Overview of this book

C++ is a great choice for embedded development, most notably, because it does not add any bloat, extends maintainability, and offers many advantages over different programming languages. Hands-On Embedded Programming with C++17 will show you how C++ can be used to build robust and concurrent systems that leverage the available hardware resources. Starting with a primer on embedded programming and the latest features of C++17, the book takes you through various facets of good programming. You’ll learn how to use the concurrency, memory management, and functional programming features of C++ to build embedded systems. You will understand how to integrate your systems with external peripherals and efficient ways of working with drivers. This book will also guide you in testing and optimizing code for better performance and implementing useful design patterns. As an additional benefit, you will see how to work with Qt, the popular GUI library used for building embedded systems. By the end of the book, you will have gained the confidence to use C++ for embedded programming.

Firmware source


In this section, we look at the source code for the ESP8266 firmware as used with the BMaC system.

Core

The core of the firmware we already looked at in Chapter 5Example - Soil Humidity Monitor with Wi-Fi, including the entry point, the OtaCore class, and the BaseModule class, which provide all of the functionality needed to make individual modules initialize and to allow them to be enabled and disabled using the MQTT interface.

 

Modules

Of the firmware modules, we already looked at the plant module inChapter 5Example - Soil Humidity Monitor with Wi-Fi. Here we will look at the remaining modules, starting with the THP module:

#include "base_module.h"
class THPModule {
    public:
    static bool initialize();
    static bool start();
    static bool shutdown();
};
#include "thp_module.h"
#include "dht_module.h"
#include "bme280_module.h"
bool THPModule::initialize() {
    BaseModule::registerModule(MOD_IDX_TEMPERATURE_HUMIDITY, 
    THPModule::start, THPModule::shutdown);...
