// --------- 6 - Voltages & Current sensor settings ---------

// ***** 6.1 - Voltage Reference to measure voltages and current *****
//#define USE_INTERNAL_REFERENCE  // uncomment this line if you use 1.1 volt internal reference instead of Vcc (voltage divider mst be used to reduce voltages to 1.1 volt max)
//#define USE_EXTERNAL_REFERENCE  // uncomment this line if you use an external reference instead of Vcc
//#define REFERENCE_VOLTAGE 4970    // set value in milliVolt; if commented, oXs will use or 1100 (if internal ref is used) or 5000 (if internal ref is not used)

// ***** 6.2 - Voltage parameters *****
#define PIN_VOLTAGE         0  , 1  , 8   , 8    , 8   , 8               //  Fill 6 values; set to 0 up to 7 for analog pins A0 up to A7 ; set the value to 8 for the voltage(s) not to be measured.
#define RESISTOR_TO_GROUND  0 , 0    , 10  , 10 , 0  , 18               // set value to 0 when no divider is used for a voltage; can contains decimals
#define RESISTOR_TO_VOLTAGE 0 , 0 , 22 , 27  , 0 , 47              // set value to 0 when no divider is used for a voltage; can contains decimals
#define OFFSET_VOLTAGE      0   , 0     , 0    , 0    , 0   , 0                // optionnal, can be negative, must be integer, in principe in mv

// ***** 6.3 - Max number of Lipo cells to measure (and transmit to Tx) *****      Is defined only in oXs_config_basic.h file

// ***** 6.4 - Convert voltage to temperature (° Celcius) *****    
#define FIRST_NTC_ON_VOLT_NR 1   // uncomment this line when thermistor are used; specify index of first voltage being used for conversion to temperature (e.g. 5 means VOLT_5)
#define LAST_NTC_ON_VOLT_NR 2    // specify index of last voltage being used for conversion to temperature (e.g. 6 means VOLT_6)
#define SERIE_RESISTOR 9985      // resistance connected to Arduino Vcc (in Ohm)
#define STEINHART_A 7.00111E-4   // these parameters are specific to the NTC being used.
#define STEINHART_B 2.1644E-4
#define STEINHART_C 1.0619E-07

//#define TERMISTOR_NOMINAL 100000 // nominal resistor of NTC (in Ohm)                    Those 3 parameters are not used anymore (replaced by STEINHART8A B and C
//#define TEMPERATURE_NOMINAL 25 // nominal temperature of NTC (in degree Celcius)
//#define B_COEFFICIENT 3950 // B coefficient of NTC

// --------- 1 - Telemetry protocol ---------
