How add to configure channels name oled

24

Dare I ask why you have three (at least visible) heatsinks stacked atop one another?

25

The addon doesn’t support displaying channel information at the moment.

26

because all amlogic cpu head ver hot and burning :slight_smile:
I used big passive heatsinks. temperatures max 49-52 c all time. No

No, it only supports SSD1306/SH1106 OLEDs, a couple e-paper displays and PCD8544 (nokia LCD) displays. As far as I know, only OLEDs come with a I2C interface. For SPI displays you would need 6-8 IO pins.

I have updated K1 pro (s905d) to coreelec_ng (Linux CoreELEC 4.9.113). However, openvfd does not work. The error I got is below

Have you used the vfd.conf for the K1 Pro ?

31

Yes I used vfd.conf for i2c
