Liang,

As indicated in the Patterns/Frame timing diagram - the patterns will be displayed in R,G and B illumination sequentially based on the exposure time settings.

Regards,

Mayank

Hello User,

There is not a way to change the whitepoint while using this feature.

An alternative would be to replace the red LED with a white one. TI has a red only FW image in the Pico FW Selector Tool. TI has tested and validated this EVM with only RGB LEDs.

Regards,

John
