Re: FDA Approval
The demo code has calls for delay function all over the places as well as Arduino libraries. The baseline code I am collaborating (code in UF github) had, until Yesterday, 180 microseconds max in its

Re: Wireless Connectivity to Ventilators via Android - Problems??
I kind of was initially. I have implemented BLE for several other projects and I was initially considering to use it to control our ventilator. However, it is not very practical. Imagine 10~20

That just doesn't seem like a good idea since external devices like that are pretty easily hacked. Why do they want it? Jack, W8TEE

Re: freeMemory()
That's fine, but I don't think we want the production version to include the runtime free memory checks in it, do we? If we do, then I would suggest wrapping all of its code in #ifdef DEBUG
