[SOLVED] PIC is not working under strange condition

[bigdogguru]

I had done a 433 MHz RF module based remote control. There was no issue of encoding or decoding data. Here is the video of it.

Perhaps not if the TX and RX modules are within inches of each other.

However, if there is any significant distance between the pair and other RF emissions in the area, I can assure you there will be issues.

As noted by Korawy:

im using 434 MHz ASK module and it's similar to the picture, UART has a problem that will not make RF operate at a long distances.

BigDog... u r right about the RF module, that what i have done in the transmitter code, where the "1" pulse consists of number of pulses (if "1" period is 1000us, i have to transmit a set of pulses of frequency ~38KHz for a duration of 1000us), that's also for the "0" pulse but with a little time period.

I will check if it works for long distance or not.

jayanth.. the problem is not in the library, i know that i have to change(change) to set, im saying about testing the circuit in real, The Lights of the LEDs are going high(but their state is "0"), and it's not a total high, it's something of 2 or 3v.

About RF there's no any problem for me, it works fine.

Post your Circuit.

 

[Korawy]

This is half the circuit..

The power of BC547 is 5v

The Lights of the LEDs are going high(but their state is "0"), and it's not a total high, it's something of 2 or 3v.

Where are the LEDs in the Circuit. What exactly is the problem. Zip and post Proteus file.

View attachment PWM@Encoder.rar

The LED is parallel to the relay.

 

[jayanth.devarayanadurga]

Is RA3 and RA5 your encoder inputs?

 

[Korawy]

No, RA4 and RC0.
