Beginning STM32: Developing with FreeRTOS, libopencm3 and GCC (2 ed)

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 STM32 hardware capabilities, including clear explanations of “totem pole outputs” versus “open drain outputs,” and a new section on the 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 controllers. You’ll learn how to download and set up the libopencm3 and FreeRTOS development environments 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. Learn how to utilize hardware timers to generate PWM output for RC control.

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. After finishing this book, you'll be ready to work with any of the devices in the STM32 family. 
Second Edition, beginning with STM32, provides a way for professionals, students, and hobbyists to learn about ARM without spending an arm!

What you'll learn

• Initialize and use the libopencm3 drivers, as well as handle interrupts.
• Use DMA to drive an SPI-based OLED displaying an analog meter.
  
• Hardware timers can be used to read PWM from an RC control.
• Understand STM32 capabilities, including USB controller, RTC, DMA, and CAN bus.

This book is for experienced embedded engineers, students, hobbyists, and makers who wish to explore ARM architecture and go beyond Arduino's limits.
