problem with puthcar()

Nitin Skandan

I am using puthcar( ) function to send a series of bytes serially thru UART. My problem is that i cannot see the output through serial window of simulator . its printing just some junk values. when i am doing the same with printf(). I am getting response which could be observed from serial window.Can any one tell me why this is happening.

    "eg, if the value is 0xA5, it will print 'A5'"

    To be precise, since you specified the format string "[%x]", it will actually print "[a5]"

    "Whats the reason and how can it be corrected"

    You need to review your 'C' course notes/textbook/whatever and understand the difference between formatted output using printf, and direct output using putchar.
