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.

Detecting Wi-Fi networks with an M5Stack scanner – part 1

You have seen that the M5Stack Core has a Wi-Fi subsystem consisting of a baseband and MAC electronic circuits. To aid these hardware elements, the software allows the configuration of these circuits with the ESP32 microcontroller core subsystem. The M5Stack Core will allow us to assess a home Wi-Fi network displayed on a 2-inch TFT LCD. The application detection code will help the M5Stack Core cohesively stitch the Wi-Fi circuits to the ESP32 core subsystem. This is all achieved using the Wi-Fi scan code found within the Arduino IDE examples. You will use the M5Stack Core example WiFiScan code to assess and display the wireless networks within your home. To access the C++code, select File | Examples | M5Stack | Advanced | WiFi | WiFiScan with your mouse. Figure 8.15 shows the selection sequence for obtaining the WiFiScan code:
