using macros with multiple arguments!
PostPosted: Wed Feb 02, 2005 2:29 pm     Reply with quote

i want to define a printfLCD macro to print formatted text on lcd.

basic code may like this!
#define printfLCD(format, values???????) printf(format, value1, value2, value3 ... )

the problem is how many arguments i will print is not known. (also argument types are not known)

printfLCD("%s" , mystring);
printfLCD("%s %u" , mystring, myint);
printfLCD("%u %u" , myint1, myint2);
etc...

is it possible?

You probably want to use just the printf() command. You can specify it like this

Code:
printf(LCD_PUTC, "n=%u",n);


Where LCD_PUTC is the function that writes the characters to the LCD.
