Hat top OLED not working on Raspberry pi 5 (Bookworm)

#1

I just setup my nas with the SATA Hat and the Hat Top, fan is working fine but I can’t get the OLED to display anything. Does anyone know how to get it working on RPI 5 running bookworm?

Cheers

It’s i2c OLED display, so You should see it’s address via i2cdetect utility:

$ i2cdetect -y 1
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:                         -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- 3c -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- 51 -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --

If there is nothing detected - duble check if i2c protocol is turned on, then double check connection.

Hi @Shaun_Nicholson,

Please refer to here[1] to install the software package.

I’m getting this:

pi@raspberrypi:~ $ i2cdetect -y 1
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: – -- – -- – -- – --
10: – -- – -- – -- – -- – -- – -- – -- – --
20: – -- – -- – -- – -- – -- – -- – -- – --
30: – -- – -- – -- – -- – -- – -- – -- – --
40: – -- – -- – -- – -- – -- – -- – -- – --
50: – -- – -- – -- – -- – -- – -- – -- – --
60: – -- – -- – -- – -- – -- – -- – -- – --
70: – -- – -- – -- – --

I installed the software package, checked the connections the fan is spinning just the OLED not displaying anything.

Also the fan speeds don’t seem to be controlled and when I double press the button the fan doesn’t stop spinning either.

This is the one I ordered: https://nl.rs-online.com/web/p/rock-sbc-add-ons/2565002?gb=s

Obviously i2c device is not connected, is i2c protocol enabled in raspi-config?

It is enabled, I just got a new one in the mail and this one does work. Seems like the one I had before was faulty. All sorted.

One question regarding the screen, is it possible to get the readings of omv zfs pool on there instead of the sd card?

#7

We can update the program to specify a path to the config file.

Please help. @Shawn

Is there a way to display other hdd information instead of the raspberry pi sd card?

#9

Simple python script is used to display those,
just modify it with paths and information You need: /usr/bin/rockpi-sata/misc.py
save and restart service

Do you happen to have an example code how to achieve this?

#11

It’s very simple script, try yourself to alter few lines, it’s easy to test it and make some modifications.
Probably my version will not work on Your side and I don’t remember what I changed there (my unit is out of sight now).

#12

I have no idea, so if someone has an example script by any chance I could modify it. Thanks

#13

I’ve received the topboard today, installed it, double-checked the connections, run the update Setq suggested. Nothing happens, the fan won’t come on, no leds blinking…

Hey Shaun,
I have the same problem, I also ordered from RS
https://befr.rs-online.com/web/p/rock-sbc-add-ons/2565002.
When I run the i2detect script I get 3c on the vertical 30 horizontal c line
So I should send RS an email explaining the problem, maybe I can also get a new one

#15

Hi, I ordered another one and that worked. Mine was faulty. You can probably return it to RS no problem.

If someone has an example script, would like to take a look
