Title:
CALIBRATION APPARATUS FOR LOW VOLTAGE I2C COMMUNICATION, SYSTEM, AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/125653
Kind Code:
A1
Abstract:
The present application relates to a calibration apparatus for low voltage I2C communication, a system, and a method. The calibration apparatus comprises: an excitation trigger module, which is used for sending a control signal to an IO control module in response to a calibration instruction of a digital system, so as to control the IO control module to generate an SCL signal and an SDA signal; a delay module, which is used for executing delay processing on the SCL signal and the SDA signal; and a calibration determination module, which is used for being able to correctly capture a delayed SDA signal in response to a delayed SCL signal, and for sending a first indication signal to the delay module. According to the solution provided by the present application, calibration can be performed on an SCL signal and an SDA signal of low voltage I2C communication, an implementation process for the solution is simple and convenient, and automatic calibration can be achieved.
