Hi technical guys,
When I use printf("This is test") in keil C to compile to get the hex code and burn it into 8051. It does not work even though I set the correct initilization baud rate for serial port communication. However, if I tried to use my send_serial("this is a test") function, it does work. I don't know why. Can you explain for me?
It is very appreciated if you can answer me this question.
Thanks, Stephen
