Transmit computed ground pressure and acceleration values

2009-05-18T06:36:21+00:00

These are the last two values relevant to figuring out the state of the flight computer, and as they are computed by averaging 10 seconds of 100Hz sample data, they're a lot more accurate than anything the receiver could do on its own. Signed-off-by: Keith Packard

Provide install target

USB device names can contain '.' too

2009-05-18T05:44:19+00:00

Depending on the hierarchy of devices, names can contain '.', so allow those too. Signed-off-by: Keith Packard

scandir returns -1 on error

In which case, the namelist is invalid, so don't look at it, and don't free it. Signed-off-by: Keith Packard

Send computed accel/vel/pres values over the radio

2009-05-18T05:29:54+00:00

These computed values reflect what the flight computer is actually refering to for state changes, and will be useful in debugging the flight software as well as provide a filtered view of the data. Signed-off-by: Keith Packard

Handle disappearing serial devices

2009-05-18T05:29:06+00:00

Put up a dialog when the serial open fails, and shut down monitoring when the serial device disappears while running. Signed-off-by: Keith Packard

While on the pad, zero out velocity every second

2009-05-18T05:24:53+00:00

We integrate acceleration to get velocity, but that means sitting on the pad for a long time can add substantial error to the velocity value. Each second, take the velocity value from a full second ago and subtract that out of the current velocity. Once we detect boost, this will stop, which means that as long as we detect boost within a second, we won't have subtracted out any "real" velocity. This keeps the pad velocity hovering around zero, which is pretty useful. Signed-off-by: Keith Packard
