Andrew Tridgell bea0a46410 AP_HAL: added servorail_voltage and power_status_flags() API on AnalogIn 2014-02-15 05:00:09 +11:00
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

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.

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
this allows voltage/current/Vcc sensing on FMUv2

Andrew Tridgell 4794d90bbb HAL_PX4: support up to 16 analog channels 2013-08-30 13:01:32 +10:00
Andrew Tridgell d7d87f827e HAL_PX4: support voltage monitoring on multi-connector pin 5 2013-06-05 08:24:20 +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
2013-05-13 15:12:43 +10:00
Andrew Tridgell 9bc48c9894 HAL_PX4: fixed build with new AnalogIn API
pin settle times not actually implemented on PX4 yet
2013-05-03 10:09:02 +10:00
Andrew Tridgell ccd38e58a1 HAL_PX4: fixed the scaling on the analog pins 2013-05-02 21:40:15 +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 e42cf918fd HAL_PX4: added AnalogIn driver
this allows airspeed to work on a PX4
