Single-wire communication control method

According to the single-line communication control method, a notification stage is added at the beginning of data transmission, data transmission can be actively initiated, priority differentiation is achieved through a simple method for defining time length difference, one party with the higher priority transmits data preferentially, and low-delay communication is achieved; a periodic framing communication mode is adopted to ensure that the data transmission rate is stable, transmission delay can be further adjusted by changing the frame period, the method is particularly suitable for transmission of touch pad mouse type data, the bidirectional communication requirement can be met, and power consumption and data transmission efficiency are both considered; according to the invention, frame synchronization is realized by adopting interrupt wakeup, and clock calibration and synchronization between equipment and a host can be realized; the method can be compatible with a standard UART communication protocol, an
