Make a global vairiable to decide what device. (or Add routine to printf and export...)
You may edit printf routine to reference this.
You will set and reset this variable in caller routine...
PS: Printf routine is very heavy. Do not try make "printf"....

HI,
Before of all I think that you must consider if you really need to use printf (need lot of code and time to execute). So, if you need only to print text on the LCD (without formating values) you can use the lcd.c library (found easly on the web, if you whant it, let me know).
The functions inside are simple and you can make easly a function to write values.
Hope Help
