Accordingly, the embodiment of the invention also provides a kind of starting terminal with memory method, comprises the boot-strap circuit that the foregoing description provides, and as shown in Figure 3, described method comprises step:
111, when terminal is in open state, master controller is changed to first state with the level of GPIO interface; Concrete:
When the terminal processes open state, the terminal master controller is changed to high level (also can be changed to low level) with the GPIO interface of appointment.
112, microcontroller is first ident value according to the data of the first state designated memory address of described GPIO interface; Concrete:
Microcontroller is changed to 1 (also can be changed to 0) according to first state (high level) of GPIO interface with designated memory address date (last time closed machine information and preserve the position).
113, when described terminal powers on, described microcontroller obtains described storage address data, if described data are first ident value, determines that then shutdown last time of described terminal is illegal shutdown, and described microcontroller carries out the Memorability start.
Concrete: when described terminal powered on, microcontroller at first started, and loaded the storage address data of above-mentioned appointment automatically, if be 1, then the last shutdown of explanation is illegal shutdown, and microcontroller will be carried out the start electrifying timing sequence, start shooting.
In the method, further comprise:
When the terminal normal shutdown, primary controller (is distinguished level second state that is changed to of described GPIO interface with described first state mutually, if described first state is a high level, this second state is a low level so, opposite, if first state is a low level, this second state is a high level so), and notify described microcontroller that described storage address data are become second ident value (if first ident value is 1, this second ident value is 0 so);
That is: when the terminal normal shutdown, in shutdown process, master controller will specify the GPIO interface to be changed to low level (also can be high level, level during with open state is distinguished mutually and is got final product), this master controller notice microcontroller is with the above-mentioned address date zero clearing of storer, and this moment, described second ident value was 0;
When described terminal powered on, described microcontroller obtained described storage address data, (was: 0), determine that then shutdown last time is normal shutdown, does not then carry out the Memorability start if described data are second ident value.Because when terminal is illegally shut down owing to factors such as accident power-offs, the normal shutdown process of master controller neither one, the clear operation that can't notify microcontroller to carry out the above-mentioned address date of storer, at this moment the storage address data still are 1.So can be 1 to confirm that be illegal shutdown last time according to these data.
