JUST THANK YOU SO MUCH , at least I've got an answer and I will remember that declaring a pointer doesn't allocate any memory!

Once again Many thanks PCM Programmer to take the time to answer to s ...

Hi all
A 2 days Nightmare !
Chip is a 16f767, compiler 4.104
I declare a GLOBAL pointer:
int8 *FwdDev=0;
and a variable:
int8 d;

later then when I do:

(*FwdDev) = d;
Fprintf(HF,& ...

I guess you're right! I'll let you know.

Hi
did you use the 12F629 header (equipped with the 12F629-ICD) or directly the 12F629

So I would but I've been trying and trying for the last 2 days!
I guess something wrong in the config ??
did you say you 've used the 12F675 header connected to ICD3 with sucess ?*

Happy to find someone who tried that 12F675 header. So did I
But so far no joy! a very simple program (led blinking) in asm works but the same in C doesn't !

Has any one ever have success with tha ...

I was in fact thinking of an interface I2C/ RS 232 because my project uses already an I2C bus and I'd like to add a HF transceiver, but the one I'd like to use uses TTL RS232. It would be simplier to ...

In fact none of these are able to act as a slave on a device without hardware!I ve got to take another PIC

I just found this project of I2C to RS232 interface
. Coded in assembler : too hard for me !I thought It would be possible with C, don't you ?http://www.gedanken.demon.co.uk/rs232-converters/i2c.html

to complete : Is it possible to establish I2C communication between 2 non equipped I2C devices such as the 12F629 ? one master and one (may be more but at least one ) slave that would be able to respo ...

Hi Sorry cause I originally post in the code library forum;
my question is : Is it possible to built a software I2C slave on a chip that doesn't have any hardware I2C; From the forum, the slave code ...
