MATLAB: Control brightness of LED with PWM using TI C2000

Developers Kit for Texas Instruments DSPelectric_motor_controlpower_conversion_controlpower_electronics_controlpwm

Hi there,
I am quiet new on Simulink and I am trying to familiarise myself with PWM. Does anyone know how to control the brightness of an LED with PWM using a Texas Instruments Delfino Microcontroller? Thank you in advance.

Hello Michali,
The PWM block in simulink can be used for this purpose.
The input for this block can be any number from 0-255, depending on how bright you want the LED to glow.
0 being the least bright, and 255 , the maximum brightness.
The pin in the PWM block is hte pin where the LED is connected to in yout Microcontroller.
Remember to connect a resistor in serieis with the LED.
