Abstract

The invention discloses a signal transmission processing method, a signal transmission processing device and a signal transmission processing circuit. The method comprises the steps that a first module sends a target signal to a first level conversion module; the target signal is converted into a differential signal through the first level conversion module; the differential signal is transmittedto a second level conversion module, and the second level conversion module is used for converting the differential signal into a target signal; and the target signal converted by the second level conversion module is sent to the second module. Through the method and the device, the problem that signals are easily interfered in the transmission process when common-mode signals of TTL (transistor-transistor logic) level are adopted for signal transmission in IIC (inter-integrated circuit) communication in the prior art is solved.

Description

technical field [0001] The present application relates to the field of information transmission, in particular, to a signal transmission processing method and device, and a processing circuit thereof. Background technique [0002] In related technologies, since the advantages of IIC communication are simplicity and effectiveness, among them, IIC communication only needs two communication lines, SDA and SCL, so the IO (interface) of the controller is very saved, so IIC communication is very commonly used in the communication field , but IIC communication uses TTL level common mode signal, so the transmission distance is limited, and the signal is easily interfered during transmission. If during the signal transmission process, the signal line introduces surge interference, it will cause data transmission errors. [0003] For the above-mentioned problems existing in related technologies, no effective solution has been proposed yet. Contents of the invention [0004] The ma...
