Resolved! Two DMA buffers for alternate ADC samples on the same pin

I sample a 1000Hz periodic signal twice  each period. At 50us after the start of the period for samples A and after 850us for samples B with a single ADC and a single channel. I trigger the ADC with a delayed PWM (Combined PWM1 on a G431) and the res...
