2 Kit ContentsThe LAUNCHXL-F28377S LaunchPad experimenter kit includes the following items:• C2000 Delfino LaunchPad Board (LAUNCHXL-F28377S)• Mini USB-B Cable, 0.5m• Quick Start Guide

2.1 Revisions

The first production revision of the LAUNCHXL-F28377S in 2016 was Revision 1.0.

All Revisions:• Resistor R7 in the oscillator circuit is incorrectly placed or should not be installed. This resistor may

impact startup time or robustness of the clocking circuit over the full operating range of the MCU ordifferent physical layouts of this circuit. The probability is low that this resistor will have any impact onthe functionality of this EVM as is not intended to be operated outside of Standard Temperature andPressure in a lab or prototype environment. Do not use this circuit as reference. Follow therequirements for the Oscillator schematic as documented in the MCU Datasheet.

3 InstallationThe F28377S LaunchPad is supported in Code Composer Studio.

3.1 Code Composer Studio

3.1.1 Download the Required SoftwareCode Composer Studio IDE is available for free without any restriction when used with the XDS100 debugprobe on the C2000 LaunchPad. The software can be downloaded from the C2000 LaunchPad page atti.com/launchpad. At this site, you can also download a copy of controlSUITE that includes drivers,examples, and other support software needed to get started.

3.1.2 Install the SoftwareOnce downloaded, install Code Composer Studio and the controlSUITE package.

3.1.3 Install the HardwareAfter Code Composer Studio is installed, plug the supplied USB cable into the C2000 LaunchPad boardand into an available USB port on your computer.

Windows® will automatically detect the hardware and ask you to install software drivers. Let Windows runa search for the drivers and automatically install them. After Windows successfully installs the drivers forthe integrated XDS100v2 debug probe, your LaunchPad is now ready for use.

4 Getting Started with the LAUNCHXL-F28377S

4.1 Getting StartedThe first time the LAUNCHXL-F28377S is used, a demo application automatically starts when the board ispowered from a USB host. If your board does not start the demo application, try placing S1 in the followingpositions and resetting the board: UP - UP - DOWN. To start the demo, connect the LAUNCHXL-F28377Swith the included mini-USB cable to a free USB port. The demo application starts with the LEDs flashingto show the device is active.

Getting Started with the LAUNCHXL-F28377S www.ti.com




4.2 Demo Application, ADC SamplingThe LAUNCHXL-F28377S includes a pre-programmed TMS320F28377S device. When the LaunchPad isconnected via USB, the demo starts with an LED flash sequence. After a few seconds the device switchesinto an ADC sample mode.

Each second the ADC is sampled and the sample data is relayed to you. If the sample is above mid-scale(2048), the red LED will light. However, if the sample is below mid-scale the blue LED will light.

In addition to the LED display, sample information is also displayed on your PC through the USB/UARTconnection. To view the UART information on your PC, first figure out the COM port associated with theLaunchPad. To do this in Windows, right click on My Computer and click on Properties. In the dialog boxthat 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 aserial terminal. The demo applications UART data was written and debugged using PuTTY, and for thebest user experience we recommend you use PuTTY to view the UART data. PuTTY can be downloadedfrom 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 withthe following settings: 115200 Baud, 8 data bits, no parity, 1 stop bit. After opening the serial port in yourserial terminal, reset the Launchpad with the reset push button and observe the serial terminal for asurprise.

4.3 Program and Debug the ADC Sample Demo ApplicationThe project and associated source code for the C2000 Delfino LaunchPad demo is included in thecontrolSUITE software package and should automatically be found by the TI Resource Explorer in CodeComposer Studio v6. In the resource explorer, open the controlSUITE folder and then the DevelopmentTools entry and look for the C2000 LaunchPad line item. Expand this item and LAUNCHXL-F28377S,then select the LaunchPad Demo Application. Follow the steps in the main pane of the resource explorerto import, build, debug, and run this application.

4.4 Using other ExamplesIncluding the LaunchPad demo example described above, controlSUITE provides many examplesdemonstrating a majority of the features of the F2837x MCU. Most examples are configured by default touse the other hardware which has a different on-board clocking circuit. As such, some examples may notwork as intended without minor modification. To make this easier on the designer, compiler switch hasbeen added to automatically pick the proper clock configuration based on adding "_LAUNCHXL_F28377S"as a predefined symbol in the project properties. Refer to for more information on how and where to definethis symbol.

www.ti.com Hardware Configuration




5 Hardware ConfigurationThe F28377S LaunchPad provides users with several options on how to configure the board.

5.1 ADC ResolutionWhile the F28377S device has a 16 bit ADC, this development kit has been designed to use the ADC inits 12-bit mode. The user can use the ADC in its 16-bit mode by driving the proper differential signals intothe ADC. Performance will not be on par with the data sheet [1] due to the reference circuitry beingdesigned to match the ADC's 12-bit mode.

