altos: Set APRS deviation to 3kHz

2013-05-06T23:08:52+00:00

I finally found a bunch of references to APRS on the net and they all appear to assume a 3kHz deviation. Let's see if this works better with Yaesu radios. Signed-off-by: Keith Packard

Revert "altos: Make APRS deviation configurable"

2013-05-06T23:04:02+00:00

This reverts commit a18d68da1b0b23a6089166fcd14a5bb5368f10f1. We're just going to use 3kHz for APRS

altos: Make APRS deviation configurable

2013-05-03T07:52:30+00:00

Maybe this will help the Yaesu VX-8GR receive our packets Signed-off-by: Keith Packard

altos: Reduce stack usage of FAT driver and logger

2013-05-01T01:57:53+00:00

Move some large stack arrays to static storage. Also eliminates some printf error messages which don't seem that useful except for debugging. Signed-off-by: Keith Packard

altos: Make cc1120 driver return false on recv timeout

2013-04-30T07:05:33+00:00

Was returning an uninitialized value, which was often not zero Signed-off-by: Keith Packard

altos: Reconfigure CC1120 receiver to match our usage

2013-04-30T06:53:43+00:00

Open up the AGC to the full range. Set the AGC ref based on our receive BW (100kHz). Use the previous AGC value as the first guess for the next receive. Signed-off-by: Keith Packard

altos: Compute "real" RSSI value in radio code as needed

2013-04-30T06:20:25+00:00

Instead of dragging around the weird CC1111 RSSI values, just compute a dBm value in a signed 8-bit integer, ao_radio_rssi. Use that everywhere we need RSSI internally. We leave the weird CC1111 value in the packet reply as that's what the host expects. Signed-off-by: Keith Packard

altos: Allow LCD segments to not be multiplexed across digits

2013-04-29T06:08:03+00:00

This allows each LCD segment to be individually configured as to which COM and which SEG drives it, permitting maximum flexibility in wiring. Signed-off-by: Keith Packard

altos: Clear any broken cc1120 TX fifo bits before transmitting

2013-04-29T06:05:18+00:00

This just goes and clears the transmitter before using it, just in case it got wedged somehow. It also clears the bits while waiting for the radio to go idle, otherwise it'd never make it. Signed-off-by: Keith Packard

altos: Make cc1120 driver wait for TX finished

2013-04-29T06:03:57+00:00

Otherwise, we may come in and try to use the radio again too quickly, causing it to go into a TX fifo error state. This change watches the MARC status until the transmitter is explicitly marked as finished. Signed-off-by: Keith Packard
