That is was the way I worked until now.

But I can only do:

1) Master write: as many bytes as I want BUT I can't get the interrupt on the stop bit

Hi,
I have a discussion with my elettoronic-designer and I need your help.

In a previous post ("Does I2c has a minimun clock freq") I asked something about I2C and in the replies Ttelmah and a ...

I posted a new topic today because I can't get the stop bit, but now it seems to work quite well: there was a problem with a resistance on the circuit: incrementig that the PIC is now able to force do ...

Well: I'm quite new to PIC programming. Onestly I don't know what SMBus is... may I take a look to the PIC Datasheet ?

For the open collectors I'm goint to print this topic and bring it to my eletr ...

Thank you Ttelmah; your suggestion are very interesting. I'm only a developer and my understand about elettronics is very poor, but this evening (Italy time) I'll meet who made the circuit and i'll ta ...
