DsPIC30F4011 Development Board flashing LED example

In this article we look at the A look at a DsPIC30F4011 Development Board and we will do a hello world type example where we simply flash the LEDs on the board

Lets look at the dsPic and the LED’s on the schematic. You can see that these are all connected to the RE port

Hardware

The board costs about $25

Code

This is the main code example, the complete project will be posted below

Upload this to your development board, I connected my Pickit4 to the ICSP connection – its a 1 to 1 connection and you should see the LEDs flash in sequence – they are actually counting up

You can see the ICSP and LEDs highlighted below on the development board

Here is a bonus, this would simply flash all the leds off and then on
