PWM Capture FPGA Code Module

Configurable PWM Capture support with Simulink driver block

This FPGA code module provides PWM capture support. 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 how 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

A PWM generation FPGA code module is also available.
