a problem RF Signal with PULSIN

[Ioannis]

What is your transmited signal? What baud rate? How many bits?

Are you transmiting with some kind of Serout like command?

I solved it by TMR0 and I changed the RF pin. The pin was PortA.0 but I cannot get any signals from here. Then I decided to chage port and the new port was PortC.5. And the result was Ok. I could read signals. Why I didnt read any signals from PortA.0 ? (16F876) Does anybody has an idea? Thank you so much again.

PORTA on the F876 is configured to A/D inputs by default on power-up due to
the default value in the ADCON1 register on power-up.

ADCON1 = 7 ' configures A/D pins as digital I/O.

Also, PORTC.5 is a schmitt trigger input. RA0 is TTL.
