Peripheral Explorer Kit Overview
The Peripheral Explorer Kit is an evaluation board designed to allow experimentation with many of theperipherals available in the C2000™ F28x family of microprocessors. The board is designed to accept anyof controlCARD and contains all hardware (controlCARD socket, power supply) required for normal usage.The kit is self-contained and contains multiple experiments in which external equipment, such asoscilloscopes, are not required. In the majority of these examples, one peripheral reads the output of adifferent peripheral, confirming the operation of both.

Component Description
+5V Power In DC power supply from plug pack (5-V supply may be used as well)Main Pwr SW1 - Master power switch for entire EVMEmulator Power Jumper Sets the voltage sent to power the emulator. No jumper means no power will be sent to an emulator, ajumper at “5V” will power the emulator with 5 V, and a jumper at “3V3” will power the emulator with 3.3V.JTAG Connector for external JTAG emulatorCAN External pins available for connection to two parallel CAN devicesEEPROM 256K SPI-based EEPROMHex Encoder 4-bit hex encoder which sets the values of GPIOs 12-15SCI Boot Pins Controls how the controlCARD bootsIf no jumpers are placed the target boots from flashIf a jumper is placed at “34”, a F2808 controlCARD boots from SCIIf a jumper is placed at “84”, a F28335 controlCARD boots from SCIPotentiometers Divide a 3.3-V input into a voltage value to be read by ADC-A0 and ADC-A1LEDs LED1 and LED2 controlled by GPIO-09 and GPIO-11Comms Serial communications UART (connects to the Quick Start GUI)IR Receiver Uses the eCAP module to read signals sent by a IR transmitter. The software included with this kit isconfigured to work with the Sharp TV protocol, for the included Philips universal remote this is code0509.Headphone-Out Output from the TI AIC23B codec that is controlled by the F28x MCU (headphones not included in thispackage)Audio-In Input to the TI AIC23B codec (line-in audio cable not included in this package)ADC pins Spare ADC pins available to be connected as desiredDAC output Output of a filtered ePWM. The ePWM output is connected to a second-order passive filter thenconnected to these pinsEPWM to ECAP Connecting a jumper across these headers allows for an experiment to be done where the eCAPloopback enable module reads the duty cycle and period of the ePWM output

2 Hardware Set Up
2.1 Test drive with GUI – (skip if you need only emulation support)
2.2 Code Composer Studio Software Development Platform Emulation - Additional Steps
www.ti.com Hardware Set Up
All the hardware needed to get started (except the emulator) is included in this package (suggestedemulators are listed near the end of this document). The application specific motherboard provided in thiskit can be used in one of two ways:1. Test Drive – Using the provided GUI application, the user does not require Code Composer Studio™or emulation tools. This provides a great way to run or demo the application code quickly and see whatfunctionality the hardware offers. Note: The same functionality can be achieved by using the CodeComposer Studio Watch Window and slider features during emulation in the second mode.2. Code Composer Studio Software Development Platform – With the project code provided, theapplication can be modified, compiled, loaded, and run in a development environment. CodeComposer Studio and Emulation HW tools are required for this.
Follow these steps to set up the hardware for either the GUI or Software Development PlatformStep 1. Unpack the DIMM style controlCARD.Step 2. Spread open the winged retaining clips on connector J2.Step 3. Sit the DIMM card loosely in the connector slot. Make sure to align the 2 keyed notches andposition the card bottom corners inside the retaining clips (see picture below).Step 4. Push vertically down using even pressure from both ends of the card until the clips snap andlock. (note: to remove or eject the card spread open the retaining clips with thumbs).Step 5. Ensure switch 1 (SW1) is in the off position and connect the included power supply to thepower jack .
Step 1. Plug in the serial cable provided to connector J4 making sure the red wire aligns with the “Rx”pin on EVM.Step 2. Inserted a jumper in position 84 on boot pins.Step 3. Plug the DB9 connector into your PC using either a serial port or a serial-to-USB converterdongle.Step 4. Turn on the power once you are done with the TI Software download, see Software SetupGUI-TestDrive.
Step 1. Depending on your emulator type, place the jumper at J2 to either the 3.3V or 5V positionStep 2. Connect the JTAG emulator cable to connector J1Step 3. Turn on power once you are done with the TI Software download, see Software Setup CodeComposer Studio-Development.
Note: For full details (schematics, pin-out table) of the hardware see the Hardware Developer'sPackage, PeripheralExplorer-HWdevPkg. See Software Setup for download location.

3 Software Set Up
Software Set Up www.ti.com
The Peripheral Explorer Kit application software example, GUI, step-by-step lab style documentation, andother useful soft collateral can all be found on the TI website. If you already have your own softwareproject and do not require this collateral, skip this section. As explained in the HW setup section, thetarget mother board can be run either with the GUI or Code Composer Studio. The GUI executable file isfound as part of the main software download. Follow the steps below for either case.
To run any of the application specific software in Code Composer Studio, you must first install the baselinecode which contains the header files, libraries, etc. If you already have the base-line software installed,skip the baseline install steps and go to the Peripheral Explorer Kit section.
