Hi, I'm trying to sampling a sinusoidal wave with frequency of 60Khz, put the ADC tooks about 7us to do one conversion. (using fadc = 24Mhz, continuos mode and only one channel enabled).
My question is: What's the minimum time between samples on ADC of STR912F?
Without reading your datasheet, I would guess that the answer is no.
The advantage of DMA is normally just a lower the CPU load. In this case, I'm pretty sure that the limiting factor is the ADC - the number of clock cycles/conversion when run in continuous mode.
