Hello,

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

Is openvfd supposed to work with hbs658 ?

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:

2445.369925] OpenVFD: Detected gpio chips: periphs-banks, aobus-banks.

[ 2445.369929] OpenVFD: is_right_chip periphs-banks | periphs-banks | 0

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
