Teensy 4.1 not accessing a1-a17

[eagleman]

Did I miss something? I cannot get good numbers out of accessing A14 - A17. Do the "ADC.h" or "ADC_util.h" libraries need updating or changing?

here is the beginning of mt setup:
#include <ADC.h>
#include <ADC_util.h>
#include <Time.h>
#include <TimeLib.h>
#include <elapsedMillis.h>
#include <Adafruit_GFX.h>

#include <Adafruit_SPITFT_Macros.h>
#include <gfxfont.h>
#include <Adafruit_ILI9341.h>
#include <XPT2046_Touchscreen.h>
#include <SPI.h>
//File root;

is latest TeensyDuino 1.52 installed?

This is a third party library and it looks like @pedvide has not yet finished adding the T4.1 support.
But it looks like he knows about it and has done some work for it, as I see an open Pull Request:
https://github.com/pedvide/ADC/pull/58

KurtE... thanks, I'll try that.

Note: my quick look at his PR to himself, looks like he may have the T4 and 4.1 pin defines reversed...
