I2C Communication with SMI Protocol-A
This document is a reference for a possible coding method to achieve pressure, temperature, and status for SMI part readings using I²C. This SMI Protocol-A is used on but not limited to SMI parts SM9541, SM9543, SM3041, etc. Please check part data sheet for the correct SMI I²C protocol used. For more general information on how to interface using the I²C protocol please refer to http://en.wikipedia.org/wiki/I%C2%B2C. Note that the current example serves as only a “pseudo-code” meaning that it will not work by itself, needs additional work, and is only meant for guidance purposes. Therefore this example may look different depending on which coding language is used.
