      Hi, I wanted to know if there is a way to use faces keyboard in the menus (i.e. I have the calculator keyboard and instead of using the three buttons to go up and down and select, I want to use the keys on the face, for example for selecting first line I will type on the key '1' and so on). and if it is possible, can you give me an example of code using it. Thanks

      @gachapo Thanks for persevering with this as I got my M5 to day and was getting confused lol. Without this link I would never have got it up and running so thanks for the link as that has kept me from throwing it out of the window.

      For anybody else looking at fixing the issue with multiple simultaneous button presses it seems it can't be done. Having dived into the M5Core2 source the events generated for two button presses, e.g. A & C, are press for A and move for A. This looked like a deeper bug (since the second should have been identified as C), so going further in I found that an else branch wasn't refreshing the currently identified touched button on second press (C) in the method "doEvents" in touch.cpp (it doesn't help the code isn't documented, isn't single responsibility and has an arrow antipattern too). Fixing that bug, so the correct button is refreshed, showed that two events together did not produce presses for A & C but instead (I assume - I'm fed up at this point) the hardware averages the presses' coordinates and declares it's button B(!) that is pressed. If you have old Core 1 code you're porting that uses two simultaneous button presses I'd suggest changing the code to double taps of a single button instead which is the workaround I'm about to use - to remain consistent this behaviour is both on Core 1 and Core 2 More formally, I should have read the file header in touch.h earlier: the M5Stack Core2 touch display is only multi-touch in one dimension. What that means is that it can detect two separate touches only if they occur on different vertical positions. This has to do with the way the touch screen is wired, it's not something that can be changed in software. So you will only ever see two points if they do not occur side-by-side. Touches that do happen side-by-side blend into one touch that is detected somewhere between the actual touches.

      I've got similar problems: Not being able to burn anything from VSCode/PlatformIO with the same error message. Running under macOS Big Sur. Trying to use the M5AtomLite I finally got it working under Arduino IDE, being able to burn code. The UIFlo software also works, partially. With the M5Burner I can erase and burn the UIFlow software, setting it to USB mode, and after that, it is able to burn a new program with UIFlow (using 1.7.2 beta). But after each burn, the connection gets lost and I need to go to M5Burner separately, erase the Atom and burn UIFlow again, and setting it to USB-mode. But my prime concern is using VSCode, which doesn't work Using Board definition pico32.

      @dpharris in the FS root path has already had main.py file you could modify it. when you select the app mode(purple) main.py will be exec. if you are use UIFlow, you need to download the program, not just exec it. then it will auto setting this program for auto-start running. if still not work, pls check the serial log

      Hello @AndyT hmm, strange, if anything I'd expected the M5Stack Gray to work with low brightness level and the M5Stack Black to not behave due to the fact that the M5Stack Gray has additional hardware (e.g. IMU) consuming power to keep the device powered on. That said, I suspect the IP5306 switching off due to too light load. Try to add the following statement before going into deep sleep. It should prevent the IP5306 from shutting down under light load. M5.Power.setPowerBoostKeepOn(true); Happy Stacking! Felix

      @world101 said in How to control lots of Neopixel: @osc, WLED (https://github.com/Aircoookie/WLED) is a really great and easy way to control lots of neopixels. The author has done an awesome job and there are so many features supported now. I used it this past Christmas season to control 800 of the WS2811 string LEDs on the exterior of my home. It runs on the ESP8266 and ESP32, but I haven’t seen anyone using an m5stack product as a controller yet. The most common platform used is the nodeMCU which is based on the ESP8266. I only started trying to port WLED to the m5stack yesterday (I was inspired by this thread), but since I’m new to PlatformIO and I’m a weak programmer, I’m running into build/compile issues. I’ll let you know if I make any progress, but you could also look into the nodeMCU if you want something running quickly. If there was a Micropython lib then i would be interested in testing.
