Abstract
The invention discloses a slot-sharing T card and SIM card detection method. According to the slot-sharing T card and SIM card detection method, one of an SIM card detection module and a T card detection module is used as a hot plug detection module; an interrupt pin of the hot plug detection module is used for detecting whether a card is inserted in or pulled out of a slot; when it is detected that the card is inserted, the hot plug detection module sends a corresponding detection instruction, the other detection module not serving as the hot plug detection module is driven through an interrupt function configured in the hot plug detection module to send a corresponding detection instruction, and therefore the card inserted in the slot is identified through the two detection modules. According to the slot-sharing T card and SIM card detection method, identification of a T card and an SIM card which share the slot can be realized through only one interrupt detection pin, and one GIPO resource is saved.
Description
Technical field
The invention belongs to communication technical field, particularly a kind of detection method of draw-in groove T card and SIM card altogether.
Background technology
Existing a lot of mobile terminal all will use SIM card and T card, wherein SIM card and T card are placed in corresponding draw-in groove separately, in order to meet consumers' demand, be user-friendly to multiple Mobile Directory Number, more existing mobile terminals are set to the form of double card or many cards, namely in a mobile phone, arrange multiple sim card slot, but for most of user, substantially be all use Mobile Directory Number, therefore unnecessary sim card slot just causes certain wasting of resources.But there is certain difference in the structures such as existing sim card slot and T draw-in groove, if sim card slot and T draw-in groove to be designed to the words of common draw-in groove, namely a draw-in groove not only can place SIM card but also can place T card, due to the restriction of structure, SIM card only supports Nano SIM, therefore the hardware of draw-in groove must arrange for SIM card and T card respectively and interrupt detecting pin, causes the consumption of certain bus extension GPIO (General Purpose Input Output, universal input/output) resource.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art and deficiency, a kind of detection method of draw-in groove T card and SIM card is altogether provided, this detection method only needs one to interrupt detecting pin can detect the T card and SIM card that insert in same draw-in groove respectively, has saved GPIO resource.
Object of the present invention is realized by two kinds of technical schemes, wherein realizes the object of the invention first technical scheme as follows: a kind of detection method of draw-in groove T card and SIM card altogether, and step is as follows:
One of them detection module in X1, setting T card detection module and SIM card detection module is as the hot plug detection module of draw-in groove, and interrupt processing function is inserted/transfers in configuration in this detection module;
Card whether is had to insert or extract in X2, hot plug detection module test card slot; When the interruption detection pin level of hot plug detection module changes, then represent in draw-in groove and have card insert or extract, enter step X3;
X3, when hot plug detection module detect in draw-in groove have card insert or extract time, start insertion/dial-outs interrupt processing function wherein, judge that in draw-in groove, card inserts or dial-out, if insertion, then enters step X4, if extract, then enter step X5;
