A kind ofly can judge correctly whether mobile phone passes through the method for RF calibration, it is characterized in that using aforesaid mobile phone, and it comprises the steps:
After the A control unit downloaded to memory cell with cell phone software, revising the quasivariable value of memory cell lieutenant colonel was default value;
B is after mobile phone is by the control unit calibration, and revising the quasivariable value of memory cell lieutenant colonel is the value that is different from default value;
Read the value of calibration variables during the C mobile phone power-on from memory cell by control unit;
D judges by judge module whether the value of calibration variables is default value, if, then not calibration, display unit shows the unregulated interface of expression; If not, then for what calibrate, display unit shows the calibrated interface of expression.
Describedly can judge correctly whether mobile phone passes through the method for RF calibration, it is characterized in that among the described step D:
If calibration, the clock during display unit shows and minute between have the space; If calibrate, the clock of display unit interface display and minute between do not have the space.
By technique scheme, the present invention's advantage compared with prior art is:
The present invention be directed to when downloading, under the improper operation calibration data is lost, cause battery[1] value become default value again, original method is because of " calibration is passed through " that do not change in the fixed area, can judge mainboard by accident for still calibrating, the present invention judges whether calibration according to the calibration data of reality very intuitively, can not do erroneous judgement.
Description of drawings
Fig. 1 is a structured flowchart of the present invention.
Specific implementation method
The invention provides a kind of mobile phone and method that can correctly judge whether through RF calibration.See also Fig. 1, it is a structural representation of the present invention, and as shown in the figure: it comprises control unit, memory cell, judge module and display unit.Wherein:
This memory cell is used to store and is used to represent whether mobile phone passes through the calibration variables and the RF calibration parameter of RF calibration;
This control unit is used for controlling the RF calibration flow process of mobile phone and (RF calibration of mobile phone is a kind of known technology in the value of calibrating flow process modification calibration variables, therefore repeat no more), and download flow process according to cell phone software and revise the quasivariable value of memory cell lieutenant colonel, and control the judgement of calibration variables and send display unit to show;
This judge module is used for judging according to the value of current calibration variables whether mobile phone passes through RF calibration, and send control unit with judged result;
This display unit is used for the judged result according to judge module, carries out different display modes to distinguish through calibration with not through two kinds of situations of calibration by control unit control.
Will just can implementing based on following hardware of this invention: memory module needs the flash of spansion, toshiba and samsung to support that big or small 64M or 128M can; Display unit needs lcd to support that the plate of lcd can be that letter profit, SVA and Chinese space flight etc. can be supported; Control unit is based on that radio-frequency module and calibration procedure together realize, radio-frequency module comprises what the PA of the transmitter of Aero and siliclab realized, and calibration procedure is that the PC section has the program of VC to realize; Judge module is based on spreadtrum SC6600D realization.
Use aforesaid mobile phone, realize judging that the method whether mobile phone passes through RF calibration comprises the steps:
After the A control unit downloaded to memory cell with cell phone software, revising the quasivariable value of memory cell lieutenant colonel was default value;
B is after mobile phone is by the control unit calibration, and revising the quasivariable value of memory cell lieutenant colonel is the value that is different from default value;
Read the value of calibration variables during the C mobile phone power-on from memory cell by control unit;
D judges by judge module whether the value of calibration variables is default value, if, then not calibration, display unit shows the unregulated interface of expression; If not, then for what calibrate, display unit shows the calibrated interface of expression.
Among the described step D: if calibration, the clock during display unit shows and minute between have the space; If calibrate, the clock of display unit interface display and minute between do not have the space.Certainly, can also set other different display mode with the expression two states.
Embodiment:
Mobile phone can be changed the value in part nv (non-volatile, the immutable) file when calibration, present embodiment is used in MMI (Man Machine Interface, man-machine interface) software also based on this.We when downloading cell phone software, the Battery[1 in mobile phone nv (non-volatile, the immutable) file down] value be 0, after calibration, this value has been changed, is certainly not to be 0 value.After this, when mobile phone is started shooting again, will read the Battery[1 among the nv (non-volatile, immutable) earlier] value, judge whether he equals 0, if equal 0, just judge calibration; If be not equal to 0, just judge to have calibrated and pass through; Then in the demonstration of standby picture to some extent the difference, the mainboard of calibrate, the demonstration hour and minute between do not have the space; If not have the calibration mainboard, the demonstration hour and minute between respectively have the space.Operator at this station of Function detection can judge directly once starting shooting whether this mobile phone was calibrated, if do not calibrate, the calibration station that just directly turns back to the front is done calibration.
Being preferred embodiment of the present invention only in sum, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of the present patent application claim change and modification, all should be technology category of the present invention.
