Android system is the operating system based on Linux, and the Booting sequence of Android system is roughly divided into three phases：Boot
Loader guiding mboot starts, and mboot guiding linux kernels start, application program loading.In the prior art, smart machine
Backlight panel light flow and be mainly and guide what linux kernel startup stage completed in mboot, also, backlight panel lights
Whole flow process in, the operations of main control chip are sequentially carried out.
It is as follows, the whole flow process lighted to backlight panel of in the prior art, being started shooting from smart machine is illustrated：
Figure 1A is referred to, is that the backlight panel of smart machine lights one of schematic diagram of flow.As shown in Figure 1A, Boot
After Loader guiding mboot starts, the main control chip that smart machine is provided with is initialized to GPIO first, afterwards directing switch
Single-chip microcomputer is initialized, wherein, switch single-chip microcomputer is be exclusively used in controlling dynamic backlight data transfer after smart machine start one
Single-chip microcomputer, main control chip has been guided after switch single-chip microcomputer startup, display screen is initialized according to screen specification book, screen
After the completion of initialization, main control chip control GPIO exports a high level signal, the high level signal is referred to as into SW signals, with logical
Know that MCU and backlight control chip that the power supply chip that smart machine is provided with is externally connected on power panel are powered, in MCU and the back of the body
After photocontrol chip is both powered up, MCU carries out the configuration of backlighting parameters to backlight control chip so that backlight control chip foundation
The backlighting parameters of MCU configurations light backlight panel.
Figure 1B is referred to, is the schematic flow sheet that MCU is configured to backlight control chip.As shown in Figure 1B, wherein, the back of the body
Photocontrol chip by taking 7027 chips of dialog companies as an example, power supply chip that smart machine is provided with according to SW signals, to MCU and
7027 power supply after, 7027 carry out first the initialization of itself, i.e., 7027 initially enter can steady operation state, while MCU
Also the initialization of itself is carried out, for example, configures running parameter, initialization SPI (the Serial Peripheral of itself
Interface, Serial Peripheral Interface (SPI)) controller, etc. operation.Subsequently, after MCU and 7027 initializes completion, MCU can taste
Examination is communicated with 7027, to detect the data path between MCU and 7027, such as SPI paths, or I2C (Inter
