F28335 、串口通信（SCI）实验

F28335芯片上没有USB接口啊？

TI上的F28335的USB口是用来供电和当成仿真器使用的，不是串口，如果需要串口，在板子上有个4个针的接口，那个口是串口。

需要串口，在板子上有个4个针的接口，那个口是串口

这个4个针的接口用什么线接，接在什么地方呢？

菜鸟一个，麻烦高手了。

原文是下面，dsp套装好像没有串口通信的线，要另外买？

Objective

The objective of this lab is to establish an SCI transmission between the  F28338x and  a serial

port of a PC.

The SCI-A communication channel is used to send data from F28335 to a host, using RS232

voltage levels. The F28335 controlCARD   has an onboard RS232-transceiver and the signals

Tx and Rx are available at header J12 of the Peripheral E xplorer Board. Plug in the serial

cable provided to header J12  making sure the red wire aligns with the Rx pin  on the

Peripheral  Explorer Board.

A standard DB9 cable (1:1) with male and female connectors can be used to connect to the

host, for example to a COMx  –  interface of a PC. On the host side you need a terminal

program (e.g. Windows XP Hyper Terminal Program or a freeware tool for XP and Vista,

such as “ Hercules”  ( www.HW-group.com). The setup for the communication is as follows:  

•  9600 bit/second

•  8 characters  

•  odd parity

•  1 stop bit  

•  no protocol  

The  task for the F2833x is to  transmit a text message, e.g. “ The  F28335 –  UART is fine! \n\r”

periodically. No interrupt services are used for this  first and  basic test.
