  1. Hi, does anyone have experience with the OPT3001 sensor using custom hardware or interfacing to the msp430 launchpad? I have a sensor on the TI opt3001EVM daughter board, with the SDA pins and SCL pins connected to vdd via 10k resistor, for a msp430fr5969 wolverine launchpad - I am able to read the data from the sensor, but every time I rapidly change a test light source (flash a light on the sensor, or put my hand to cover it), I get a corrupted reading (it reads FFxx). I currently have it set to poll at 100ms, and at autoscale with no mask. The autoscale does work, it's just during transition periods the first byte is read 0xFF. The sensor works fine using the TI OPT3001EVM module. Thanks for any insight or help! The configuration register is set to the following value - 0b1100010000010000 - Automatic full scale setting mode - 100ms conversion time - Continuous conversion mode - Mask field disabled - latched mode enabled
