Andrew Tridgell a7d6a26bec HAL_PX4: fixed auto-flow control
the 6 bytes written to break the radio out of bootloader broke
auto flowcontrol detection
2014-05-19 22:02:39 +10:00
Andrew Tridgell 320834a5e7 HAL_PX4: read from FRAM in 128 byte chunks (2nd try)
this time without the amazingly silly bug
2014-05-02 22:12:45 +10:00
Andrew Tridgell db6b96caa0 Revert "HAL_PX4: read from FRAM in 128 byte chunks"

2014-05-02 12:24:54 +10:00
Andrew Tridgell 5cd145a307 AP_HAL: added set_failsafe_pwm() API
this allows the PWM values for FMU firmware failure to be setup
2014-04-21 08:36:52 +10:00
Andrew Tridgell 6eee2421cc AP_HAL: removed RCInput valid_channels() and added new_input() and num_channels()
the valid_channels() method was inconsistently implemented between
boards, and served two quite different purposes. It is clearer as two
functions
2014-03-25 14:39:41 +11:00

this makes it easier to get the board voltage from any library,
without having to allocate another analog channel object
2014-02-14 21:25:38 +11:00
Andrew Tridgell 4e2e685d7a HAL_PX4: better fix for IFLOW on all ports
the tcsetattr() call fails to apply the baudrate if the port has no
RTS pin and we ask for IFLOW. So just make a separate call.
2014-02-12 17:47:23 +11:00
Andrew Tridgell b2cdd39a99 HAL_PX4: don't enable IFLOW on ports without flow control
this should have been harmless, but breaks the GPS on Pixhawk. This
disables it until we work out why.
2014-02-12 17:32:07 +11:00
Andrew Tridgell c93794999e HAL_PX4: remove an old conditional define 2014-02-11 15:58:25 +11:00
Andrew Tridgell 439a075b30 AP_HAL: added force_safety_off rcoutput function

used to set PWM on motors when disarmed
2014-01-15 22:25:50 +11:00
Andrew Tridgell 64fbadcc21 HAL_PX4: use eeprom on PX4 FMUv1 as well
this means we no longer store params on SD at all
2014-01-15 19:33:13 +11:00
Andrew Tridgell 376ab30366 HAL_PX4: disable rename of old parameter file for now
be nice to release candidate users

auto-upgrade from microSD
2014-01-14 12:46:26 +11:00
Andrew Tridgell e78e35f3bd HAL_PX4: try to use uppercase names on NuttX microSD card 2014-01-14 12:46:26 +11:00

the number of channels could be zero with thread switch at the wrong
time
2013-12-31 22:25:16 +11:00
Andrew Tridgell a2997704eb HAL_PX4: removed code which drops throttle to 900 on loss of RC
rely on vehicle code checking for last data coming in
2013-12-31 10:58:49 +11:00
Andrew Tridgell ea649e036b AP_HAL: added HAL_CPU_CLASS define for selecting algorithms
this will make it easier to select the appropiate level of algorithm
for a CPU
2013-12-31 10:28:37 +11:00
Andrew Tridgell a95868e124 HAL_PX4: even larger tx buffer size for faster log transfer 2013-12-28 16:01:48 +11:00

Andrew Tridgell 24d1cf3bd6 HAL_PX4: don't check USB for data if not connected 2013-11-05 14:41:42 +11:00
Andrew Tridgell 8dc6b758f3 HAL_PX4: switch to delay_microseconds_semaphore() for UART timer
this may prevent some timing jitter on the GPS UARTs
2013-11-05 14:41:24 +11:00
Andrew Tridgell 5800c2a2c8 HAL_PX4: prevent excessive writes on startup from blocking
this could cause copter on PX4 to hang on startup
2013-10-28 16:12:44 +11:00
Andrew Tridgell 622f0dcc1d HAL_PX4: prevent threads running before subsystems are initialised
this fixes a bug where the timer thread would hang waiting for the
console on startup. This caused the "hit enter" behaviour with recent
PX4 bugs, as AnalogIn tried to read from fd==0, which was a console
read
2013-10-26 18:12:35 +11:00
Andrew Tridgell 34cde1a640 HAL_PX4: implement set_system_clock() 2013-10-24 14:22:48 +11:00
Andrew Tridgell 1c091cbca5 HAL_PX4: fixed a scheduler bug that affects UART IO
we need to detect if we are in a timer task using a PID, not a
flag. This is the same type of bug I fixed last week, but now fixed
properly.

The bug could well be the "USB bug" that Craig has been chasing
2013-10-19 16:50:38 +11:00
Andrew Tridgell d973730b88 HAL_PX4: use hrt timer and semaphores to improve timing

2013-10-13 12:43:25 +11:00
Andrew Tridgell 63bee0b2d8 HAL_PX4: disable checks for in_timerprocess
these are not valid in this form for the way the timer thread works on
PX4.
2013-10-11 16:06:35 +11:00
Andrew Tridgell 67db1cedaa HAL_PX4: fixed delay_microseconds() on PX4
we could underflow and delay a very long time!
2013-10-08 17:31:15 +11:00
Andrew Tridgell 7cab8cb3bb HAL_PX4: removed Console driver 2013-10-05 18:33:07 +10:00

Andrew Tridgell a5b29f44d5 AP_HAL: added hal.gpio->usb_connected() function
this replaces the USB_MUX_PIN on APM2, and works on PX4 and FMUv2
2013-09-19 16:23:40 +10:00
Andrew Tridgell 2990359043 PX4: Implement accurate ratiometric voltage reading on Pixhawk
this uses the monitoring of the 5V rail to compensate for changes in
the 5V reference versus the 3.3V ADC reference. It reduces the noise
on ratiometric sensors by a factor of about 6x.
2013-09-13 10:48:57 +10:00
Andrew Tridgell 3a3cecf5ff PX4: support getting servorail voltage from ORB 2013-09-12 16:28:06 +10:00
Andrew Tridgell fb56feb6b2 HAL_PX4: support all analog input pins, with scaling

2013-08-30 13:01:34 +10:00
Andrew Tridgell 9b3c54fc39 PX4: ensure storage buffer is DMA aligned
this helps for boards which use DMA for FAT IO
2013-08-30 13:01:33 +10:00
Andrew Tridgell 2340bb6220 PX4: use a minimum transmit buffer for UARTs of 512 bytes
this avoids writes stalling on the GPS port. We can't afford this
memory on APM2, but we can on PX4, and it means that while the GPS is
blocking at startup it doesn't cause any scheduler slips
2013-08-30 13:01:33 +10:00
Andrew Tridgell e5f19e314d PX4: systemreset() now takes a boolean argument
