The STSW-IMG301 is a graphical user interface (GUI) for Windows 7 and Windows 10. The GUI controls the P-NUCLEO-6283A1 pack which consists of the X‑NUCLEO‑6283A1 expansion board connected to the STM32F401RE Nucleo board.
The VD6283 (1.83 x 1.0 x 0.55 mm) is the smallest 6-channel, ambient light sensor (ALS) on the market. Light measurement is fast and accurate thanks to an individual ADC and readout circuitry for each color channel (Red, Green, Blue, IR, Clear and Visible). The VD6283 uses hybrid color filters with precise responses allowing accurate computation of the correlated color temperature (CCT) and Lux information. The VD6283 can be used for display brightness management or scene light correction. Additionally, the VD6283 can extract light flickering frequencies from 100 Hz to 2 kHz, including LED square signals.
To install the STSW-IMG301 GUI, refer to the X-NUCLEO-6283A1 quick-start guide.
