Flexible interface (PRU-ICSS) for data acquisition using multiple ADCs

Description

June 3, 2019

This video showcases the PRU-ICSS interfaced to six 8-channel SAR ADCs (ADS8688), capturing data from all of the 48 channels at 32ksps/channel. Architecture of PRU implementation is demonstrated, achieving simultaneous sampling across multiple ADCs and coherent sampling to obtain high AC performance and minimal spectral leakage necessary for the data acquistion.
