 The newly-produced M5Core replaces the screen with better display performance and higher viewing angle, so it has some compatibility problems with the old Arduino library. When using the old library for screen driving, it will produce reverse color display. You can open the Arduino. The library management option will upgrade your M5Stack library to the latest version (after 0.2.8) to solve this problem.

 All M5stack development board can be programmed through Arduino IDE, WebIDE UIFlow, Micropython, and Blockly, simplifying the development process for those requiring a joint hardware and software solution. Not only does M5stack have far-reaching IoT applications in industry, agriculture, and home, but it also empowers students to learn to code in STEM classrooms.

 To use AD read function : 
 1, Use Dupont cable refers to the pins on the side which can be used as an AD channel.
 2, Get a M5GO bottom, which comes with a PortB.
 3, Get a PbHUB and connect it with PortA, then you can have 6 PortBs.
