HD44780 20x4 LCD

Post by zanga » 2019/11/12 15:44:49

Hello,

Is anyone aware of any package that can be used to display info on this LCD screen?
In the past there was LCD4linux and LCDproc but it seems the support for them has been dropped.

Thanks !

I checked this: https://en.wikipedia.org/wiki/Hitachi_H ... controller

I searched the page but didnt get any results for usb. Does it have a usb interface? Else how are you connecting it to the system? Does it show up in /dev/
Can you get a usb interface and will it work via usb? I googled and found this: https://diyrobocars.com/2019/03/31/how- ... ys-not-to/

BTW I have no idea about the LCD screen but I am interested in it so please post back :)

I've managed to make some progress.

I build the lcdproc package using COPR(including the missing dependencies).
If anyone needs them they are available here:
https://copr.fedorainfracloud.org/coprs ... ackages/  

Now everything seems to be working pretty well with my display.
