3.3 Driver Installation

Before connecting the board to your computer, ensure you have the necessary drivers installed. Typically, the EZ-USB FX2LP chip requires specific drivers for your operating system (Windows, Linux). These drivers are usually available from the chip manufacturer's website (Cypress/Infineon) or from the vendor of the development board. Follow the instructions provided with the driver package for installation.

For Windows users, the device might appear as an unknown device in Device Manager until the correct drivers are installed. Refer to the driver documentation for specific installation steps.

3.4 Connecting the Board

1. Connect one end of a mini-USB cable to the mini-USB port on the development board.
2. Connect the other end of the USB cable to an available USB 2.0 port on your computer.
3. Once connected, your operating system should detect the device. If drivers are correctly installed, it will be recognized.

4. Operating Instructions

4.1 Firmware Programming

The on-board 16KB EEPROM (24LC128) allows for in-system programming of the USB firmware. This is crucial for configuring the device's Vendor ID (VID) and Product ID (PID), and for loading custom firmware to enable specific functionalities, such as logic analyzer mode.

• To program the EEPROM, you will typically use a dedicated programming utility provided by Cypress/Infineon or a compatible open-source tool.
• Ensure the board is connected to your computer and recognized by the programming software.
• Follow the software's instructions to load your desired firmware (.hex or .iic file) onto the EEPROM.

4.2 Using as a Logic Analyzer

With the correct firmware loaded, this board can function as a powerful logic analyzer. You will need compatible software on your computer to capture and analyze digital signals. Popular open-source software like Sigrok (PulseView) is often used with FX2LP-based logic analyzers.

1. Install Logic Analyzer Software: Download and install a compatible logic analyzer software (e.g., Sigrok PulseView) on your computer.
2. Connect to Target Circuit: Use jumper wires or test clips to connect the GPIO pins of the development board to the test points on your target circuit. Ensure proper grounding (GND) connections.
3. Configure Software: Launch the logic analyzer software. Select the Comimark board (or the generic FX2LP device) as your hardware. Configure the sampling rate (up to 48MHz) and the channels you wish to monitor.
4. Capture Data: Start the capture process in the software. Trigger conditions can be set to capture data when specific signal changes occur.
5. Analyze Signals: Once data is captured, use the software's analysis tools to decode protocols (I2C, SPI, UART, etc.), measure timings, and debug your digital circuits.

5. Maintenance

• Storage: Store the board in a dry, anti-static environment away from direct sunlight and extreme temperatures.
• Cleaning: Use a soft, dry cloth to clean the board. Avoid using liquids or abrasive cleaners.
• Handling: Handle the board by its edges to avoid touching components, especially the pins, which can be sensitive to electrostatic discharge (ESD).
• Firmware Updates: Periodically check for updated drivers or firmware from the manufacturer or community resources to ensure optimal performance and compatibility.

6. Troubleshooting

• Device Not Recognized:
  • Ensure USB cable is securely connected.
  • Verify that the correct drivers for the CY7C68013A-56 chip are installed for your operating system.
  • Try a different USB port or cable.
• No Signal Capture:
  • Check all connections between the board and the target circuit, especially ground (GND).
  • Confirm that the logic analyzer software is correctly configured for the device and channels.
  • Ensure the target circuit is powered on and generating signals.
  • Verify that the firmware on the EEPROM is correctly loaded and enables logic analyzer functionality.
• Incorrect Readings:
  • Adjust the sampling rate in your software to match the speed of the signals being analyzed.
  • Check for noise or interference in your test setup.
  • Ensure proper voltage levels are being supplied to the board and the target circuit.
