  Un fortunately this is not advised due to lack of space in the firmware.

  @felmue Hey felmue, I've managed to sort out my issue. It wasn't a power thing. I've been using PlatformIO to do my work as I'm trying to start using VSC for a number of tasks. I ended up going back to the Arduino IDE and surprise surprise the above code compiled and worked ok. So Iwent back and started looking at how I was trying to use the library in PlatformIO. Because the M5Tough library didn't appear in the usual library list, I had just copied the files in the GIT repo under the src folder into my VSC project src folder. It turns out that this works ok for some examples, but not the buttons one (I assuming it tries to reach a header file that it couldn't locate for these ones or something. Anyway, I found out how to add a third part library into PIO using CLI, started a new Tough project, and now the code works well. So in the end the problem was my lack of understanding (again!) but at least now I've learnt how PIO goes together. Thanks for the suggestions and your time, I sure you'll get another chance to try and help me in the future :) galeap.

  Thanks for the tip @flypeek I checked with my Hello World code and this worked. I did not expect the AtomS3 to be that different to the original AtomMatrix. However I just confirmed if I change the "board" to just M5Stack-Atom all the original code compiles. I would have expected big changes if we referred to the ESP32-C3 with the new RISC architecture, but the S3 was fairly similar I thought. I presume it has a new board definition due to the LCD screen on the AtomS3. If I can get the Zigbee unit working nicely, I might port the example over and post up a PR in the AtomS3 library. Many thanks again @flypeek you have unblocked me and I can keep moving forward (I hope).

  Hello @Hamnet correct, to continue to use M5EPD you either need to revert to Arduino 1.8 IDE (which worked for you in the past). Or you can try to comment out the lines mentioned in GT911.cpp and use Arduino IDE 2.x. The latter I tried myself and worked for me. Thanks Felix

  Try putting the Wire1.begin(...) in your program loop instead of the setup {}. assigning other pins to the I2C channel; Wire1.begin(32, 33, 100000UL); // for I2C TOF connection .. before reading the TOF, Wire1.begin(21, 22, 100000UL); // for I2C gyro connection .. before reading the gyro.

  Yes. There is nothing specific to M5Stack. Which exact model do you have? The M5Stack example will reference a library and M5.LCD. display references which may be confusing to an Arduino. Are you programming in Arduino IDE?
