That's great news. Yes, I have a 1322-SPI in my DAC - that was the one this all started with :-) . It works perfectly for me. One nice thing is that it support greyscale

device_params={"rotate":0, "mode":"RGB"}

, so I have some options in different shades of grey, which...

[psketch]

Hi Gunter. Glad to hear that - I was scratching my head. So, the SPI display now works without any blanking? Did you manage to track down the cause, and might the same problem have been affecting the I2C?

Torsten, Gunter discovered we needed some modprobes added, so that may fix the...

I've not tried Moode, so can't comment on that, but if you want to push pcp & squeezelite's sound quality to the max, it's worth reading soundcheck's blog...

[psketch]

Oh damn. OK, I'll change it. Thanks for checking - problems of not being able to test the I2C stuff myself.

Edit : OK - should be fixed in the setup now....

[psketch]

Thanks. I've added the section to the .cfg on the standard install now, and added the modprobes as well, so should work OOB now. Thanks for digging into it.

Yes, I think I agree with you, given that it works with 1106. Quick bit of searching shows that the luma.oled used to give IO Error 5 if the display was missing, so sounds like a comms problem to the display.

Just to tidy things up....

1) Before you added the modprobes, you...

[psketch]

OK. well the screen is going blank because the script is crashing, which is odd. That error (critical etc.) says the script is crashing with an underlying OS error (bad filename, permission etc.) on line 752 of oled4pcp_4.py, which is really weird because line 752 is actually blank.

Anyway,...

[psketch]

I didn't get to the setup today, but will try and get it done tomorrow, but you're already doing the same thing so let's look at the blanking...

Couple of questions... When the screen blanks, can you take a look at the pcp_boot.log via the Diagnostics page? Is there anything new in there?...

[psketch]

I'll add them into the setup later today, so hopefully that'll deal with that part of the problem and we can look at the blanking...

[psketch]

I'd guess that's a permissions problem on /dev/i2c-1. When you did the modprobe this time, did you do it with or without sudo?...

[psketch]

Thanks Günter. That's cleared that option up. Looks like it's just the 2 modprobes required. I'll make the setup add the lines to bootlocal. For now, just add them yourself and you'll be doing the same as the install will do in the future.

Good to know what we needed for i2c - thanks...

Hi Günter

Somehow you've managed to loose the python installation from the machine. Your log shows ...

python3: not found

So, you're not getting any errors because Python's not there to try and load the script. Not sure how that's gone - perhaps when you were...

[psketch]

Not quite - smbus and smbus2 are different. smbus2 should be available by default as it's part of the package I build. I think the luma stuff might use smbus2 if it's available, but guesswork tbh as I can't test it. Would be good if you get a chance - just so I can fix things in the right way for...

[psketch]

Sorry - should have been more clear - import smbus2 is a python command to add to the start of the file /home/tc/.oled4pcp/oled4pcp_4.py. At the top of that file, you'll see

import sys
import importlib
importlib.reload(sys)
import os
import time

Hi Gunter

Thanks for digging into this. I'll make some changes to the setup to make the necessary changes, but as I mentioned, I can't test the I2C stuff. Would you be willing to try a couple of things .... Firstly, it looks like it's modprobe i2c-dev that's required - would you be able...

[psketch]

Hi

No, you shouldn't need to install anything else, but I haven't been able to test I2C as I don't have one myself. If you look at Main Page/Diagnostics/Logs, is there anything showing in the pcp_boot.log.

The command line is taken from the cfg - so the overall device setup...

[psketch]

Actually - just added a 5th step to the list....

[psketch]

Yes, normally when someone says "nothing can wrong", I'd panic, but in this case, setting up from scratch only takes a few minutes anyway these days. Longest wait is expanding the file system it seems......

[psketch]

Hi Torsten

So, I think you'll just want to run the new installer, but first remove some of the old bits.. I would

1. Edit the file /mnt/mmcblk0p2/tce/onboot.lst and remove the entry for oled4pcp_4-py38-64-deps.tcz or oled4pcp_4-py38-deps.tcz
2. Reboot and then remove that file from /mnt/mmcblk0p2/tce/optional
3. Clear
