DsPic-Raspberry programmer interface

dsPic-Raspberry programmer interface

A general purpose interface consisting in two opto-couplers have been developed to program the dsPic micro-controllers directly from the Raspberry, allowing remote maintenance and reprogramming of each de-localized unit.

It as to be powered by 12 V (minimum voltage 10.5V - maximum voltage 13.5V) dsPic node unregulated Vcc and feed by the Raspberry GP_I/O, with a common digital ground.

Pin-out and connections

The following table describes the pin-out assembly of the opt-programmer developed to be used with picpgm software.

Programmer pin-out
Rasp I/O	Label	Programmer I/O	Cable
39	GND	GND	Blue/Wh
37	GPIO26	TBD - Function	Brown
35	GPIO19	TBD	Blue
33	GPIO13	TBD	Green
29	GPIO05	TBD	Brown/Wh
03	GPIO02	TBD	Orange
