Hello,

Today I tested the PIC12F675 receiver after your "GENERICAL RECEIVER PT2262 – 12F675" and I am impressed that it works. The outputs are latches, please if it is possible to modify the outputs to be momentary, I don't know assembler and I don't know how to modify, please.

Hi Samtinos
As soon as I have time I will assemble the circuit again to test it with 'pulse mode' or 'momentary mode'.

Hello Samtinos 
I already had the 'pulse' (momentary) mode version ready and added it to the article to be downloaded.

Hi,

Thank you very much for the answer and for changing the outputs in pulse mode. I will test the receiver today.

Hello,
I tested it and it works well, but there are three small problems.
1. Without memorizing the remote control when powering up the board, the LED in pin 2 (GP5) lights up sometimes.
2. The delete function does not work.
3. During the learning function for the first learned channel, the pin 7 LED turns off, press it a second time and memorize the second channel on the remote control, the learning LED stays on, I also memorize channel 3 and the learning LED turns off, press it a third time and memorize channel 4 and the learning LED stays on and lasts about 7 seconds and goes out. For the latch outputs the behavior is the same.

Hi,

The PT2272 has two pins (15-16) intended for a resistor for the oscillator. What frequency does the receiver "GENÉRICO PT2262 – 12F675" oscillate in order to do the decoding correctly?

Hi Samtinos

Resistor 4M7

Try to use this hex:  rx_pt2262_gen_x_pulso
