Abstract

A method and device for upgrading the touch screen firmware of a mobile terminal are provided. The method includes: reading the touch screen firmware version information which is stored in the user space of the system into the kernel space of the system; according to the read firmware version information, upgrading the touch screen firmware by simulating an upgrade protocol through the General Purpose I / O (GPIO) ports of the touch screen. The present invention, simulates the upgrade protocol through multiplexing the GPIO ports of the clock pin (SCL) and the data pin (SDA) which are used for the I2C communication and on the hardware connector of the touch screen, thus implementing the automatic upgrade of the touch screen firmware on the mobile terminal, reducing the workload of upgrade, raising the upgrade speed, and facilitating the use.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for upgrading touch screen firmware of a mobile terminal. Background technique [0002] With the widespread application of smart phones, touch screens play an increasingly crucial role, especially capacitive touch screens, which will lead the major touch screen market in the future because of their long life, touchable fingertips, and ease of use. It is possible to completely replace resistive touch screens. However, as a new thing, the technology of capacitive touch screen is not perfect enough, and the firmware version is often updated. Sometimes it is necessary to solve some bugs (such as linear drift, misreported data, partial failure, etc.), compatibility issues, or require manufacturers to provide more information. For updated functions, it is necessary to upgrade the firmware of the touch screen. [0003] The existing technology is to upgrade the...
