'Hello World' Code For dsPIC33FJ64MC802

Here is a simple hello world code for a dsPIC33FJ64MC802.

  1. kchriste
    Here is a simple hello world code for a dsPIC33FJ64MC802. You'll have to modify the code a bit for the dsPIC33fj256; such as the config bits etc, but you can see how simple it is using the C30 compiler from MicroChip:

    Code (text):
    /* This is a "Hello world" example for the dsPIC33FJ64MC802. 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 internal RC 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. Connect a 10uF, low ESR,
    *  capacitor between VddCore (pin 20 on a 28 pin DIP chip) and ground. Do NOT
    *  connect VddCore to 3.3V! Don't forget to put some 0.1uF bypass capacitors
    *  across the power pins close to the PIC.
