For an example log file , get it here

Serial Plotter

comchan --port <port> --baud <baud_rate> --plot

# OR 

comchan -p <port> -r <baud_rate> --plot

Automatically detect serial ports

comchan --auto    ##Defaults baud rate to 9600

#OR 

comchan --auto --baud <baud_rate>  # For non-default baud rates like 115200

# OR 

comchan --auto -r <baud_rate>

Use a Configuration file

As of version 0.1.9, you can now create your own configuration file to use ComChan, which means that you won't have to type all the flags.

# Generate default configuration file 

comchan --generate-config   # Generates the default config file at ~/.config/comchan/comchan.toml

Here is an example configuration file

# ComChan Configuration File
#
# This file contains default settings for comchan serial monitor.
# Command line arguments will override these settings.
#
# To use auto-detection, set port = "auto"
# Available parity options: "none", "odd", "even"
# Available flow control options: "none", "software", "hardware"

port = "auto"
baud = 9600
data_bits = 8
stop_bits = 1
parity = "none"
flow_control = "none"
timeout_ms = 500
reset_delay_ms = 1000
verbose = false
plot = false
plot_points = 100

Note

Note that the default baud rate is 9600, you can change it later on in the config file

The above default config file values can be overridden by using the flags (--auto, --port or -p, --baud or -r, --plot).

Features

• Read incoming Serial data from Serial ports
• Write to Serial port i.e Send data to Serial device.
• Basic logging.
• Auto detect Serial Ports
• Use a .toml file for config instead of flags
• Write serial data to a file for later use (can be .txt , .csv and more)
• Terminal based Serial Plotter (to be implemented with the --plot command)
• Plot multiple sensor values in the Serial Plotter with legends

Legends
