usb-ser-mon.py

A serial monitor for USB Serial devices.

usb-ser-mon.py will automatically detect your connected USB Serial device and print the output from it.

This is similar in functionality to the Arduino serial monitor, except that usb-ser-mon.py deals with the device disconnects automtically, and will wait for your device to reconnect.

If you have more than one USB device connected, you can use the -s option to specify the serial number of the device you wish to connect to, or use the -n command to specify the device vendor.

Currently, this program only works under linux.

It was tested with the following devices:

  • Teensy 3.1
  • STM32F4DISCOVERY board
  • Prolific USB to Serial adapter

Use -l to list all of the connected devices.

./usb-ser-mon.py -l

will show you the currently connected devices, for example:

USB Serial Device with vendor 'Teensyduino' serial '21973' found @/dev/ttyACM1
USB Serial Device with vendor 'Prolific_Technology_Inc.' found @/dev/ttyUSB0
USB Serial Device with vendor 'STMicroelectronics' serial '00000000050C' found @/dev/ttyACM0

If you want to connect with the STM device (an STM32FDISCOVERY board in this situation), then you might do:

./usb-ser-mon.py -n Teensy

and then see:

USB Serial device with vendor 'Teensyduino' serial '21973' connected @/dev/ttyACM1

>>>

In the previous example the Teensy was already connected. If I unplug and replug the Teensy device then I'd see:

USB Serial device @ /dev/ttyACM1  disconnected.

Waiting for USB Serial Device with vendor 'Teensy' ...
USB Serial device with vendor 'Teensyduino' serial '21973' connected @/dev/ttyACM1
Done executing '/src/main.py'
Micro Python for Teensy 3.1
Type "help()" for more information.
>>>

You only need to use as many characters as are required to uniquely identify a device, so I could use ./usb-ser-mon.py -n STM to connect to the Discovery board.

Use Control-X to exit from usb-ser-mon.py.

The mk-udev-rules-stm32.sh script will create the appropriate udev rules for the STM32F4 series processors.

The mk-udev-rules-pyboard.sh script will create the appropriate udev rules for the MicroPython pyboard.

The mk-udev-rules-teensy.sh script will create the appropriate udev rules for the Teensy 3.1 board.
