Texas Instruments C2000™ DIMM100 Experimenter's Kit Overview

Introduction

The C2000™ DIMM100 Experimenter's Kit offers a quick, easy, and low-cost method to evaluate the TMS320F28x family of devices. The kit comprises a docking station and an F28x controlCARD™. The docking station serves as a small baseboard compatible with any DIMM100 plug-in controlCARDs, providing user access to all key GPIO and ADC signals of the F28x device. It also features two prototyping areas with 0.1" spaced plated through holes for wire-wrapping and soldering.

Docking Station Features:

• Onboard XDS100v1 USB emulator or support for external JTAG emulators.
• Power options: 5-V supply from USB or an external power supply.
• UART communications via onboard USB-to-UART bridge (requires J9 jumper).
• Dedicated 5.0-V and 3.3-V supplies for prototyping areas.
• All key signals are accessible via clearly labeled header pins.

DIM100 controlCARD Features:

• Small form factor: 90 mm × 25 mm (3.5" x 1").
• Dual In Line Memory Module (DIMM) style, vertical, plug-in boards.
• Include necessary support circuitry for reliable C2000 MCU operation (clock, supply LDO, decoupling, pull-ups).
• Robust design suitable for noisy electrical environments.
• Key GPIO, ADC, and other important signals routed to gold edge connector fingers.
• Extensive supply pin decoupling with L+C close to pins.
• Clamping diode protection at ADC input pins.
• Anti-aliasing filter (noise filter) at ADC input pins.
• Ground plane.

The kit includes a Hardware Developer's Package containing files for easy copying or redeploying the technology. This package includes:

• Schematics (source or .PDF files).
• Bill of Materials (BOM).
• Gerber files for modification.
• Pin-out table detailing key signals on the 100-pin connector.
• DIMM100 pin/socket mechanical details.
• PCB files created with ExpressPCB software (for the docking station).

Note on Components: The EVM contains a crystal component (CSTCR6M00G53Z-R0) with > 0.1% Lead Titanium Zirconium Oxide, listed in EU REACH as a Substance of Very High Concern. This component and a ceramic resistor component (CRCW08050000Z0EA) are RoHS exempt through exemption 7(c)-1.

Hardware Setup

This section guides you through setting up the board to utilize the onboard USB emulation and the 5-V USB power supply.

1. Unpack the DIMM style controlCARD.
2. Spread open the winged retaining clips on connector J1.
3. Gently place the DIMM card into the connector slot, aligning the two keyed notches. Position the card's bottom corners inside the retaining clips.
4. Apply even vertical pressure from both ends of the card until the clips snap and lock securely.

Note: To remove or eject the card, spread the retaining clips open with your thumbs.

5. Set switch 1 (SW1) to the ON position and connect the USB cable to USB connector JP2.
6. To power the board for software development or running projects, set SW1 to the USB position. This enables the board to use the 5-V USB supply.
7. For comprehensive details including schematics and pin-out tables, refer to the Hardware Developer's package, DockingStnHWdevPkg.

Software Setup

All necessary documentation, software, and hardware files for using the experimenter's kit and developing for C2000 MCUs are available in the controlSUITE package. This package includes the Hardware Developer's package for the baseboard and all C2000 controlCARDs, as well as software and documentation for other kits.

To install controlSUITE:

1. Visit http://www.ti.com/controlsuite and download the installer.
2. Run the installer and select the experimenter's kit during the installation process.
3. By default, controlSUITE is installed in the C:\TI\controlSUITE directory.

Key locations within controlSUITE:

• Example software: \controlSUITE\development_kits\TemplateProjects\
• Hardware documentation: \controlSUITE\development_kits\~ExperimentersKits
• controlCARD hardware developer's package: \controlSUITE\development_kits\~controlCARDs
• Additional device examples: \controlSUITE\device_support

Using the Onboard USB JTAG Emulation

The onboard USB JTAG emulation utilizes XDS100v1 technology from Texas Instruments, providing a straightforward connection for Code Composer Studio™ development.

To set up onboard USB JTAG emulation:

1. Download and install Code Composer Studio (CCS).
2. Connect the USB docking station to an available USB port.
3. When prompted for drivers, select the option to search your local computer for drivers rather than searching online.
4. Once Windows completes the driver installation, the onboard USB JTAG emulator is ready for use.
5. In CCS, create a new target configuration: Navigate to Target > New Target Configuration...
6. Name your configuration, for example, xds100v1-f28X (replace X with your C2000 MCU part number, e.g., F28035). Use the shared location.
7. Select the device corresponding to your kit. The onboard emulator is identified as the Texas Instruments XDS100v1 USB Emulator.
8. Choose the connection type as Texas Instruments xds100v1 USB Debug Probe (or Emulator). In the Board or Device field, select the C2000 device present on your controlCARD.
9. Import your project by selecting Project > Import Existing CCS/CCE Eclipse Project. Browse to locate the applicable project.

For troubleshooting on Windows, check the Device Manager. With the docking station connected, you should see TI XDS100 Channel A and TI XDS100 Channel B. If they are not visible, consult the E2E thread for assistance.

Running Your First Program

The "Flashing Leds" project, provided as a template within the controlSUITE download, enables users to quickly begin working with a C2000 MCU. Documentation for this project is located at:

\controlSUITE\development_kits\TemplateProjects\~Docs\SystemFrameworkOverview.pdf

This project can be imported into CCS. When importing, ensure the option to import the project into your workspace is unchecked.

Other Types of controlCARDs™

This document focuses on a subset of controlCARDs in the DIM100 format, such as the TMDSDOCK28335 and TMDSDOCK28035. These controlCARDs lack onboard emulation circuitry and rely on the baseboard for emulation. Other controlCARDs, like the TMDSCNCD28069MISO, feature an isolated debug probe, requiring the use of the on-card emulator for CCS connection.

For newer devices, such as the F28379D, a different connector standard, HSEC180, is used. The TMDSADAP180TO100 adapter can facilitate the use of newer controlCARDs with DIM100 baseboards. However, there is currently no provision for connecting a DIM100 controlCARD to a baseboard designed for an HSEC180 connector.
