TMS320F2837xD Microcontroller Workshop - Communications 12 - 1
Communications
Introduction
The TMS320C28x contains features that allow several methods of communication and data
exchange between the C28x and other devices. Many of the most commonly used
communications techniques are presented in this module.
The intent of this module is not to give exhaustive design details of the communication
peripherals, but rather to provide an overview of the features and capabilities. Once these
features and capabilities are understood, additional information can be obtained from various
resources such as documentation, as needed. This module will cover the basic operation of the
communication peripherals, as well as some basic terms and how they work.
Module Objectives
Module Objectives
Serial Peripheral Interface (SPI)
Serial Communication Interface (SCI)
Multichannel Buffered Serial Port (McBSP)
Inter-Integrated Circuit (I2C)
Universal Serial Bus (USB)
Controller Area Network (CAN)
Note: Up to 3 SPI modules, 4 SCI modules, 2 McBSP modules, 2 I2C modules,
1 USB module, and 2 CAN modules are available on the F28x7x devices
The F2837xD dual-core MCU includes numerous communications peripherals that extend the
connectivity of the device. There are up to three Serial Peripheral Interface (SPI) modules, four
Serial Communication Interface (SCI) modules, two Multi-channel Buffered Serial Port (McBSP)
modules, two Inter-Integrated Circuit (I2C) modules, two Controller Area Network (CAN) modules,
one Universal Serial Bus (USB) module, and one Universal Parallel Port (uPP) module. These
peripherals can be assigned to either the CPU1 subsystem or the CPU2 subsystem, except for
the USB and uPP which is dedicated to only the CPU1 subsystem.
