Attached is a demo project showing DellSig_ADC acquisition of 1000 points to RAM buffer using DMA. On button press, hardware trigger opens DMA channel until RAM buffer is full, then interrupt is fired to begin plotting acquired data. Once data output is complete, system is ready for the next trigger (button press). Button's Pin_17 is set to Resistive pull High. Button switch Debouncer is optional. Instead of the switch button, a digital pulse can be used to trigger the acquisition.
Project utilizes optional PSoC Annotation Library v1.0, which can be found here:
Thank you for your lib and answer! I'm inspired by this and changed my project accordingly! Basically I've see same results as prior - shortened differential inputs to cable shield show raw samples near by 65536. I've applied 1000mV and now it works as expected. Probably I faced a numeric overrun before ...
