A mobile terminal pin configuration method and system

Abstract

The invention relates to the technical field of mobile terminals, and discloses a configuration method and system of a mobile terminal pin. The method comprises the following steps of: storing a preset quantity of pin numbers and a list of pin modules corresponding to the pin numbers in a mobile terminal in advance; when the mobile terminal is started, copying the pre-stored list, and when the mobile terminal detects that the pin module is started, judging whether the pin module is in the presence in the list or not; and when the pin module is in the presence in the list, after the pin number corresponding to the pin module in the list is configured, carrying out same configuration on the remaining pin numbers in the list. When the mobile terminal is started, a plurality of pins which are used for detecting different functions can be correctly configured and connected into a whole, then, interrupt triggering is carried out by the same trigger source, so that each detection pin can be reasonably configured when the mobile terminal is started, and the system can normally work.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a method and system for configuring pins of a mobile terminal. Background technique [0002] In the prior art, mobile terminals sometimes adopt such a design: multiple pins for detecting different functions are connected together, and then the same trigger source is used for interrupt triggering. [0003] figure 1 It is a schematic diagram of the design scheme of two SIM cards in a typical application. Such as figure 1 As shown, the detection pin of SIM card 1 and the detection pin of SIM card 2 are configured as double-edge interrupt in advance, and the double-edge includes: rising edge and falling edge, and the process of the rising edge changing from low level to high level, The process of the falling edge changing from high level to low level will trigger an interrupt whether it is a rising edge or a falling edge. After SIM card 1 and SIM card 2 are put in...

Problems solved by technology

[0005] Although the above two designs can save space and allow multiple cards to be placed together, they also bring about a problem. The start-up time of the detection module of each card is uncertain, and there must be a problem of start-up time. For example, When starting up a certain time, for example, the SD card detection module starts before the SIM card detection module. After the SD card startup module starts, it configures the SD card detection pin correctly, and then starts the interrupt detection of the SD card pin, but at this time the SIM The card has not been activated yet, the SIM card detection pin has not been correctly configured, and the level detected by the SIM card is uncertain, because the SIM card detection pin is connected to the SD card detection pin, which will always affect the SD card detection pin. state until the SIM card detection pin is configured correctly after the SIM card detection module starts

In some special cases, for example, the level of the SIM card detection pin is just near the interrupt threshold. The threshold is a voltage value. Generally speaking, there are two thresholds, such as threshold 1 and threshold 2. The former is greater than the latter. When the voltage is lower than the threshold 2, it is considered to be a high level, and when the voltage is lower than the threshold 2, it is considered to be a low level; this will cause frequent interruptions during the period from the start of the SD card detection module to the start of the SIM card detection module, so that the SD card detection The module is triggered, so that the system is busy with interrupt processing, making the boot slow, or even crash
