decoder (by Ronildo Freitas)
Good day, I would help, because I have a remote control electronic gate that uses the encoder (HT6P20D) and has four (4) buttons, I would like him to decode the signal using the PIC16F876.
thank you Ronildo. From Brasil.

how are you getting the signal to the PIC?

I'm getting the signal via rf receiver,
I used another encoder / decoder (MC145026 and mc145027), I got them as a (MC145026) encoded and decoded the other, but now would like to do the decoding right in pic, do not know if you can, now I have that control with the ci ht6p20d I transmit it via the signal transmitter-receiver rf, but do not know how to decode the signal it.

The first thing i would do is connect the PIC through I think atmega32 would be better as it is faster and the program might need to scan fast.
connect the receive signal to the micro and count the clocks (sent the total out the uart) and see if the number of received pulse counted in the micro matches what the datasheet of the transmitter says it is sending, maybe setup a counter on the transmitter to count pulse sent so you can compare the resolute, as there is no point trying to write code that is never going to work because it is not receiving the full signel. regards David

Dear David, thanks for the help, I think I need a little help, I think my skills are not enough to understand his explanations, I apologize for my ignorance ..

I need to know how the rf signal gets to the PIC.
What is the RF front end? does it produce A filtered digital signal? Regards David.

Hello David, excuse the delay in responding, I was trying to understand better what I need, so to better formulate my question.
I read something about it, and I think I need to use a UART microcontroller to decode the signal from the remote control. If you have something, a link or somewhere I can learn more about, or even you can help me .. What I know is that the signal is in the form of pulses (square wave), but then on it I'm trying to understand ... I thank the help .. Below is attached to the waveform to the microcontroller generates ci .. Ronildo
