SPRUHH2 – July 2012 Submit Documentation Feedback LAUNCHXL-F28027 C2000 Piccolo LaunchPad Experimenter Kit Copyright © 2012, Texas Instruments Incorporated 5 Getting Started with the LAUNCHXL-F28027 2.2 www.ti.com Install the Software Once downloaded, install Code Composer Studio and the controlSUITE package. 2.3 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 emulator, your LaunchPad is now ready for use. 3 Getting Started with the LAUNCHXL-F28027 3.1 Getting Started The first time the LAUNCHXL-F28027 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-F28027 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. 3.2 Demo Application, Internal Temperature Measurement The LAUNCHXL-F28027 includes a pre-programmed TMS320F28027 device. When the LaunchPad is connected via USB, the demo starts with an LED flash sequence that points toward S3. Press S3 to start the temperature measurement mode. A reference temperature is taken at the beginning of this mode and the LEDs of the LaunchPad are used to display any difference between the current temperature and the reference temperature. Initially, the LED connected to GPIO3 is lit to indicate an 8 in binary, which corresponds to the current temperature being equal to the reference temperature. As the temperature drifts away from the reference, the difference is displayed as a binary increment or decrement of the nibble wide LED display. For instance, if the reference temperature was 30ºC and the current temperature is 33ºC, the LEDs would be (from left to right) ON, OFF, ON, and ON which would be 11 in binary (33-30=3 and 11-8=3). A new reference temperature may be set at any time by pressing S3 again. In addition to the LED display, temperature 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. 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. 3.3 Program and Debug the Temperature Measurement Demo Application The project and associated source code for the C2000 Piccolo LaunchPad demo is included in the controlSUITE software package and should automatically be found by the TI Resource Explorer in Code Composer Studio v5. In the resource explorer, open the controlSUITE folder and then the kits tab and look for the C2000 LaunchPad line item. Expand this item and 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 Hardware Configuration The C2000 LaunchPad gives users several options as to how to configure the board. 6 LAUNCHXL-F28027 C2000 Piccolo LaunchPad Experimenter Kit Copyright © 2012, Texas Instruments Incorporated SPRUHH2 – July 2012 Submit Documentation Feedback Hardware Configuration www.ti.com 4.1 Power Domain The C2000 LaunchPad has two separate power domains for the purpose of allowing JTAG isolation. Jumpers JP1, JP2, and JP3 configure whether the USB power is passed to the target device. 4.2 Jumper Power Domain JP1 3.3 V JP2 Ground JP3 5V Serial Connectivity The LAUNCHXL-F28027 has a USB to UART adapter built in. This makes it easy to print debug information back to the host PC even in isolated environments. However, in some cases the user may wish to connect the Piccolo SCI peripheral (C2000 UART peripheral) to a BoosterPack or other hardware via the header pins. If the SCI pins are connected to both the header pins, the XDS100 UART channel contention would exist and the pins would not be driven to the correct voltage levels. To solve this issue we have included a switch to allow the user to disconnect the Piccolo serial pins from the XDS100 UART connection. When S4 is in the up position, the Piccolo device's SCI is connected to the XDS100 and you are able to receive and send serial information from or to the board. When S4 is in the down position, the Piccolo device's SCI is disconnected from the XDS100 and BoosterPacks, which use serial communication, and can communicate with the Piccolo device. 4.3 Boot Mode Selection The LaunchPad's F28027 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 Function 1 GPIO34 2 GPIO37 3 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 TMS320x2802x Piccolo Boot ROM Reference Guide (SPRUFN6). 4.4 Connecting a Crystal Although the Piccolo device present on the LAUNCHXL-F28027 has an internal oscillator — and for most applications this is sufficient — the LaunchPad offers a footprint for surface mount or through-hole HC-49 crystals for users who require a more precise clock. If you wish to use an external crystal, solder the crystal to the Q1/Q2 footprint and appropriate load capacitors to the C3 and C4 footprints. You also need to configure the device to use the external oscillator in software. 4.5 Connecting a Satellite Board The C2000 LaunchPad is the perfect experimenter board to start hardware development with the F2802x devices. Connectors J1, J2, J5, and J6 and the power supply at J3 are aligned in a 0.1-in (2.54-mm) grid to allow an easy and inexpensive development of a breadboard extension module. These satellite boards can access all of the GPIO and analog signals. The alignment of the connectors and the pin out can be found in Section 5.

Can other programming and debug tools (such as an XDS510 emulator) be used with the C2000 LaunchPad? While a user could potentially connect an external emulator to the F28027 device present on the LaunchPad, it would require some rework of the board. It is recommended that users who want to use an external emulator purchase a controlCard and docking station that includes an external JTAG connector. 2. What versions of Code Composer Studio can be used to develop software for the C2000 LaunchPad? It is highly recommend that novice users develop applications with Code Composer Studio v5. The drivers, examples, and other associated software are tailored to make the user experience as smooth as possible in Code Composer Studio v5. However, there is nothing to prevent a user from creating projects in Code Composer Studio v3 or v4 with the source files available in controlSUITE. Keep in mind that all the projects for the C2000 LaunchPad are Code Composer Studio v5 projects and will not import into Code Composer Studio v3 or v4. Only expert users should attempt to use the LaunchPad with Code Composer Studio v3 or v4. 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 which enables and disables JTAG functionality on the chip. This switch must be in the up position for the emulator to be able to connect. • Are both power LEDs lit? The board has two power domains because of the isolated JTAG interface. For low-voltage application development, JTAG isolation is not needed and the power domains can be combined to allow for convenience (that is, the board can be powered completely through the USB). Ensure that jumpers are placed on the posts of JP1, JP2, and JP3. • 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 dialog box and open the device manager. Scroll to the bottom of the list and expand the USB Serial Bus controllers item. Are there two entries for TI XDS100 Channel A/B? If not, try unplugging and replugging in the board. Does Windows give you any messages in the system tray? In Device 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? There are a few things that could cause this and they are easy to fix. • Is S4 in the up position? S4 connects the F28027 device serial peripheral to the XDS100 serial port, so this switch must be turned on (up) for serial connectivity to function. • Are you using the correct COM port? Right click on My Computer and select properties. Navigate to the Hardware tab in the dialog box and open the device manager. Scroll to Ports (COM & LPT) and expand this entry. Is there a USB Serial Port listed? If so, read the COM number to the right of the entry; this is the COM number you should 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 running at 60 MHz. If you have changed the PLL settings or written your own application you may have to recalculate the baud rate for your specific application. For information on how to do this, see the TMS320x2802x, 2803x Piccolo Serial Communications Interface (SCI) Reference Guide (SPRUGH1). 14 LAUNCHXL-F28027 C2000 Piccolo LaunchPad Experimenter Kit Copyright © 2012, Texas Instruments Incorporated SPRUHH2 – July 2012 Submit Documentation Feedback IMPORTANT NOTICE Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other changes to its semiconductor products and services per JESD46C and to discontinue any product or service per JESD48B.
