Solved: RaspDAC OLED & Power management w/Moode 6.7.1
#1
[Updated] Post modified to capture resolution.

With huge thanks to @chano22000 for helping me through this. The ultimate problem was that I'd wired the OLED incorrectly which was interfering with the functionality of every script I was trying to apply!

I thought the PIN mapping (from the bottom) went...

   22   3
   21   2    
   20   1

..not (as it should be)

   6  5
   4  3
   2  1

Hi everyone, I wonder if I could seek your assistance regarding the excellent tutorial by rikardo1979 (here)? 

I have the RaspDAC enclosure pictured below along with the following components;
  • AUDIOPHONICS I-Sabre ES9038Q2M DAC
  • AUDIOPHONICS PI-SPC II power supply
  • Winstar WEH001602A HD44780 OLED
[Image: IMG_0622-1-1024x574.png.5e43205777f4d12d...1cad0b.png]

With the latest 6.7.1 Moode software installed and then following the instructions, I see the RaspDAC boot....and then immediately shut down. In looking at the boot log this appears to be because it sees GPIO17 = "low".

Audiophonics Shutdown script starting...
Asserting pins :
ShutDown       : GPIO17=in, Low
BootOK.        : GPIO22=out, High
ShutDown order received, Raspberry pi will no enter standby mode..

I believe I have wired the board correctly. I have double-checked the pin mappings and they appear to be correct.

The 3 wire connection for GPIO4, 17 and 22 is also appears to be correct too.

Do you have any idea what I may have done wrong?! The only thing I can think of now is that the script referenced in the tutorial isn't quite right for the PI-SPC II, or this version of Moode.

Any information grateful received!
