Microporcessor Wont Recieve Data From Comp

My microprocesser wont recieve data from my comp, i've used hyparterm, telnet, and linkit-123
but none of them wont transemit data to my MPu. yet i see a recieve mode in the Link menu
why?

  • more words, please

    a few basic questions
    1) you do have a MAX232(equivalent) between the UART and the 'compensator', I hope
    2) do you get nothing or garbage if you constantly transmiy 'U'?
    3) are you cabled correctly (RS-232 cables comes in 'straight' and 'crossed') and you must use the cable that match yur connections at the uC

  • "My microprocesser wont recieve data from my comp"

    OK, so it's a pretty good guess that "comp" means "computer" here - but having to guess doesn't help.
    The more clear and complete you make your description, the more likely you are to get good replies!

    "i've used hyparterm, telnet, and linkit-123"

    Hyperterminal is a plain text terminal emulator;
    Telnet is an internet protocol;
    I have no idea what "limkit-123" is.

    Are you sure that you had all these tools correctly configured - speed, parity, handshaking, etc?

    "but none of them wont transemit data"

    How do you know that they won't transmit?

    Your first step has to be to determine where the problem is:

    Is the PC transmitting correctly?
    Is the data reaching the microcontroller's pins correctly (ie, correct & working cabling, correct & working RS232 transceiver, correct & working board connections, etc)?
    Has your software correctly configured the UART, etc?

    "i see a recieve mode in the Link menu"

    What is a "receive mode"?

    What "link menu"?

    I fixde it bcoz teh cable was not in.
