| Abstract: | The paper introduced the principle of universal asynchronous receiver transmitter STI6C554D and its application in code mixer, which based on MCS-51 MCU. Through sequentially transmit the two input signals from a digitat video record as well as a matrix mainframe to single output, the code mixer successfully solved the bus dispute and operation dispute between two inputs devices. This paper designed the hardware circuit as well as software frame of the code mixer. |
