documentation for these functions?

Chaitanya,

You can find information about the different EDMA triger types in the dss_config_edma_util.h file.

This can be found at this location in the SDK 2.0.0.4 release: C:\ti\mmwave_sdk_02_00_00_04\packages\ti\demo\xwr16xx\mmw\dss\dss_config_edma_util.h

Regards,
Kyle

Chaitanya,

You can also refer to this application note to get a better understanding of the DSP subsystem included the ADC ping-pong buffer.
