Did you read the section on PWM and Python?
The name of the package is pyPwmExp and to call it you need to use:
from OmegaExpansion import pwmExp
I think you might be reading the wrong documentation.
do you mean that GPIOX (as in python code) is controlling the GPIOX (as shown on dock)?
I mean the electrical traces seem to be identical so where the GPIO pins are listed in the 2 dock they are actually still on the 1 dock. Just the names have changed. Basically I did not have to change the dock because I could still use the same GPIO pins as if it was a 2 dock but taking into account the gotcha of using GPIO pins 1 6 7 8 and 45 as per the annotated pinout otherwise the Omega might not boot.
Handy. The hardware is built now and works fine just need to concentrate on the software.
These are interesting findings, they suggest there may be a bug in the wifi driver than can be triggered by variations in local circumstance.
Hmmm I am wondering now if that is why out of the 3 APs I have both on G and N my Omega only sees one. I tried playing around with the channels encryption cyphers etc. But to no avail.
For the record it appears that despite label differences the GPIO assignments are the same. So I am able to use GPIO 0, 14, 18, 19, 23 and 26 no problem. I can probally also use 12 & 13 as well.
This is good news for me because I had already hot-snoted my expansion dock in place and did not fancy pulling it apart again.
Edit: Of course the pins are the same the names are as the Omega 2 dock though, so 14, 23,26 becomes 46,2,3. Simple to correct and all works fine now. :) What a mess of wires though :P
So I was experimenting with my shutdown procedure and power-down and power-off are pretty useless in that regard in so much as they don't poweroff and halt the CPU but instead reboot it.
However, I have discovered if I used Linux's magic sysrq interface to send the 'Power off immediately' command. It does just that. The led goes out and the dock is dead until power is reset.
Test it yourself. Just remember that it is immediate power off so no syncing of any kind will happen. You will have to manually sync and unmount disks yourself.
echo "o" >/proc/sysrq-trigger
Still handy to have at the end of a shutdown script though.
