How to configure VFD

General Guides & How-tos
705

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?

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.

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

Check your openvfd addon configuration in Kodi. Disable the advanced section or disable the addon completely, then reboot.

This device seems to be using some very odd configuration.
Try this file, let me know if you can see anything on screen.
