Excitation Voltage Output

[Anupriya12-07]

How to define macros for excitation voltage output. I am using AD5933 for impedance measurement .But i did not known how to set the excitation voltage value .
arduino-ad5933-master.zip
This is code i upload.Please tell me the correct place to include excitation voltage macro and its functions.

Check in the header file. You willl find the "setRange" function, allowing you to define the range based on one of the macro also defined in the header file (ex: "CTRL_OUTPUT_RANGE_1"). Check the datasheet corresponding to the AD5933 to know which one to use.
You will want to call this function in the setup.

Sir, I am using setRange(CTRL_OUTPUT_RANGE_1) in the setup function but it is error . How to use the function Please tell me sir

Could you send your code, with the error please?

[Anupriya12-07]

Arduino: 1.8.16 (Windows 7), Board: "Arduino Uno" I have attached the code in the word document This is error message AD5933_Arduino_github:37:45: error: cannot call member function 'bool AD5933::setRange(byte)' without object AD5933::setRange(CTRL_OUTPUT_RANGE_2))) ^ exit status 1 cannot call member function 'bool AD5933::setRange(byte)' without object

Ah yes I see. Go in the header file and the "static" keyword before the function name. You should have this: "static bool setRange(byte);"
`/**

• AD5933 Library class

• Contains mainly functions for interfacing with the AD5933.
  */
  class AD5933 {
  public:
  // Reset the board
  static bool reset(void);

  // Temperature measuring
  static bool enableTemperature(byte);
  static double getTemperature(void);
  
  // Clock
  static bool setClockSource(byte);
  static bool setInternalClock(bool);
  static bool setSettlingCycles(int);
  
  // Frequency sweep configuration
  static bool setStartFrequency(unsigned long);
  static bool setIncrementFrequency(unsigned long);
  static bool setNumberIncrements(unsigned int);
  
  // Gain configuration
  static bool setPGAGain(byte);
  
  // Excitation range configuration
  static bool setRange(byte);
  
  // Read registers
  static byte readRegister(byte);
  static byte readStatusRegister(void);
  static int readControlRegister(void);
  
  // Impedance data
  static bool getComplexData(int*, int*);
  
  // Set control mode register (CTRL_REG1)
  static bool setControlMode(byte);
  
  // Power mode
  static bool setPowerMode(byte);
  
  // Perform frequency sweeps
  static bool frequencySweep(int real[], int imag[], int);
  static bool calibrate(double gain[], int phase[], int ref, int n);
  static bool calibrate(double gain[], int phase[], int real[],
                        int imag[], int ref, int n);
  

  private:
  // Private data
  static const unsigned long clockSpeed = 16776000;

  // Sending/Receiving byte method, for easy re-use
  static int getByte(byte, byte*);
  static bool sendByte(byte, byte);
  

};`

Can you post the code here, on github? Because you might be sending it by email, which only takes the text. I would like to have some precisions as well on your setup.
