Introductory Programs with the 32-bit PIC Microcontroller: A Line-by-Line Code Analysis and Reference Guide for Embedded Programming in C

Appendix

In this appendix, I will analyze some of the more common aspects of C programming and how they apply to PIC microcontrollers. I will also cover some useful concepts that will help in the understanding of how microcontrollers work, such as operators, number systems, and keywords.

Data Types and Memory

To help understand the different data types used in C, it would be helpful to appreciate their relationship to the micro’s memory. PIC micros have three areas of memory, which are

• Program memory area

• Data RAM

• Data EEPROM

The Program Memory Area

This is where all the instructions of your programs are stored.

This memory is nonvolatile, which means that when the power is removed, the information in the memory is not lost.

The Data RAM

This is where ...
