Re: I2C with 15V @ Arduino?

Posted: 27 Apr 2013 03:15 AM PDT

Yeah 3.3 V thats what I'm thinking . But still getting the gripes about the 15V.

But thinking about it logical/rational I'm going to support hte voltage pin with 15V. And will try to read 3.3V I²C through Level Converter with my arduino.

Thanks to you ...

You are right, I confused the word current with voltage, I am sorry. Please replace every "current" in my posting with "voltage".

Re: I2C with 15V @ Arduino?

You have a normal 3.3V I2C bus.

If the I2C bus is not busy, the pull-up resistors pull the voltage to a high level. Since you measure 3.3V, it is a 3.3V I2C bus.

The I2C bus should not be used with a twisted pair cable and the maximum cable length is a...

It would be VERY unusual to have a 15V I2C link, in fact I've never heard of such a thing nor can I remember ever seeing a chip that would handle such a high voltage. Not saying all this doesn't exist, but can you verify that t...

Ricorda di scrivere il codice con gli appositi tag CODE: pulsante # nell'editor, sopra le faccine.

Se stai provando con singoli led e non con i driver, ricordati la resistenza per ciascuno.

Re: Digital compass module recommendation request: CMPS03 v. HMC6352

It is not a dumb question, many posts have been written about the I2C levels.

The HMC6352 has a range up to 5V. That makes it easy to connect to an Arduino.

Most sensors operate at 3.3V.
The Arduino Uno has a 3.3V output pin to supply the 3.3V for thos...
