TMS320F2837xD Microcontroller Workshop - Control Peripherals 7 - 1
Control Peripherals
Introduction
The C2000 high-performance control peripherals are an integral component for all digital control
systems, and within the F2837xD these peripherals are common between the two CPU
subsystems. After reset they are connected to the CPU1 subsystem, and a series of CPU Select
registers are used to configure each peripheral individually to be either controlled CPU1
subsystem or CPU2 subsystem. This module starts with a review of pulse width modulation
(PWM) and then explains how the ePWM is used for generating PWM waveforms. Also, the use
of the eCAP and the eQEP will be discussed.
Module Objectives
Module Objectives
Pulse Width Modulation (PWM) review
Generate a PWM waveform with the
Pulse Width Modulator Module (ePWM)
Use the Capture Module (eCAP) to
measure the width of a waveform
Explain the function of Quadrature
Encoder Pulse Module (eQEP)
Note: Different numbers of ePWM, eCAP, and eQEP modules are available on F28x7x
devices. See the device datasheet for more information.
