VT: channel output valid signal, the microcontroller can be used as an interrupt signal
3. the working mode
You can select different modes of operation with"M4 M3 M2 M1 M0" pad in the delay mode to adjust the delay time through an adjustable resistor.
In delay mode, the rotary variable resistor can adjust the delay time. Increase the time counterclockwise rotation, and clockwise rotation to shorten the time. Adjustable resistor is a precision resistor, adjust the time with a Phillips screwdriver to gently rotate (do not use excessive force)
Working Mode Description:
Non-locking: Press the remote control button, the IO port outputs high. Release the remote control button, IO port outputs low.
Self-locking: Press the remote control button, the IO port outputs high. Press the remote control button again, IO port outputs low.
Interlock: Press the remote control button D0, D0 IO port outputs high, other IO ports outputs low; remote control button is pressed D1, D1 IO port outputs high, other IO ports output low and so on.
Delay: Under Delay mode, there is a delay 0/1/2/3/4 five sub-patterns, by adjusting the variable resistor IO port high duration
4, the adapter remote control (learning remote control)
In normal operation mode, LED (D1) will be lit, when receiving a valid remote control (EV1527 / PT2262) key value, LED will flash.
Clean code: hold the button to press.LED offs, keep pressing about 8 seconds until LED lights. At that time, clean code completion (Note: After the implementation of clean code, previous remote controls do not exist.
Adaptation (learning):
Step 1 (into the learning mode):trigger the key button, LED offs;
Step 2 (adapter channel 1): press the first button of remote control and then, LED offs after flashes for four times. This time means that it had learned the value of the first button
Step 3 (Adaptation Channel 2): Press the second remote control, LED offs after flashes 4 times, This time means that it had learned the value of the second button
Step 4 (adapter Channel 3): Then press the remote's third button, LED offs after flashes 4 times, This time means that it had learned the value of the third button
Step 5 (Adaptation Channel 4): Then press the remote control's fourth button, LED lights after flashes 4 times, This time means that it had learned the value of the fourth button.
NOTE: The process must be completed within 15 seconds
