Customised characters on LCD

Hello everybody,
I'm trying do create a special character on a 2-line, 16-character LCD. I think I know, how it works
at the LCD side but failed so far, implementing it in Flowcode 4. I assume, it's the WRITE_RAM
macro in the LCD component macro, where the 1. parameter is the GCRAM address and the
others the "pixels" of the character. Is this assumption correct? And if so, how do I get this
character onto the display.
An other question is also, how to retrieve a character from CGRAM and display it on the panel?

Regards

Hi Ben,
thanks for the quick answer. Yes, I noticed it. But since it was posted already in Aug. 2008, I considered it as outdated. Is it really necessary to change the source code nowadays? Can it not be done by means of the LCD component macro?

Hello,

The Panel will not react to your custom characters, real world hardware should work fine.

The function is now included into the default LCD component but I sent you the link to the article so you could see how to use the function.
