Andrew Tridgell	48247b6adc	HAL_PX4: minimise usage of hrt_absolute_time()	2014-08-20 09:10:24 +10:00
Andrew Tridgell	1241da466b	HAL_PX4: added millis64() and micros64()	2014-08-20 08:01:06 +10:00
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	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 ... this gives much more accurate microsecond delays, while also ensuring we yield the CPU when possible	2013-10-14 08:29:30 +11:00
Andrew Tridgell	942ae70651	HAL_PX4: updates for AP_HAL::MemberProc	2013-09-30 21:06:42 +10:00
Andrew Tridgell	7ec242146d	HAL_PX4: update for new scheduler API	2013-09-28 21:24:03 +10:00
Andrew Tridgell	fa107bdb58	PX4: moved UART handling to its own thread ... this prevents slow writes to the SD card from interfering with MAVLink or GPS serial communication	2013-09-04 13:15:27 +10:00
Andrew Tridgell	7082e0f8aa	AP_HAL: added hold_in_bootloader parameter to scheduler->reboot()	2013-09-04 11:58:13 +10:00
Andrew Tridgell	af7381e9e0	AP_HAL: added register_io_process() ... this is used to register a low priority IO task. Used for file IO in DataFlash_File.cpp	2013-04-17 21:33:50 +10:00
Andrew Tridgell	02c5c3ec4a	HAL_PX4: changed scheduler priorities ... put sensor priority above main sketch, to prevent occasional blocking for sensor data	2013-02-20 11:30:54 +11:00
Andrew Tridgell	d7409b6a25	HAL_PX4: startup in low priority to fix CLI ... this ensures that tight sensor loops in setup() can run without sleeping	2013-01-25 20:44:36 +11:00
Andrew Tridgell	70227d5d93	HAL_PX4: added scheduler performance counters	2013-01-24 15:04:57 +11:00
Andrew Tridgell	39e28d48c2	HAL_PX4: switched scheduler to use a pthread ... this allows the timer tasks to access file descriptors in the main APM task, which makes writing PX4 device drivers much easier	2013-01-21 13:54:09 +11:00
Andrew Tridgell	7c7a215934	HAL_PX4: fixes for new Scheduler API	2013-01-11 12:25:26 +11:00
Andrew Tridgell	c6305b5876	HAL_PX4: rework Scheduler using hrt calls ... thanks to Julian Oes for the suggestion	2013-01-03 13:15:57 +11:00
Andrew Tridgell	5a70f3becf	HAL_PX4: added a scheduler implementation	2013-01-02 21:39:26 +11:00
