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??????????
Actually, it's a C question. putchar(temp) would actually work if temp was a char. If you want to learn how to send data without using printf but using putchar only, read any book on C. - Mike
