UART inheritance mystery
Posted: Thu Nov 29, 2018 9:10 am
A "What a Terrible Failure"-moment (a.k.a WTF) for me...
I am developing a set of classes to be used with terminals. I am deriving from UART as follows:
The objective is, to create an object with the port and speed, and the lines and columns the terminal has.
I this example, port 6, speed 9600 baud, 80 columns and 25 lines. The last two values shall be stored in the serialTerminal object.
However, what happens, is this:
What am I overlooking here? Thanks for your help.
I am developing a set of classes to be used with terminals. I am deriving from UART as follows:
Code: Select all
from pyb import UART
class serialTerminal(UART):
def __init__(self,port,speed,maxCol,maxRow):
self.maxCol = maxCol
self.maxRow = maxRow
troubleTerminal = serialTerminal(6,9600,80,25) # this is line 61I this example, port 6, speed 9600 baud, 80 columns and 25 lines. The last two values shall be stored in the serialTerminal object.
However, what happens, is this:
I have read the documentation about inheritance in Python, also about usage of super and __init__. And i also invested hours in searching Google, but so far I don't understand, why the system obviously passes on the maxCol and maxRow parameters to the base class.Traceback (most recent call last):
