Embodiment Construction

[0024] Figure 5 It is a block diagram of the single-wire serial transmission protocol circuit of the present invention. exist Figure 5 Among them, the data transmission line 502 is a single-wire serial transmission protocol circuit that can be connected in parallel to several different interfaces, such as the single-wire serial transmission protocol circuit 506 of the interface A and the single-wire serial transmission protocol circuit 508 of the interface B. In order to facilitate the description of the circuit operation , the present embodiment is to give two single-wire serial transmission protocol circuits (such as Figure 5 The single-wire serial transmission protocol circuit 506 and the single-wire serial transmission protocol circuit 508 in the example, the circuit structure of the single-wire serial transmission protocol circuit 506 and the single-wire serial transmission protocol circuit 508 are the same) as an example. The 1-Wire Serial Protocol circuit 506 and t...

Abstract

The present invention is single-wire tandem transmission protocol method and circuit. The circuit includes one I / O port, one controller, one control buffer and one shift temporary storage device, and bi-directional tandem data are transmitted via single wire in different transmission rate.

Description

technical field [0001] The present invention relates to a transmission protocol method and circuit for serial data, and in particular to a transmission protocol method and circuit for bidirectional serial data transmission with a single line. Background technique [0002] The way of data transmission is divided into the transmission of serial data and the transmission of parallel data, and the transmission of serial data has I 2 C bus, UART (Universal Asynchronous Receiver Transmitter) and HDQ16 protocol and other technologies. [0003] figure 1 A structural diagram of a bus bar in the prior art is shown. exist figure 1 Among them, each device on the bus needs to transmit data to each other, and the two transmission lines SDA (Serial Data Line) 102 and SCL (Serial ClockLine) 104 complete the data transmission. The format of the bus transmission data is 8 For the serial transmission of the same aspect of the bit, the bus can transmit data in both directions. The standard ...
