Custom Raspberry Pi Interfaces: Design and build hardware interfaces for the Raspberry Pi

Custom Raspberry Pi Interfaces: Design and build hardware interfaces for the Raspberry Pi

Design and build custom hardware interfaces for the Raspberry Pi and discover low cost display and sensor options for embedded system projects.

With this book you'll master 12C communications using Raspbian Linux in C++ and perform ADC and DAC experiments. You'll experiment with debounce buttons and switches using hardware and software solutions. Develop flywheel rotary encoder effects for ease of tuning and construct a hardware interface to the Music Playing Daemon (MPD) with developed software. Discover how to add your own hardware keypad for remote combination lock applications.

Custom Raspberry Pi Interfaces offers a thorough chapter on interfacing 5-volt systems to 3.3-volt Raspberry Pis designed to expand your choice of peripheral options. Ready to go C++ programs involving GPIO and I2C peripherals are provided. This book also explores ADC, DAC, rotary encoders, CMOS shift registers. I2C I/O extenders.

What you'll learn:
  • Build simple, low cost input/output interfaces including rotary encoders 
  • Interface with 5-volt devices from a 3-volt Raspberry Pi system 
  • Apply analog to digital and digital to analog conversions on the Pi 
  • Read potentiometers (volume control) from the Pi 
  • Determine step, directions, and velocity of a rotary encoder 
  • Perform remote interfacing using the I2 PCF8574 chip
  • Work with external CMOS devices like the 74HC595 (in C++)
Who this book is for:
Students and hobbyists interested in building custom interfaces for their Raspberry Pis.

VNC Connect, a brand-new version of VNC

VNC Connect, a brand-new version of VNC that allows you not only to make direct connections within your own networks, but also to make secure cloud-brokered connections back to your computer from anywhere in the world, with no specialist networking knowledge needed.

The main change in VNC Connect is the ability to connect back to your Raspberry Pi from anywhere in the world, from a wide range of devices, without any complex port forwarding or IP addressing configuration. The cloud service brokers a secure, end-to-end encrypted connection back to your Pi, letting you take control simply and securely from wherever you happen to be.



A guest post at Raspberry Pi blog, GET ‘BACK TO MY PI’ FROM ANYWHERE WITH VNC CONNECT, Andy Clark, Engineering Manager at RealVNC, introduces VNC Connect: a brand-new, and free, version of VNC that makes it simple to connect securely to your Raspberry Pi from anywhere in the world.
