In the present application, the method is performed by a device 1, where the device 1 is a smart terminal and/or an industrial device terminal supporting a touch screen, and the smart terminal and/or the industrial device terminal includes, but is not limited to, a smart phone, a tablet computer, a game machine, a smart vending machine, a cash register, a road direction directing machine, and the like supporting a touch screen function.
The smart terminal and/or the industrial device terminal are only examples, and other existing or future devices and/or resource sharing platforms, as applicable to the present application, are also included in the scope of the present application and are herein incorporated by reference.
In this embodiment, the device 1 is a smart phone developed based on the high-pass SM6125 platform. In step S11, the device 1 has no dedicated Flash configured in the module without the Flash touch screen to store the firmware file of the touch screen. The flash-memory-free touch screen may be a structure based on an in-cell (function of the touch panel is embedded in a liquid crystal pixel) scheme, or an on-cell (touch screen is embedded between a color filter substrate and a polarizer of a display screen) or an OGS (touch screen and protective glass are integrated together, a conductive layer is plated on the inner side of the protective glass, and film coating and photoetching are directly performed on the protective glass) scheme, and other touch screen structures are also included in the protection scope of the application if applicable to the application, and are not limited in the application.
Wherein the device 1 also supports flash-free touch screens produced by different vendors. For example, in this embodiment, based on the high-pass SM6125 platform, it is possible to adapt the flash-free touch screen produced by different vendors by modifying the relevant parameters in the device tree and the relevant macros in the kernel configuration file.
Before using the non-flash touch screen of the device 1, the non-flash touch screen needs to be started or awakened, and a firmware file of the non-flash touch screen is loaded to complete initialization of the non-flash touch screen.
Firstly, the firmware file of the flash-memory-free touch screen needs to be stored in a memory on a main board of the device 1, the solid file of the touch screen may be obtained by downloading the device 1 from a computer or other devices through a network, or may be obtained by downloading the device 1 from a computer or other devices directly connected through a software tool, and other obtaining methods, such as being applicable to the present application, should also be included in the protection scope of the present application, and are not limited in the present application.
And after the device 1 acquires the solid file of the flash-memory-free touch screen, storing the solid file into a memory on a mainboard of the device 1.
Continuing in this embodiment, in step S12, the firmware file of the flash-free touch screen is sent to the RAM in the flash-free touch screen module through the medium/low speed bus of the smart terminal.
The solid file of the touch screen stored in the memory of the mainboard is sent to the RAM of the flash-memory-free touch screen module for caching through a medium-low speed bus between the mainboard and the flash-memory-free touch screen module in the device 1.
Preferably, the medium low speed bus comprises an SPI bus.
The commonly used medium-low speed buses in the device 1 are an IIC bus and an SPI bus.
The IIC bus is connected with the master device and the slave device through two lines, and has the characteristics of a half-duplex mode, a low transmission speed and the like, for example, if the IIC bus is adopted, the firmware file loading time of the flash-free touch screen is long, the initialization time of the flash-free touch screen is too long, the abnormality is easy to occur in the initialization process, and the user experience is poor.
The SPI bus is connected with the master device and the slave device through four wires, the full duplex mode is realized, the transmission speed is high, the short loading time of the firmware file of the flash-memory-free touch screen can be ensured, and the flash-memory-free touch screen is normally initialized.
Preferably, before the storing the firmware file of the flash-free touch screen into the memory of the intelligent terminal, the method further comprises:
and finishing the setting of the working mode parameters of the SPI bus of the intelligent terminal, wherein the working mode parameters comprise the clock polarity and the clock phase of the SPI bus.
The four wires of the SPI bus include: SDI (SerialData In), master side data input, slave side data output; SDO (serial data Out), master side data Out, slave side data in; SCLK (Serial Clock), a Clock signal generated by a master device; CS (chip select), slave enable signal controlled by master. The four operation modes SP 0-SP 3 are realized by two-two combination of two parameters of CPOL (clock polarity) and CPHA (clock phase) of SCLK, wherein,
SP 0: CPOL is 0, CPHA is 0, the level is low when the clock is idle, data is collected at the front edge of the clock cycle, and data is output at the back edge of the clock cycle.
SP 1: CPOL is 0, CPHA is 1, the level is low when the clock is idle, data are collected at the back edge of the clock period, and data are output at the front edge of the clock period.
SP 2: CPOL is 1, CPHA is 0, the level is high when the clock is idle, data is collected at the front edge of the clock cycle, and data is output at the back edge of the clock cycle.
SP 1: CPOL is 1, CPHA is 1, the clock is high when the level is idle, data are collected at the back edge of the clock period, and data are output at the front edge of the clock period.
The operation mode of the SPI in this embodiment may be any one of four modes selected by setting the CPOL parameter and the CPHA parameter.
Preferably, before storing the firmware file of the flash-memory-free touch screen into the memory of the intelligent terminal, if the intelligent terminal is in a deep sleep state, the method further includes:
and awakening the intelligent terminal to complete the power-on starting of the SPI bus.
If the device 1 does not use the non-flash touch screen or other functions for a long time, in order to reduce power consumption and prolong the battery service time, the device 1 usually turns off the non-flash touch screen to enter a deep sleep state, and the SPI bus communication of the device 1 is turned off. When the touch screen needs to be used again, the device 1 needs to be awakened, and the SPI bus is powered on again and started again before the firmware file of the flash-memory-free touch screen is stored in the memory of the intelligent terminal.
For example, in this embodiment, based on the development of the high-pass SM6125 platform, the device 1 in sleep can be woken up by setting an interrupt.
Specifically, by registering a callback function and setting parameters, modifying a relevant interrupt service function, and judging whether the device 1 is awakened from a sleep state or not through program operation in the awakening process of the device 1, communication with the flash-memory-less touch screen can be performed based on the SPI bus.
Continuing in this embodiment, in step S13, the loading of the firmware file of the flash-free touch screen is completed by executing the firmware file loading instruction of the flash-free touch screen, reading and executing the firmware file in the RAM in the flash-free touch screen module.
Further, the method for loading the firmware of the flash-memory-free touch screen of the intelligent terminal further comprises the following steps:
if the loading is unsuccessful, the firmware file of the flash-memory-free touch screen is retransmitted to an RAM in the flash-memory-free touch screen module based on a medium-low speed bus of the intelligent terminal;
operating the firmware file loading instruction of the flash-free touch screen to complete the loading of the firmware file of the flash-free touch screen;
and if the retransmission times exceed a preset time threshold, prompting the loading failure.
Because the flash-free touch screen is adopted, the solid file of the flash-free touch screen needs to be loaded into the RAM in the flash-free touch screen module every time the touch screen is started, the solid file loading may be unsuccessful when the loading process is abnormal or the circuit of the flash-free touch screen works abnormally, and if the solid file of the flash-free touch screen is loaded unsuccessfully through the steps S21-S23, the steps S22 and S23 are repeated until the repetition times exceed the preset times, and the loading failure is prompted.
