More Information
Summary:The invention discloses an expansion device and electronic equipment, and relates to the technical field of electronics, the expansion device comprises a control chip, a data transmission line and an expansion module, the expansion module comprises a GPIO expander, a memory and a function expansion module connected with the GPIO expander; the control chip is respectively connected with the GPIO expander and the memory through data transmission lines; the memory is used for storing pin occupation information of the GPIO expander and read-write address information of the expansion module; and the control chip is used for determining the function extension module to be called according to the pin occupation information and performing data interaction with the function extension module to be called through the data transmission line. And the control chip realizes the extension of the GPIO interface by using the data transmission line and the extension module, so that the control chip supports more extension funct
