Re: MK14 programming interface - MK2
Tim: If you get a moment, could you have a look at these two diagrams, attached?
The first is the Pi-MK14 programming interface V2 modified to suit the JMP PCB in the way that I believe you modified yours, by shifting some of the output lines down and crossing the top two over.
The second is the version I propose to make the 'final' JMP version. In this version, instead of swapping over the optocoupler output connections to columns 6 and 7, I have swapped over the connections to GPIO 5 (IDC 29) and GPIO 7 (IDC 26) instead. This has the same effect, but keeps the left hand side of the circuit looking a bit tidier.
