I’m trying to translate the following code to C++:
https://github.com/JohanLink/Ball-Balancing-PID-System/blob/master/pythonCodes/interface.py
I wanted to understand what the following line does:
ser.write((str(dataDict[(alpha,beta)])+"\n").encode())
5
All right, let’s go
ser.write() is for "write" on serial port.
str() is to convert the value to string.
dataDict[] is a dictionary.
"\n" is to skip a line.
encode() is to convert to a set in bytes
In short, this section tells the serial the result of the conversion str() from the dictionary concatenated with a line break, converted into bytes.
Note: The function .write() only works with bytes, so the need for the .encode(), and this only works with strings, so the str()

I think you’re just sending out a dictionary value associated with the key
(alpha, beta)+ the breaking of lines, but I may be wrong.– Anthony Accioly
Yes, so it’s a dictionary

What I mean is that your answer gives the impression that the entire dictionary is being converted to a string: Instead of writing "a conversion
str()dictionary concatenated with a line break" I would use "a conversionstr()of the value associated with tuple(alpha, beta)in the dictionarydataDictconcatenated to a line break". It makes sense?– Anthony Accioly
