Abstract

The invention provides a touch screen firmware upgrading method and a touch screen firmware upgrading device for a mobile terminal. The method comprises the following steps of: reading firmware version information of a touch screen, which is stored in a user space of a system, into a kernel space of the system; and simulating an upgrade protocol to upgrade touch screen firmware according to the read firmware version information through a general purpose input / output (GPIO) port of the touch screen. In the invention, the upgrade protocol is simulated by multiplexing the GPIO ports of a serial clock pin (SCL) and a serial data pin (SDA) which are used for I2C communication on a hardware connector of the touch screen, so the automatic upgrading of the firmware of the touch screen can be carried out on the mobile terminal; therefore, the upgrading workload is reduced, the upgrading speed is high and the invention is convenient to use.

Description

Technical field [0001] The present invention relates to the field of communications, and 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 are playing an increasingly important role, especially capacitive touch screens, which will lead the main touch screen market in the future due to their long life, touch with the belly of the fingers, and ease of use. It is possible to completely replace the resistive touch screen. However, as a new thing, capacitive touch screen technology is not perfect enough. The firmware version is often updated. Sometimes it is necessary to solve some bugs (such as linear drift, messy data reporting, partial failure, etc.), compatibility issues, or more from the manufacturer. To update the function, it needs to upgrade the firmware of the touch screen. [0003] The prior art uses special tools to upgrade the firmware o...
