I solved like that: with M5Burner flash a different firmware in the stack like uiflow and than flash again lovian firmware.. tnks

if the battery already fully. the M5.Power.isCharging() function will return the ture.

@gregfordyce here is the arduino api docs link: https://docs.m5stack.com/#/en/arduino/arduino_api

Getting same error on all my projects now, I think someting is broken.

@PierreD You can run the VisualStudio Code platformIO. It supports the M5Stack ESP32. I have copied the M5_Stack_WiFi_Scanner demo arduino ino file into the platform io editor. I downloaded the code to my M5Stack (black) and it worked. Please play attention: In contrast to the arduino environement the VisualStudio Code PlatformIO is a one pass compiler, so you must place all subroutines (eg void Show(), Search()) at the beginning of your program (loop, setup ...) before they are called. You can watch a PlatformIO tutorial for Arduino, ESP8266, and ESP32 made by Andreas Spiess on YouTube : https://www.youtube.com/watch?v=0poh_2rBq7E Good luck crami25

@hansim in the this lib file , you can find the str width return function: https://github.com/m5stack/M5Stack/blob/master/src/utility/In_eSPI.h int16_t textWidth(const char *string, uint8_t font), textWidth(const char *string), textWidth(const String& string, uint8_t font), textWidth(const String& string), fontHeight(int16_t font), fontHeight(void);

@daavery You can try more times on win7, maybe just baud rate issue or USB COM / cable issue.

Hi， you should selcet M5StickC board in ther board manager. or seting the baud rate to 115200

Yes, correct I used the " M5.Lcd.setTextColor (YELLOW, BLACK);" in the setup command , and effectively overwriting by deleting the above. Thank you. Greetings.

@world101 Thanks! I'll have a look. MQTT seems to be working well for now, super easy to setup as well.

@ecasti said in I2C_Keyboard_Interrupt sample is not working.: According to several forum, Wire library require interrupt itself while any further interrupt is disabled during ISR call , so this example cannot work . Only way to make working should be moving outside wire.read() function inside a proper function registered on Wire.onReceive call ( that i'm pretty sure get called from a proper interrupt ). will make some test Hopefully, you will find the solution. Honestly, I have no time to dig further. Good luck.

@andreaf said in How to change LCD print text on runtime without creating another line: M5.Lcd.print("some text") M5.Lcd.setCursor(xposition , yposition); M5.Lcd.print("some text") or ; M5.Lcd.drawString("some text"), xposition , yposition , txtsize);

Below are examples of M5StickC and IR. https://qiita.com/poruruba/items/34220a4dd6aaf48392aa https://lang-ship.com/blog/?p=886 https://lab.sasapea.mydns.jp/2019/06/28/m5stickc-ir/ https://note.com/ssktkr/n/ne9f289509bea
