Two P8X32A and I2C communication

megaionstorm

How can two P8X32A communicate with another through i2c ?

Every P8X32A has a own EPROM and both EPROMS has the same i2c address !

I2C on the prop is not relegated to any pin. You can use any pin pair.

Try this simple object for starters:

You'd have to write some I2C slave code. While not hard to do, I don't think anybody has done that yet: there isn't really much need when you can just use a full duplex asynchronous link for the data.

Here is an old thread that discusses I2C Slave with the Propeller http://forums.parallax.com/showthread.php/102839-I2C-Slave?highlight=I2C*
