.. _rs232:
RS232 - Serial Port
===================
The ``RS232`` class provides a wrapper for basic UART functionality for RS232#1. |br|
It offers basic functions to configure, send and receive data.
The class needs to be initialized with the following parameters:
.. csv-table::
:header: Parameter name, Value, Description
:widths: 10, 10, 10
``uart_baudrate``, "9600, 19200, 38400, 57600,
115200, 230400, 460800,
921600", RS232#1 baudrate
Methods
-------
.. automodule:: rs232
:members:
:undoc-members:
:show-inheritance:
:exclude-members: UART_PORT
.. note::
Since the ``get_uart_id()`` method of the ``RS232`` class returns a microPython UART object, it has all its methods. |br|
To do not duplicate the documentation, we suggest to take a look at the `official microPython project documentation `_ to see what methods you can additionaly use.
Example of additional methods:
>>> import sbc
>>> rs232 = sbc.RS232( 115200 )
>>> print('There are: ',rs232.any(),' characters to be read')
There are: 1580 characters to be read
>>> print(rs232.get_uart_id().readline())
