Embodiment Construction

[0041] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0042] Such as figure 1 As shown, in the method and device embodiment of the present invention for connecting multiple external devices on an embedded platform, the method for connecting multiple external devices on an embedded platform includes the following steps:

[0043] Step S11 Connect the device to the interface of the embedded platform: for the embedded platform, it must have multiple physical interfaces for connecting peripheral devices, and these interfaces may include multiple types for connecting different types of peripheral devices. The number and type of these interfaces are determined in advance. However, the specific parameters of the peripheral devices connected to these interfaces cannot be determined in advance. In addition, there is also the case of physical interface multiplexing, that is, one physical interface may be able to con...

Abstract

The invention relates to a method for connecting various kinds of external equipment to an embedded type platform, which comprises the following steps of: connecting equipment to an interface of an embedded type platform; sending out a registration request by the equipment and registering the equipment on an equipment interface module of the embedded type platform; and regulating a function pointer describing the interface by the equipment interface module so as to enable the function pointer to point to a function position corresponding to the registration type of the equipment. The invention also relates to a device for realizing the method. In execution, the method and the device for connecting various kinds of external equipment to the embedded type platform, which are disclosed by the invention, have the following beneficial effects that: the workload is smaller, and the method and the device for connecting various kinds of external equipment to the embedded type platform are flexible and are convenient to search problems.

Description

technical field [0001] The invention relates to the field of embedded processors, more specifically, to a method and device for connecting various external devices on an embedded platform. Background technique [0002] For the current embedded system platform (usually with an embedded processor as the core), its system resources are becoming more and more abundant, and there are more and more peripheral interfaces, and more and more peripheral devices are supported; at the same time , in current applications, more and more peripheral devices need to be connected to the platform. The increase of devices connected to the embedded system platform makes the development of the devices more complicated. According to the traditional connection method between peripheral devices and the platform, the driver of the peripheral devices connected to each interface is set separately on the platform, but this method also has some disadvantages. First, the workload is relatively large....
