Best PIC Microcontrollers In Sytem Programming

PIC In System Programming - PIC microcontrollers, like most modern microcontrollers, can be programmed in system (or in circuit – ICSP) rather than in a socket programmer. 

This has advantages in development and in production, for example, to use different firmware for different versions or to speed up production. 

The major benefit though is field upgrades.PIC microcontrollers are a very useful and versatile tool for use in many electronic projects. They are very inexpensive and easy to find. They are also very powerful and many are capable of speeds up to 64 MIPS using the internal oscillator block, about 16 times faster than most comparable AVR microcontrollers. 
PICs are also easy to program, however getting the project set up can some times be tricky. These instructions will walk through the process of setting up the 
software, creating a new project, and programming some very simple functions to test the configuration and ensure everything is working. They are designed to be 
very open ended; after the project is created and the basics are finished the reader is encouraged to explore all the features and extras not covered in these 
instructions. Also you will find that these instructions will start out walking through step by step, but as the instructions near the end the reader is 
encouraged to explore other ways of accomplishing the tasks and make the project their own.
