Need a little help!

Hello everyone,

          I am needing some help with a little problem. 

      What I have is a  Serial Graphic Display. To display strings the string has to be terminated with a null byte(0). Using my pic compiler its easy. With  Arduino it is a little more complicated... at least to me. can someone give me some pointers? Thanks.

Hi there,

The best place for general Arduino programming questions is the arduino.cc/forum. 

They have lots of clever people helping in the forum  Smiley

Hi Charlie42,

in C, the standard is the a character string ends in 0 (null). If you use standard library routines like strcat(), strcopy() etc., the null is added automatically. If you build your strings from some algorythm, you must append the null at the end, for example:

Code
Select All
char SomeString[15]
      
      SomeString[0] = ...
      ...
      SomeString[i] = ...
      SomeString[i + 1] = '\0'; // adds the terminating character

Hope that helps  Smiley.
