See how using FreeRTOS and libopencm3 instead of the Arduino software environment will help you develop multi-tasking applications that go beyond Arduino norms. This updated version includes expanded coverage of software setup for Windows 10 and 11, additional TM32 hardware capabilities, including clear explanations of "totem pole outputs" versus "open drain outputs," and a new section on project showcasing an interrupt-driven approach for processing USART data.Each chapter contains clear explanations of the STM32 hardware capabilities to help get you started with the device, including GPIO and several other ST Microelectronics peripherals like USB and CAN bus controller. You’ll learn how to download and set up the libopencm3 + FreeRTOS development environment, using GCC. With everything set up, you’ll leverage FreeRTOS to create tasks, queues, and mutexes. You’ll also learn to work with the I2C bus to add GPIO using the PCF8574 chip. And how to create PWM output for RC control using hardware timers.You'll be introduced to new concepts that are necessary to master the STM32, such as how to extend code with GCC overlays using an external Winbond ​W25Q32 flash chip. Your knowledge is tested at the end of each chapter with exercises. Upon completing this book, you’ll be ready to work with any of the devices in the STM32 family. Beginning STM32, Second Edition provides the professional, student, or hobbyist a way to learn about ARM without costing an arm!What You'll Learn Initialize and use the libopencm3 drivers and handle interruptsUse DMA to drive a SPI based OLED displaying an analog meterRead PWM from an RC control using hardware timersUnderstand STM32 capabilities, including USB controller, RTC, DMA, CAN bus, and more Who This Book Is ForExperienced embedded engineers, students, hobbyists and makers wishing to explore the ARM architecture, going beyond Arduino limits.

Need some inspiration for your Raspberry Pi projects? Wondering how to work with Wii nunchucks, stepper motors, how to create a remote control panel? If you need guidance, Experimenting with Raspberry Pi is your own personal idea generator. Experimenting with Raspberry Pi covers how to work with various components and hardware like humidity and temperature sensors, Wii nunchucks, GPIO extenders, and IR receivers so you can add these to your own projects.Written with budgets in mind, author Warren Gay encourages you to build, experiment, and swap out various parts to learn more about the Pi and come up with the best ideas and instructions for your own amazing Raspberry Pi project ideas.

Raspberry Pi is Linux, but it's a unique flavor of Linux, specifically for the ARM-based Pi.

The Raspberry Pi is deceptively simple. Plug it in, boot it up, and use it as a personal computer, or attach a million gizmos and modules and invent something new and amazing. Either way, what it can actually do is not simple, and you should know exactly what the Raspberry Pi hardware is all about. Raspberry Pi Hardware Reference, from Mastering the Raspberry Pi, is the hardware guide you need on your desk or workbench. Every detail is covered: from power to memory, from the CPU to working with USB. You'll find all the details about working with both wired and wireless Ethernet, SD cards, and the UART interface. The GPIO chapter is invaluable, covering power budgeting, access, and even small but important details like the correct usage of sudo when working with GPIO pins. You'll also find details about the 1-Wire driver, the I2C bus, and the SPI bus. If you need to know anything about your Raspberry Pi's hardware, you will find it here, in Raspberry Pi Hardware Reference.

You have a Pi 2, but what exactly can you do with it? This book takes you on a tour of the Pi 2 hardware and all of the fantastic things that you can do to create innovative and useful projects with your Pi. Start with creating a workstation that does actual work, and move into installing a custom kernel, creating a clock, learning the ins and outs of the GPIO interface, and pick up some useful C++ skills along the way.Warren Gay, author of Mastering the Raspberry Pi, takes you through a set of experiments to show just what the Pi 2 is capable of and how you can use it to make your own fantastic creations.What You Will Learn:How to create an experimenter's workstation for the Pi 2, complete with breadboard and even ArduinoAll the details of GPIO, including a custom command for working with itUseful projects like a general purpose clock and the PiSpyQuick intro to C++ for the PiHow to make a multi-core webserverWho this book is for:Intermediate electronics enthusiasts and Pi fans, makers, students, teachers, and everyone who wants to know how to make the Pi really work.
