AUDIOPHONICS RASPDAC MINI Kit

[kit1cat]

I got the Audiophonics python OLED script working with on pCP 6.1 with python3.6
(A quick and dirty port of an old Audiophonics python script is attached.)

Increase your filesystem size (500 MB is more than enough)

Install the following extensions: compiletc.tcz, freetype-dev.tcz, python3.6-dev.tcz, squashfs-tools.tcz (I may have forgotten one or two)

Create a file called reqs.pip with the following contents:

pillow --global-option="build_ext" --global-option="--disable-jpeg" --global-option="--disable-zlib" --global-option="--enable-freetype"
luma.oled
luma.core
pyftdi
smbus2
spidev
RPI.GPIO
pyusb
pyserial
pylms

Then run the following commands

sudo python3 -m pip install --upgrade pip setuptools
pip install -r reqs.pip --prefix=/tmp/raspdacmini-deps/usr/local --ignore-installed
sed -i 's/\t/        /' /tmp/raspdacmini-deps/usr/local/lib/python3.6/site-packages/pylms/player.py
mksquashfs /tmp/raspdacmini-deps /tmp/raspdacmini-py36-deps.tcz
sudo cp -p /tmp/raspdacmini-py36-deps.tcz /etc/sysconfig/tcedir/optional
echo raspdacmini-py36-deps.tcz | sudo tee -a /etc/sysconfig/tcedir/onboot.lst

Tried installing a couple of times today but no luck, seems to install ok but no display.

On reboot the reqs.pip file is empty, is this normal?

Is the lms_oled_1.54_spi_audiophonics_py3.py file just for info or do I need to run it some how?

Thanks

reqs.pip won't survive a reboot unless you do a backup, but you only need that file if you are building the python dependencies.

Sorry, I should have been clear -- run this to start the display:

python3 lms_oled_1.54_spi_audiophonics_py3.py

If it works and you like it, add that line to "User Commands" on the Tweaks page to start it on reboot.
If you get errors, post here.

Thanks, sorry to be a pain, but is there a way to copy the python3 lms_oled_1.54_spi_audiophonics_py3.py file from windows to the sd card? I normally use Linux file system for windows by Paragon Software but I don't think that will work with picoreplayer.

WinSCP (works alongside Putty) is a good way to move files between pCP and Windows.

[shunte88]

Microsoft got their act together and full embraced the Linux world with WSL 2

https://docs.microsoft.com/en-us/windows/wsl/install-win10

No more dual booting, or Docker
You can spin up a linux environment in seconds along with all the tools and productivity enhancements you'd ever need

Under windows 10 has full linux integration inclusive of ssh and scp so use of WinSCP, Filezilla or putty is pretty much moot

I only use a Windows machine at home for my Photoshop setup but now I have no excuse not to spin up a Linux instance on the same machine and get the best of both worlds.

From reading earlier in the thread, I thought you already had the OLED directory from the dietpi image, which contains the required fonts.
I am having trouble attaching it in a zipfile here (no useful error message), but it is the same fonts subdirectory as in the 7z file in this post

You'll also need to edit lms_oled_1.54_spi_audiophonics_py3.py line 75 and 79 to contain your server IP and player MAC address. (As mentioned here https://forums.slimdevices.com/showt...284#post976284)

Thanks for further info guys, I will take a look.

Sorry gregex, I did not realise I needed other files to get your solution up and running. I thought running your script would be enough, like the script I ran for moOde. Unfortunately I am not a Linux user, I can cut/paste commands and edit a simple file but that's about it. I still have the dietpi image but there was no info on how get up and running with picoreplayer. Any way, thanks again for your help. I will give it another go later.

@Paul-Webster - WinSCP looks like just what I needed.

@shunte88 - WSL 2 looks a great way of learning a bit of Linux.

Thanks guys

I have found WinSCP very useful for looking at the files on the SD card , but when I try to copy or edit a file I keep getting error 3 Permission denied, works without a problem on my dietpi image. Any way around this error?

When I booted my dietpi image, I found the display was working ok, which I find a bit strange. It was not working last time I tried it?

Select SCP
Host name
Port Number
User Name
Password
Click on Advanced
Click on SCP/Shell
From the Default dropdown select sudo/su
OK

if you are going to open this a lot you can save the link

piCoreplayer doesn't need this procedure (I think, from memory)

Thanks ronnie, but not working for me, I wonder if I am using a different version?

I only have shell and no sudo/su option only sudo su - ?

I use "sudo -s" in winSCP if I require root access.

[gregex]

Not sure why root access should be required to scp files to piCorePlayer. User should be tc and files should be written by default to /home/tc. Using "pi" or "dietpi" will give Permission Denied (I do this accidentally all the time when switching between boot images)

[kit1cat]

Partial Success Copied the font folder and the oled_1.54_spi_audiophonics_py3.py file to /home/tc, ran the command python3 lms_oled_1.54_spi_audiophonics_py3.py from puttty and I have a display reading "Trying to connect player to LMS". My LMS server is on another PI connected to a usb drive.
