Usage

Installing the USB Driver

  • Download the SiLabs CP2104 Driver but do NOT use the Windows 10 Universal (v10.1.1) driver! If you happen to download the Universal version, you may need to manually revert to 6.7.1 on a regular basis as Windows will repeatedly use the newer, incorrect driver after each Windows update.

(Note: If you cannot upload, please try the legacy v4 driver below. You will need to uninstall the v5 driver. And try to use a lower baudrate: 115200)

Installing the ESP32 Arduino Core

Download Library

Using the Arduino IDE Library Manager

  1. Choose Sketch -> Include Library -> Manage Libraries...
  2. Type m5stack into the search box.
  3. Click the row to select the library.
  4. Click the Install button to install the library.
  5. Click "File-> Examples". Here are some test programs in "M5Stack->"

Using Git (most environments)
