MicroPython On WebIDE: 1.Prepare and Hello World!



  • This lesson focuses on cloud service M5Stack Cloud, and programming language MicroPython. Thanks to the cloud you no longer need to use the Arduino IDE and USB cable.

    Step 1. In order to M5Stack supported the Cloud, you must download the latest firmware using the official tool Flash Download Tools for ESP32 (you can download it from our storage here (Fig. 1) or from the official website here (Fig. 1.1));

    Step 12. After the browser reports that the page is not available - in this case it is well. Note the display of the device, it shows the verification code and the address of the cloud http://io.m5stack.com (Fig. 12);

    Step 14. Add Your device to the cloud, it is necessary to click on the Add button (Fig. 14) then enter the verification code shown on the display device in the input field and click OK (Fig. 14.1). When the device is added You will see it in the menu control of the device (Fig. 14.2) and the display will show the corresponding row (Fig. 14.3);
