Can not read Vbatt with ardupilot

Posted by Ludovico Antonio on August 2, 2011 at 5:49am

Hey guys!

My ardupilot voltage reading isnt working =(

 

In the telemetry (which is working fine) it reads "battery 3.83V" and I can not understand where is this value coming from. It reads 3.83 even if the proper battery readings pin is not connected and very small changes happens if I plug the battery to it.

Any suggestions?

 

Many tnks!

    Hi, have you set up the battery voltage in the AP_Config.h file?

     

    /***************************************/

    //Battery:

    #define BATTERY_EVENT 0 // (boolean) 0 = don't read battery, 1 = read battery voltage (only if you have it wired up!)

    #define INPUT_VOLTAGE 5200.0 // (Millivolts) voltage your power regulator is feeding your ArduPilot to have an accurate pressure and battery level readings. (you need a multimeter to measure and set this of course)
