Beginning C for Arduino is written for those who have no prior experience with microcontrollers or programming but would like to experiment and learn both. This book introduces you to the C programming language, reinforcing each programming structure with a simple demonstration of how you can use C to control the Arduino family of microcontrollers. Author Jack Purdum uses an engaging style to teach good programming techniques using examples that have been honed during his 25 years of university teaching.   

Beginning C for Arduino will teach you:  

  • The C programming language
  • How to use C to control a microcontroller and related hardware
  • How to extend C by creating your own library routines

During the course of the book, you will learn the basics of programming, such as working with data types, making decisions, and writing control loops. You'll then progress onto some of the trickier aspects of C programming, such as using pointers effectively, working with the C preprocessor, and tackling file I/O. Each chapter ends with a series of exercises and review questions to test your knowledge and reinforce what you have learned.

(long) val; If nothing else, this documents that you really did want to force the data of an int into a long. The Arduino compiler doesn’t complain about either noisy or silent casts, which is a bug for the “noisy” cast. To be on the safe side, always use the cast operator when performing an assignment expression involving two different data types. It will save you time in the long run and your instructor will be impressed that you truly understand what is going on with such expressions.

within the statements of the loop body that changes the state of whatever variable controls the while loop. In our example, the statement k++ becomes expression3. You should be able to convince yourself that the example while loop presented above is functionally equivalent to the code depicted in Figure 5-1 using the for loop structure. The only real difference between for and while loops is that the syntax structure of a while loop is a little less “in-your-face” about the expressions

Serial.println(initFlag); #endif for (i = 0; i < MAXPEOPLE; i++) { WriteOneRecord(i); } } Next, the code defines a constant integer named MAXPEOPLE that is used to set the limit for the number of companies you will allow. You could use a #define instead, but this gives you an actual variable to work with if you wish. That is followed by a structure declaration for servicePeople and a union with a union tag of servicePeopleUnion. Although we don’t really make much use of this union, it will

found in various header files. Also, you learned how to use the bitwise operators. Understanding how bitwise operators work is often needed when communicating with external devices over some form of data link. Exercises Write a preprocessor directive that sets pin 14 to OUTPUT if the development system is using Windows to host the compiler or to INPUT under any other host system. Suppose you have written some macro that you want to include in your program. They are currently stored in a

an arithmetic expression? Pointer arithmetic only makes sense when the pointers point to the same object. If you define a pointer to a function, what is the rvalue of a properly initialized pointer to function? Just like any other pointer variable, it must hold an lvalue. In this case, it is the lvalue of where the function resides in memory. What is the purpose of the Right-Left Rule? The purpose of the Right-Left Rule is to allow you to decipher complex data definitions. Unwind and
