API

setStatusLight

函数原型:

void setStatusLight(const uint8_t& r, const uint8_t& g, const uint8_t& b);

功能说明:

• 进行RGB LED灯颜色设置。需注意，RGB LED由IO拓展芯片引脚驱动，故无法进行亮度调节 。

传入参数:

• const uint8_t& r：
  • 1: 点亮红灯
  • 0: 熄灭红灯
• const uint8_t& g：
  • 1: 点亮绿灯
  • 0: 熄灭绿灯
• const uint8_t& b：
  • 1: 点亮蓝灯
  • 0: 熄灭蓝灯

返回值:

• null
