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 | |||||
