altos/cc1111: Use SW to drive UART RTS pin

2016-05-09T18:33:48+00:00

Can't get the hw to work. Signed-off-by: Keith Packard

altos: Add ao_gpi_set/clr_bits functions

2016-04-13T13:17:06+00:00

These set or clear a group of bits in a single GPIO register all together. Signed-off-by: Keith Packard

altos: Replace ao_alarm/ao_clear_alarm with ao_sleep_for

2015-02-14T07:51:10+00:00

Having arbitrary alarms firing in the middle of complicated device logic makes no sense at all. Therefore only correct use of ao_alarm and ao_clear_alarm was around a specific ao_sleep call, with correct recovery in case the alarm fires. This patch replaces all uses of ao_alarm/ao_sleep/ao_clear_alarm with ao_sleep_for, a new function which takes the alarm timeout directly. A few cases which weren't simply calling ao_sleep have been reworked to pass the timeout value down to the place where sleep *is* being called, and having that code deal with the return correctly.

altos: Declare port register type only in arch header

2014-11-06T23:58:42+00:00

Instead of defaulting to 8 bits, explicitly require declaration of the type of the port register for each architecture. Signed-off-by: Keith Packard

altos: Reduce deviation at 2400/9600 baud

2014-09-07T03:39:37+00:00

There's no reason to use 20.5kHz deviation at 2400 and 9600 baud, and if we get a better receiver, we'll want to use narrower deviation to have less bandwidth sucking noise into the radio. The new values are (nominally) 5.125kHz deviation for 9600 baud and 1.5kHz deviation for 2400 baud. Signed-off-by: Keith Packard

cc1111: Wait for internal flash write to complete

2014-08-18T03:57:16+00:00

This ensures that we don't try to start another write too soon. Signed-off-by: Keith Packard

altos: Use 32-bits for flight state data (alt/speed/accel)

2014-07-11T00:35:44+00:00

Stores 32-bits for all of the flight parameters. Uses 64-bit intermediates for kalman computation. Signed-off-by: Keith Packard

altos: Extend GPS altitudes to at least 24 bits everywhere

2014-07-11T00:35:44+00:00

Telemetry gets a special 'mode' flag indicating that 24-bit data is present; log files get new data and log readers are expected to detect that via the firmware version number. Signed-off-by: Keith Packard

altos: Rework packet receive for cc1120

2014-07-05T07:38:10+00:00

Instead of blocking on PQT, just set up the receiver to start going and when the first bit interrupt comes in, grab the SPI bus if possible and configure it for reception. This improves sensitivity in the radio by a significant amount while making the code conceptually a bit nicer. Signed-off-by: Keith Packard

altos/cc1111: Add 2400 and 9600 baud telemetry rate support
