Jared Boone
9a3454d695 Touch code cleanup, stop scanning when no touch. 
No need to change voltages on touch panel when no touch is detected. This should reduce noise a bit.

f1ca3fe5bb Switch RFFC5072, MAX2837 back to 40MHz reference.

19764ce693 Swap function of P2_8, P2_4 in schematic, firmware, CPLD.

b13081696d Simplify MessageQueue pop() usage. 2015-08-27 14:35:17 -07:00
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
Jared Boone
5d9079f87f Stop streaming when changing baseband configuration. 
Without, the baseband would get confused.

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. 
Can't hurt to make sure FIFO and buffer state are flushed before returning to caller...

dfe0bd7366 Generate SPI flash image with Python, not dd/cat/head. 
Addresses issue #42.
Windows users now stand a chance of being able to build an image, and all these zero-byte HackRF binary issues should go away.

e9c47ff91a Remove M0 ldscript NVRAM region. 
I misunderstood the documentation. It's not NVRAM (backed up by VBAT), it just survives a deeper core sleep than other RAM does.
 2015-08-20 16:03:14 -07:00
Jared Boone
52e8093618 Generalize FIFO to specify FIFO size as 2^K.
