'Hello World' Code For dsPIC30F2020 2012-01-07

/* This is a "Hello world" example for the dsPIC30F2020. It will toggle all
*  IO pins on the chip at a rate which is visible from a LED connected to
*  one of the IO pins. It uses the slow internal oscillator so all that is 
*  needed is a 10K pullup resistor on MCLR (pin 1 on a 28 pin DIP chip) and
*  power connected to ALL Vdd, Vss, AVdd, and AVss pins. Don't forget to
*  put some 0.1uF bypass capacitors across the power pins close to the PIC.
