Hi guys, I’m new with PID code and let me know if i can help with some simple example, really want to know the logic of the code, I appreciate any help. 
thanks for your input, served me a lot, in the course of these days I reviewed the use of the LCD to select actions, the problem is we do not know how to store data, is there any code or file to store data previously selected?
If using robotC, use writeDebugStreamLine() then you copy/paste from the debugger window of the debug stream and parse in Excel/Open office (your spreadsheet tool of choice). Save, graph and analyze away from there!
It helps using a delimiter between variables and writing a header line at the beginning of the loop to make your life easier later on.
thank you very much 
, it is helpful to start making practices with ROBOTC
