OLEDproc Add-on

Is it possible to run this script using your addon?

I need to see the remaining HDD space on OLED

This is amazing! Can't wait to try it with my OLED

Hi LuRu , I am new around here and I was redirected to this thread for getting around my issue. I am running LE 2 on a Pi 5, and trying to program my OLED based on chip SSD1306. Could you please kindly share what changes should I make in order to make the add-on work in my case as well? I really appreciate your work and contribution to LE community and I thank you in advance! Cheers!

Hello,

I have a PI5 NVME 256GB ARGONE ONE V3 case

and wanted to run an OLED display on it!

The small 1.3-inch ones all work,

Now I wanted to upgrade to an SSD1363 256x128 i2c OLED display, but oledproc doesn't offer any drivers or settings.

WHAT CAN I DO

to control it?!?

THANKS in advance for the answers

Quote from LuRu

Unfortunately, I can't help much. My add-on is based on the luma.oled library. If this library doesn't contain the SSD1363 driver, then of course the OLEDproc add-on can't work with it either.
But you can try to see if it works with some other driver. Maybe the SSD1322 could use similar commands. But I don't give it much chance...

I'm sorry, but I can't really help more. First of all, I'm very busy at the moment and secondly, to be able to experiment with it, I would have to own the same display. Unfortunately, that's not the case.

Hello, thanks for answering. Thanks anyway

Thanks for the info. I already thought about the SSD1309. Since my Raspberry Pi 2, PI 3, PI 4, etc., I've been using Kodi projects as a media center, so I'm still experimenting with the displays (formerly HD44780) with the acrylic case. Thank you very much, greetings from Germany.

Hello,

SSD1309 works great.

I just ordered SSD1322.

I like it because it's wider!

Is there an entry for this in oledproc?!?

Regards

Harald

Hi, thanks for the info. It's enough for me to know that the SSD1322 is supported. THANK YOU & have a nice weekend.

Hello everybody,
I know, this thread is quite old. But I still hope to find help.

I wanted to install an OLED display for Kodi under latest libreelec on RPI3B+

The OLED is a 2.4" waveshare with SSD1309 driver.

I've started from zero. Flashed Libreelec + Kodi.
SSH access for putty.
Changed config.txt with dtparam_i2c1=on and dtaparam_i2c_arm=on

Installed the complete package with version 12.0.0.101 in the order:
script.module.cbor2

script.module.smbus2

script.module.spidev

script.module.luma

virtual.opi-tools

service.oled

But when the OLED addon seems to be installed, it shows an error message instead of starting.
Where can I check the log file for more information ?

I installed also the XMBC.LCD addon.
I could do the changes in the OLED addon (like driver chip, resolution, etc.)
I could do the changes in the XMBC addon for UTF-8 character set.

And please appologize if I ask stupid questions. I'm completely new to any raspberry programming.

Any suggestions.

Best Regards

Tobias

Hi again,

I tried to find out more details.
I'm wondering, why i2cdetect results in all adresses, instead of only one adress.

LibreELEC:~ # i2cdetect -y 1
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: 08 09 0a 0b 0c 0d 0e 0f
10: 10 11 12 13 14 15 16 17 18 19 1a 1b 1c 1d 1e 1f
20: 20 21 22 23 24 25 26 27 28 29 2a 2b 2c 2d 2e 2f
30: 30 31 32 33 34 35 36 37 38 39 3a 3b 3c 3d 3e 3f
40: 40 41 42 43 44 45 46 47 48 49 4a 4b 4c 4d 4e 4f
50: 50 51 52 53 54 55 56 57 58 59 5a 5b 5c 5d 5e 5f
60: 60 61 62 63 64 65 66 67 68 69 6a 6b 6c 6d 6e 6f
70: 70 71 72 73 74 75 76 77

Sorry, that I have to answer myself. Cannot edit the post above.

After some google, I found out the i2c behaviour seem to have any issue with a pulled down SDA signal.
Or a flipped SDA / SCLK. In case I flip, all adresses are zero. So this was not the rootcause
Unfortunately, I am now at my parents house and cannot access a scope to see the signal on Pin3.
In worst case I just got delivered a faulty OLED display by amaz*n.

In the past, I had connected a normal LCD, where at least the i2c detect worked well and served a single adress.
So I would assume, the RPI board is not the rootcause.

Maybe I give it a try with a SPI connection.

However, it doesn't explain, the issue when I try to install the OLED addon script resulting an error.

Thanks to LuRu for this addon.

Access LibreELEC via SSH to view kodi.log. To make the info easier to find, restart the OLED service first. Go to Settings > Add-ons > My add-ons > Services > Oledproc, then toggle the service off and on again.

SSH to check the log:
ssh root@libreelec
root@libreelec's password:
