Re: [Sdcc-user] LCD print("string") function?

[<ron...@ao...>]

Thanks for the reply. On your reccomendation, I looked at some print examples, but didn't need anything as powerful as printf.
I just created a print_LCD (unsigned char* message). function. Here's the working code for anyone at my level...

void WriteLCD( unsigned char* message )
{
?unsigned char i;
?
?for( i=0; i<32; i++ )
?{
??if( !message[i] )
???break;
???
??DATA_OUT(message[i]);
?}
}??
Thanks for the lead.

If you define your own function putchar to send characters to the LCD, you can 
use printf to print strings. It should call your putchar routine.
