Serial Communication using 12F629

[Ron Marcus]

[QUOTE=charudatt]Hello Ron,

I think that is the case !. Because , its not that I am not getting anything out, but just that its Garbage.

Can you suggest how to use the INTOSC Config in the code.

An easier way to do it, is to find out if the rate is too fast or too slow. This can be done with a frequency meter. If it is, for arguement sake, too fast, I would do a for next loop incrementing the serin2 baud rate number by one, until the character or word coming out of the pin is the right one.

Example: For A = 1 to 100
Serout2 pin,32768 + A,[dec A, "test"]
Next A

On the receive side, you should get the right number and right date when the baud rate is correct. Just add the number ti the baud number and all will be right with the world. If you don't have access to a meter, then try it above and below the proper number.

First, Make sure u have a small Cap on the power supply! (.1uF) . If that dose not fix it then ,

Add this after your "fuses"
DEFINE OSCCAL_1K 1

Change this:
SEROUT2 SER, 16780,["TEST" , 10] '2400 BAUD RATE
To
SerOut GPIO.4,N2400,["Test" ,10]

Kattronics:

I already tried what you said, with the DEFINE OSCCAL_1K 1 the PIC goes bonkers. Not sure what is wrong with it.

I also tried the SerOut GPIO.4,N2400,["Test" ,10] but no luck,

I think I would go with Ron's suggestion and try it out.

Nevertheless I succeeded in decoding Sony IR codes using the PIC ,which was my end intentions anyway, but just for the sake of testing out serial communication , I would compelete this experiment and post my results.

Thank you all.
