Using RPI_V2_P5_*
Using RPI_V2_P5_*
What are the pins labeled RPI_V2_P5_03 - RPI_V2_P5_06 in the hardware ID list? I had thought that maybe RPI_V2_P5_03 and RPI_V2_P5_05 corresponded to GPIO pins 3 and 5, but that doesn't seem to be true. What pins do these hardware IDs correspond to?
Re: Using RPI_V2_P5_*
Those are the pin numbers from the P5 header. Not all Pi's have the P5 header.

Re: Using RPI_V2_P5_*
Hello Ralph, I don't currently have a Rasp on hand,
but it seems there's a mismatch in the pin number assignment

I don't know the diagram which should be updated to match pin assignment

Re: Using RPI_V2_P5_*
The pin numbers on the wiki correspond to this image, I don't see a mismatch
P5_03 corresponds to pin number 3. The same counts for example for RPI_V2_P1_07, which corresponds to pin 7 on the main header. It is not the GPIO number you should be looking at.

Re: Using RPI_V2_P5_*
You're right Ralph, it seems I had a lot of distraction on my own
and indeed made a confusion between GPIO and Pins numbers
Thanks to clarify

Re: Using RPI_V2_P5_*
Thanks for the explanation! It looks like the Pi 3 doesn't have P5, which is a bit frustrating.
I suppose this means pins 3 and 5 on P1 are completely unavailable. Back to soldering iron!
As a side note, all of this would be massively easier if the hardware ID list page on the wiki had actual images of boards with the pins labeled.

There is quite a bit of info in the wiki here.

I still make the mistake sometimes. It can be confusing.SimPassion wrote: ↑Mon Sep 10, 2018 10:27 pm You're right Ralph, it seems I had a lot of distraction on my own

Pin 3 and 5, from memory, are I2C pins which we use ourselves for some projects.

It might be beneficial to update the pin-out in the wiki to show the i2c connections.

Re: Using RPI_V2_P5_*
The I2C connection is not available for users, only for Sim Innovations. That's why we don't display it.
