in C51, the default printf() is used for serial comm., depends on putchar.c now, i'm trying to modify it(putchar.c) for my 8-bit LCD.
the question is, can putchar.c or printf() be used on both, serial comm. and 8-bit LCD, at same time (at the same main program)?
nb: i want to display floating point, that's why i'm trying to use printf()
