altos: Wire up another CC1120 GPIO to get MARC status changes

2012-12-17T00:04:05+00:00

When the radio drops out of RX or TX mode due to an error, it changes the MARC status, and sends pulse down a configured GPIO. Use this to tell when something 'bad' happened during TX or RX so that we can recover from losing the SPI bus in the middle of transmission or reception. Without this, the radio would change state and we'd never know, leaving the radio code waiting for an interrupt that would never arrive. Signed-off-by: Keith Packard

altos: Test APRS rounding by using coordinates near the boundary

2012-12-16T21:31:45+00:00

This selects lat/lon and altitude near the rounding boundary to check that the resulting APRS data is correctly computed. Signed-off-by: Keith Packard

altos: Document what HAS_BOOT_RADIO does in the m25 driver

2012-12-16T21:30:20+00:00

HAS_BOOT_RADIO causes the m25 driver to abort any ongoing receive in case that is holding the SPI bus. Signed-off-by: Keith Packard

altos: Round APRS data correctly

2012-12-16T21:29:31+00:00

Apply rounding once at the start of the computation, then truncate after that. Signed-off-by: Keith Packard

altoslib: unconfigured radio frequency data is now -1, not 0

2012-12-16T21:25:54+00:00

This changed when AltosConfigData was cleaned up, so now frequency settings must check for positive numbers rather than non-zero. Signed-off-by: Keith Packard

doc: Add paragraph noting differences in JST polarity

2012-12-15T22:47:22+00:00

Looks like the 'standard' polarity for 3.7V lipos using JST connectors in RC aircraft is swapped from what Spark Fun uses. Note that in the docs to try and keep people from wrecking hardware. Signed-off-by: Keith Packard

Merge branch 'micropeak-1.1'

altoslib: Discard previous flight state on SN change

2012-12-15T03:28:49+00:00

A previous change discarded previous *telemetry* state, but failed to discard any previous overall flight state. This would reset some of the data fields, but wouldn't reset the GPS state and max measurements. Signed-off-by: Keith Packard
