LED (VFD) Displays in LibreELEC

Perfect, thanks!

Hello, for a long time absent. Did you use vfd on mxv+ s905?

Is the FD628 service only for OpenELEC? I'm currently using the latest CoreELEC and I got the clock working on my Sunvell T95 using the T95m vfd.conf file, but none of the other icons light up. I tried to find the FD628 service, but it's not available. Is it possible to manually install this add-on for CoreELEC?

Kashim You need to install the OpenVFD Service from the CE repository.

Thanks, that worked!

Hello! I got an U2C Z Pro (2/8GB, S905X) and tested the latest m9-pro-u2c-x-u5x-s-vfd.conf, but I can’t get it to work.

I found a dtb.img similar to my device. Someone over here contacted the official u2c seller on amazon.ca and got the official update file, containing the dtb.img. I’ll contact them, since mine is a U2C Z Pro, not U2C X Super, but the displays look exactly the same (without BT). The chip is a HBS658 and The Coolest mentioned it already over here: coreelec.org - Help with VFD.conf

Another thing I found is this: A user called hlyi published hbs658service on GitHub. I'm not sure how to compile, install it or if it's already included in the builds.

I also tried using gxm_q201_2g instead of gxl_p212_2g, since hbs658 it's mentioned here: GitHub Gist - aep / dts

But no luck.. It seems to be implemented for the S912 U2C devices, right?

hi The Coolest

[Edit: just realized I opened an old thread]

I see following error on RK3399 TV Box:

     Loaded: loaded (/usr/lib/systemd/system/openvfd.service; enabled; vendor preset: disabled)
     Active: inactive (dead)
  Condition: start condition failed at Sat 2020-01-11 01:34:31 UTC; 15min ago

Jan 11 01:34:31 LibreELEC systemd[1]: Condition check resulted in OpenVFD Service being skipped.

This is in manufacturer's DTS:

    skykirin_led {
        compatible = "skykirin-ht1628";
        spi_clk = <&gpio1 RK_PB1 GPIO_ACTIVE_HIGH>;
        spi_cs = <&gpio1 RK_PB2 GPIO_ACTIVE_HIGH>;
        spi_data = <&gpio1 RK_PB0 GPIO_ACTIVE_HIGH>;
        status = "okay";
    };

Let me know how to fix this

Hello,

I have a QINTEX-Q912 box with Amlogic S912 and hbs658.

Is openvfd supposed to work with hbs658 ?

In the original dtb, i found only info about two gpios:

hbs658 {

compatible = "amlogic, hbs658";

dev_name = "hbs658";

status = "okay";

gpio-scl = <0x24 0x4c 0x00>;

gpio-sda = <0x24 0x4b 0x00>;

};

I suspect these are for vfd_gpio_clk and vfd_gpio_dat, but I could not find the one for vfd_gpio_stb.

Thank you,

Paul

P.S. I attached the full dtc of the box

I got it working with bellow parameters, and the HBS658 controller is properly selected.

vfd_gpio_clk='0,76,0x10'

vfd_gpio_dat='0,75,0x10'

vfd_gpio_stb='0,0,0xFF'

vfd_chars='4,0,1,2,3'

vfd_dot_bits='0,1,2,3,4,5,6'

vfd_display_type='0x06,0x00,0x00,0x04'

The dmesg looks like this:

Hi, guys! I had S78 box, this is a rikomagic rkm mk25 clone on S922x. I got working the HBS658 vfd. Below is a chunk from dtb and config:

hbs658 {

compatible = "amlogic, hbs658";

dev_name = "hbs658";

status = "okay";

gpio-scl = <0x2c 0x17 0x0>;

gpio-sda = <0x2c 0x18 0x0>;

vfd.conf:

vfd_gpio_clk='0,0x17,0x10'

vfd_gpio_dat='0,0x18,0x10'

vfd_gpio_stb='0,0,0xFF'

vfd_chars='4,0,1,2,3'

vfd_dot_bits='0,1,2,3,4,5,6'

vfd_display_type='0x06,0x00,0x00,0x04'

Hello, I have a box tx3mini, I tried to put the configuration vfd for tx3 but the device stopped loading, the display only says boot, I am uploading photos of the chip, display and android dtb, please help me
