starting with I2C

I have two 2041 lcd and I want to put it on cascade with my PC using the rs232 port.

I have read a lot of messages and the faq of the LCD but I didn't found how I can use my rs-232 port to use it with I2C and the necessary hardware interface.

Do you have any code example or any product to do this.

What do I need?

really thanks

Adri

I2C and RS232 are two totally different languages... you cannot use a RS232 port to talk I2C. I have seen on the net making a Parallel port talk I2C before. It required some hardware and software.

but is there any available RS-232 == I2C conversor?

Honestly I do not know... I have never looked for one and I do not know of one. All I have seen are I2C expansion cards.

It's like a Serial port or Fire Wire expansion card, it just gives you a number of I2C ports...
