Fig. 1 is circuit theory diagrams of the present invention；

Description of reference numerals：Serial ports photographing module 1, camera 2, VDD draw angle 3, GND draws angle 4, shooting RX draws angle 5, shooting TX draws angle 6, U1 single-chip microcomputers 7, U1 one-chip computer modules 8, U1TX draws angle 9, U1RX draws angle 10, U1 serial ports B11, U2 one-chip computer modules 12；U2 serial ports A13, U2 serial ports B14, serial port extended chip 15, PC serial ports 16, PC 17, U1 serial ports A18, shooting serial ports 19, U2 single-chip microcomputers 20.

The present invention is described further with reference to the accompanying drawings and examples.Although the present invention will enter with reference to preferred embodiment Row description, it should be understood that being not offered as limiting the invention in the embodiment.It can be included on the contrary, the present invention will cover Alternative, modified and the equivalent in the scope of the present invention that appended claims limits.

As shown in figure 1, first, definition serial ports 1 is serial ports A, serial ports 0 is serial ports B.

The present invention principle be：ATmega128 (height matches somebody with somebody 8 series monolithics) realizes the program of a serial ports shooting, dress Two single-chip microcomputer U1 single-chip microcomputers 7, U2 single-chip microcomputers 20 are used in putting, U1 single-chip microcomputers 7 realize following functions：U1 single-chip microcomputers 7 are logical Cross U1 serial ports A18 and send commands to serial ports photographing module 1, serial ports photographing module 1 is beamed back photo data by imaging serial ports 19 To U1 single-chip microcomputers 7, U1 single-chip microcomputers 7 issue data by its U1 serial ports B11 the U2 serial ports A13 of U2 single-chip microcomputers 20 serial ports again The model GM8123 of extended chip 15, last U2 single-chip microcomputers 20 transmit data to PC 17 by U2 serial ports B14, on PC 17 Open COM Debug Assistant, it is possible to obtain the data of photograph.

(1) reception of serial ports and transmission program write debugging

In the present apparatus, the U1 serial ports A18 process that sends and receives all employ buffering area, i.e., first the number to be sent According to being saved in buffering area, if idle in the string of U1 single-chip microcomputers 7, data will be directly transmitted；If serial ports is Send or receive data, then data are saved in the buffer, are transmitted it out again when the serial ports free time.Here U1 serial ports Sending and receiving for A18 is all to use implement of interruption function.U1 serial ports A18 transmission program is first saved in the data to be sent slow Area is rushed, serial ports is then opened and interrupts.U1 serial ports A18 interruption sends the transmission that processing function is mainly responsible for data.U1 serial ports A18 Reception program in first determine whether receive buffering area whether have data.The data that single-chip microcomputer receives can occur in reception processing It is disconnected, the interruption reception processing function of serial ports 1 is triggered, is sent to transmission buffering area data are received, and the mobile buffering that sends refers to Pin.

(2) control program of serial ports photographing module 1 writes debugging

The model C 328 of serial ports photographing module 1 supports standard serial port output JEPG view data.The module has 4 pins：VDD Draw angle 3, GND draws angle 4, shooting RX draw angle 5, shooting TX draw angle 6, wherein shooting RX draw angle 5, shooting TX draw angle 6 respectively with U1TX Draw angle 9, U1RX draw angle 10 be connected, other two pins are grounded respectively and power supply.U1 single-chip microcomputers 7 are by U1 serial ports A18 to serial ports Photographing module 1 sends order, and after serial ports photographing module 1 receives order, response is sent to U1 single-chip microcomputers 7.The control string of U1 single-chip microcomputers 7 Mouth photographing module 1, use following several programs：Synchronization program；Initialization program；Data package size program is set；Send photo Operation sequence；Send and obtain the big small routine of sheet data of having taken a picture；Obtain photo data program.

(3) single-chip microcomputer U1 and U2 two machine communication programming debugging

The model GM8123 of serial port extended chip 15 of the U1 serial ports B11 and U2 single-chip microcomputers 20 of U1 single-chip microcomputers 7 phase of extension mouth 3 Even, if so U1 single-chip microcomputers 7 will send data, it is necessary to allow serial port extended chip 15 to be operated in serial ports 3 to U2 single-chip microcomputers 20 Under monotype.So U2 single-chip microcomputers 20 can receive data from serial port extended chip 15, then be sent to PC by U2 serial ports B14 On machine 17, the data of correlation are can be obtained by by COM Debug Assistant.

The experimental procedure of this experimental provision：(1) two files are established, one is U1, and one is U2, uses WinAVR points The code of correlation is not write, including：Synchronization program；Initialization program；Data package size program is set；Send photo operation sequence； Send and obtain the big small routine of sheet data of having taken a picture；Photo data program is obtained, and compiles and obtains .hex files.(2) AVR is used Studio is respectively by .hex file downloads to single-chip microcomputer U1 and U2.(3) single-chip microcomputer U2 serial ports is connected with PC, opens serial ports and adjust Assistant, baud rate 9600bit/s, check bit NONE, data bit 8, stop position 1 are tried, and is shown with hexadecimal.Press again The reset key of single-chip microcomputer, cross 5s, it is possible to data are received on COM Debug Assistant, this data is saved, are named, most Operation convert.exe can be obtained by .GIF image files afterwards.
