setStatusLight
Function Prototype:
void setStatusLight(const uint8_t& r, const uint8_t& g, const uint8_t& b);Function Description:
- Sets the RGB LED color. Note that the RGB LED is driven by the IO expansion chip's pins, so brightness adjustment is not supported.
Parameters:
- const uint8_t& r:
- 1: Turn on the red light
- 0: Turn off the red light
- const uint8_t& g:
- 1: Turn on the green light
- 0: Turn off the green light
- const uint8_t& b:
- 1: Turn on the blue light
- 0: Turn off the blue light
Return Value:
- null
