Problems solved by technology

This way, the number of pre-allocated and defined time slots limits the amount of data that the target device can transfer to the expander
For example, if 60 time slots are defined in advance for the target device to transmit data to the expander, the target device can only transmit 60 different data contents to the expander, and no more data can be added.

Abstract

The present invention provides a data transmission method of a universal serial input / output. The method is suitable for an expander and a target apparatus that are connected by a universal serial input / output bus. The universal serial input / output bus at least has a data output line and a data read line; the expander outputs a paging indication signal to the target apparatus via the data output line, wherein the paging indication signal indicates a paging address; the target apparatus, according to the paging indication signal, searches for paging data indicated by the paging address; the target apparatus outputs the paging address and the paging data to the expander via the data read line; the expander reads a content transmitted via the data read line; and when the expander determines that the content transmitted via the data read line has the paging address, the expander receives the paging data.

Description

technical field [0001] The present invention relates to a general serial input and output data transmission method, in particular to a data transmission method between an expander connected with a general serial input and output bus and a target device. Background technique [0002] With the development of technology, the demand for data transmission speed and data volume between electronic devices also increases accordingly. In order to cope with the rapid transmission of a large amount of data between electronic devices, the current technology will often use a general-purpose serial input and output (Serial General Purpose Input Output, SGPIO) bus or an internal integrated circuit (Inter-Integrated Circuit, I2C), a universal asynchronous receiver transmitter (Universal Asynchronous Receiver Transmitter) , UART) etc. for data transmission between the expander (Expander) or the initiator (Initiator) and the target device (Target). [0003] However, when the USB is used to t...
