RC5 receiver with PIC18Fxx

[patrick schoon]

I'm working on a project with a PIC18F66J50. Till now all is working fine with FC5.
Now i'm try to implement a RC5 receiver but what ever i experiment thare is no reacting result from the controler.
I did some test on Ebloks with varius other controlers and that works as it should be.
I even only put in the Matrix RC5 receiver example only but no results. also different clock experiments but nothing..
Are thare users who experiance the same problems like me?

Has any one a RC5 receiver working on a PIC18F?

Hi Patrick,
Can you please post the program you have tried so that we can have a look what's going wrong?

Dear Enamul,

Thanks for the effort to look over the programm.
As told it's a copy of the Matrix FC5 RC5 reader example, exept i changed the display for RS232 output.
I tested it on a PIC16F877A and all is working fine..
The programm is starting up until the Startup mesage on the RS232.

Hi Patrick

I dont have the device you are using, but Ive attched a simple test program I wrote to use the eblock for testing RC5 remote controllers

I use Timer rather than interupt and have it connected to Port C bit 6 (16F877A)
(I know im using a 4 line display but that should not be much of a problem to alter)
Also have you checked the jumpers on the e-block are set correctly for your device etc.

Hi John,
I guess you forgot to attach the file.

Thanks,Enamul
Its been a long day

John,

Did test your small programm you attached.
No results with this.

Did some more tests between a working MCU and the 18F66J50.
I checked both c codes and think thare are differences in seting up the timer-0

For now no time left to invest.

Thanks,

Patrick

Hi Patrick

Yes, the flowchart I attached works ok on my hardware

[patrick schoon]

The problem is solved.

I managed to modify the original PIC16 code to PIC18.

Main problems are in differences between the P16 and P18 timer declarations.

The attached FC5 code is optimized for PIC18F with 24MHz clock.

Cheers.
