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.

Air-conditioning service


To control air-conditioning units, a service much like the C&C one was developed, using the same basic template. The interesting parts of its source are the following:

#include <string>
 #include <vector>

 using namespace std;

 #include <Poco/Data/Session.h>
 #include <Poco/Data/SQLite/Connector.h>

 #include <Poco/Net/HTTPClientSession.h>
 #include <Poco/Net/HTTPSClientSession.h>

 #include <Poco/Timer.h>

 using namespace Poco;
 using namespace Poco::Net;

 class Listener;


 struct NodeInfo {
    string uid;
    float posx;
    float posy;
    float current;    
    float target;
    bool ch0_state;
    UInt8 ch0_duty;
    bool ch0_valid;
    bool ch1_state;
    UInt8 ch1_duty;
    bool ch1_valid;
    bool ch2_state;
    UInt8 ch2_duty;
    bool ch2_valid;
    bool ch3_state;
    UInt8 ch3_duty;
    bool ch3_valid;
    UInt8 validate;
 };


 struct ValveInfo {
    string uid;
    UInt8 ch0_valve;
    UInt8 ch1_valve...
