		+	available for download from Microchip’s web site at http://www.microchip.com):
		+
		+	* PIC Datasheet

		+	== '''Part 2: Basic hardware''' ==
		+
		+	Besides a PC, because of we intend "make" something and not only talk about it, we need some
		+	hardware tools:
		+
		+	* PIC programmer-debugger (in Ai&R Lab Lambrate you can find some Microchip ICD2 programmer-debugger and, some adapter boards with ZIF socket and some self-made programming cables)
		+	* PIC demoboard or your board with power supply, PIC, oscillator MCLR circuitry and some input-output hardware

		+	=== Programming Cable ===
		+
		+
		+	== '''Part 3: PIC programming''' ==
		+
		+
		+	=== MPLAB settings ===
		+
		+
		+	=== Start a new project ===
		+
		+	Then, let’s follow the “New Project Set-up” checklist to create a new project with the MPLAB IDE:
		+
		+	* Select “Project->Project Wizard” to activate the new project wizard, which will guide us
		+	automatically through the following steps…
		+	* Select the correct PIC device, and click Next.
		+	* Select the MPLAB C30 Compiler Suite and click Next.
		+	* Create a new folder and name it “FolderName”; name the project “ProjectName” and click Next.
		+
		+	Simply click Next to the following dialog box—there is no need to copy any source files from
		+	any previous projects or directories.
		+	Click on Finish to complete the Wizard set-up.
		+
		+	Open a new editor window.
		+
		+	Select “File->Save As”, to save the file as: “FileName.c”.
		+	Select “Project->Save” to save the project.
		+	Our first line of code is going to be:
		+
		+	#include <p24fj128ga010.h>
		+
		+	This is a pseudo-instruction for the preprocessor telling the compiler to read the content of a
		+	device-specifi c fi le before proceeding any further. The content of the device-specifi c “.h”
		+	file chosen is a long list of the names (and sizes) of all the internal special-function registers (SFRs) of the chosen PIC model: those names reflect exactly those being used in the device datasheet.
		+	Let’s add a couple more lines that will introduce you to the main() function:
		+
		+	main()
		+	{
		+
		+	}
		+
		+	The main() function is the place where the microcontroller (program counter) will go first at
		+	power-up or after each subsequent reset.
		+	Before entering the main() function, the microcontroller will execute a short initialization code
		+	segment automatically inserted by the linker. This is known as the c0 code. The c0 code will
		+	perform basic housekeeping chores, including the initialization of the microcontroller stack,
		+	among other things.
