RGB color output and a separate white output.
void set_max_refresh_rate(uint32_t interval_us)
Set a maximum refresh rate in µs as some lights do not like being updated too often.
Definition: led_strip.h:46
White output only (use only if the light also has another color mode such as RGB).
This class is used to represent the capabilities of a light.
Definition: light_traits.h:11
Implementation of SPI Controller mode.
Definition: a01nyub.cpp:7
Color can be controlled using RGB format (includes a brightness control for the color).
