Most LCD units have the degree symbol already... Location 0xDF in the character set... So just use..

LCDdata(oxDF);

Or the function that applies to you.

i understand...the symbol of Celsius degree was already store in memory of LCD....
so for my custom character the only way is the Lcddefchar command...am i right?
Thanks for the reply Ian...

Yes... The custom characters are locations 0 ~ 7 and also 8 ~ 15 but these are duplicates.

You need to write the command "0x48" and then the special characters.. 8 per character..

Ooops!! I have just realized you are using Oshonsoft... Yes!! the Lcddefchar is correct..


Lcddefchar 0, %11111, %10001, %10001, %10001, %10001, %10001, %11111, 0

Makes a square..

The hitachi series lcd controllers do have a custom character memory you can setup your own characters, I did it a while back its a right pain to do, I was designing a system that displayed the measurement of a vehicle engine 02 sensor on a lcd using a vertical bargraph made from custom characters.
