4MSPS Dual-Channel DMA-ADC: Capture Quad Signals & Reconstruct Waveforms

00:11:20 | 04 AUG 2025

This demo showcases PA15 and PA16 simultaneously acquire quadrature signals on PB3 and PB2 at 4MSPS/channel, with DMA auto-transferring 1000 samples to RAM on fixed to block address mode. Export raw data via UART to Excel, restoring 90° phase-shifted waveforms.
