  @steve1 yes the delay is normal as it takes time for the image request to be sent to the host and the host to send the image to the paper. This happens when requesting images from all devices in the M5 range

  Thanks @teastain for the hint with USB CDC on Boot! I forgot to mention that I am on PlatformIO but the snippet shown below added to the platform.ini file helped me to solve the problem. Previously I didn't had to specify any build_flags to see the Serial output, so maybe this is a change introduced by PlatformIO. monitor_speed = 115200 build_flags = -D ARDUINO_USB_MODE=1 -D ARDUINO_USB_CDC_ON_BOOT=1 Best Marc

  I am just starting out with the M5Paper and a lot of things are taking some getting use to. I thought about deleting this thread when I found out how easy the solution was but then I thought that maybe this will help someone else. So here is the solution: You have to declare a font for use in the canvasOP. So adding his line after creating canvasOP fixes the problem: canvasOP.setFreeFont(&FreeSerif24pt7b);

  Hello @Steve1 looks like that issue isn't new. See here. Maybe try to contact the owner of the code? Thanks Felix

  @hallinen Yes, I saw your comment over on https://github.com/m5stack/M5AtomS3/issues/23 The solution to my identical issue/14 was to burn-back (erase all) to 'Arduino15/staging/packages' and re-install the M5 latest board definition. Tinyu-Zhao's solution was: "Perhaps there is a local cache package that is not downloading the latest M5Stack version definition Please delete the following path, uninstall the M5Stack 2.0.6 definition and try again /Users//Library/Arduino15/staging/packages"

  I have found out how to use the fonts within the M5GFX library; #include <Arduino.h> #include <M5GFX.h> M5GFX display; void setup() { display.begin(); display.setTextDatum(middle_center); uint16_t x = display.width() / 2; uint16_t y = display.height() / 2; display.setFont(&fonts::FreeMonoBold24pt7b); display.drawString("Test", x, y); } void loop() { }

  SOLVED: I found the upload speed setting, and sure enough, that fixed it. Thanks!

  Hmm, I get that. And appreciate that some of what we are doing here is frontier work, but when breaking changes result in the most obscure error messages know to man it's still a bit painful. The catch to response to repair time is perhaps something the community could work on, with and without GitHub. I'll cheer up after a nights sleep. I've still no idea on a fix for the fault posted. Likewise, I have had to swap from M5Core2 to M5Unified for an error earlier this am, so any other thoughts gratefully received. Update: same Arduino v2.2.1 --> PC fine, macOS the above error [groan], again.

  I found a solution. An example you can find at https://www.waveshare.com/wiki/BMM150_3-Axis_Magnetometer_Sensor (the one linked from Example Demo) with a proper modification worked with BMM150 in Env II Hat. Here is the procedure. Download the zip file from the Example Demo link. Open bmm150_Arduino.ino under Arduino > bmm150_Arduino Search Wire.begin() in the code (you can find one in the line 149) Change it to Wire.begin(0, 26) This is necessary if you are using a Hat version of ENV II HAT, which is connected to the GPIO pin side of the M5Stick variants. If you are using ENV II Hat connected the Grove port, you don't need to change it. After this modification, the code should work.

  Add line sht30.init(); straight after Wire.begin(26, 32); // Pins 19, 22 if using Atom-Mate and hats. For the StickC and ENVII hat example it needs the following change as well. SHT3X sht30; // Changed from SHT3X sht30(0x44, 1) Swap the StickC library out for Atom and comment out the LCD lines, it works perfectly as well with the Atom-Lite/Atom-Matrix. Two lines above need changed in the examples.
