Embodiment Construction

[0031] As mentioned in the background, at present, when the touch screen of the mobile terminal is damaged and fails, it will not be able to normally generate an interrupt signal, so that the system cannot obtain the touch signal on the touch screen, thereby affecting the stability of the system. In this case, the mobile terminal can only be repaired, which not only increases the cost but also causes poor user experience.

[0032] In order to solve the above problems, in the technical solution of the present invention, the touch signal on the touch screen is obtained by adding a polling module and setting an interrupt flag bit. Specifically, the polling module inquires whether the interrupt flag bit is set at a predetermined interval, and when the interrupt flag bit is in the first state (that is, an interrupt signal is generated), the control right is given to the interrupt module, and the polling module exits . And if there is no interruption of data generation, the touch s...

Abstract

Provided are a data acquisition device and a mobile terminal. The data acquisition device is suitable for being connected with a touch screen to obtain touch signals on the touch screen, and comprises an interrupt module, a roll poling module and a storage module, wherein the storage module is suitable for storing interrupt flag bits which comprise a first state and a second state. The interrupt module is suitable for setting the interrupt flag bits at the first state after receiving interrupt signals and for obtaining the touch signals on the touch screen. The roll poling module is suitable for detecting the states of the interrupt flag bits in a preset interval time, and obtaining the touch signals on the touch screen when the interrupt flag bits are at the second state. According to the data acquisition device and the mobile terminal, the roll poling module and the interrupt flag bits are arranged additionally so that touch signals on the touch screen can be obtained through the roll poling module after the touch screen loses efficacy, and the stability of a system is improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a data acquisition device and a mobile terminal. Background technique [0002] With the development and progress of technology, the field of mobile communication technology has changed rapidly, and various types of mobile terminals have been widely used. Among them, mobile terminals with touch screens are very popular among users. [0003] In the prior art, most mobile phones are equipped with touch screens, and more capacitive touch screens are used. At present, most capacitive touch screens in mobile phones use an interrupt mode. When the touch screen is touched, the touch screen generates an interrupt signal to notify the mobile phone system to read the touch signal on the touch screen. [0004] However, sometimes the touch screen cannot generate interrupts, for example, the mobile phone is squeezed or the mobile phone is accidentally dropped, resulting in damag...
