Andrew Tridgell 6836a986f3 PeriodicProcess: switch to SREG = oldSREG pattern for interrupt mask/restore 2012-11-20 22:31:23 +11:00
rmackay9 35cb7ff7e5 AP_PeriodicProcessStub: fixed build due to missing reference to _suspended 2012-09-29 14:41:25 +09:00
rmackay9 c007a19200 AP_PeriodicProcess: added running() method which tells the caller whether the timer is suspended or not 2012-09-29 13:47:55 +09:00
rmackay9 00e79e7915 AP_TimerProcess: added simple example sketch 2012-09-29 13:23:51 +09:00

Andrew Tridgell c8befe4536 AnalogSource: make the Arduino AnalogSource interrupt driven 
this fixes several problems with reading analog sources:

 - we were getting poor values because we didn't wait long enough for
   an analog source to settle

 - we wasted a lot of CPU cycles waiting for conversions

 - we were not taking averages over many samples, which we did with
   the old AP_ADC driver on the APM1

Andrew Tridgell 534aee17e9 TimerProcess: added suspend_timer()/resume_timer() 
this will be used to avoid races in driver initialisation

Randy Mackay ed19c25a97 Arduino 1.0 - changed all #includes of "WProgram.h", "wiring.h" and "WConstants.h to "Arduino.h". 
Modified FastSerial's write function to return size_t (number of bytes written).

Andrew Tridgell e7dab19260 TimerProcess: prevent a race in setting up the timer callbacks 2011-12-28 16:00:49 +11:00
Andrew Tridgell 4d71482d1c TimerProcess: check for duplicate registrations 
if a driver gets initialised twice, make sure it doesn't get called
twice in the timer loop
 2011-12-28 16:00:48 +11:00
Andrew Tridgell dbaa6fb6d2 TimerProcess: make some variables uint8_t 
save a couple of bytes
 2011-12-28 16:00:48 +11:00
Andrew Tridgell 79d6c21dde PeriodicProcess: added set_failsafe() call 
this adds an optional failsafe function that will be called in the
timer loop
 2011-12-21 23:31:38 +11:00
Andrew Tridgell f6f808357c removed AperiodicProcess code 
this code was never being used, and was more complex than it was
worth.

Andrew Tridgell c41e7c505b timer: enable interrupts during timer processing 
this prevents us losing serial bytes when we call sensor drivers that
take more than 100usec to read.

We also prevent timer recursion by re-enabling the timer after all
callbacks are complete
 2011-12-16 20:09:38 +11:00
Andrew Tridgell b484411c41 timers: change to 1kHz timer by default 
we were using a 227Hz timer, which is far too slow
 2011-12-16 20:09:25 +11:00
Pat Hickey 49ca774734 AP_PeriodicProcess: AP_TimerProcess can register multiple callbacks. 2011-12-11 15:21:10 -08:00
Pat Hickey d2a0bd35f4 hil-sensors: added stub libraries for InertialSensor and PeriodicProcess 
* Also added dummy ivar to APM_BMP085_hil
 2011-11-25 20:00:18 -08:00
Pat Hickey d288b8870d purple: added PeriodicProcess library 
this library provides a clean API for drivers to request periodic
timer driven calls at whatever rate they need
