Felix; thanks for the tip in the Grove pinout; exactly where I was stuck after experimenting.
I love all computers. Always have.
I'm a retired computer programmer. My first product was a keyboard macro program (Tempo - Affinity Software, Macintosh) in the late 1980's.
Later I helped in a small way to invent email (QuickMail - CE Software, Macintosh.)
I worked for startups and shutdowns. I moved around the country. It was a blast.
I spent my last 23 years at Microsoft, where I mostly worked on Visual Studio.
I enjoy programming in many languages, on many operating systems. It's a wonderful time to be a geek.

Stamp-Pico Arduino lib?
https://docs.m5stack.com/en/arduino/arduino_development mentions the new stamp-pico, but falls short of mentioning what library/header one uses in an Arduino Stamp sketch for it.
Would it use M5Atom.h?

3 & 4. Plus PlatformIO as well.
RE: M5Sound 😎
Thanks for the
I've just glanced at the Sound stuff (very nice!) but am still working on Touch.
I wrote a test to determine what the minimal effective touch button size is (https://github.com/vkichline/ButtonSizeTest).
When I moved it from PlatformIO (for development) to Arduino (for publishing) I moved from your master branch to the M5Sound branch. The app built, but did not run in M5Sound. (It drew one button and stopped. I haven't looked into it yet.)
Are you making touch changes in M5Sound as well?
RE: Touch Buttons and Styluses
I wrote a program to see what a reasonable minimum size touch button is: https://github.com/vkichline/ButtonSizeTest
It's a test you play: it lets you choose what size button and what spacing; it makes a bunch of buttons and asks you to press eight of them. At some point you should stop getting perfect scores.
I'd be interested in hearing what people find a usable minimum to be.
Caution: to use this app, you need RopG's PR for M5Core2. You can download the touch button version of the lib here: https://github.com/ropg/M5Core2.
Touch Buttons and Styluses
Rop's latest sample (M5Sound, in this forum) make me wonder what a reasonable, minimum size and spacing should be for TouchButtons. At almost 80 X 60 pixels, the DTMF buttons are usable, but already require some care with only 12 on the screen.
I dug up an old passive capacitive stylus (the kind that looks like a soft pencil eraser) and found it increases speed and accuracy. Maybe a 50 X 50 pixel button would be usable with the passive stylus (doubling the number of buttons available.)
I see that there are active capacitive styluses available with much smaller tips. Does anyone have one? Does it work well with the Core2?
