Richard Johnson - Programming and Prototyping with Teensy Microcontrollers

"Programming and Prototyping with Teensy Microcontrollers"

"Programming and Prototyping with Teensy Microcontrollers" is a comprehensive and expertly crafted guide for engineers, developers, and advanced enthusiasts seeking to unlock the full potential of Teensy hardware. Beginning with a detailed examination of the Teensy architecture, including analysis of various hardware generations and their core features, the book provides readers with a foundational understanding that spans electrical and system-level design. From mastering the nuances of official and third-party development tools to exploring the collaborative resources of the open-source ecosystem, this book equips readers to navigate and contribute to the rapidly evolving landscape of embedded systems.

The text progresses into professional techniques for creating robust development environments, including toolchain setup across all major operating systems, scalable project organization, library management, and integration of cutting-edge practices such as continuous integration and hardware emulation. Delving deep into programming models, it articulates the trade-offs between bare-metal programming and higher abstraction layers, efficient peripheral control, precise timing, advanced data handling through DMA, and strategies for optimizing power consumption. Rich sections on peripheral integration cover serial, USB, networking, wireless, and multi-protocol design—ensuring readers are well-versed in building complex embedded and IoT systems.

Beyond hardware and software, the book addresses real-time systems, user interface development—including display, audio, and sensor integration—and the complete workflow of rapid prototyping, custom PCB design, and in-system hardware testing. Essential chapters on security, safety, and reliability engineering provide best practices for secure boot, fault detection, and compliance. A series of advanced case studies ties these elements together, demonstrating how to create high-performance applications in robotics, audio, data acquisition, wireless sensing, and edge AI—all powered by the versatile Teensy platform.
