Change PID #defines to variables

[rwilbur]

We will need to change the PID #defines to variables so they can be changed via the communications to the raspberry pi

Indeed. Was planning on making possible to set those too. Maybe create some kind of "engineering/debug" mode on the interface module so that we can play with these values directly that's protected from a typical user.

That makes sense. I am pretty sure that all these will need to be set in the UI but open to a user since nurses and doctors will need to be changing all of these based on the patient and their progress.

#define INSPIRE_TIME 1600
#define INSPIRE_RATE 1
#define PIP 142
#define INSPIRE_DWELL 800
#define INSPIRE_DWELL_PRESSURE 140
#define EXPIRE_TIME 1000
#define EXPIRE_RATE 1
#define PEEP 130
#define EXPIRE_DWELL 600

Perhaps with these we won't have these values being set directly but have it be a certain unit on the display and it gets converted to whatever these units are in the command.

I was thinking of an engineering mode for the parameters for the PID for example, I don't think the medical personnel should have access to these. Same for any potential calibration parameters.
