This is a module for the Dareplane project. It provides a speller interface with individual symbols highlighted using the noise-tagging protocol, known to evoke the code-modulated visual evoked potential (c-VEP) in the EEG.

To download the dp-cvep-speller, use:

git clone https://github.com/thijor/dp-cvep-speller.git

Make sure that requirements are installed, ideally in a separate conda environment:

conda create --name dp-cvep-speller python=3.10
conda activate dp-cvep-speller
pip install -r requirements.txt

To run the dp-cvep-speller module in isolation, use:

python -m cvep_speller.speller.py

This will run a minimal example using defaults as specified in configs/speller.toml.

• While the test_decoder_selection seems to work as intended, tests can fail due to a dynamic refresh rate of the screen (e.g., MacBooks)

• Add a checking function to ensure that the screen refresh rate is as specified in the config