5.2 Power DomainThe F28377S LaunchPad has several different power domains to enable JTAG isolation. Jumpers JP1,JP2, JP4, and JP5 configure where power is passed.

Jumper Power DomainJP1 Enable 3.3 V from USB (disables isolation)JP2 Enable GND from USB (disables isolation)JP4 Connects target MCU 3.3 V to second set of BoosterPack

headersJP5 Connects target MCU 5 V to second set of BoosterPack headers

5.3 Boot Mode SelectionThe LaunchPad's F28377S device includes a boot ROM that performs some basic start-up checks andallows for the device to boot in many different ways. Most users will either want to perform an emulationboot or a boot to flash (if they are running the application standalone). S1 has been provided to allowusers to easily configure the pins that the bootROM checks to make this decision. The switches on S1correspond to:

Switch Function1 GPIO842 GPIO723 TRSTn

Keep in mind that the debugger does not connect if the device is not in the emulation boot mode (TRSTswitch in the up position). More information about boot mode selection can be found in the Boot ROMsection of the TMS320F2837xS Delfino Microcontrollers Technical Reference Manual (SPRUHX5).

5.4 Connecting a BoosterPackThe F28377S LaunchPad is the perfect experimenter board to start hardware development with theF2837xS devices. All of the connectors are aligned in a 0.1-in (2.54-mm) grid to allow easy andinexpensive development of add on boards called BoosterPacks. These satellite boards can access all ofthe GPIO and analog signals. The the pin out of the connectors can be found in Section 5.

5.5 Device Migration PathApplications developed on the LAUNCHXL-F28377S can easily be migrated to any of these lower costdevices in the F2837xS family:

Frequently Asked Questions (FAQ) www.ti.com




8 Frequently Asked Questions (FAQ)1. Can other programming and debug tools (such as an XDS510 debug probe) be used with the C2000

LaunchPad?2. What versions of Code Composer Studio can be used to develop software for the C2000 LaunchPad?

• While a user could potentially connect an external debug probe to the F28377S device present onthe LaunchPad, it would require some rework of the board. It is recommended that users who wantto use an external debug probe purchase a controlCard and docking station that includes anexternal JTAG connector.

• It is highly recommend that novice users develop applications with Code Composer Studio v6. Thedrivers, examples, and other associated software are tailored to make the user experience assmooth as possible in Code Composer Studio v6.

3. Why can’t I connect to the LaunchPad in Code Composer Studio?• There are a number of things that could cause this and they all have an easy fix.

– Is S1 switch 3 in the down position?This is the TRST pin that enables and disables JTAG functionality on the chip. This switch mustbe in the up position for the debug probe to be able to connect.

– Are both power LEDs lit?The board has two power domains because of the isolated JTAG interface. For low-voltageapplication development, JTAG isolation is not needed and the power domains can becombined to allow for convenience (that is, the board can be powered completely through theUSB). Ensure that jumpers are placed on the posts of JP1 and JP2.

– Are drivers correctly installed for the XDS100v2 present on the LaunchPad?Right click on My Computer and select properties. Navigate to the Hardware tab in the dialogbox and open the device manager. Scroll to the bottom of the list and expand the USB SerialBus controllers item. Are there two entries for TI XDS100 Channel A/B? If not, try unpluggingand replugging in the board. Does Windows give you any messages in the system tray? InDevice Manger, do either of the entries have a yellow exclamation mark over their icon? If so,try reinstalling the drivers.

4. Why is the serial connection not working?• Are you using the correct COM port?

Right click on My Computer and select properties. Navigate to the Hardware tab in the dialog boxand open the device manager. Scroll to Ports (COM & LPT) and expand this entry. Is there a USBSerial Port listed? If so, read the COM number to the right of the entry; this is the COM number youshould be using.

• Are you using the correct baud rate?Most, if not all, of the examples are configured for a baud rate of 115200 when the CPU is runningat 200 MHz. If you have changed the PLL settings or written your own application you may have torecalculate the baud rate for your specific application. For information on how to do this, see theTMS320F2837xS Delfino Microcontrollers Technical Reference Guide (SPRUHX5).

5. Why is my program operating at half the frequency of what I expected?• By default many of the controlSUITE examples are configured to operate on hardware which has a

different clocking circuit, where the external clock is 20 MHz instead of 10 MHz as found on thisEVM.

• A compiler switch was added to various functions to allow a user to change the clockingconfiguration based on the status of a predefined symbol.

• To ensure the PLL is correctly configured for the LAUNCHXL-F28379D, Add"_LAUNCHXL_F28377S" to the predefined symbols list.

• Access the Predefined symbols list by accessing the Project Properties, Navigating to Build »C2000 Compiler » Advanced Options » Predefined Symbols.
