This little tool allows you to stream any csv file containing a list of numbers across a network port. It has adjustable parameters that you can adjust too.
The Signal Streamer CLI provides a convenient way of generating a real time signal. Anyone who works on analysing realtime signals can use the provided example code to connect their project to a continuous stream of incoming signal, without requiring physical hardware.
- Normalizing: normalizes signal to -1 -> 1 or 0 -> 1000 when in integer only mode
- Port: the CLI transmits to any local port and defaults to 127.0.0.1:12345
- Sample rate: replay the provided data at any sample rate up to 1000 Hz
- Skip samples: only transmit every nth sample
- Filter: adjustable cutoff high pass and low pass filters
- Noise: add noise up to 100% of level of signal
Signal Streamer CLI:
cargo build --bin Signal-Streamer-CLI
Receiver Demo:
cargo build --bin receive-demo

Options:
-f, --filename <FILENAME> CSV File (single column only)
-p, --port <PORT> Network Port (127.0.0.1:xxxxx) [default: 12345]
--sample-f <SAMPLE_F> Sample freq of data provided [default: 200]
--skip-n <SKIP_N> Skip n samples every transmission [default: 0]
--lp-filter <LP_FILTER> LP Filter (default: same as sample_f) [default: 200]
--hp-filter <HP_FILTER> HP Filter [default: 0]
--normalize Normalize (from -1 to 1, or 0 to 1000 in int mode)
--noise <NOISE> Noise Level Percent (0 -> 100) [default: 0]
--int-mode Default is floats from -1 -> +1 (int mode: ints from 0 -> 1000)

Run the following commands in two separate terminals: (two demo scripts are provided for receiving, one in rust, the other in python)
cargo run --bin Signal-Streamer-CLI -- -f ./Test-Signal.csv --int-mode
cargo run --bin receive-demo // rust option
python3 ./Python_Receive.py // python option
