mjb/altos/src/cc1111, branch 1.4.9.1AltOS - the operating system for Altus Metrum products
https://git.ethernal.org/mjb/altos/atom?h=1.4.9.12014-07-05T07:38:10+00:00altos: Rework packet receive for cc11202014-07-05T07:38:10+00:00Keith Packardkeithp@keithp.com2014-07-05T07:04:06+00:00urn:sha1:292cb8380b478542555b5f370e8252eafa2f74ac
Instead of blocking on PQT, just set up the receiver to start going
and when the first bit interrupt comes in, grab the SPI bus if
possible and configure it for reception. This improves sensitivity in
the radio by a significant amount while making the code conceptually a
bit nicer.

altos/cc1111: Add 2400 and 9600 baud telemetry rate support2014-07-05T07:38:10+00:00Keith Packardkeithp@keithp.com2014-07-03T05:31:59+00:00urn:sha1:aba1703a1cff3da001d64bf2d15a591816e3350e

altos/cc1111: Adjust receive parameters to improve sensitivity2014-07-05T07:38:10+00:00Keith Packardkeithp@keithp.com2014-07-03T05:30:23+00:00urn:sha1:c20ddde2f9eb0ad8dbb982e9d0cbe91639160a34
This removes the packet quality test and carrier sense tests when
deciding whether to start decoding a packet. This lets more bad
packets through, but the CRC check catches those and now we're
regularly receiving packets down to -110 or even -112 dBm. Before this
change, we'd rarely see packets as low as -105dBm

altos: Call ao_telemetry_reset_interval when telemetry rate changes2014-07-05T07:38:09+00:00Keith Packardkeithp@keithp.com2014-07-05T07:09:25+00:00urn:sha1:ea5887027e7a39da2b7d84a142d74950b7a24703
This lets the radio code adjust the telemetry packet sending pattern
when the data rate changes.

altos: Report total available log space in version command2014-06-10T16:38:53+00:00Keith Packardkeithp@keithp.com2014-06-10T16:37:43+00:00urn:sha1:75df97b5f6ade3310618a477b685d39b7fd4666e
This provides a more accurate means of determining available log space
than guessing whether some portion of the flash chip holds
configuration data.

And, doesn't fit in memory for some of them, so don't compile it.

Errata http://www.ti.com/lit/er/swrz022c/swrz022c.pdf says that the
xtal is stable bit is bogus and that you need to just delay for a while.

altos: Add configurable beep tone2014-05-02T20:52:45+00:00Keith Packardkeithp@keithp.com2014-05-02T19:26:07+00:00urn:sha1:027b1470c7a2d007eaab5c8d49f772b0c7559b80
This lets you directly set the mid-range beep tone; the high and low
tones remain set off of that in the same ratio as before.
Note that none of the cc1111 products get this feature as they don't
have enough flash space anymore...

This works on everything with a beeper except TeleMetrum v1.0 which
just doesn't have enough flash space for the code.
