I2C forbidded address

[mikemoy]

It is nice to know the spec and follow it unless you have a decent reason not to.

The spec is pointless if the manuf. does not obey it. It all comes down the what is said in the data sheet, not the spec.

And it is reasonable that an i2c scanner code would skip reserved addresses.

"reserved addresses" ??? Reserved for what? That means something is there on the bus. You dont reserve things that are not there.

The table says what they are reserved for, special functions. The Cypress part has a default address of 0 but it is meant to be changed during factory programming. It would be interesting to know if other i2c devices have an address of 0 especially if they are non-programmable.

This is strange to me too, to have a device with that default address. Anyway, while I am waiting for the boards to arrive, I don't know if I should expect some collisions on the I2C bus since I have 6 slaves. Maybe the CY8C20110 is made to be alone on the bus...
