I successfully used the following approach: I have one function that
writes one
character, that is passed with the function call:
void LCDputc(unsigned char c)
{
...
/* Insert code for writing one character to LCD */
...
}
...and then I have another function for writing strings, which works
exactly like this:
void LCDputs(unsigned char *s)
{
while(*s) {
LCDputc(*s++);
}
}
Then, if you call
LCDputs("Hello World");
it will call the function LCDputc passing a character and then
increment the pointer to
the string, until it reaches the end of the string.
Hope this helps,
Robert
