Programming the ESP32 RISC V in MicroPython

Espressif's ESP32 RISC V family offers a device for every application. They are all low in cost, but each has many different subsystems that make it more powerful than you might at first think. You can use them for simple applications because they are cheap, but you can also use them for more sophisticated applications because they are capable. This book covers the C2, C3, C5, C6 and the H2, all of which are based on RISC-V architecture.

One good thing about using MicroPython on the ESP32 is that it is very easy to get started. After a simple installation procedure you have a working MicroPython machine which you can program almost at once using the Thonny IDE.

The purpose of this book is to reveal what you can do with the ESP32's GPIO lines together with widely used sensors, servos and motors and ADCs. After covering the GPIO, outputs and inputs, events and interrupts, it gives you hands-on experience of PWM (Pulse Width Modulation), the SPI bus, the I2C bus and the 1-Wire bus, the UARTs and, of course, WiFi. To round out, it covers direct access to the hardware, adding an SD Card reader, sleep states to save power, the RTC and RMT.

While not strictly a projects book, there isn't much left for you to do to finish and polish the embryonic projects that are used as examples. Instead this book is about understanding concepts and the acquisition of skills. The hope is that having read it, you will know how to tackle your own projects and get them safely to completion without wasting time in trial and error.
