I do a lot of work with serial comms TeraTerm is an excellent serial terminal, but sometimes a customised application is required, for example when dealing with binary data. If you do put my script to use or enhance it, i’d be interested to see what features you add.A simple demonstration of threading in PyQt I do a lot of work with serial comms TeraTerm is an excellent serial terminal, but sometimes a customised application is required, for example when deal…Ī simple demonstration of threading in PyQt You may notice that this script is an updated version of one I wrote about before ( here) which I used to communicate with the Arduino MiniPirate sketch. The Pinguino IDE does not have a serial monitor built in so my script can be used for that sometimes needed functionality. For example:Īlso note that the Arduino IDE has a built in serial monitor (the newer versions have a serial plotter too) so that serial communications with your Arduino is relatively easy during code development. using virtual terminals in a login session), it can be used as a serial terminal communication program too. Although screen is primarily used as a terminal multiplexer (i.e. Perhaps the most common one used is minicom.

With this script you have basic serial port communications (quite usable) and it can be easily added to for enhanced functionality.Īgain, there are other serial communication programs/scripts (which run under Linux). Note that the comments tell you how to change certain features of the program. When running, the script will ‘echo’ any characters coming from the serial port to the console and ‘echo’ any characters typed in from the console to the serial port.

If you give it both parameters, they can be in any order as the script can tell what is a port versus what is the rate. If you want to override or specify either the serial port or BAUD rate just give it either or both parameters. Given no parameters, it defaults to 115200 BAUD and will search for ‘active’ serial ports with the name /dev/ttyUSB* or /dev/ttyACM* and use the first one it finds. # Uncomment the next two lines to display the typed in characters in hex format

# for x in line: print ('%s') % (x.encode('hex')), # Uncomment the next line to display the input from the serial port in hex format

Ser = serial.Serial(port=serport,baudrate=rate,parity=serial.PARITY_NONE,stopbits=serial.STOPBITS_ONE,bytesize=serial.EIGHTBITS,timeout=1) Print 'Unable to find any ports scanning for /dev/' + dev
