Product Number: ADE7753
Software Version: IDE 2.2.1
I have a problem with a program to connect ADE7753 and Arduino Uno. I made a pcb (photo). I'm using this library: https://github.com/chandrawi/ADE7753/tree/main. When I upload the example code for energy meter it's happens something like this on the photo. I have connected only + 5V to the pcb, without connecting 230 V and current transformer. What am I doing bad? Can somebody help with the code? How I have to calibrate ADE7753?
The code is:
#include "ADE7753.h"
ADE7753 meter; // Default constructor
// SPIClass Hspi(HSPI);
// ADE7753 meter(Hspi, 15, 4000000); // Constructor for non-default SPI bus and frequency
// Clock frequency and calibration coeficient
const uint32_t CLK_FREQ = 3579545;
const double AENERGY_COEF = 1.0;
const double VAENERGY_COEF = 1.0;
const double IRMS_COEF = 1.0;
const double VRMS_COEF = 1.0;
void setup() {
Serial.begin(115200);
meter.begin();
/*
Set channel 1 (current) and channel 2 (voltage) gain
ADE7753_GAIN_1
ADE7753_GAIN_2
ADE7753_GAIN_4
ADE7753_GAIN_8
ADE7753_GAIN_16
*/
meter.setCh1Gain(ADE7753_GAIN_8);
meter.setCh2Gain(ADE7753_GAIN_2);
/*
Set channel 1 (current) full scale
ADE7753_FS_0_5V => 0.5 V
ADE7753_FS_0_25V => 0.25 V
ADE7753_FS_0_125V => 0.125 V
*/
meter.setCh1FullScale(ADE7753_FS_0_5V);
Serial.println("\nAEnergy\tVAEnergy\tFrequency\tRMS Current\tRMS Voltage");
}
void loop() {
double AEnergy = AENERGY_COEF * meter.readAEnergy();
double VAEnergy = VAENERGY_COEF * meter.readVAEnergy();
double Frequency = (double) (CLK_FREQ / 8.0) / meter.readPeriod();
double IRMS = IRMS_COEF * meter.readCurrentRMS();
double VRMS = VRMS_COEF * meter.readVoltageRMS();
// Show active and apparent energy, frequency, and RMS current and voltage
Serial.print(AEnergy);
Serial.print("\t");
Serial.print(VAEnergy);
Serial.print("\t");
Serial.print(Frequency);
Serial.print("\t");
Serial.print(IRMS);
Serial.print("\t");
Serial.println(VRMS);
delay(1000);
}
