PCA9555: I2C example code

Part Number: PCA9555
Other Parts Discussed in Thread: TCA9555

Customer ask if we have I2C example code for PCA9555? It is best base on MSP430. I try search in TI.com and do not find any design reference for PCA9555 , so I  double confirm in here, thanks.

    Hey Terry,

    ----------------------------------------------------------------------------------------------------------------------

    I would like to suggest changing from PCA9555 to TCA9555 as it solves some of the bugs from the PCA family, is more cost competitive, and is pin to pin with the PCA version.

    We do not typically supply example code for our devices.

    "It is best base on MSP430"

    We do not have this but I did generate one in Arduino.

    If this is not sufficient, you could make a thread in the MSP430 forums and request for code. They may be able to provide you with code.
