Pardon my english.
The problem: I am utilizing the AD9850 sine wave generator to input a wave into the Arduino Due ADC and I want to sample this signal beginning from phase angle 0.
I was able to get a code from the community to convert the signal using the DMA, but it always sample beginning at an arbitrary point of the wave, which is expected.
The solution I've come: build a pulse generation from a zero crossing circuit and use digital ports to put an ADC convertion starting point.
The question: Is there any solution that do not involve extra hardware such as the solution I said?
I hope you have understand the point and I thank in advance.
