A simple code to log data from Serial Port
This script logs data coming from a Serial Port (like COM1 or /dev/ttyUSB0) in a CSV file.
Seriuslogger expects arrays of bytes, where every recognized '\n' is considered a new line in the CSV file, categorizing a Row. A row can also have an array of content. This inner array will be the CSV columns, and they are recognized by a separator coming from the serial data, as default ';'.
For the sake of example, the following data coming from the serial port:
"time;q_1;q_2\n1001;10.2;0.0\n1002;10.7;0.3\n"
Or in a more expressive form:
"time;q_1;q_2\n"
"1001;10.2;0.0\n"
"1002;10.7;0.3\n"
Will be interpreted by Seriuslogger and saved in the CSV as:
| time | q_1 | q_2 |
|---|---|---|
| 1001 | 10.2 | 0.0 |
| 1002 | 10.7 | 0.3 |
(Optional) Create a virtualenv, by your preference, and jump to it.
Install all dependencies using the following command
pip install -r requirements.txt
Python version 3.7.7
Simple run
py serius_logger.py [-h] [-p PORT_DEVICE] [-b BAUDRATE] [-n NAME] [-s SEP]
For help on-the-go, simple use
py seriuslogger.py -h
- -h, --help show this help message and exit
- -p PORT_DEVICE, --port_device PORT_DEVICE Port where device is connected (default: COM1)
- -b BAUDRATE, --baudrate BAUDRATE Device baudrate in bps (default: 9600)
- -n NAME, --name NAME Files Output name (default is dynamic) (default: YYmmddHHMMSS.csv)
- -s SEP, --sep SEP String separator coming from serial (default: ;)
When trying to log a specified serial port, an exception may be thrown if no port is available within the specified name. Example:
SerialException("could not open port {!r}: {!r}".format(self.portstr, ctypes.WinError())) serial.serialutil.SerialException: could not open port 'COM1': FileNotFoundError(2, 'The system cannot find the file specified.', None, 2)
Just certify the port availability and spelling. Once done, try again.
