I can't lay my hand on the datasheet at present, but most I2C devices have a pin (pins) for selecting alternate addresses, but this is a function of the hardware. The alternative on some devices is two versions of the same device with but with different addresses, so that replacing a device, the correct version must be used. So what is the hardware setup? -- Lester Caine ----------------------------- L.S.Caine Electronic Services _______________________________________________ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert
