Abstract

The invention discloses a self-adaptive single-wire asynchronous communication circuit, a communication method and a communication device. The self-adaptive single-wire asynchronous communication circuit comprises a sending end and a receiving end, and the sending end is composed of a sending data generation module and a voltage-current conversion module; and the receiving end consists of a current-voltage conversion module and a received data processing module. The sending data generation module is used for generating signal sequences with different widths; the voltage-current conversion module converts the level signal generated by the sending data generation module into a current signal and sends out the current signal; the current-voltage conversion module converts the current into a corresponding voltage; and the received data processing module processes the received data so as to realize asynchronous communication between the level power supplies. The invention aims to solve theproblem that digital logic interfaces with different power supply voltages in a multi-power supply system cannot directly communicate with each other, and realizes mutual data sending or receiving ofa low power supply voltage interface and a high power supply voltage interface.

Description

technical field [0001] The invention relates to the communication field, in particular to an adaptive single-wire asynchronous communication circuit, a communication method and a device. Background technique [0002] In a multi-power supply system, the digital logic control interfaces of different power supply voltages cannot communicate directly, and level conversion is required. In addition, for digital logic control interfaces with the same power supply voltage, SPI interface, I2C interface or CMOS parallel port are used to communicate in the form of voltage signal transmission, and data and clock must be sent and received synchronously at the same time. To sum up, it is really necessary to develop an adaptive single-wire asynchronous communication circuit, communication method and device, to solve the problem of inability to communicate directly between digital logic interfaces with different power supply voltages in a multi-power supply system, and to realize a low powe...
