* altos: Change CC1120 SPI speed to 4MHz.Keith Packard2013-01-13
| | | | | | | | Most of the chip can run at 8MHz, but extended register access is limited to 6.1MHz. Instead of pushing things, just run the SPI bus at 4MHz. Signed-off-by: Keith Packard <keithp@keithp.com>

| * Allow CC1120 to sit on other SPI bussesKeith Packard2012-12-31
| | | | | | | | | | | | | | | | Reading the incoming data bypasses the SPI API and touches the SPI data register directly; which port that is needs to be specified in the pins file Signed-off-by: Keith Packard <keithp@keithp.com>
* | altos: Time out reading packet data from cc1120 after 100msKeith Packard2013-01-10
|/ | | | | | | | | | Sometimes the radio will give a spurious wakeup indicating that a preamble seems to have arrived, but no packet data will appear. In this case, abandon the packet reception and go back to waiting for a preamble again. This releases the SPI bus for other users and also avoids missing packets.

* altos: Fix cc1120 debug code to build on megadongleKeith Packard2012-12-28
| | | | | | RDF function had changed, and APRS isn't available on megadongle. Signed-off-by: Keith Packard <keithp@gag.com>
* altos: Wire up another CC1120 GPIO to get MARC status changesKeith Packard2012-12-16
| | | | | | | | | | | | | 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 <keithp@keithp.com>
* altos: Fix up APRS packet sending code in cc1120 driverKeith Packard2012-12-07
| | | | | | | | 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 <keithp@keithp.com>
* altos: Hook APRS up to the radioKeith Packard2012-12-06
| | | | | | | This adds an arbitrary-length packet writing function to the radio code. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: fix cc1120 radio test - state wasn't made staticKeith Packard2012-11-18
| | | | | | so whether the radio got turned on was random. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Switch drivers to ao_arch_block/release_interruptsKeith Packard2012-10-25
| | | | | | Stop using cli/sei, which are avr-specific Signed-off-by: Keith Packard <keithp@keithp.com>

| | | | | | Add sample-based profiling, using a 1kHz timer Signed-off-by: Keith Packard <keithp@keithp.com>

* altos: Clean up radio APIsKeith Packard2012-08-27
| | | | | | | Move api to ao_radio_cmac.h include file. Expose ao_radio_test as standard API. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Place STM config values at fixed addresses for re-useKeith Packard2012-07-17
| | | | | | | | Just like cc1111, stick the serial number and radio calibration values at known fixed addresses so that when re-flashing the board, we can go find the existing values. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Create macros to convert from/to radio RSSI representationKeith Packard2012-07-11
| | | | | | | | AO_RSSI_FROM_RADIO and AO_RADIO_FROM_RSSI. Removes a bunch of open-coded versions of the same function. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Signal continuity over radio in pad mode (trac #40)Keith Packard2012-07-10
| | | | | | | This is especially useful for telemini which has no beeper, allowing you to hear the continuity signal while at the pad over the air. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Make profiling Viterbi decoder more usefulKeith Packard2012-06-27
| | | | | | | This blocks starting the decoder until all of the data have arrived so that the time spent in the decoder is easily computed. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Clean up radio CRC handlingKeith Packard2012-06-27
| | | | | | | Make the FEC code just set the CRC_OK bit like the cc1111 radio does; eliminates a bunch of weird conventions across the FEC API. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: include targe SPI speed in get requestKeith Packard2012-06-27
| | | | | | | STM needs it to be provided when enabling the SPI device, so just fix AVR and cc1111 to do the same. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Clean up cc1120 driver a bitKeith Packard2012-06-27
| | | | | | Make some variables static, remove stale debug code Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Optimize FEC encode and decodeKeith Packard2012-06-26
| | | | | | | | | | | | | Integrate interleaving, CRC and padding within the decode/encode functions. Provide for ISR priorities so that the 1120 RX interrupt takes precedence over the other interrupts or we risk losing bits. Optimize the viterbi decoder a bit (goes from 10ms per packet to 7ms per packet). Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Incremental viterbi decodeKeith Packard2012-06-25
| | | | | | | | Decode radio input one interleave block at a time. This overlaps the decode computation with the packet reception, leading to lower latency in an attempt to keep up with the transmitter. Signed-off-by: Keith Packard <keithp@keithp.com>

* altos: make cc1120 ao_radio_send re-entrantKeith Packard2012-06-17

* altos: Software implemenation of CC1111 radio encodingKeith Packard2012-06-17
| | | | | | | Add CRC, whitening, FEC and interleaving routines for transmission path to allow cc1120 to send telem packets to cc1111. Signed-off-by: Keith Packard <keithp@keithp.com>
