Delve into the exciting world of embedded programming with PIC microcontrollers in C. The key to learning how to program is to understand how the code works – and that is what you’ll learn here. 

Following C Programming for the PIC Microcontroller, this book continues exploring the coding required to control the PIC microcontroller and can be used as a standalone single reference, or paired with the previous title to enhance your programming skills. You'll see how to control the position of a servo motor and use the compare aspect of the CCP module to create a square wave with varying frequency. You'll also work with the capture aspect of the CCP to determine the frequency of a signal inputted to the PIC and use external and internal interrupts.

This book breaks down the programs with line-by-line analysis to give you a deep understanding of the code. After reading it you’ll be able to use all three aspects of the Capture, Compare and PWM module; work with different types of interrupts; create useful projects with the 7 segment display; and use the LCD and push button keyboard. 

You will:

• Create a small musical keyboard with the PIC
  
• Manage a stepper motor with the PIC
• Use the main features of the MPLABX IDE
  
• Interface the PIC to the real world
• Design and create useful programs based around the PIC18F4525
