Embodiment
The invention provides indicator light control method when a kind of mobile terminal charges and mobile terminal, for making object of the present invention, technical scheme and effect clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Indicator light control method during mobile terminal charging provided by the invention, as shown in Figure 1, it comprises:
S100, when mobile terminal connects power supply, open the indicator light controlling functions of mobile terminal.When mobile terminal inserts charger or connects computer by USB, the unlatching charge function of mobile terminal, indicator light controlling functions is opened automatically.
S200, the baseband chip magnitude of voltage when the scheduled time reads battery charging.Wherein, the described scheduled time is 2-5S, such as when charging, baseband chip can read magnitude of voltage during battery charging every 5 seconds.
S300, baseband chip calculate its GPIO(General Purpose Input Output according to magnitude of voltage, universal input/output) the mouth side of output wave frequency, make indicator light by this frequency scintillation; Wherein, the flicker frequency of indicator light with battery voltage value increase and slack-off, and when battery is full of electricity, indicator light is extinguished.
During concrete enforcement, described baseband chip output duty cycle is the square-wave signal of 50%, and when baseband chip calculates its GPIO mouth side's of output wave frequency according to magnitude of voltage, by following formulae discovery:
Wherein, Vbat is the battery voltage value that baseband chip reads, and Vmax is the maximum voltage value of battery, and Vmin is the minimum amount of voltage that of battery, and fmax is the maximum square wave frequency that the GPIO mouth of baseband chip is preset.
As can be seen from above-mentioned formula, the baseband chip side of output wave frequency is slack-off gradually with increasing of battery voltage value, visible cell voltage and square wave frequency linear, as shown in Figure 2.As can be seen from Figure 2, when cell voltage Vbat becomes large, frequency f diminishes; For mobile phone, current mobile phone battery is pressed between 3.4 ~ 4.2V, so can to get Vmin be 3.4V, Vmax is 4.2V; If LED flicker is too fast, human eye perceives will as normal bright the same, so fmax can get 2, when battery electric quantity is minimum, indicator light 0.5s flicker once.When battery electric quantity is full of, battery voltage value Vbat is equal with the maximum voltage value Vmax of battery, and therefore square wave output frequency f is 0, and namely battery is full of electricity, and it is that low level makes indicator light extinguish that baseband chip then arranges its GPIO mouth.
