4.1. Software Installation (PulseView)

The Mini Logic Analyzer uses PulseView software, which is part of the open-source Sigrok project. Follow these steps to install PulseView:

  1. Download PulseView: Obtain the appropriate installation package for your operating system (Windows, Linux, Mac, Android) from the official Sigrok website or the provided GitHub link: https://github.com/wuxx/nanoDLA/tree/master/software.
  2. انسٽالر هلايو: Double-click the downloaded installation package and follow the on-screen instructions to complete the installation.

4.2. ڊرائيور لڳائڻ

After installing PulseView, you need to install the necessary drivers for the logic analyzer to be recognized by your computer. This process typically involves using the Zadig utility for Windows users.

  1. ڊوائيس ڳنڍيو: Plug the nanoDLA (Mini Logic Analyzer) into a PC USB port using the provided Type-C cable.
  2. شروعاتي سڃاڻپ: Your PC's Device Manager may initially recognize the nanoDLA as an 'other device' or an unknown device.
  3. Launch Zadig: ڳولھيو and open the Zadig utility on your PC. If you don't have it, download it from the Sigrok website or a reliable source.
  4. ڊوائيس چونڊيو: In Zadig, go to 'Options' and toggle on 'List All Devices'. From the dropdown menu, select the device named "fx2lafw" (or similar, look for USB ID 1D50:608C).
  5. انسٽال ڪريو ڊرائيور: Ensure "WinUSB" is selected in the driver field, then click the "Install Driver" button.

After successful driver installation, the nanoDLA should be recognized as a "Universal Serial Bus Device" in your Device Manager.

5. آپريٽنگ هدايتون

Once the software and drivers are installed, you can begin using your Mini Logic Analyzer with PulseView.

  1. Connect and Launch: Plug the nanoDLA into your PC's USB port and open the PulseView سافٽ ويئر.
  2. Configure Channels and Sampزبان جي شرح: In PulseView, configure the desired channels (CH0-CH7) and set the sampling rate. The maximum sampling rate is 24MHz.
  3. شروع ڪريو Sampلنگ: Click the "Run" button (usually located in the top-left corner) to begin sampling ڊيٽا.

  1. Decode Signals: After signals are sampled, you can use the built-in decoders to analyze them. For example, to decode UART sampled data:
    • Click the decoder menu.
    • Select the UART protocol.
    • Configure UART parameters such as channels, baud rate, data bits, and parity type.
    جيampled data will then be decoded and displayed.

Important Note on Sampزبان جي شرح: While the logic analyzer supports up to 24MHz sampling, the actual achievable rate can vary depending on your PC's operating system, USB controller, USB bus status, and USB drivers. For optimal signal reconstruction, a sampling rate at least 5 times (and ideally 10 times) the original signal frequency is recommended. In practice, Linux systems often achieve 24MHz, while most Windows systems (Win7/Win10) typically achieve 16MHz.

6. سار سنڀال

To ensure the longevity and optimal performance of your DKARDU Mini Logic Analyzer, follow these general maintenance guidelines:

  • اسٽوريج: Store the device in a dry, dust-free environment away from extreme temperatures.
  • صفائي: Use a soft, dry cloth to clean the device. Avoid using liquid cleaners or solvents.
  • سنڀالڻ: Handle the device and its accessories with care to prevent physical damage. Avoid bending or stressing the connectors.
  • ڪيبل جي سنڀال: Inspect cables regularly for any signs of wear or damage. Replace damaged cables immediately.

7. مسئلا حل ڪرڻ

If you encounter issues with your Mini Logic Analyzer, consider the following troubleshooting steps:

  • ڊوائيس نه سڃاڻي:
    • Ensure the USB cable is securely connected to both the logic analyzer and your computer.
    • Verify that the drivers are correctly installed using the Zadig utility as described in Section 4.2.
    • ڪوشش ڪريو ڪنھن USBئي USB پورٽ سان پنھنجي ڪمپيوٽر تي.
    • پنهنجي ڪمپيوٽر کي ٻيهر شروع ڪريو.
  • No Signal or Incorrect Readings:
    • Check the connections of the Dupont cables and test clips to your circuit. Ensure they are making good contact.
    • Verify that the correct channels are selected and configured in PulseView.
    • ترتيب ڏيو ايسampling rate. If the signal frequency is too high for the chosen sampling rate, the readings may be inaccurate. Remember the 5x-10x rule mentioned in Section 5.
    • Ensure the logic levels of your circuit are within the input voltage range of the logic analyzer ([-0.5V, 5.25V]).
  • Software Issues (PulseView):
    • Ensure you are using the latest version of PulseView.
    • Consult the PulseView documentation or community forums for specific software-related issues.
