Main program: (1) system initialization: counter T0 arranges, LCDs 12864 liquid crystal initialization, external interrupt setting;
(2) open interrupt INT 0 trailing edge effective;
(3) interrupt detecting: wait for infrared triggering, return to step (2)
INT0 interrupt service routine: (1) is closed INT0 and interrupted
(2) open 800us Interruption
(3) initialization reception area variable
(4) exit interruption
T0 interrupt service routine: (1) is written into TH0TL0
(2) read remote control reception head status
(3) receive, go to step (7)
(4) infrared decoding
(5) LCd code displaying
(6) reopening INT0 interrupts
(7) exit interruption
It should be noted that: 1, serial ports stealing, after serial ports is opened, 4 and the 7 pin level of RS232 can change, produce the voltage higher than 10V, by rectifier diode D1 and D2, after employing resistance R 2 dividing potential drops, obtain the voltage stabilizing (D3 realizes by voltage stabilizing didoe) of 5.1V, add the maximum 20mA of Power supply electric current, substantially meet power reguirements; 2, serial communication, the serial ports of single-chip microcomputer generally uses TTL positive logic level standard, and its logical one level is 5V, logical zero level is 0V, be the negative logic level standard of RS232C and computer serial port uses, its logical one level is-3V--12V that logical zero level is+3V-+12V.Both level ranges fall far short, so need to use level shifting circuit while connection, in general business-like finished product can be used MAX232, RS232, Transistor-Transistor Logic level converter ic that DS275 etc. are special, be 9600 because system adopts baud rate, less demanding, therefore the level shifting circuit that uses low-power transistor to build according to experience is saved design cost.
Fig. 6 is the total program flow diagram of the system of touch screen remote controller of the present invention.First initialize routine, judges whether touch-screen has key to press.In the time having key to press, the outer interrupt request singal (Low level effective) of generation, through eight input nand gates and the non-P3.2 end of delivering to behind the door, enters CPU and interrupts processing, and lights button indicator light simultaneously.The remote control coding signal that system produces is held and is sent by P3.5, through amplify rear drive transmitting tube launch judged be which key press and which kind of state in movement after, program is just carried out the transmitting of remote control mode in strict accordance with corresponding remote control coding modes, until finish.
In sum, a kind of touch screen remote controller of the present invention, by control circuit, transmitting and transmitting indicating lamp circuit, receiving circuit, display screen and surface acoustic wave touch keyboard, realize the object of carrying out remote control electrical appliance by touch-screen, solve in prior art button easy to failure, and button is difficult for the problem of identification, simultaneously the present invention adopts infrared dash receiver with liquid crystal display to realize preview function, convenient for users to use.
Above-described embodiment is illustrative principle of the present invention and effect thereof only, but not for limiting the present invention.Any those skilled in the art all can, under spirit of the present invention and category, modify and change above-described embodiment.Therefore, the scope of the present invention, should be as listed in claims.
