Beginning STM32: Developing with FreeRTOS, libopencm3 and GCC (1 ed)

Beginning STM32: Developing with FreeRTOS, libopencm3 and GCC (1 ed)

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 clearly explains 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. Using GCC, you’ll learn how to download and set up the libopencm3 and FreeRTOS development environments. 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.
Beginning STM32 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, 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.
