Currently I'm using a C8051F120 microcontroller to receive information from a demodulator via UART. However, now I'm required to recieve data in non-UART format (without start and stop bit).

Currently the demodulator doesn't support bus line. I would like to ask what are the recommended methods to read signals(square wave) from the demodulator and display on the computer? It could be direct connection from the demodulator to the computer without using the microcontroller.

Also If I were to use a bus line, how would the implementation be like?
 

hi

the start and stop bits can be found in almost all formats may be in different way. that improves the data integrity
if you don't want them just try to write a simple program that send/ receive.

Hi,

If i were to write a simple program that send/ receive.
1) How do i ensure the synchronization of the data in say 1200bps, having only one wire each for both send and receive?
2) How to ensure that the send and receive are full-duplex?
3) If possible, do you have any similar sample code? or guide me on what i would need to do.
Thanks for your help.
