PWM

Speedgoat provides PWM (Pulse Width Modulation) measurement and simulation functionality. You can implement required functionality and channel count on the Configurable I/O Module. 

This code module provides support for:

PWM generation: This allows a PWM device, e.g. rotary encoder or linear position sensor, to be generated.
Key functionalities supported by the PWM generation code module include:

  • Symmetric, asymmetric, single-phase, and multi-phase PWM generation
  • Dead band compensation
  • Frequency-modulated pulse trains

 

PWM Capture: This allows a PWM device, e.g. rotary encoder or linear position sensor, to be measured.

The following pulse train durations or periods can be measured:

  • Duration of high pulse
  • Duration of low pulse
  • Period between low to high transitions
  • Period between high to low transitions

The outputs of the Simulink driver block are:

  • High duration - total time the input is high between the last two triggers
  • Low duration - total time the input is low between the last two triggers
  • Period - time between the last two triggers
