www.ti.com 2 Kit Contents The LAUNCHXL-F28377S LaunchPad experimenter kit includes the following items: • C2000 Delfino LaunchPad Board (LAUNCHXL-F28377S) • Mini USB-B Cable, 0.5m • Quick Start Guide Kit Contents 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 or different physical layouts of this circuit. The probability is low that this resistor will have any impact on the functionality of this EVM as is not intended to be operated outside of Standard Temperature and Pressure in a lab or prototype environment. Do not use this circuit as reference. Follow the requirements for the Oscillator schematic as documented in the MCU Datasheet. 3 Installation The F28377S LaunchPad is supported in Code Composer Studio. 3.1 Code Composer Studio 3.1.1 Download the Required Software Code Composer Studio IDE is available for free without any restriction when used with the XDS100 debug probe on the C2000 LaunchPad. The software can be downloaded from the C2000 LaunchPad page at ti.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 Software Once downloaded, install Code Composer Studio and the controlSUITE package. 3.1.3 Install the Hardware After Code Composer Studio is installed, plug the supplied USB cable into the C2000 LaunchPad board and into an available USB port on your computer. Windows® will automatically detect the hardware and ask you to install software drivers. Let Windows run a search for the drivers and automatically install them. After Windows successfully installs the drivers for the integrated XDS100v2 debug probe, your LaunchPad is now ready for use. 4 Getting Started with the LAUNCHXL-F28377S 4.1 Getting Started The first time the LAUNCHXL-F28377S is used, a demo application automatically starts when the board is powered from a USB host. If your board does not start the demo application, try placing S1 in the following positions and resetting the board: UP - UP - DOWN. To start the demo, connect the LAUNCHXL-F28377S with the included mini-USB cable to a free USB port. The demo application starts with the LEDs flashing to show the device is active.

Getting Started with the LAUNCHXL-F28377S 4.2 Demo Application, ADC Sampling www.ti.com The LAUNCHXL-F28377S includes a pre-programmed TMS320F28377S device. When the LaunchPad is connected via USB, the demo starts with an LED flash sequence. After a few seconds the device switches into 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/UART connection. To view the UART information on your PC, first figure out 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 and observe the serial terminal for a surprise. 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 controlSUITE software package and should automatically be found by the TI Resource Explorer in Code Composer Studio v6. In the resource explorer, open the controlSUITE folder and then the Development Tools 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 explorer to import, build, debug, and run this application. 4.4 Using other Examples Including the LaunchPad demo example described above, controlSUITE provides many examples demonstrating a majority of the features of the F2837x MCU. Most examples are configured by default to use the other hardware 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_F28377S" as a predefined symbol in the project properties. Refer to for more information on how and where to define this symbol. 4 LAUNCHXL-F28377S overview Copyright © 2015–2019, Texas Instruments Incorporated SPRUI25D–June 2015–Revised March 2019 Submit Documentation Feedback

www.ti.com 5 Hardware Configuration The F28377S LaunchPad provides users with several options on how to configure the board. Hardware Configuration 5.1 ADC Resolution While the F28377S device has a 16 bit ADC, this development kit has been designed to use the ADC in its 12-bit mode. The user can use the ADC in its 16-bit mode by driving the proper differential signals into the ADC. Performance will not be on par with the data sheet [1] due to the reference circuitry being designed to match the ADC's 12-bit mode. 5.2 Power Domain The F28377S LaunchPad has several different power domains to enable JTAG isolation. Jumpers JP1, JP2, JP4, and JP5 configure where power is passed. Jumper JP1 JP2 JP4 JP5 Power Domain Enable 3.3 V from USB (disables isolation) Enable GND from USB (disables isolation) Connects target MCU 3.3 V to second set of BoosterPack headers Connects target MCU 5 V to second set of BoosterPack headers 5.3 Boot Mode Selection The LaunchPad's F28377S device includes a boot ROM that performs some basic start-up checks and allows for the device to boot in many different ways. Most users will either want to perform an emulation boot or a boot to flash (if they are running the application standalone). S1 has been provided to allow users to easily configure the pins that the bootROM checks to make this decision. The switches on S1 correspond to: Switch 1 2 3 Function GPIO84 GPIO72 TRSTn Keep in mind that the debugger does not connect if the device is not in the emulation boot mode (TRST switch in the up position). More information about boot mode selection can be found in the Boot ROM section of the TMS320F2837xS Delfino Microcontrollers Technical Reference Manual (SPRUHX5). 5.4 Connecting a BoosterPack The F28377S LaunchPad is the perfect experimenter board to start hardware development with the F2837xS devices. All of the connectors are aligned in a 0.1-in (2.54-mm) grid to allow easy and inexpensive development of add on boards called BoosterPacks. These satellite boards can access all of the GPIO and analog signals. The the pin out of the connectors can be found in Section 5. 5.5 Device Migration Path Applications developed on the LAUNCHXL-F28377S can easily be migrated to any of these lower cost devices in the F2837xS family: Part Number TMS320F28377S TMS320F28376S TMS320F28375S TMS320F28374S Description 32 Bit Real Time Microcontroller, 200 Mhz, 1024KB Flash, 164KB RAM, 16 Bit ADC 32 Bit Real Time Microcontroller, 200 Mhz, 512KB Flash, 132KB RAM, 16 Bit ADC 32 Bit Real Time Microcontroller, 200 Mhz, 1024KB Flash, 164KB RAM, 12 Bit ADC 32 Bit Real Time Microcontroller, 200 Mhz, 512KB Flash, 132KB RAM, 12 Bit ADC SPRUI25D–June 2015–Revised March 2019 Submit Documentation Feedback Copyright © 2015–2019, Texas Instruments Incorporated LAUNCHXL-F28377S overview 5
