Below in conjunction with accompanying drawing, patent of the present invention is further described.
As shown in Figure 1: the composition frame chart being present system, it is characterized by: ARM chip 1 is the control core of curve assessment, this chip is connected with FLASH chip 3 with liquid crystal touch screen 1, tool graphical user interface emWin is adopted to carry out the Display designing at curve assessment interface, process the configuration information of sending from liquid crystal touch screen 2, and the parameter of the assessment combination method set and every quantum evaluation is sent to FLASH chip 3 stores.
As shown in Figure 2, the present invention adopts TSC2046 chip to control touch-screen, and this chip and ARM chip carry out exchange data by SPI communication mode, and with ARM chip PF6 in the present invention, PF7, PF8, PF9 pin multiplexing becomes SPI mode to carry out the control of TSC2046 chip; The principle that TSC2046 chip reads coordinate is as follows: when measuring X-coordinate, first by writing control word to touch screen controller, make to apply the voltage determined on X+ and X-, and not making alive on Y+ and Y-, then will form the parallel voltage field of uniformly continous between X+ and X-.When touching touch screen surface with finger or felt pen, the voltage at contact place reflects the position of contact on X workplace.This voltage is drawn out to touch screen controller by Y+ or Y-electrode, then through wherein A/D conversion, just can obtains the digital quantity of contact voltage, i.e. X-coordinate.Also Y-coordinate is recorded by same principle.Controller only needs the reading digital quantity by timer timing.The present invention adopts emWin to be interface instrument, and after initialization completes liquid crystal and touch, the application interface function that just can call in emwin storehouse carries out interface.
As shown in Figure 3, ARM core of the present invention is connected with outside FLASH chip by SPI port, and outside FLASH chip of the present invention adopts W25Q64BVSSIG, and its capacity is 8M byte, up to the SPI clock frequency of 80MHz, after initialization completes, just read-write operation can be carried out to it.
As shown in Figure 4: be that liquid crystal touch screen curve assessment of the present invention arranges interface schematic diagram.This arranges interface and comprises: thread window window is arranged, arranged by window window, block window window is arranged, envelope window arranges four parts.Wherein: if click thread window button, the then highlighted display of this button, represent in curve assessment content and comprise thread window appraisal procedure, window 1 arranges the lateral length of thread window window, window 2 arranges the longitudinal length of thread window window, after being provided with, application interface function G UI_DrawRect (int x0 drawn by the frame calling emWin, int y0, int x1, int y1), x0, y0 is the left apex coordinate of thread window the preview window, x1 is the lateral length that x0 adds thread frame, y1 is the longitudinal length that y0 adds thread frame, the thread window window then arranged shows in real time in units of pixel in preview 1, if click through window button by, the then highlighted display of this button, represent and comprise by window appraisal procedure in curve assessment content, window 3 is arranged through the curve approaching side (upside of window, downside, left side and right side), the curve that window 4 is arranged through window leaves (upside, side, downside, left side and right side), window 5 is arranged through the lateral length of the window of window, window 6 is arranged through the longitudinal length of the window of window, after being provided with, also call the identical frame of emWin and draw the parameter that function fills out correspondence, what then arrange is shown in real time in units of pixel by window window in preview 2, if click block window button, the then highlighted display of this button, represent in curve assessment content and comprise block window appraisal procedure, the longitudinal length that window 7 arranges the lateral length of block window window, window 8 arranges block window window, after being provided with, after being provided with, also call the identical frame of emWin and draw the parameter that function fills out correspondence, then the block window window arranged shows in real time in units of pixel in preview 3, if click envelope button, the then highlighted display of this button, represent in curve assessment content and comprise envelope appraisal procedure, what window 9 arranged envelope plays/only horizontal ordinate, window 10 arranges the width of envelope, after being provided with, on primary standard curve basis, what arrange with window 9 plays/stops the lateral length interval that horizontal ordinate is envelope, the width that the data arranged with window 10 are envelope, one group of polygon array is depicted by function, then call application interface function G UI_DrawGraph () and draw out typical curve function, the filling that application interface function G UI_FillPolygon () carries out region setpoint color is called again in the position of correspondence, draw envelope shade.
As shown in Figure 5, give the curve assessment method to set up main program flow chart of ARM controller in the present invention, in this master routine, initialization IO port, initialization liquid crystal display, initialization touch setting, initialize Timer, initialization emWin, call emWin interface function design interface respectively, and Open Timer device interrupts.
As shown in Figure 6, timer interrupt service program flow diagram of the present invention is given.In timer interrupt service program, touch scan interface function G UI_TOUCH_Exec () calling emWin inside scans touch-screen, when there being external touch information, entering in the call back function of emWin at once and processing corresponding touch information.Because each control of emWin distributes different ID, be pressed so just different controls can be differentiated according to different ID in call back function, then do corresponding process.
As shown in Figure 7, emWin call back function program flow diagram of the present invention is given.First judge whether that opening window is arranged according to the return function of interface function, and determine whether thread window successively, by one or more in window, block window and envelope four kinds of appraisal procedures, parameter in corresponding four kinds of assessment modes is set according to the result returned, and preserves interface and parameter in the outer FLASH chip of sheet.
