Topic: hd44780 driver using GPIO pins

The content of this topic has been archived on 4 Apr 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

I created a simple kernel driver for hd44780-based LCD displays using GPIO pins.

You can get it from SVN:

$ cd trunk/packages
$ svn co http://linux-adm5120.svn.sourceforge.ne … rt/hd44780

You will need to edit the source to change pins to suit your router.

It can be tested with:

echo -n "hello world" >> /dev/hd44780.

It's very basic, and doesn't handle control codes, but may be of use all the same.

please give me link dowload source
