How To Develop Embedded Software

About the Book

This book uses an example project to illustrate each of the steps used to develop a new embedded system program.

System requirements and architecture are developed, followed by methods to estimate level of effort needed to implement them. A simple design methodology shows how to divide the system into cooperating virtual software objects, along with suggestions for their verification. Suggestions are made for coding, debugging, and verifying the virtual objects, as well as integrating them into a working program, and demonstrating the requirements have been met.

Complete source code, with makefile, is included with the purchase of the book. The attention paid to architecture and design make it easier to follow the example source code, or to make changes and add features as needed.

The source code in this book implements a digital trombone, which uses a slide potentiometer to control the note played, and an air pressure sensor with a tube into which the user blows to make and control notes. A spring-loaded on-off switch is used to choose between saw, square, triangle, or sine waveforms. The buffered DAC output is conveyed to an on-board, 3.5 mm audio jack.

The example program can be built with a free version of the GNU ARM compiler toolset on Windows, Linux, or Mac. The binary code produced can be copied to the NUCLEO-L432KC bed icon on the desktop. Or a Visual Studio Code program from Microsoft may be used to build, load and debug the program on the target board. Visual Studio Code build directories are included free with the purchase of the book.

I have developed embedded software for 30 years.  Along the way, I have worn out several keyboards, stared holes in multiple displays, and produced firmware for a wide variety of electronic products.

Systems developed in whole or part include: Multi-parameter biofeedback system for Apple II, C and Dsp code for a television watching robot, firmware for a laser power meter, hypertext editor and math assistant for a pocket PC, autosampler firmware for a hematology instrument, robotic control and sequencer for a genetic blood assay machine, bootloader and kernel for an oximeter, portable flight planning computer, firmware for a wireless data acquisition system for bridge diagnostics, base station firmware for corrections telemetry and alcohol monitoring, communications protocol for an implantable hearing aid, usb mass storage driver, and sensor drivers for an oilfield seismic data logger, firmware for a digital theremin and a gps locator-tracker.
