Hello all,
I am sampling the ADC so I can perform some Time-of-flight measurements for ultrasound signals. I wanted to increase my sample speed, so I used DMA to place the information into the buffer. But as far as I can tell, DMA can't access the CPU Timers or the EPWM timers, which means I can't also place the timing information for each sample into a buffer. I realize I can use the samples themselves as timing information, but then I need to continuously sample, which takes up a lot of memory.
Is there something that I am missing with how to do this?
Thanks,
Matthew
