    Default VEML6040 I2C sensor problem

    Hello,

    Wondering if anyone has used the Vishay VEML6040 color sensor with I2C interface. I am having trouble reading it and think it might be related to the fact that you need to send a command code byte followed by a read without a stop bit after the command code byte. Here is the format.

    StartBit-SlaveAddress-WriteBit-Ack-CommandByte-Ack-StartBit-SlaveAddress-ReadBit-Ack-DataByteL-Ack-DataByteH-Ack-StopBit

    Is this possible to do with the built in I2C commands?

    Let me try asking it this way...

    Will the built in I2C commands allow for a device which needs a repeated start condition in order to read?
