Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

NO

Pin(1) is pin 6 on the IDC Connector

Or to say it in my preferred language

I/O Channel 1 is on IDC pin 6

Remember to ignore the pin numbering on the right angle IDC connector, it is wrong.

go from the circuit diagram.

The picture in the user manual is of the backwards right angle connector.

Alternately, look at the pin-holes in the cable connector [ie cable pointing away from you, connector facing you].
Then the diagram is correct.

If the Silicon Chip schematic (fig.1) on page 33 of the March 2011 edition is correct then I would would go so far as to say PIC32 pin 12 is I/O 1 connected to IDC 6 and which is labeled as pin 1 on the IDC drawing when looking at the back of the Maximite

Has anyone found any problems with this drawing (unlike the discussion elsewhere on the forum which is a tad confusing) on the IDC pinout drawing which is supposed to have errors.

I can't see any problems except that it doesn't conform to a standard.

Yeah, the 3.3 & 5 v pins are reversed on that diagram.

Don't use the Silicon Chip diagram, go to Geoff's Maximite page and use that one. The SC diagram has quite a few errors...

For crying out loud, all I wanted to do was flash this blasted LED.
