Install

1. Download the repository

git clone https://github.com/antmicro/dac-eyescan-test.git

2. Setup virtual environment and install requirements

python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

Usage

1. Connect the DAC38J8x to the host using FTDI
2. Power the DAC38J8x board

python eyescan.py

List available FTDI interfaces

By default, the script picks the first available FTDI interface. --pyftdi-url can be used to select a specific FTDI interface. To list all available interfaces, run the following command in the active virtual environment:

(.venv) $ ftdi_urls.py
Available interfaces:
    ftdi://ftdi:232h:210299BF3425/1  (Digilent USB Device)

You can then pass the preferred url to --pyftdi-url.
