altos: Clean up radio CRC handling

2012-06-28T00:17:44+00:00

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

altos: Optimize FEC encode and decode

2012-06-27T06:11:10+00:00

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

altos: rename ao_viterbi.c to ao_fec_rx.c

2012-06-27T05:16:44+00:00

Keep it parallel with ao_fec_tx.c Signed-off-by: Keith Packard

altos: Incremental viterbi decode

2012-06-25T13:51:36+00:00

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

altos: Get cc1120 packet reception working

2012-06-25T12:03:34+00:00

Interrupt-per-bit, but it seems to work Signed-off-by: Keith Packard

altos: improve FEC apis to reduce data copying

2012-06-23T23:05:42+00:00

Integrate interleaving and whitening into encode and decode steps. Add CRC checking function for receive. Make ao_fec_test program round-trip the data and verify correctness. Signed-off-by: Keith Packard

altos: Make ao_fec_tx_test build cleanly with -Wall

2012-06-23T09:13:52+00:00

Signed-off-by: Keith Packard

altos: Add the simplest possible viterbi decoder

2012-06-23T06:12:02+00:00

I think I understand how it works now. It's not exactly speedy, and it uses a lot of memory. Signed-off-by: Keith Packard

altos: Software implemenation of CC1111 radio encoding

2012-06-17T23:17:00+00:00

Add CRC, whitening, FEC and interleaving routines for transmission path to allow cc1120 to send telem packets to cc1111. Signed-off-by: Keith Packard

altos: Make telescience-v0.1 build with new ao_data struct
