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

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
