This book is intended to fill the need for an intermediate level overview of programming microcontrollers using the C programming language. It is aimed specifically at two groups of readers who have different, yet overlapping needs. The first group are familiar with C but require an examination of the general nature of microcontrollers: what they are, how they behave and how best to use the C language to program them. The second group are familiar with microcontrollers but are new to the C programming language and wish to use C for microcontroller development projects. First Steps with Embedded Systems will be useful both as an introduction to microcontroller programming for intermediate level post-secondary programs and as a guide for developers coping with the growth and change of the microcontroller industry.

Summary

First Steps with Embedded Systems provides an intermediate-level overview of programming microcontrollers in the C language, explaining microcontroller behavior, hardware access patterns, and practical firmware techniques. The book helps readers learn how to map C code to low-level peripherals, handle interrupts, and build reliable embedded systems through worked examples and pragmatic guidance.

Key Takeaways

Understand microcontroller architectures and how hardware features map to C constructs
Write efficient, readable C for low-level hardware access including memory-mapped I/O
Implement common communication interfaces (UART, SPI, I2C) and basic protocol handling
Apply bare-metal techniques such as interrupt-driven design and startup/boot code
Use debugging and testing strategies appropriate for embedded firmware development

Who Should Read This

An intermediate-level engineer, technician, or post-secondary student who is comfortable with either C or microcontrollers and wants to learn to program microcontrollers in C to develop and debug reliable firmware and peripheral interfaces.
