Andrew Tridgell fc8065b50f HAL_PX4: added UART performance counters 2013-01-24 15:04:57 +11:00
Andrew Tridgell 6cf1d5e1ff HAL_PX4: handle IO errors on microsd 
this should handle EINTR gracefully
 2013-01-24 15:04:57 +11:00
Randy Mackay 542e2e1358 AP_PerfMon: fixes to make it work under AP_HAL (almost) 2013-01-23 21:22:17 +09:00
Andrew Tridgell 966b9b9b9c HAL_PX4: format panic messages with a newline 2013-01-23 16:54:44 +11:00
Andrew Tridgell c9799fb2b7 HAL_PX4: writing more than 512 bytes at a time can cause IO errors 
the vfat fs in NuttX is really very picky!
 2013-01-23 16:54:44 +11:00
Andrew Tridgell 952df2fced HAL_PX4: new buffered storeage driver for microsd cards 
this does all IO in the timer thread, avoids writes that don't change
data, and does all writes in multiples of 128 byte chunks. This should
be about as friendly to SD cards as we can get.
 2013-01-23 16:37:40 +11:00
Andrew Tridgell f72b532405 HAL_PX4: ensure all writes go via buffers 
this prevents output corruption by direct fd writes
 2013-01-23 09:22:51 +11:00
Andrew Tridgell 2a10727902 HAL_PX4: run timer thread as SCHED_FIFO 
this ensures it never yields to the main thread, which would break our
locking assumptions
 2013-01-23 09:21:50 +11:00
Andrew Tridgell 930e79a9e1 HAL_PX4: fixed rcin->valid() for RC override input 2013-01-23 07:57:59 +11:00
Andrew Tridgell 06e63d3167 HAL_PX4: use pthread_yield() in main loop 
this lowers the latency of the main loop somewhat
 2013-01-23 07:36:13 +11:00
Andrew Tridgell 6e8501603c HAL_PX4: avoid RCOutput ioctl unless values change 
this lowers latency somewhat
 2013-01-23 07:29:59 +11:00
Andrew Tridgell 89cb3fbd61 HAL_PX4: fixed blocking IO in UART driver 2013-01-22 21:52:21 +11:00
Andrew Tridgell 6ffa18fa61 HAL_PX4: rewrite UART driver to be much more efficient 
this does the IO in the timer thread, and uses buffers in the main
task to avoid system call costs in the flight code.

The cost of PX4 read and write system calls is quite high - about 10
to 15 usec. We can't afford to pay that per byte
 2013-01-22 21:22:01 +11:00
Andrew Tridgell 37be83994f SITL: allow motor multiplier to work on quad simulation 2013-01-22 21:22:01 +11:00

Jonathan Challinger 6565d83e73 InertialNav: Fixed signs, remove body-frame rotation, apply correction at 100hz. 2013-01-22 18:37:45 +09:00
Andrew Tridgell 546ed19ffc HAL_PX4: improved efficiency of serial writes 
use buffer at a time writes when possible, and use O_NONBLOCKING to
avoid txspace()
 2013-01-22 10:50:26 +11:00
Andrew Tridgell 18cfd29f2f HAL_PX4: added a read buffer to the UART driver 
this lowers the average cost of reading bytes by a large amount, and
prevents the GPS driver from chewing lots of time.
 2013-01-22 10:34:04 +11:00
Andrew Tridgell db0bd86317 HAL_PX4: name the eeprom file after the sketch

 2013-01-21 21:51:32 +11:00

bit slow

 2013-01-21 13:55:06 +11:00

Andrew Tridgell e852d6300f AP_HAL_AVR: fixed multi-channel RC output 2013-01-16 14:21:55 +11:00
James Bielman 4fa7bb1486 Add AVR compatibility header for missing math.h definitions. 
- Define float versions of math functions to the double versions
  on AVR (eg. #define sinf sin).
