Andrew Tridgell 8f2f4b1bc5 HAL_PX4: use write() to /dev/pwm_output for servo output
this lowest the cost of PWM output a lot, but relies on the new I2C
based IO firmware

Andrew Tridgell 9b4c75c66b RC_Channel: don't change trim if radio in is zero 2013-01-25 20:44:36 +11:00
Andrew Tridgell f9d43f4c3e HAL_PX4: prevent loop() overruns using hrt
this ensures if loop() takes more than 1 second, the main task gets
its priority dropped until loop() completes

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 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.

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

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

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.

Andrew Tridgell db0bd86317 HAL_PX4: name the eeprom file after the sketch

bit slow
2013-01-21 19:44:01 +11:00
Andrew Tridgell b9b3ef91a1 AP_Baro: added timer to PX4 driver

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).
- These macros appear to be missing in older versions of avr-libs.
- Include AP_Math.h rather than math.h to get these definitions.
2013-01-16 13:52:17 +11:00
