How to configure VFD

Hello, thanks for your precious informations. I got my A95X F2 display to work perfectly. It just misses 1 thing: when I turn the box off, the display is completely dark, it doesn’t show the little standby dot , is it possible to add it in some way? thank you

The driver turns off the display when CoreELEC is turned off. I don’t think it’s a good idea to change this behavior, which can cause problems with other devices using this driver.

I tried VFD for my Tanix TX5 Pro (S905X2 with 4GB/100Mbit) with g12a_s905x2_4g.dtb and tanix-tx5-max-vfd.conf, but the display only shows “boot”.
It seems to be a simple four character display, nothing fancy.
original dtb (via dd if=/dev/dtb | gzip > /storage/downloads/dtb.img.gz while in CE):
maybe you could give me a hint how to get the display showing the 24h time?
Thank you!

is seems due to systemctl openvfd status that openvfd is not there? but the addon in installed and dmsg shows something:
cat /sys/kernel/debug/gpio
gpiochip1: GPIOs 410-495, parent: platform/pinctrl@ff634480, periphs-banks:
gpio-448 ( |amlsd ) out hi
gpio-458 ( |amlsd ) in lo
gpio-474 ( |openvfd ) in hi
gpio-475 ( |openvfd ) out hi
gpio-482 ( |sdio_wifi ) out hi
gpio-483 ( |sdio_wifi ) in hi
gpio-493 ( |bt_rfkill ) out hi
gpio-495 ( |bt_rfkill ) out hi

gpiochip0: GPIOs 496-511, parent: platform/pinctrl@ff800014, aobus-banks:
 gpio-498 (                    |line_mute           ) out hi
 gpio-506 (                    |openvfd             ) out hi
 gpio-507 (                    |?                   ) out lo

I’ll take a look when I get back from work.
cat /sys/kernel/debug/gpio in Android might be helpful, in CE it serves no purpose as it uses the config in the vfd.conf file you used.

Ok, can you try this vfd.conf?
tanix-tx5-pro-vfd.conf (1.2 KB)

WUHU! its is working.
your file wasn’t perfect, but the char order wasn’t that hard :wink:
since I still cant upload files, that did the trick:

Thank you so much!

Great, I’ll add it to the repository.
So just to confirm, the above file with the change you posted works correctly?
Does the : (colon) blink?

it would be nice to have a vfd config for S905X3 X96Max plus 4/32.Gb

I’m sure that there is a working vfd.conf for that box already, need to search in the x96max thread.

this is a new “x96max plus” .s905x3.

the vdf of “x96max” s905x2 I have not got it to work on “x96max plus s905x3” for my.

s905x2 X96Max x96-max-1gbit-vfd.conf not working on new X96Max + S905X3 box

That conf file should work, at least according to the screenshot above.
Please post a dmesg, maybe that will tell us why it’s not working.
