Raspbmc & HD44780 LCD

Followed the instructions at: http://www.tech-fruits.com/archives/4388 to setup my HD44780 LCD, and confirm that everything is running beautifully.

All that is needed is a

Code: Select all

sudo update-rc.d LCDd defaults

to get LCDd initialised on startup.

Using this with a few amendments to the text file to display CPUTemperature and IP Address when under some of the menus in XBMC. But the degrees symbol is the wrong character. Anyone know whether this is configured in a file that can be altered easily.
The degrees symbol requires changing from Chr226 to Chr223.
I posted this on the other page a few weeks ago but no answers yet, so posting here to see if anyone has ideas / comments.

Rather than using one of those japanese characters, it would be better to use a single user defined Custom Graphic character, memory locations from 0 to 7. That way it would just use a single character combined. I did this for my picaxe driven beer thermometer :

Thanks for the tip. The problem is that the character string and the degrees symbol used is embedded in the code within XBMC (I assume) used to give CPUTemp. In python I've managed to strip / add characters to create the text string I want on the LCD display using the degrees character rather than a simple " 'C ". Everything else within LCDProc and the XBMC works well and I'm no expert in software to know where to look to change it (or if it's possible without editing the system code).

Is it possible to display other character sets such as Japanese / Russian characters via RASPBMC using this LCD?
I've got it set up and working in English; but changing the language in RASPBMC results in gibberish on the LCD. Some character sets (e.g. Russian) look fine on my HD display (but not LCD) but others, Japanese, Arabic etc do not even display on the HD screen or the LCD.
Any ideas?

Hi,
you are restricted by the character set that is built into the display ROM, or by using the CGRAM characters.

Thanks Texy ... looks like I need to find another display then.
