B4R Question Error accessing B4R public variables via embedded C code (INA219)

[Cesar_Morisco]

Could anyone tell me how to correctly access these B4R public variables within the embedded C code?
I would greatly appreciate any help!

Sub Process_Globals
    Public Serial1 As Serial
    Public ShuntVoltage As Float
    Public Voltage As Float
    Public Corrente As Float
    Public Pontencia As Float
    Public LoadVoltage As Float
End Sub

Private Sub AppStart
    Serial1.Initialize(115200)
    Log("AppStart")
    RunNative("InitINA", Null)
    StartReading
    
End Sub

Sub StartReading
    AddLooper("LoopINA")
End Sub

Sub LoopINA
    RunNative("ReadINA", Null)
    Log("Tensão: ", Voltage, " V | Corrente: ", Corrente, " mA | Potência: ", Pontencia, " mW")
    Delay(1000)
End Sub

#If C
#include <Wire.h>
#include <Adafruit_INA219.h>

Adafruit_INA219 ina219;

void InitINA(B4R::Object* o) {
  ina219.begin();
}

void ReadINA(B4R::Object* o) {
  float shunt = ina219.getShuntVoltage_mV();
  float bus = ina219.getBusVoltage_V();
  float current = ina219.getCurrent_mA();
  float power = ina219.getPower_mW();
  float load = bus + (shunt / 1000);

  // Atribuindo aos campos públicos declarados no B4R
  b4r_main::_ShuntVoltage = shunt;
  b4r_main::_Voltage = bus;
  b4r_main::_Corrente = current;
  b4r_main::_Pontencia = power;
  b4r_main::_LoadVoltage = load;
}

#End If

This should give you a push in the right direction:

How to use global arrays from inline C

This code will get the Mac-addres from a Wemos D1 Mini. I would like to use the MacArray directly from C using b4r_main::_macarray = MAC_array; But gets this error 'cannot convert 'uint8_t [6] {aka unsigned char [6]}' to 'B4R::Array*' in assignment' sub Process_Globals Dim...

if you have a look at B4Rmain.h in Objects directory, all B4R variables are converted to lowercase :

class b4r_main {
public:

static void initializeProcessGlobals();
static void _appstart();
static void _loopina();
static void _process_globals();
static B4R::Serial* _serial1;
static Double _shuntvoltage;
static Double _voltage;
static Double _corrente;
static Double _pontencia;
static Double _loadvoltage;
