altos: Parameterize altitude table access and initialization2012-10-12T20:59:50+00:00Keith Packardkeithp@keithp.com2012-10-12T20:59:50+00:00urn:sha1:68308908afbd1f04b17056d2be408c89b3578c86
This allows projects to store the altitude data in different
representations or with different access modes.
By default, altitude data is stored in meters, but the initializers
include decimeter values so those can be used instead if desired.

This improves the computation of the table enough that errors from a
470 entry table are almost all < 0.5m.

Add CRC, whitening, FEC and interleaving routines for transmission
path to allow cc1120 to send telem packets to cc1111.

The linker is supposed to do this, but it ignores the static
initializer data added after the code.

altos: Check pdata+xdata memory usage during build2011-11-13T02:37:53+00:00Keith Packardkeithp@keithp.com2011-11-13T02:37:53+00:00urn:sha1:ef7f86453d686a49882e8c1b88a59228c4c631a9
The sdcc linker doesn't check the sum of pdata+xdata memory usage, it
only ensures that xdata itself is small enough. This doesn't keep
xdata below the end of usable ram on the cc1111 though (0xfe000).
Fix up the check-stack program to also make sure all of xdata fits in
available memory.

altos/avr: Must leave space for init stack in ram2011-10-12T00:57:32+00:00Keith Packardkeithp@keithp.com2011-10-12T00:45:51+00:00urn:sha1:b80f8ffb61566cbd134c399ea6ccf9290075490b
The stack used during system initialization lives at the top of RAM,
so leave some space for that.
