All, I am needing to find out the current DMA source address after detecting a "trigger", so that I can establish where in memory the pre-trig and post-trig memory start and stop that contain my ADC sampled data.

I must not be using the CyDmaTdGetAddress function correctly, or else it is a function that I don't need to use, because it doesn't seem to be an address in the SRAM (0x20008000 - 0x2000FFFF) area (as per DMA data sheet page 2).

Any ideas??
