A simple logging framework for Arduino.
This is designed to log variables in real time and then when requested print them on the serial bus in CSV format.
At that point using copy paste the data, can be visualised in your viewer of choice. This step could be automated at some point.
Any tabular program like excel will work, but I use Flow CSV viewer which just graphs.
Note, it can only take strings, so you need to convert whatever you want to log to a string first.
Create an instance of the class at the top of your sketch. You need to pass it the name of the file and the header of the file.
So if you wanted to create an object that is called "log01" to log VAR01 - 03 and call it "NAME", with a 1000 line ring buffer you'd do this
logger log01("NAME","VAR01,VAR02,VAR03",1000);
Then you just make a string of the data to log, adding the delimator that you want, I've used a comma:
String log = String(var01) + "," + String(var02) + "," + String(var03);
And pass it to log01:
log01.data(log);
To dump the data to the serial bus you would:
log01.read();
and you would get something like this on the serial bus:
*************************filedump requested: NAME TIME,VAR01,VAR02,VAR03 16847,159,318,477 16947,160,320,480 17047,161,322,483 17147,162,324,486 17247,163,326,489 17347,164,328,492 17447,165,330,495 **************************filedump ended NAME
Then just copy paste this into your view of choice.
