You'll work with Linux driver information and explore the different Raspberry Pi models, including the Pi Zero, Pi Zero W, Pi 2, Pi3 B and Pi3 B+.

"Using FreeRTOS and libopencm3 instead of the Arduino software environment, this book will help you develop multi-tasking applications that go beyond Arduino norms. In addition to the usual peripherals found in the typical Arduino device, the STM32 device includes a USB controller, RTC (Real Time Clock), DMA (Direct Memory Access controller), CAN bus and more. 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 provides the professional, student, or hobbyist a way to learn about ARM without costing an arm!"--Back cover

This book equips the reader with skills necessary to design and build custom hardware interfaces to be used by the Raspberry Pi. A thorough chapter on interfacing 5-volt systems from a 3.3-volt Raspberry Pi system equips the reader for additional peripheral options. Ready to go C++ programs involving I2C and SPI peripherals are supplies. Explores ADC, DAC, rotary encoders, and GPIO. Readers will discover low cost display and sensor options for embedded system projects. Master I2C and SPI communications from Raspbian Linux in C++. Perform ADC and DAC experiments on their Pis. Debounce hardware and software buttons/switches. Read rotary encoders for direction and step in C++. Implement flywheel rotary encoder effects for use in tuning GnuRadio. And hack GnuRadio software so it will respond to their custom hardware controls
