0bc8f551de Use matched filter for AIS GMSK demodulation demo. 
Less than optimal for plain FSK, but flexible enough to also support GFSK/GMSK. Not at all optimized for SIMD instructions, so may not perform adequately at Bluetooth/GSM rates.

a9c190b6bb Matched filter implementation. 
Essentially a complex FIR filter that's more flexible than the ones already in the code base. Refactor?!

9a3454d695 Touch code cleanup, stop scanning when no touch.

Jared Boone
d8b3b4cb6b Check queue empty only once when reading messages. 
There was a second is_empty() call hidden in the pop() call, so the while(condition) was redundant.
 2015-08-27 14:27:29 -07:00

035ec84f04 Wrap MessageQueue.push() with mutex. 
This addresses issue #61, occasional FIFO/data corruption. With the mutex, any thread on one core can write to the FIFO. But still, only one thread on one core should read from the FIFO.
 2015-08-26 14:18:03 -07:00
Jared Boone
7937ea7327 Enable DMB instruction at end of FIFO data copy.

e9c47ff91a Remove M0 ldscript NVRAM region.
