Programming The ESP32 In C Using The Espressif IDF

The Espressif ESP32 is a remarkable device. It is low cost but with many different subsystems that make it more powerful than you might think. You can use it for simple applications because it is cheap, but you can also use it for more sophisticated applications because it is capable. C is the ideal choice of language to program the ESP32, ensuring that your programs are fast and efficient, and here it is used with the Espressif IoT Development Framework, ESP-IDF and VS Code, a combination which makes it simple to get started and provides a wealth of functions not found elsewhere. 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), PWM for Motor control, the SPI bus, the I2C bus and the 1-Wire bus, the UARTs and of course WiFi. To round out, it covers direct
