Beginning Stm32: Developing with Freertos, Libopencm3, and Gcc

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!

- 使用硬體定時器從RC控制讀取PWM
- 了解STM32的功能，包括USB控制器、RTC、DMA、CAN總線等

本書適合對嵌入式工程師、學生、愛好者和製造商有經驗的人，希望探索ARM架構，超越Arduino的限制。

Warren Gay ​has been an electronics enthusiast since childhood and often dragged discarded TV sets home after school. In high school he learned to program the IBM-1130 and then pursued a career in software development at Ryerson Polytechnical, in Toronto. Since then he has worked professionally for over 30 years, mainly in C/C++, under Unix and Linux. Meanwhile, the love of electronics has never faded since the early creation of his home-brewed Intel 8008 system in the 70's to the present day projects employing the Raspberry Pi. Warren also holds an advanced amateur radio license and was able to work the Mir space station (U2MIR) using packet radio in August 1991. He's authored other books including Sams Teach Yourself Linux in 24 Hours, Linux Socket Programming by Example, and Advanced Unix Programming.

Warren Gay自小就是一位電子愛好者，放學後常常拖回家報廢的電視機。在高中時，他學會了IBM-1130的程式設計，並在多倫多的Ryerson Polytechnical追求了一個軟體開發的職業生涯。從那時起，他已經在專業領域工作了30多年，主要使用C/C++在Unix和Linux下進行開發。與此同時，他對電子的熱愛從70年代自製Intel 8008系統開始一直持續到現在，並使用Raspberry Pi進行各種項目。Warren還擁有高級業餘無線電執照，並在1991年8月使用封包無線電與Mir太空站（U2MIR）進行通訊。他還撰寫了其他書籍，包括《Sams Teach Yourself Linux in 24 Hours》、《Linux Socket Programming by Example》和《Advanced Unix Programming》。
