Hi
Just found the manual on my system, it does not give the schematic as 1 diagram, it shows the individual sections.
I have attached it.
Hi,
Thanks for that, I was looking for a complete diagram and originally disregarded the individual sections.
The key thing is how are the three programming lines set up. Mclre, RB7/PGD and RB6/PGC - well they are fine.
Looks like you can simply remove the 877, connect a cable to the 40 pin link socket and build up your own circuit board, using all the ancillary devices on the Proton board.
Dont forget , just to prove it works, you can build the circuit on the breadboard.
An old PC IDC cable should fit if you have some kicking around - but whatever you use keep the distance between the boards as short as possible.
I have found a total wire length more that 12" from the Pickit2 can lead to programming failure.
Two things to bear in mind, The two programing lines PGC and PCD + Mclre should be kept clear of anything other than switches in your working circuit so you can program them instantly.
On smaller chips you may want to use those pins for some active devices, in which case you will have to fit a DP switch to isolate them while programming.
Similary to run the hardware debugger from mpab via the Pk2/3 you must have those 3 lines clear, but be aware that not all chips, particulary the smaller ones have the Debugger feature.
Its not an essintial tool but it can be easier/interesting to monitor your program /circuit.
