altos: Time out reading packet data from cc1120 after 100ms

2013-01-11T05:44:18+00:00

Sometimes the radio will give a spurious wakeup indicating that a preamble seems to have arrived, but no packet data will appear. In this case, abandon the packet reception and go back to waiting for a preamble again. This releases the SPI bus for other users and also avoids missing packets. Signed-off-by: Keith Packard

Allow CC1120 to sit on other SPI busses

2012-12-31T22:22:37+00:00

Reading the incoming data bypasses the SPI API and touches the SPI data register directly; which port that is needs to be specified in the pins file Signed-off-by: Keith Packard

altos: Fix cc1120 debug code to build on megadongle

2012-12-29T02:34:33+00:00

RDF function had changed, and APRS isn't available on megadongle. Signed-off-by: Keith Packard

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: 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

altos: Fix aprs test to not allow callsign configuration

2012-12-08T01:38:17+00:00

There's no configuration to take a callsign from... Signed-off-by: Keith Packard

altos: Use configured callsign in APRS packets

2012-12-08T01:20:02+00:00

Instead of hard-coding my own call sign... Signed-off-by: Keith Packard

altos: Make APRS interval configurable

2012-12-08T01:18:32+00:00

This provides a separate configuration value for APRS, allowing the interval between APRS reports to vary. Signed-off-by: Keith Packard
