M5Stack Electronic Blueprints

By: Don Wilcher

Overview of this book

As an embedded systems developer or an IoT developer, you can often face challenges in maintaining focus on prototyping a product concept while using a specific high-level programming language for implementation. To overcome these challenges, the M5Stack Core platform uses an ESP32 microcontroller and block code that allows you to focus on product creation and application instead of the high-level programming language. M5Stack Electronics Blueprints presents various design and prototyping approaches as well as UI layout and electronics interfacing techniques that will help you to become skilled in developing useful products effectively. This book takes you through a hands-on journey for a better understanding of the ESP32 microcontroller and the M5Stack Core's architecture. You’ll delve into M5Stack Core topics such as electronic units, light, sound, motion devices, interfacing circuits, SNAP circuit kits, Arduino applications, and building Bluetooth and Wi-Fi IoT devices. Further, you’ll explore various M5Stack core applications using a project-based learning method, including the fascinating 32-bit microcontroller device technology. By the end of this book, you’ll be able to design and build interactive, portable electronic controllers, IoT, and wearable devices using the M5Stack Core.

Coding an M5Stack Core RGB LED flasher

The M5Stack Core has internal RGB LEDs that can be commanded by the ESP32 microcontroller. The RGB LEDs are of the SK6812 programmable family variant. The SK6812 is a smart control circuit that operates an LED. The smart control circuit and light-emitting circuit are packaged inside one programmable LED source. You can refer to Figure 3.2 for viewing the physical package, mechanical dimensions, and electronic symbol of the SK6812 RGB component. Another added feature of the SK6812 LED is the ability to emit a natural white light. Therefore, the SK6812 is an RGBW light-emitting component.

Note

Obtaining the natural white color requires a technique in color mixing of the RGB emitters. The following website provides information on obtaining white and various colors: https://txwes.libguides.com/c.php?g=978475&p=7075536.

The M5Stack Core uses two SK6812 LED bars. The SK6812 LED bar is located on each side of the M5Stack Core. Figure 3.26...
