CONFIGURATION

1.1 BATTERY_EVENT ON/OFF

//            *EXPLAINED* 
//                  The voltage sensors are used to accurately monitor your battery 
//                  status during flights.
//
//            *INSTRUCTIONS*
//                  Once you have your hardware setup like in the link above you need to
//                   tell the APM about your setup. 
//                  In your Config.h file you need to Enable your voltage monitoring, to do
//                  this you need to change the statement from 
//                  BATTERY_EVENT "DISABLED" to "ENABLED"
//
//            *AVAILABLE OPTIONS*
//                 BATTERY_EVENT DISABLED
//                 BATTERY_EVENT ENABLED
//
//       *****************
//         *SELECTED OPTION*
     #define BATTERY_EVENT ENABLED
 //       *****************

1.2 BATTERY_SELECTION

 //                    *EXPLAINED*
//                                Because everyone uses different batteries you need to tell the APM what sort of batteries 
//                                you use, unfortunately there are too many types of batteries and we cannot #define all of
//                                them so we only have a selection between most common used ones.
//
//                      *INSTURUCTIONS*
//                            The most commonly used batteries is a 3cell(3S) or a 4cell(4S) to find out what you have look
//                             On the label or spec sheet of your battery you will see a descriptions that looks something
//                             like this ”20-30C DISCHARGE 5000mah 4 cell 14.8V” that means that you have a 4 cell(4S) 
//                             battery and you need to tell the APM that. Here is how change the statement form
//                            BATTERY_TYPE    0  (default/3S) to BATTERY_TYPE  1  (4S)
//
//      **************
//    *SELECTED OPTION*
     #define BATTERY_TYPE  1
//    ***************

1.3 LOW_VOLTAGE_SETTING

//                        *EXPLAINED*
//                             Exactely as the title suggests ,pick a voltage that 
//                             you consider as a low voltage.
//                        
//                        *INSTRUCTIONS*
//                             Change statement from #define LOW_VOLTAGE 11.4
//                             to any voltage you consider as low for your battery type.
//
//    *****************
//    *SELECTED OPTION*
     #define LOW_VOLTAGE  11.4                         
//    *****************
//

1.4 INPUT_VOLTAGE

{{{
EXPLAINED In order to insure more accurate voltage readings you // can measure the Voltage on the 5V rail on your APM oilpan // and #define it here. // // INSTRUCTIONS // NOTE:you need a multimeter for this. // Take the multimeter and measure the voltage // with the negative probe on the bottom row of the servo // connectors on APM board and with the positive probe on // the 5V rail on oilpan and insert the reading here. // NOTE:if you have no multimeter insert 5V (defualt) // ******************* // SELECTED OPTION #define INPUT_VOLTAGE 5.0 // ******************* }}}

1.5 VOLT_DIV_RATIO

                        (under constuction)
                       //#define VOLT_DIV_RATIO      3.0
