 		 #109500 - question, language and added info
Responding to: ???'s previous message
First: I repeat Kalpaks question: Any reason not to use its hardware I2C

Not a criticism, just clarification
1) hardware I2C bus what it has is a hardware interface the "bus" is outside the chip.
2) SILabs does not have an IIC interface it has a SMB interface. This, however is no problem, basically the only difference is that the SMB has a time out which the IIC does not have. I have yet to find ANY problem with using SMB intefaces for IIC.


The IIC code generated by CodeArchitect for LPC932, free from http://www.esacademy.com can be modified to fit SILabs derivatives (forget the f3xx deviates) in less than 1/2 hour. I find that much easier to "modify to fit" than the SILabs appnote "Serial Communication with the SMBus AN113" You choose what fit you the best.
