Hello all, I am a first time user of the Teensy 4.1 board. I purchased it for a project I am tinkering with to hopefully measure 1-2 MHz signals with the built in ADC. So far, I have been trying my best to research how to increase the sampling rate to roughly 10 MS/s (5-10x Nyquist) on one of the ADC's on the 4.1. I've been reading on DMA and feel so overwhelmed to be honest. What I can gather is direct memory access bypasses the processor when data comes in, acting as a buffer. This then allows the ADC to chew through chunks of data as it is freed up (please correct me if I am wrong). However, the code has been very confusing to me. Most of the forum posts I see use a lot of jargon that I don't comprehend.
I would really appreciate it if anyone has had experience sampling at 10 MS/s and can provide some guidance. I am attaching my working program file that I had ChatGPT develop from the ADC_DMA.h file from the ADC library (it wasn't super helpful, of course).
