Hi,

I have to accomplish the following tasks:

1) Acquire a sequences of ramp signals, sampled at 1Msps and 24 bits per samples (we are using an ADC with parallel interface connected to the XINTF and DMA, see attached figure

3302.ti.pdf);

2) Since each ramp last 1ms, we have to average 1000 ramps (1 s of data);


3)The avergaed ramp has to be further processeed.

Any suggestion on how to design interrupts, ISR and DMA (e.g., if using ping-pong)?

Best
