This textbook introduces basic and advanced embedded system topics through Arm Cortex M microcontrollers, covering programmable microcontroller usage starting from basic to advanced concepts using the STMicroelectronics Discovery development board. Designed for use in upper-level undergraduate and graduate courses on microcontrollers, microprocessor systems, and embedded systems, the book explores fundamental and advanced topics, real-time operating systems via FreeRTOS and Mbed OS, and then offers a solid grounding in digital signal processing, digital control, and digital image processing concepts — with emphasis placed on the usage of a microcontroller for these advanced topics. The book uses C language, “the” programming language for microcontrollers, C++ language, and MicroPython, which allows Python language usage on a microcontroller. Sample codes and course slides are available for readers and instructors, and a solutions manual is available to instructors. The book will also be an ideal reference for practicing engineers and electronics hobbyists who wish to become familiar with basic and advanced microcontroller concepts.

Go All the Way to the Top: Amateur Extra Class! The ARRL Extra Class License Manual for Ham Radio is your ticket to every privilege granted to amateur radio operators – all frequencies, operating modes, and power levels. It has all the questions and answers, with detailed explanations, for examinations taken between July 1, 2020 and June 30, 2024. To upgrade to Amateur Extra, you must already hold a General class license (or have recently passed all of the exams required for a General license). You are holding the key to your final step up the amateur radio license ladder! With full access to the entire amateur radio frequency spectrum, you will be permitted to operate using every privilege granted to amateurs by the Federal Communications Commission.
