Darrel, i just looked at it, and i thought you had found it.. i stuck my meter on it and it says its correct. so i went back to the schematic and looked. its the otehr 5-pin header on the schematic that is for ISCP, the one you highlighted goes to the other board, and comes from the power supply. its the straight header on the board.
i wish you were right... then i would actually know what i did wrong...
|
Yup, should have, should have seen that.
Can you show the board layout's?
It's hard to follow past the via's.

ill see what i can do about the layout.. ive looked over it and it seems ok, but what do i know!!! i used eaglecads autoroute function so everything "should" be connected properly...
|
theres the image of the board, and i will attach the eagle file here too.
i labelled all the "important" pins. the rest go to I/Os.... and MCLR2 resistor, is a 1Mohm resistor, and its for PGM. i just didnt relabel it when i put it in there... and there was an issue with the gnd side of the caps, so i ran a jumper wire from there to the ground pin..

Probably another wrong one, but I can't tell from the picture.
Looking at some of the holes, they don't seem to be plated thru.
It could be reflections from the other side or something.

Where it would matter the most (if true) is on the +5V pin on that connector I should have been looking at the first time.
It doesn't have a good solder joint on the top layer, which is the side the trace connects to.

If the thru-hole plating is intact, it probably won't matter.

If I remember right, from the other Treadbot thread, these are homemade PCB's correct? Probably not plated thru holes unless he's got some fancy-shmancy equipment.Originally Posted by Darrel Taylor

But that's easy enough to work around.
I'm rooting for that to be the fix..........Big bucks....no whammy's......STOP!

the treadbot board was homemade... this ones not... i can get these made at Alberta Printed Circuits for less than it costs me to make them.. and these ones have thru-plating and better traces..
