Least-significant byte and most-significant byte digital quantity, most-significant byte and least-significant byte digital quantity be combined into 16 bit digital quantity uint xsz_ by microcontroller
Out, acquiescence output dimension is mil (mil), is shown into mil and calculated, and first determines whether the span of xsz_out, if
In [0x0000,0x Α Α Α Α] is interval, output data is the just symbol of Gun Trunnion Resolver Date Output
Number position is shown as " 0 ", corresponding to send aobvious FPGA registers to be set to led1_buffer [6]=0x3f, if in (0x Α Α Α
Α, 0xFFFF] it is interval interior, output data is negative, and the sign bit of Gun Trunnion Resolver Date Output is shown as
"-", led1_buffer [6]=0x40 is set to corresponding FPGA registers, while calculating xsz_out=0x10000-
Xsz_out because axes-angle conversion module output [0x0000,0xFFFF] totally 65536 code values correspond to respectively (- 500mil,
1000mil], then 1 code value correspondence 0.02288818, m meters il calculates value the float xsz_mil, xsz_mil=xsz_ for exporting
Out × 0.02288818mil, xsz_mil retain 2 significant digits and convert the data into corresponding binary-coded decimal, are respectively written into
1~7 data register of FPGA, 14 frequency division modules, 14 data registers and 14 data is set up in FPGA and send aobvious module,
14 frequency division modules are input into the frequency of crystal oscillator, crystal oscillator frequency is sequentially allocated and send aobvious module to 14 data, make it by corresponding data
Data in register give LED charactrons.If angle-data is exported, 65536 code values correspond to respectively (- 30 °, 60 °], then 1
Individual 0.00137329 ° of code value correspondence, value the float xsz_angle, xsz_angle=xsz_out that calculating is exported ×
0.00137329 °, out-degree, the corresponding data of minute, second being calculated respectively, writing 1~7 data register of FPGA, data send aobvious mould
Block can be by the Refresh Data in register to LED charactrons.As long as 14 frequency division modules ensure cycle period<20ms, people counts soon
Code pipe is there will be no the sensation that data flash.
Step 3,4 lines connection microprocessor control port of 4 × 4 matrix keyboards, it is low level to draw, and 4 alignments connect
4 I/O input ports of FPGA are connect, by exporting with door to the I/O delivery outlets of FPGA, the external interrupt with microcontroller
It is connected.When no button is pressed, high level is exported with door, after any button is pressed, microcontroller is made with door output low level
Device enters interrupt response function, performs keyboard scan program, and determination key coding=row scan values+column scan value judge that key is encoded
Into corresponding processing routine, 16 kinds of key codings and its treatment function are had.
Step 4, in Angle unit transform computing unit, presses【Angle Input】Button, microcontroller response button
Message, Angle Input lamps are bright, put flag bit flag2=1, Degree shown in mil Unitconversion such as Fig. 1 (b),
The led separations of " degree " " dividing " " second " are lighted, while setting data input counter led2_counter=7, keystroke is put manually
Panel, continue input 7 buttons, Degree mil Unitconversion show corresponding data from left to right successively, be often input into one
Individual button, counter subtracts led2_counter-- certainly, while the binary-coded decimal correspondence of data is stored in into 8~14 data registers of FPGA
Device.First incoming symbol position, if input " positive number " when, press【0】If being input into negative, press【—】, then it is input into two parallactic angle degree
Value, two parallactic angle score values, two parallactic angle seconds values after the completion of input, are pressed【OK】Button, program performs conversion and calculates, according to flag bit
Flag2 is to need execution angle value to be converted to mil value knowable to 1 to calculate, according to angle mil relation：360 °=6000mil, i.e.,
1 °=16.66667mil, the mil value after conversion can be calculated, then the mil value for calculating retains 2 significant digits, by number
According to 8~14 data registers of correspondence write-in FPGA, aobvious module is sent by FPGA data, 8~14 data registers are sent successively
Enter Degree mil Unitconversion LED charactrons, while Angle Input lamps go out, mil Input lamps are bright, put mark
Will position flag2=0.Similarly, press【Mil Input】Button, microcontroller response press key message, Mil Input lamps are bright, put mark
Will position flag2=0, Degree mil Unitconversion such as Fig. 1 (c) it is shown, light " individual position led separations, while setting
Put data input counter led1_counter=7, keyboard region clicked on manually, continue input 7 buttons, Degree mil
Unitconversion shows corresponding data from left to right successively, is often input into a button, and counter subtracts led1_ certainly
Counter--, while the binary-coded decimal correspondence of data is stored in into 8~14 data registers of FPGA.First incoming symbol position, if defeated
When entering " positive number ", press【0】If being input into negative, press【—】, four integers are then input into before decimal point, it is input into after decimal point
Two bits, after the completion of input, press【OK】Button, program performs conversion and calculates, the needs according to knowable to flag bit flag2 is 0
Perform mil value and be converted to angle value calculating, according to mil angular relationship：6000mil=360 °, i.e., 1mil=0.06 °, can count
Calculate the angle value after conversion, then calculate the data of " angle " " angle point " " rad ", by the 8~14 of data correspondence write-in FPGA
Data register, aobvious module is sent by FPGA data, and 8~14 data registers are sequentially sent into Degree/mil
The LED charactrons of Unitconversion, while mil Input lamps go out, Angle Input lamps are bright, put flag bit flag2=1.
Step 5, clicks on【CLR】Button, microcontroller respective keys are interrupted, and will write 8~14 data registers of FPGA
Middle zeros data, and【mil Input】Lamp goes out,【Angle Input】Lamp goes out.
