You probably copy\pasted it from github, it copies weird characters. Either download the file or open it in raw mode and then copy\paste.
Preferably just download it as is, and put it in place, don’t edit it.

Hello all!
I have a question.
Does OpenVFD service also control the On/Standby LEDs of the TV Box?
I have a Vontar X3 TV Box. As already suggested in the thread, I used the config from HK1 X3 and VFD itself works fine, except for the On/Standby LEDs. They are swapped (It is “Red” when CE is running and “Blue” when it is switched off).
The native Android firmware however lights it correctly: Red in standby and Blue when it is on.
Any ideas on how can I correct this behavior?
This is most likely a DTB thing, OpenVFD doesn’t control the box’s LEDs.

Is there any link where I can read more about dtb ?
I understand it’s not the best place to ask it, if you point where should I will ask there, but:
is
gpioleds {
compatible = "gpio-leds";
status = "okay";
sys_led {
label = "sys_led";
gpios = <0x45 0x0b 0x01>;
linux,default-trigger = "default-on";
};
what I am looking for?
EDIT: Solved. For anyone looking for a solution here is it
Hi,
I’m a newbie in this forum and would like to ask for help configuring the vfd.
I bought an X96 android box with S905X4 and I want to use it with CoreELEC, but I can’t get the vfd to work.
The cat /sys/kernel/debug/gpio output from Android 11: https://pastebin.com/U96SsFxm
I also found this file in the android kernel:
https://android.googlesource.com/kernel/arm64/+/f5269100977385d1fd4a5ef68e49631892cf4fe4/include/dt-bindings/gpio/meson-sc2-gpio.h
I opened the box and there is AiP1628 chip and type “3” display in it.
Based on this information I created a new vfd.conf file with the following lines:
vfd_gpio_clk=‘0,0,0x00’
vfd_gpio_dat=‘0,1,0x00’
vfd_gpio_stb=‘0,39,0x00’
vfd_chars=‘4,3,2,1,0’
vfd_dot_bits=‘0,1,2,3,4,5,6’
vfd_display_type=‘0x03,0x00,0x00,0x00’
But no luck, the display remained dark.
The box is with 4/64GB memory and 1000Mbps Ethernet port: https://imgaz.staticbg.com/thumb/large/oaupload/banggood/images/29/B9/199920bc-cd4c-464c-bf0c-18dcb97b34d0.jpg.webp
(Sorry for the two posts, but as a new user I can only put two links in one post.)
You need to install the latest nightly build.
Then try this vfd.conf. I think that the icons are not correct, but you should get the time.
x96-max-ultra-vfd.conf (1.2 KB)
If icons are wrong, you’ll have to play with vfd_dot_bits or you can do that with the openvfd service in kodi.
Please let me know what the correct config for the dot bits is.

First of all, thank you for your quick help. It was an inattention that I mixed up the data and the clock in the configuration.
I’m a bit stuck again with the configuration. I found the values:
USB=0, Card=1, High Wifi=2, Low Wifi=3, Col=4, Apps=5, LAN=6, N/A=7
Neither display type 2 nor 3 is not show all the possible values. Only display type 3 can handle both Low Wifi and High Wifi icons at the same time.
I have checked the source code and there is no behavior required for this display.
https://github.com/arthur-liberman/linux_openvfd/blob/master/driver/controllers/fd628.c
Best results so far (depending on which icons you prefer to see):
vfd_dot_bits=‘7,7,7,6,4,2,3’
vfd_display_type=‘0x03,0x00,0x01,0x00’
or
vfd_dot_bits=‘5,7,0,1,4,7,7’
vfd_display_type=‘0x02,0x00,0x01,0x00’
Any idea?

you have activated the time on the display at X96x4
Does OpenVFD run in Coreelec-ne ? I installed it but I don’t see /usr/lib/systemd/system/openvfd.service and there is no dmesg output.
Edit: it is working with the current version.
VFD for X96 x4?
Hello my device is S905x3 4gb ram /32 rom I put x96air rom on the device, the front led does not work, can you help me?

I will need cat /sys/kernel/debug/gpio from Android, not from CoreELEC.
Also, what’s the full name of the device?
