Andrew Tridgell 1849db7074 AP_HAL: added board_voltage AnalogIn method 
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 a587b1140a AP_HAL: added voltage_latest() interface 
this will be used for reading the 5V rail
 2013-09-12 13:23:04 +10:00
Andrew Tridgell a5b20b4dfc AP_HAL: removed scaling factor on analog sources 
these are not use anymore, as voltage_average() is used instead
 2013-05-13 15:29:42 +10:00
Andrew Tridgell 589b8cdb58 AP_HAL: added voltage_average_ratiometric() call to AnalogIn 
this is for ratiometric sensors such as the 3DR airspeed sensor and
the Maxbotix analog sonar

Andrew Tridgell 5ac493908c SITL: fixed build with new AnalogIn API 2013-05-03 10:08:39 +10:00
Andrew Tridgell b1c27407a2 AP_HAL: added voltage_average() interface to AnalogIn 
returns voltage in Volts, using averaged reading over samples.

Where possible this should be auto-scaled against a known reference
voltage

Andrew Tridgell abbe37be37 SITL: added emulated airspeed sensor on a pin 2012-12-20 14:52:33 +11:00
Andrew Tridgell 46f7c9e92b SITL: added basic analogin implementation 2012-12-20 14:52:33 +11:00
Andrew Tridgell 98ead51801 SITL: fill in a lot more of the AP_HAL SITL backend 2012-12-20 14:52:30 +11:00
