Encoding and Decoding
The popular link is like this: MCU -gt; Encoder -gt; Transmitter ------ Receiver -gt; Decoder -gt; MCU,
PT2262(Encoder) and PT2272(Decoder) are optional, their existence is to 1)avoid confusing when multiple RF links in range 2) isolate disturbance. You can integrate the encoding and decoding work to the MCUs on both side. Whenever there is no 315Mhz devices around, you may use it as direct cable connection.
To setup a PT2272 and PT2262 link, you would need to set PT2262 by a little soldering:
And setup the corresponding pins on PT2272:
Please refer to the simple drawing for the 315Mhz RF link. On the transimitter side, You would need to supply 3-5VDC to the +12V pin,(Caution: the 12v is an error silk screen on PCB, never give it more than 5V, and set TE high(5V) to enable transmission. On the receiver side, you may use +5VDC(aka VCC) for power and read the output from D0~D3. TV will indicate thenever there is changed data incoming.
