How to configure VFD

Coreelec-33 · 17 February 2023 14:54

Hi,
I finally found a solution to my problem. I reinstalled CE ng 20.0 instead of CE ne, and the display works correctly with the conf x96-max-ultra-vfd.conf in the post above.
Thank you.

Používám CE20-NE na stejném boxu jako TY. A displej mi funguje.

Thank you for your reply Borec1. I did a NE installation from scratch and indeed it works and without installing OPENVFD. But anyway bluetooth does not work with NE, nor with an Asus BT400 dongle unlike NG. Is this also the case for you? Thank you

Bluetooth mi také funguje. Je třeba ho povolit. Udělal jsi to?

Coreelec-33 · 20 February 2023 11:17

Yes i did it. It isn’t recognized, neither the dongle. The dongle is recognized by NG, but not the box BT

Hi. I have box BLOW: BLOW
I do not have the original firmware, I use modified sbx_x96mini_atv_9_3
I have copies of the BLOW partitions reserved.emmc.win and boot.emmc.win from which I extracted the DTB (I made them once in TWRP).
I replaced the DTB (_aml_dtb.PARTITION file) in the slimbox firmware with AMLogicTools_V7.1.0_Donate with the original remote control it works again
Unfortunately, the display does not work.

I installed CoreELEC 20.0 and try to run VFD but it doesn’t work. I am using gxl_p281_2g
OpenVFD service installed but probably not working:

Try this VFD.

Wow, you’re amazing
It works but badly. Now I’m using CoreELEC 19.5 Matrix:

TheCoolest · 4 March 2023 13:58

This should fix the time, but icons will probably not be correct.

jzef · 4 March 2023 14:14

Better and now the time works. I noticed that if the ethernet cable is connected, there is a colon between the hour and the minute. When I disconnect the cable the colon disappears.
The network icon flashes:

TheCoolest · 4 March 2023 14:55

Can you check which icon lights up if you connect to wifi?

jzef · 4 March 2023 15:17

Wifi does not work - does not detect Wifi - only Wired connection.

TheCoolest · 4 March 2023 15:18

Ok, try this:

jzef · 4 March 2023 15:30

Now it’s even better. There is only time and the colon is blinking

the VFD display shows fine but Kodi is wrong about one hour earlier.

TheCoolest · 4 March 2023 15:33

You can set it in the Settings → Interface → Regional

jzef · 4 March 2023 15:37

I didn’t have this setting - I changed it to Poland and now it’s OK

Hi there, I have a Wechip V9 S905X3 4GB (Wechip V9) and installed Amlogic-ng.arm-19.5-Matrix-Generic with sm1_s905x3_4g device tree. All works fine, except front display stays black, despite trying almost all S905X3 vfd.conf I could find. Seems as if something is occupying that gpio pin. Please help!

Here is GPIO from Android 9:

And here is the dmesg OPenVFD output using t95-max-plus-s905x3-vfd.conf:

Which icons does this display have?
But try this one:
wechip-v9-vfd.conf (1.2 KB)

jairoxyz · 12 March 2023 22:43

Wow it works! Thousand thanks.

@TheCoolest
I got a X96 Max+ Ultra 4GB RAM, 100Mbps Ethernet phy

It has 6 icons (going top to bottom, starting on left)

1st column

USB
CARD

2nd column
3. Top Half of WiFi
4. Bottom Half of WiFi

3rd column
5. APPS
6. Wired Ethernet

I am using x96-max-ultra-vfd.conf provided here.
I am booting from MicroSD and connect wirelessly
The display shows the clock correctly, and as for the icons, it is lighting up

APPS
The Bottom part of the WiFi icon

How to get it to show CARD instead of APPS and the full WiFi icon (if applicable). Thanks a lot for your continued support
