Raspberry Pi Zero Cookbook

Chapter 5. Getting Your Hands Dirty Using the GPIO Header

Here, we will start diving into the more physical side of cooking with the Raspberry Pi Zero:

• Pin configurations and precautions for using the GPIO pins
• Using the GPIOs with the WiringPi library
• Connecting an LED with RPZ and controlling it using C, Python, and a shell
• Basics of the UART port and getting data from the desktop on the serial port using Minicom
• Writing a Python/C program to get UART data in your code
• Basics of I2C and checking the I2C devices present on a port
• Basics of SPI and setting up an SPI module
• Converting a 5V signal into a 3.3V signal and slew rates
• Running RPZ on a battery
• Controlling GPIOs using a web interface
• Making RPZ a radio transmitter and sharing music
• Using a Node.js ...
