Re: ANSI font or extended character set

I got it now. As berni-v mentioned, The DMD and DMD2 librairy is not able to display these characters because the character index used a "char" variable. A simple change to "unsined char" corrects the limitation. For DMD2 that means changing DMD2-Text.cpp in the library folder. Line 41: char c = let...

Re: ANSI font or extended character set

I found this solution, but I'm not sure how to apply it to the DMD2 library:

Re: ANSI font or extended character set

Thanks angusgr,

I tried to use the Latin-1 font from the DMD library to work with the DMD2 library but I cant display characters above 127. As I can't use DMD library, is there any chance for me to have Arial_Black_16_ISO_8859_1.h runing with DMD2?

Best,

ANSI font or extended character set

Hello, is it possible to make an ANSI font to use with the DMD? I need to display German umlauts ÜÄÖ and ß. I tried to extend one of the fonts from the DMD2 library but its only an ASCII set. "Schön" is displayed "Schn". This is an important issue for my project. It has to work with the German langu...

Re: Displaying text in multiple lines

Here is an example to handle text. After I tried something else (it was not very efficient) I got help from the arduino forum - works perfect: char str[] ="Hello World! Here is some text. I need to break it into multiple lines without splitting the words."; const int wantedLength = 20; const char * ...

Re: Displaying text in multiple lines

Thanks a lot for the hint. I will look into it soon. I'm not totally new to Arduino but new when it comes to complex string handling. I hope I can figure it out by my own. I use an Arduino Mega (Gboard pro, Mega with GSM) and it's working just fine with 20 DMD's daisy chained - if you only send some...

Displaying text in multiple lines

Hello, I'm working on a big DMD screen with 20 modules (working so far). For now I'm testing it with only 8 (4x2) DMD's. I'm using an Arduino which gets text messages with a maximum of 200 characters. The message should be displayed on the DMD screen afterwards. I need a way to display the text in m...
