Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining the present invention, rather than limitation of the invention.It also should be noted that, in order to just
Part related to the present invention rather than entire infrastructure is illustrate only in description, accompanying drawing.
Embodiment one
Fig. 1 is a kind of adjustment terminal touch screen anti-interference filtration module firmware parameter value that the embodiment of the present invention one provides
The schematic flow sheet of method, the method can be held by the device of adjustment terminal touch screen anti-interference filtration module firmware parameter value
OK, described device can be realized by software and/or hardware, can be built in terminal inner as a part for terminal, alternatively can
Enough and terminal enters the stand-alone product of row data communication.Referring to Fig. 1, the method specifically includes following steps:
Step 110, listening in the case that terminal and adapter set up and is connected to be charged, detection setting time section
Interior charging current parameter value.
In the present embodiment, watcher thread can be created, monitor whether a terminal is set up with adapter every the fixed cycle
Connect being charged.Listening in the case that terminal and adapter set up and is connected to be charged, detection setting time
Charging current parameter value in section.Wherein, charging current parameter value is including but not limited to: each time in setting time section
The range value of the charging current on node, the crest value of the charging current in setting time section and/or the crest value of charging current
Each timing node being located etc..In embodiments of the present invention, described crest value refers to the crest value of charging current amplitude.
Charging current parameter value in detection setting time section, can be particularly as follows: obtain the setting of reporting of charging module of terminal
The charging current parameter value fixed time in section.In embodiments of the present invention, the charging module of terminal is connected with adapter, can
