this is manoj im using 89c52 microcontroller .im unable to transmit the data serilally for 115200 baud rate . but im able to transmit thro 9600 baud rate configuration.
i tried using X2 mode by configuring baud rate control register baud reload register pcon register clock control register
can anyone give the example for configuring the registers in x2 mode for baud rate of 115200
NO, not till you state 1) specificly which derivtive (89C52 is a general name, e.g. AT89C52 is a specific name) 2) what your clock speed is
Erik
AT89c52 ,24MHZ clock speed
i stucked up in another problem tat im not able to receive data serially when i use max 485 bus thro hyperterminal .i have used convertor to convert rs232 to 485 in between the pc and my target board im not able to receive the data .can u guide me
can u guide me I have no Idea if micro (u) can guide you, but haow are you handling receieve and transmit eanable on your 485 tranmsciever.
