Peripheral Explorer Kit Overview
Quick Start Guide
SPRUGM2 – January 2009
The Peripheral Explorer Kit is an evaluation board designed to allow experimentation with many of the
peripherals available in the C2000™ F28x family of microprocessors. The board is designed to accept any
of 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 as
oscilloscopes, are not required. In the majority of these examples, one peripheral reads the output of a
different peripheral, confirming the operation of both.

Features of the Peripheral Explorer Kit include:
• Multiple peripheral-based examples
– EPWM-based sinusoidal output based on a sine table
– DAC via filtered ePWM signal read by the on-chip ADC
– eCAP-based IR receiver reading
– SPI-based EEPROM interaction
– UART communications header available for host control
– Potentiomers for ADC evaluation
– GPIO-based components such as pushbuttons, hex encoder, and LEDs
– McBSP/DMA-based AIC23 codec software and hardware (F28335 only)
– I2C header for external use
– CAN header for external use
• Quick Start GUI, a friendly way to control / demo the application, based on open
source C# freeware
• Hardware Developer’s Package is available and includes full hardware
documentation such as schematics, bill of materials, and Gerber files.

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 EVM
Emulator Power Jumper Sets the voltage sent to power the emulator. No jumper means no power will be sent to an emulator, a
JTAG Connector for external JTAG emulator
CAN External pins available for connection to two parallel CAN devices
EEPROM 256K SPI-based EEPROM
Hex Encoder 4-bit hex encoder which sets the values of GPIOs 12-15
SCI Boot Pins Controls how the controlCARD boots
Potentiometers Divide a 3.3-V input into a voltage value to be read by ADC-A0 and ADC-A1
LEDs LED1 and LED2 controlled by GPIO-09 and GPIO-11
Comms 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 is
Headphone-Out Output from the TI AIC23B codec that is controlled by the F28x MCU (headphones not included in this
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 desired
DAC output Output of a filtered ePWM. The ePWM output is connected to a second-order passive filter then
EPWM to ECAP Connecting a jumper across these headers allows for an experiment to be done where the eCAP
loopback enable module reads the duty cycle and period of the ePWM output
jumper at “5V” will power the emulator with 5 V, and a jumper at “3V3” will power the emulator with 3.3
V.
If no jumpers are placed the target boots from flash
If a jumper is placed at “34”, a F2808 controlCARD boots from SCI
If a jumper is placed at “84”, a F28335 controlCARD boots from SCI

2 Hardware Set Up
All the hardware needed to get started (except the emulator) is included in this package (suggested
emulators are listed near the end of this document). The application specific motherboard provided in this
kit 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 what
functionality the hardware offers. Note: The same functionality can be achieved by using the Code
Composer Studio Watch Window and slider features during emulation in the second mode.
2. Code Composer Studio Software Development Platform – With the project code provided, the
application can be modified, compiled, loaded, and run in a development environment. Code
Composer Studio and Emulation HW tools are required for this.
Follow these steps to set up the hardware for either the GUI or Software Development Platform
Step 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 and
Step 4. Push vertically down using even pressure from both ends of the card until the clips snap and
Step 5. Ensure switch 1 (SW1) is in the off position and connect the included power supply to the
Hardware Set Up
position the card bottom corners inside the retaining clips (see picture below).
lock. (note: to remove or eject the card spread open the retaining clips with thumbs).
power jack .
2.1 Test drive with GUI – (skip if you need only emulation support)
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 converter
dongle.
Step 4. Turn on the power once you are done with the TI Software download, see Software Setup
GUI-TestDrive.
2.2 Code Composer Studio Software Development Platform Emulation - Additional Steps
Step 1. Depending on your emulator type, place the jumper at J2 to either the 3.3V or 5V position
Step 2. Connect the JTAG emulator cable to connector J1
Step 3. Turn on power once you are done with the TI Software download, see Software Setup Code
Composer Studio-Development.
Note: For full details (schematics, pin-out table) of the hardware see the Hardware Developer's
Package, PeripheralExplorer-HWdevPkg. See Software Setup for download location.
