my problem is i want to send data to the serial port without using printf, this is because i want to read data of the serial port to use in another application. but using printf takes too long to run as i want my program to run at a speed less than 1mS. any help as soon as possible would be very helpfull??????????
"what i want to do is put a variable "temp" onto the serial port" What is temp - char? int? pointer? string? ... If you find that printf is too cumbersome, you will need to write your own routines to suit your specific requirements; eg, * write a byte from XDATA space in hex; * write an int from DATA space in signed decimal; etc, etc...
