altos: Require SPI speed to be declared for cc1200

2017-02-20T19:16:52+00:00

The cc1200 can't run SPI faster than 10MHz, so make sure every device picks a SPI clock slower than that. Signed-off-by: Keith Packard

altos: Expose cc1200 radio test functions for telemini bringup

2016-07-27T20:24:57+00:00

This exposes the cc1200 radio test function so we can load special test firmware in telemini to do the radio cal as it has no USB to perform that interactively. Signed-off-by: Keith Packard

altos: cc1200: use FIFO threshold pin output for APRS buffering

2016-06-30T02:17:45+00:00

Instead of polling the device for fifo space, just use the available pin configuration to figure out if there is enough space for a single APRS buffer. Then set the APRS buffer size to match the fifo threshold setting in the chip so that we know we can write the whole APRS buffer once the pin says there's space. Signed-off-by: Keith Packard

altos: Support telefire products in cc1200 driver

2016-04-20T03:21:30+00:00

Need to disable the pad code while testing the radio. Signed-off-by: Keith Packard

altos: Support 32MHz xtal on cc1200

2015-05-19T17:17:01+00:00

I ended up building some cc1200-based boards with 32MHz xtals, so just make this an option when building the driver. 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/cc1200: With PQT wide open, we can't use PQT_REACHED for start

2014-11-24T02:56:40+00:00

Because we're allowing even signals only weakly correlated with the preamble through to sync detection, we can't use the PQT_REACHED symbol to tell when a packet header has been seen. Instead, just look for SYNC_FOUND. Signed-off-by: Keith Packard

altos/cc1200: Wait for packet to be placed in FIFO during receive

2014-11-24T02:31:15+00:00

This changes the receive code to use MCU_STATUS, waiting for MARC_STATUS1 to indicate that the packet is in the fifo before reading it out. It also fixes the receive timeout code to keep receiving if the preamble or sync have been seen when the timeout fires. This makes TeleLCO able to use short timeouts during scanning while still successfully receiving packets. Signed-off-by: Keith Packard

altos: Reset interrupt flags before TX in CC1200 driver

2014-11-07T04:04:47+00:00

Failing to reset the flags set during interrupt leads to short-circuiting transmission and not a lot of packets going out. Signed-off-by: Keith Packard
