Controller software #7

Open racleave opened 4 years ago

racleave commented 4 years ago

This is an issue to deal with design of the controller software, and which hardware it has to interface to. Specific bugs should have their own issues.

We are using a Raspberry Pi 3B+ with a separate LCD screen.

The software has to read various sensors and control 2-6 valves. It also has to have at least two major modes:

  1. Timed breathing
  2. Patient triggered breathing, with a timed override

There are many variations on these modes, but keeping things simple at this stage is a must.

Here are some is a plot of typical pressures and times (lots more on the web):

I will set up the raspberry pi here and see how to get @hammockman logged into it. Any preferred OS? I'll go with Raspbian if not.
