So far, achieve when adopting HSIC bus interface to connect WIFI module, the normal hibernation of WIFI module and waking up.
Embodiment 6
Below by way of a concrete scene, the present invention is described in detail.
First, because adopt HSIC bus interface to be connected to WIFI module, so the course of work of WIFI module must follow HSIC bus inferface protocol completely, as shown in Figure 8.After the device adopting the CPU of the present embodiment by the mode of HSIC bus interface connection WIFI module starts, HSIC bus interface can be in IDLE mode of operation, and (namely the strobe signal strobe of HSIC bus interface is for high, data-signal data is low), at this moment WIFI module electrifying startup, when WIFI module detects that HSIC bus interface can send connection request when being in IDLE mode of operation, be set to low level by strobe, data is set to high level.If CPU detects HSIC bus interface, strobe is now set to low level, data is set to high level, then connection request sends successfully, and now WIFI module and HSIC bus interface connect.Then, CPU downloads WIFI module by file storage module and drives file and WIFI module firmware file, and sends to WIFI module.WIFI module is enabled WIFI module and is driven file and WIFI module firmware file, and WIFI module is normally worked.The startup of WIFI module that Here it is and the course of work.
Secondly, if need to enter dormant state, in all buses of so described device, the modules of carry all will enter dormant state, and WIFI module is no exception.But because HSIC bus interface itself does not have the function of hot plug, if namely from dormant state (disconnecting with HSIC bus interface), to again waking up (again communicating with HSIC bus interface), now CPU cannot detect WIFI module to WIFI module.Therefore, the present embodiment unloads WIFI module and drives file and WIFI module firmware file when described device will enter dormant state, disconnect the power supply of WIFI module and HSIC bus interface, allow the state of HSIC bus interface and WIFI module come back to the state before powering on for the first time when dormancy.When described device needs to wake up from dormant state, again according to the process that first time WIFI module powers on and works, realize the normal work of WIFI module, as shown in Figure 9.
S901:HSIC bus interface is energized, and is in IDLE duty; Meanwhile, WIFI module also powers on, and when WIFI module finds that HSIC bus interface is in IDLE duty, the strobe signal of amendment HSIC bus interface and the level of data-signal, make HSIC bus interface in running order; Now, CPU detects that HSIC bus interface is in running order, and detecting that the other end of HSIC bus interface is WIFI module, then CPU downloads the WIFI module of WIFI module should drive file and WIFI module firmware file and send to WIFI module from file system;
S902:WIFI module receives and enables the WIFI module that CPU sends and drives file and WIFI module firmware file, and WIFI module is normally worked; And the data interaction of CPU and WIFI module is realized by HSIC bus interface;
S903: when CPU receives dormancy instruction, sends sleep request to WIFI module, if now WIFI module is just at transfer files, data can not be stopped to transmit, then enter step S904; Otherwise, enter step S905;
S904:WIFI module continues normal work;
