  Version 6.0 of the SiLabs VCP Driver is working perfectly in MacOS Big Sur for me now. Be sure to reboot after installing - the system driver seems to need to be properly registered via reboot. https://www.silabs.com/community/interface/forum.topic.html/vcp_driver_for_macosbigsur110x-SWJK

  Enabling firmware encryption on the ESP32, which is the microcontroller used in M5Stack devices, involves a few steps. Please note that the specifics may vary based on the development environment and tools you are using. Here are general steps you can follow using the Arduino IDE: Install the ESP32 board support: Open Arduino IDE. Go to "File" -> "Preferences." In the "Additional Boards Manager URLs" field, add the following URL: https://dl.espressif.com/dl/package_esp32_index.json Click "OK" to close the preferences dialog. Go to "Tools" -> "Board" -> "Boards Manager." Search for "esp32" and install the "esp32" package. Install the M5Stack library: Go to "Sketch" -> "Include Library" -> "Manage Libraries." Search for "M5Stack" and install the M5Stack library. Update the M5Stack library to the latest version: Open the "Library Manager" again and check if there are updates available for the M5Stack library. If yes, update to the latest version. Enable Flash Encryption in the Arduino IDE: Open your Arduino sketch. In the Arduino IDE, go to "Tools" -> "M5Stack" -> "Flash Mode" and select "QIO." *Go to "Tools" -> "M5Stack" -> "Flash Frequency" and select "40MHz." *Go to "Tools" -> "M5Stack" -> "Flash Size" and select "16MB." *Finally, go to "Tools" -> "M5Stack" -> "Partition Scheme" and select "Default 4MB with spiffs (1.2MB APP/1.5MB SPIFFS)." *Enable Flash Encryption in Code: In your Arduino sketch, add the following line at the beginning, before the setup() function: Preferences preferences; In the setup() function, add the following lines: In the setup() function, add the following lines: preferences.begin("yourAppName", false); preferences.putString("yourEncryptionKey", "your32ByteEncryptionKeyHere"); preferences.end(); // Rest of your setup code... } Replace "yourAppName" with a unique name for your application, and replace "your32ByteEncryptionKeyHere" with a 32-byte encryption key. Upload the code to your M5Stack device: Connect your M5Stack device to your computer. Select the correct port and board in the Arduino IDE. Click the "Upload" button to upload the code to your M5Stack. These steps should enable flash encryption for your M5Stack firmware. Keep in mind that once flash encryption is enabled, you need to provide the correct encryption key when uploading new firmware. Otherwise, the new firmware won't be written to the device.

  Hello, I Got the GFX font header file (by converting the Roboto.ttf file). Loaded the font file using canvas.setFreeFont(&Roboto_Medium50pt7b) and then display the text using canvas.printf(textString.c_str());. It is working fine and display the text properly but when I am giving some special characters äöü then they are not appearing on M5stack paper. Can someone please guide me what I am doing wrong? Am I missing something? Thanks The link to my question can be found here

  Good thought, that solved the problem! Atom Lite works fine at 115200. Thanks!

  @scheduledisplay Hello. Did you manage by any chance to use M5Burner to flash your own code written in Arduino?

  Update I managed to change pin map to work with Atoms3 and build new firmware. Was really easy to just remove Neopixel and add pins for LCD. Is easier than i was thinking it is... Result: import board dir(board) ['class', 'name', 'A1', 'A2', 'A4', 'A5', 'A6', 'A7', 'BTN', 'D1', 'D15', 'D16', 'D17', 'D2', 'D21', 'D33', 'D34', 'D38', 'D39', 'D5', 'D6', 'D7', 'D8', 'I2C', 'IR_LED', 'PORTA_I2C', 'PORTA_SCL', 'PORTA_SDA', 'board_id'* Got WiFi and REPL working. Now need to test all pins for function and all periferials.

  Hi, it's been a while, but meanwhile zephyr supports some M5Stack boards (e.g. Core2: https://docs.zephyrproject.org/latest/boards/xtensa/m5stack_core2/doc/index.html). In combination with LVGL this offers wide range of opportunities.

  Hi @osioli, You can upload to the core first this code (I'm using the Gray core): #include <M5Stack.h> HardwareSerial GPS(2); void setup() { GPS.begin(9600); Serial.begin(115200); } void loop() { for (;;) { if (GPS.available() > 0) Serial.write(GPS.read()); if (Serial.available() > 0) GPS.write(Serial.read()); } } In u-center set the baud rate to 115200. Go to View-Messages View (F9), expand UBX-CFG-MSG and check UART1. In my case the satellites detection only works outdoors.

  @NotInTheMafia The touchscreen uses i2C, so does the AXP192. What could be happening is an i2C bus error, due to the address of the touchscreen not being present, and no more data being sent to the AXP192, resulting in no power past that point.
