RF and PIC basic
Hello dear friends.
I want to make a new project but, have some unknown.
I have a transmitter module 433,92 Mhz rf module and PT2262 encoder I send any data and adress word. than I want to use rf receiwer modules 433,92 and PIC16F628 for decoding.
So how can I read from PT2262 IC's datas whith PIC16F628
Thanks for all

If you use an ENCODER you will need a DECODER. (normally)

yes it is true ..and I know. but I dont want to use any decoder Ic. because my project is working with PIC16F628 . so I want to write decoder code in my PIC16F628.
thanks.

I do not remember exactly, but I think dhouston or Bruce had a way to do this. Might have been for a Holtec Encoder though.
Found it.

The datasheet for the PT2262 doesn't provide any description of the communication protocol so, for starters, you will need to capture a few (different) codes and analyze them. This page shows how. http://davehouston.net/learn.htm

I found another datasheet that does describe the protocol used by this chip. While the specifics for a "1", "0", and "F" differ from Holtek, the overall approach is very similar to the HT640. A bit period depends on the encoder oscillator frequency (set by an external resistor) you still need to capture some codes to determine the bit period. And there are some encoder pins that can be used either in the address or in the data so you'll need to determine that, also. Then you should be able to adapt Bruce's HT640 code to work with the PT2260.
