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

altos: Use configured callsign in APRS packets

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

altos: Fix up APRS packet sending code in cc1120 driver

2012-12-07T18:15:25+00:00

This fixes the FIFO management, ensuring that the data are streamed into the radio fast enough to keep the packet continuous. Sounds like it works, but testing with an actual APRS receiver is required. Signed-off-by: Keith Packard

Merge branch 'master' into aprs

altos: fix functions calling pollchar to use 'int' to hold the value

2012-12-07T18:12:19+00:00

AO_READ_AGAIN doesn't fit in a char anymore now that stdio is 8-bit clean, everyone using pollchar must use an 'int' variable to capture the whole value from pollchar. Signed-off-by: Keith Packard

altos: Hook up APRS to telemetry loop

Send APRS packet once every 2 seconds Signed-off-by: Keith Packard
