Abstract

The invention provides an electricity-taking communication device, a mobile terminal and a communication method and system of the electricity-taking communication device and the mobile terminal. The electricity-taking communication device samples a voltage value of a signal provided by the mobile terminal, a pulse time sequence signal is generated according to a sampling result, and the pulse time sequence signal and a clock signal of the mobile terminal are synchronous. An MIC terminal of an interface module and an MIC terminal of the mobile terminal are mutually connected to form an MIC access, and under the action of the pulse time sequence signal, the electricity-taking communication device is communicated with the mobile terminal through the MIC access in a two-way mode. In addition, according to the two-way communication, a mature I2C bus protocol can be used for transmitting data, so that the transmission speed is higher, and stability is higher.

Description

technical field [0001] The invention belongs to the technical field of communication, in particular to a power-taking communication device for communication based on an earphone jack, a mobile terminal and a communication method and system thereof. Background technique [0002] With the development and progress of technology, various mobile terminals have widely entered people's lives. In the existing technology, external devices need to be used to expand their functions, because external devices need interfaces to connect with mobile terminals, and mobile terminals generally It has a 3.5mm headphone jack that conforms to the OMTP standard, so using the headphone jack as a communication interface for additional equipment has strong versatility. [0003] At present, the data communication scheme between the external equipment and the mobile terminal through the earphone jack as the communication interface is as follows: the external equipment uses the earphone jack as the com...
