The DotBot uses a TLC5973D 1-wire RGB LED driver. the SPIM peripheral is used to generate an arbitrary serial sequence that the Driver will recognize.

void db_rgbled_set(uint8_t red, uint8_t green, uint8_t blue)

Set the color to display in the RGB LED.

Assembles the 1-wire encoded command to change the color of the RGB led. Afterward, an SPI transfer is necessary to actually update the LED color.

Parameters:

• red – [in] red value of the led color [0 - 255]

• green – [in] green value of the led color [0 - 255]

• blue – [in] blue value of the led color [0 - 255]
