#84191 - NOT A PIC Responding to: ???'s previous message |
Thanks for response. Actually I am working with 89c51, Of course there is THE UART but I am using it input from another source.
Question arises I may use the UART for both purpose by multiplexing or somehow, but I cant due to the requirements. Actually I used Hyperterminal to receive the output. This is what I did actually. 1)COnnected P1^0 from Serial out of PC. 2)Connected TxD of mcu with Serial In of PC. 3)Used hyperterminal with "different settings". 4)Timer1 overflow rated determine the both baudrate of serial port and data input interrupt for TF1_VECTOR. 5)Typed a charcter in Hyperterminal which was received by mcu and transmitted by it as well and result was received on PC. Results are as follows. MCU BaudRate ||| HyperterminalBaudRate ||| CorrectData% 2400 ||| 2400 ||| 60% 4800 4800 30% 1200 1200 80% 4800 1200 100% What does the results show I need to multiply it by 4 or so. Any further comments are welcome. Regards Mr. Naveed |
