Lovelace is a USB2.0 based dual-channel oscilloscope that utilizes Xilinx® Artix™ 7 FPGA for signal acquisition.
This is a project that I completed within three weeks. Although it may not be high-profile, it can still meet some basic requirements.
For FPGA source code, please refer to https://github.com/Sped0n/ada.
- Acquire speed up to 25MSa/s (single channel)
- Storage depth of up to 25K (dual channel)
- Flexible Trigger Configuration (channel/slope/position/threshold)
- Floating window displays waveform information
- FFT graph support
- Zoom in horizontally on the waveform, with the option to move and adjust a specific region
- Vertical scaling allows waveform to be displayed with proportional magnification
-
Ensure your python version is >=
3.11, not guaranteed to run on lower version.❯ python --version Python 3.11.5
-
Install dependencies.
pip install -r requirements.txt
⚠️ ⚠️ ⚠️ When installing
ftd2xx, please ensure you have FTDI drivers installed or available where the linker looks for shared libraries (e.g., PATH on windows, LD_LIBRARY_PATH or standard library directories on Linux). -
Load binary file into your board.
Please refer to https://github.com/Sped0n/ada/releases.
-
Run the app.
make run # or python -m lovelaceTo connect to the FPGA, click on the
Connectbutton on the bottom. Once the button text changes to Disconnect, you are ready to proceed. Click on RUNfor continuous acquisition or SINGLEfor a single capture.
