Teensy 4.1 ADC Library

[pi123]

How fast is the ADC sampling speed (sampling rate) in the ADC library for the Teensy 4.1? Specifically, VERY_HIGH_SPEED and HIGH_VERY_HIGH_SPEED?

Here is the link to an example in the library:

And this is the link to the parameter: http://pedvide.github.io/ADC/docs/T...ttings.html#af0d80a1aae7288f77b13f0e01d9da0d3

Sorry it has been a long time since I played with the ADC library. The T4.1 ADC should be identical to T4 speeds.

As for actual specific speeds, you will probably have to compute it and/or measure it, after specifying a lot more details.
Like ADC_CONVERSION_SPEED also things like how many bits, hardware averaging...

Best thing to do is to look at chapter 66 in the IMXRT reference manual. And for example section 66.5.4.6 is Conversion Time Examples...

Good luck. sorry that I can not give you any specific details. Maybe others can
