Bought a SnadPIC Starter Kit that has a dsPIC33EP512MU810 installed along with USB and SD card.
The board has a demo program loaded that runs OK. Using a MicroChip HID Bootloader, I save the HEX file of the Demo program.
I have not been able to write and program a successful "Hello World" program that just turns on PORTA LED's yet.
I don't have (one on the way) a PICkit3 so I can't see what is wrong yet.
