I am very interested in the white jack labeled 'J2'. I've mapped where the pins go.
Code:
J2 PIC Description
1 4 RA5/MCLR/VPP
2 14 VDD
3 5 VSS
4 13 RB7/PGD/T1OSI
5 12 RB6/PGC/T1OSO/T1CKI
6 X X
Points of interest:
A) None of the possible i/o lines go to any header on the black jack. So we can assume that any IO coming from these has nothing to do with what the spec sheet we were given says.
B)Pins 2 and 3 are power.
C)Pin 1 could be input or a programming power.
D)The other used can be i/o, in circuit debugging, or programming.
I've never seen a chip flashed with such a gigantic connector (Usually there are just small contact pads, no?), and I do not think there would be need for debugging on a finished board.
So if I am correct in assuming that this jack is not meant for programing the chip, the white jack must be there to talk to something else, and will give off different signals than what the spec says so far.
Maybe we will see some kind of daughter board? Maybe this will hook up onto a field element?
