Abstract

The invention provides a communication system comprising a first communication module, a second communication module and a single signal line, wherein the first communication module comprises a signal input end, a signal output end and a control end, the signal input end is used for receiving first sending signals, the signal output end is used for outputting the first receiving signals, and the control end is used for controlling the first communication module to be in the sending state or the receiving state; the second communication module comprises a signal input end, a signal output end and a control end, the signal input end is used for receiving second sending signals which are corresponding to the first receiving signals one by one, the signal output end is used for outputting second receiving signals which are corresponding to the first sending signals one by one, and the control end is used for controlling the second communication module to be in the sending state or the receiving state; and the single signal line is electrically connected between the first communication module and the second communication module, and is used for transmitting the first sending signals from the first communication module to the signal output end of the second communication module, and transmitting the second sending signals from the second communication module to the signal output end of the first communication module.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a communication system realizing single-wire bidirectional. Background technique [0002] In the field of communication, in order to realize communication between modules, the interfaces of each module are usually connected through two signal lines. However, this may lead to an increase in the number of interfaces of each module and require more design space to design interfaces. Therefore, One-wire communication is proposed by those skilled in the art. [0003] However, the current single-wire communication interface generally adopts an open-drain output method at the physical layer, and the bus uses a pull-up resistor to output a high level, or uses a weak pull-up method, the bus drive capability is poor, and the communication speed is difficult to improve. Specifically, The ability to drive high levels is poor, and the ability to drive low levels is relatively strong, w...
