altos: Set APRS deviation to 3kHz

2013-05-08T03:08:01+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

altos: Make sure the packet format is set reasonably for radio test

2013-04-12T10:09:16+00:00

Dunno if this matters, but it might as well be set reasonably Signed-off-by: Keith Packard

altos: Try RDF mode for TX calibration

2013-04-07T06:48:36+00:00

Trying to get the radio to stop modulating the carrier when calibrating the radio, we'll try RDF mode which says no preamble or sync data. This might shift the frequency though? Signed-off-by: Keith Packard

altos: Horrible kludge -- disable radio while talking with SD card

2013-04-01T09:39:35+00:00

The SD card really doesn't like the RFI generated by our enormous radio, so just lock the radio out while working with the card. Signed-off-by: Keith Packard

altos: Disable CC115L debug commands

2013-03-31T19:21:03+00:00

now that it appears to work, leave these disabled by default Signed-off-by: Keith Packard

altos: Lock cc115l radio mutex when using global radio values

2013-03-30T08:31:12+00:00

This moves the locking up above the global state variable uses so that multiple radio users (as if we had any) won't collide. Signed-off-by: Keith Packard

altos: Configure cc115l sync byte count for each radio mode

2013-03-30T08:30:18+00:00

two sync bytes for packet mode, disable sync for rdf/aprs mode. Signed-off-by: Keith Packard

altos: Get CC115L radio working.

2013-03-30T00:05:36+00:00

This involved figuring out which GPIO signal would reliably indicate that the transmitter was finished; I ended up using the PA_PD bit for this. This also converts all of the radio users to the long packet support as the CC115L has only a 64-byte fifo, not large enough to hold either an RDF tone or a regular AltOS telemetry packet. This also renames the public API for sending APRS packets from ao_radio_send_lots to ao_radio_send_aprs, which is at least more accurate. The workings of that API haven't changed, just the name.

altos: Add temporary RF power settings

2013-03-29T19:13:59+00:00

These expose the raw cc115l and rfpa0133 register settings so that we can calibrate them against measured power outputs. I've tested them to verify that they change how much power the board consumes, so they're clearly doing something... Signed-off-by: Keith Packard

altos: Improve CC115L driver. Generates carrier now.

2013-03-26T21:25:48+00:00

Still no data, but at least the carrier comes up on frequency now. Signed-off-by: Keith Packard
