The following are 7 code examples for showing how to use serial.PARITYODD. These examples are extracted from open source projects. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example. You may check out the related API usage on the sidebar. To get a list of available serial ports use. Python -m serial.tools.listports at a command prompt. From serial.tools import listports listports.comports # Outputs list of available serial ports from the Python shell.
Opening serial ports¶
Open port at '9600,8,N,1', no timeout:
- Here are the examples of the python api pexpect.TIMEOUT taken from open source projects. By voting up you can indicate which examples are most useful and appropriate. By voting up you can indicate which examples are most useful and appropriate.
- To get a list of available serial ports use. Python -m serial.tools.listports at a command prompt. From serial.tools import listports listports.comports # Outputs list of available serial ports from the Python.
Open named port at '19200,8,N,1', 1s timeout: Plug and play for macbook.
Open port at '38400,8,E,1', non blocking HW handshaking:
Configuring ports later¶
Get a Serial instance and configure/open it later:
Also supported with context manager:
Readline¶
Be careful when using readline(). Do specify a timeout when opening theserial port otherwise it could block forever if no newline character isreceived. Also note that readlines() only works with a timeout.readlines() depends on having a timeout and interprets that as EOF (endof file). It raises an exception if the port is not opened correctly.
Do also have a look at the example files in the examples directory in thesource distribution or online.
Note
The eol parameter for readline() is no longer supported whenpySerial is run with newer Python versions (V2.6+) where the moduleio is available.
EOL¶
To specify the EOL character for readline() or to use universal newlinemode, it is advised to use io.TextIOWrapper:
Testing ports¶
Listing ports¶
python-mserial.tools.list_ports will print a list of available ports. Itis also possible to add a regexp as first argument and the list will onlyinclude entries that matched.
Note
The enumeration may not work on all operating systems. It may beincomplete, list unavailable ports or may lack detailed descriptions of theports.
Accessing ports¶
pySerial includes a small console based terminal program calledserial.tools.miniterm. It can be started with python-mserial.tools.miniterm(use option -h to get a listing of all options).
