【正文】 add model multilevel 4. for the 000H unit add data bytes, 5. RESET to increase the 12V activation programming, 6. jump to a one byte programming or encryption, 7. calibration has been programming, data from 12V to RESET logic level H and set for the correct level, and can output data in P1 mouth, the next addresses) in the unit XTAL1 byte programming, a pulse, make address counter add 1, in mouth add programming data P1. Repeat step 18 plete the whole 2KB programming. Electricity is XTAL1 Settings: in order to L RESET, and float empty other I/O foot, close the VCC power. (3) programming and calibration circuit figure c, d. Figure c programming circuit Figure d calibration circuit Explanation: (1) during programming instructions to be low RDY/BSY, (2) single erasing the PROG 10ms need, (3) internal EEPROM address counter on the rising edge RESET, and 000H RESET to XTAL1 by foot pulses are executed. Along with the rapid development of science and technology, human society has undergone earthshaking changes. Make our life more colorful. In these changes, the remote control technology has been widely permeates TV, aerospace, military, sports and other production, all aspects of life. From the broad sense, all equipped with electric lootive facility or electrical switches, if feel some necessary, can consider to improve existing with remote control device, the operation fixed switch to realize the remote operation of the original equipment, stop, the variable, etc. Function. switch, for example, can be used to control the electric control switch the light switch, We design the infrared remote control system to realize the opponent switch quantity control. Infrared remote characteristic is not influence the surrounding environment and does not interfere with other electric equipment. Due to its cannot perate walls, so the room can use mon household appliance of remote control without mutual interference, Circuit testing is simple, as long as given circuit connection, generally does not need any missioning can work, Decoding easily, can undertake multiple remote control. 。 12 hundredth kHz 38kHz hundredth 379,000. Some remote control system adopts 36kHz, 56kHz, etc, general 40kHz launched by the crystals of oscillation frequency to decide. Infrared remote characteristic is not influence the surrounding environment and does not interfere with other electric equipment. Due to its cannot perate walls, so the room can use mon household appliance of remote control without mutual interference, Circuit testing is simple, as long as given circuit connection, generally does not need any missioning can work, Decoding easily, can undertake multiple remote control. Because each manufacturer produces a great deal of infrared remote applicationspecific integrated circuit, when need press diagram suo ji. Therefore, the infrared remote now in household appliances, indoor close (less than 10 meters) in the remote control is widely used. Multiple infrared remote control system of infrared emission control buttons, there are many parts general representative of different control function. When pressed a button, correspondingly in the receiver with different output. Receiving the output state can be roughly divided into pulse, level, selflocking and interlock, data five forms. The pulse output is according to launch when the button, the receiver output terminals output corresponding effective, a pulse width 100ms in general. Level refers to the output launch press button, the receiver output corresponding output level , effective transmit to loosen the receiver level disappears. This effective pulse and effective, may be of high level is low, and may also depend on the output corresponding static state, such as feet for low, static high for effective, As for the static, low high effective. In most cases, high for effective. Since the lock refers to launch the output of each time you press the button, a receiver output corresponding change, namely originally a state for high level into a low level, originally for low level into high level. The output power switch and mute as control etc. Sometimes also called the output form for invert. The interlock refers to multiple outputs each output, at the same time only one output. The TV sets of this case is selected, the other is like
