How do I display Greek letters on my LCD?

[GreenLeader]

I am using a Picaxe 40X1 and a 4x20 LCD with the FRM010 firmware chip. I can display ASCII numbers, text etc without any problem.

But I can't work out how to display special characters like the degree symbol or Greek characters.

Searched the forum but no luck. Could anyone point me in the right direction?

Not really sure, but I think this is a good start: http://www.hippy.freeserve.co.uk/picaxelc.htm#User_Defined_Characers

You need to identify the character value of the symbol you want ( in my LCD datasheet the Ohm symbol is $F4 ) then send that ...

- SerOut ... ( "ABC", $F4 , "DEF" )

and remember all LCD character sets tend to be different on different brands/models, so you need the exact datasheet of your specific model LCD

Or define a custom character (usually you can have 8 at one time).

I did this when I wanted a £ sign.

Ohh it's easier than I though then....

Or mindlessly write out all the characters one at a time maybe with a 1 second pause between each one, from (binary) 0 to 255 and see what the display does with them.

I chose the mindless option and used the simulator . Found my degree symbol - its 223

serout 6,(254,128,223)


thanks

Be careful though, not all LCD's nor the simulator may have the same characters or the same characters in the same place. If it doesn't display the right character resort to the showing one-at-a-time method with a real LCD.
