The x-IMU RGB LEDs connects directly to the auxiliary port and can be driven by PWM to create any colour light. It is a simple solution to provide real-time feedback to a user from the host software. The module consists of a driver IC and 3 high brightness, defused lens RGB (Red, Green, Blue) LEDs. The module is powered by the x-IMU and the RGB channels are controlled by the auxiliary port channels AX0, AX2, and AX4. The RGB LEDs interface to the auxiliary port while in either digital I/O mode or PWM output mode. The auxiliary port can be used in digital I/O mode to switch each RGB channel turned on or off to create up to 7 different colours. The auxiliary port's PWM mode can be used to control the brightness of each RGB channel independently to create millions of different colours. See the x-IMU RGB LEDs schematic for further technical information. |
