Problems solved by technology

When two electronic devices communicate, the sending clock at the sending end and the receiving clock at the receiving end may be different. When the frequency difference between the sending clock and the receiving clock is too large, it will cause sampling misalignment at the receiving end, resulting in receiving errors and lower communication efficiency.
[0003] In addition, when only two wires are used for communication between electronic devices, power supply / charging is usually not possible during the communication process, and other external power sources are required, which brings great inconvenience to the use of electronic devices. Therefore, There is an urgent need in the art for a method of power supply / charging when only two wires are used for communication

Abstract

The invention discloses a transmission parameter acquisition method and a terminal thereof. The transmission parameter acquisition method comprises the following steps of acquiring waveform sequence characteristics of N waveform sequences formed by X preset level jumps, wherein each waveform sequence possesses the following waveform sequence characteristics that transmission duration of each waveform sequence is the same and is inversely proportional to a Baud rate; a first waveform sequence keeps a high level at the beginning and generates a low level in time of duration; total time of the low level during transmission duration does not change along with the Baud rate; a second waveform sequence stays the high level in the transmission duration; a third waveform sequence starts with the low level and ends with the high level; the total time of the low level during the transmission duration does not change along with the Baud rate; and the X preset level jumps are jumped into the low level from the high level; detecting the X level jumps at a receiving port; and according to a time interval of any two of the preset and detected X level jumps, calculating the transmission duration of the waveform sequences.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a transmission parameter acquisition method and a terminal. Background technique [0002] The serial communication method between electronic devices is usually transmitted character by character, each character is transmitted one by one, and when transmitting a character, it always starts with a "start bit" and ends with a "stop bit" , there is no fixed time interval requirement between characters. When two electronic devices communicate, the sending clock of the sending end and the receiving clock of the receiving end may be different. When the frequency difference between the sending clock and the receiving clock is too large, it will cause sampling misalignment at the receiving end, resulting in receiving errors and lower communication efficiency. [0003] In addition, when only two wires are used for communication between electronic devices, power supply / charging...
