  • I’m surprised that no one has mentioned this, but from the I2C module description in the datasheet (5.10.1):

    The MMA8452Q expects repeated STARTs to be used to randomly read from specific registers.

    Unfortunately it seems that BCM2835 (RaspberryPi’s SoC) does not support repeated START sequence. This means that this accelerometer is not compatible with the I²C bus on RaspberryPi.

    More information in the link here.

No public wish lists :(
