Commands

colorCONTROL MFA-5

6.2.2.3 General Check of Pulsed LEDs

capturepwm

Measures and saves the color and intensity of pulsed (PWM) LEDs.

Command

Description

Received

Example

Note

capturepwm Start PWM color, intensity

check

capturepwm

Check of all color-

CONTROL MFA-5

and sensors with

current settings.

PWM LED = Pulse Width Modulated LED
This command tells the colorCONTROL MFA-5 to check and save the colors and intensity of all connected

LEDs.
Thereby, a default setting is used which is sufficient for most LEDs.
However, it is recommended to set the preselection manually to achieve better results for different LEDs, see

Chap.
