The Si1133/5x Optical Sensor EXP board now has an example project running on EFM32PG12 MCU to demonstrate our latest Si1153 for proximity/ambient light sensing and Si1133 for UV sensing. The example project will require an EFM32™ Pearl Gecko PG12 Starter Kit(SLSTK3402A) to plug in the Si1133/5x Optical Sensor EXP board through the 20pin expansion header.
The source code of the example project is provided in the attachment.
We also have a nice video describing all the features included in the demo. Please make sure to check it out before getting started.
