Description: When the detect subroutine is invoked, it initially waits for a start bit. The duration of the low segment of the first start bit is measured. If the low pulse of the first start bit exceeds 1.020 ms or is shorter than 800 µs, the routine returns an error indication. The measurement of the start bit is utilized to calculate two reference times, ref1 and ref2, which are employed when sampling the data line. The program utilizes the edge in the middle of the TSOP4836 from Vishay Semiconductors, which is part of the TSOP48XX series. After the infrared signal is demodulated, the protocol is decoded by IC1, which subsequently activates or deactivates the appropriate channel. The output of IC1 toggles each time the transmitter sends the same command to the receiver. The output drive circuit may be modified to accommodate different requirements.

The described circuit operates by detecting a start bit from a data stream, which is critical for synchronizing communication between the transmitter and receiver. The detect subroutine is designed to monitor the timing of the incoming signal, specifically the low pulse duration of the start bit. This timing is crucial as it establishes reference points (ref1 and ref2) for subsequent data sampling, ensuring accurate interpretation of the incoming data.

The TSOP4836 infrared receiver module is employed to demodulate the infrared signals. This component is sensitive to modulated IR signals and is capable of filtering out ambient light interference, providing a clean output signal for further processing. The demodulated signal is then fed into IC1, which is responsible for decoding the specific protocol being used. IC1 interprets the incoming data stream and determines which channel should be activated or deactivated based on the received commands.

The toggling output of IC1 indicates successful command reception, allowing the system to react appropriately to repeated commands from the transmitter. This feature is essential for applications requiring reliable communication and control, such as remote control systems or wireless data transmission.

The output drive circuit connected to IC1 can be tailored to suit various applications, whether it requires higher current capabilities for driving larger loads or specific voltage levels for interfacing with different components. This flexibility allows the circuit to be adapted for a wide range of devices and use cases, enhancing its versatility in electronic design.When the detect subroutine is called, it first waits for a start bit. The length of the low part of the first start bit is measured. If the low pulse of first start bit is longer than 1. 020 ms or less then 800 uS the routine returns indicating error or no The measurement of the start bit is used to calculate two reference times, ref1 and ref2, whi ch are used when sampling the data line. The program uses the edge in the middle of use TSOP4836 from Vishay Semiconductors that is one of TSOP48XX series. After IR demodulated it was decoded the protocal by IC1 then turn on/off appropiate channel. The out out of IC1 is toggle every time when Tx send the same command to Rx.
