LAUNCHXL-F28379D Overview

Getting Started With the LAUNCHXL-F28379D

4.1

Getting Started

The first time the LAUNCHXL-F28379D board is powered-on a demo application will automatically start.

Connect the LAUNCHXL-F28379D to a free USB port using the included mini-USB cable. The demo

application will start with LEDs D9 and D10 blinking to show the device is active. If your board does not

start the demo application, try setting switch S1 in the following positions and resetting the board: 1-UP, 2-

UP, 3-DOWN.

4.2

Demo Application, ADC Sampling

The LAUNCHXL-F28379D includes a pre-programmed TMS320F28379D device. When the LaunchPad is

powered via USB, the demo starts with an LED blink sequence. After a few seconds the device switches

into an ADC sample mode.

Every 1 second the ADC samples pin ADCIN14 and the sampled data is represented as follows: If the

sample is above mid-scale (2048), the blue LED D10 will illuminate. If the sample is below mid-scale, the

red LED D9 will illuminate.

In addition to the LED indicators, ADC sample information is also displayed on your PC through the

USB/UART connection. To view the UART information on your PC, first determine the COM port

associated with the LaunchPad. To do this in Windows, right click on My Computer and click on

Properties. In the dialog box that appears, click on the Hardware tab and open Device Manager. Look for

an entry under Ports (COM & LPT) titled "USB Serial Port (COMX)", where X is a number. Remember this

number for when you open a serial terminal. The demo applications UART data was written and debugged

using PuTTY, and for the best user experience we recommend you use PuTTY to view the UART data.

PuTTY can be downloaded from the following URL:

http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html

Open your serial terminal program and open the COM port you found previously in device manager with

the following settings: 115200 Baud, 8 data bits, no parity, 1 stop bit. After opening the serial port in your

serial terminal, reset the LaunchPad with the reset push button S3 and observe the serial terminal to see

the TI logo in ASCII art.

4.3

Program and Debug the ADC Sample Demo Application

The project and associated source code for the C2000 Delfino LaunchPad demo is included in the

C2000Ware software package and should automatically be found by the TI Resource Explorer in Code

Composer Studio. In the resource explorer, navigate C2000Ware to find the

device_support\f2837xd\examples folder. Expand this item and LAUNCHXL-F28379D, then select the

LaunchPad Demo Application. Follow the steps in the main pane of the resource explorer to import, build,

debug, and run this application.

4.4

Using Other C2000Ware Examples

Including the LaunchPad demo example described above, C2000Ware provides many examples

demonstrating a majority of the features of the F2837x MCU. Most examples are configured by default to

use the TMDSCNDC28379D ControlCARD, which has a different on-board clocking circuit. As such, some

examples may not work as intended without minor modification. To make this easier on the designer,

compiler switch has been added to automatically pick the proper clock configuration based on adding

"_LAUNCHXL_F28379D" as a predefined symbol in the project properties. Refer to Section 8for more

information on how and where to define this symbol.

Hardware Configuration

The F28379D LaunchPad provides users with several options for configuring the board.
