Getting 65535 values for Current and voltage

[abraralishah12]

I am currently working on a PROJECT and ordered your PCB without esp32 full kit. And I am getting 65535 values for both current and voltage

[CircuitSetup]

The first thing to check is that everything is wired correctly.
Do the meter and esp32 share a ground?
Are the SPI wires connected on the pins specified in the program?
Also, how is everything being powered?

[abraralishah12]

Yes they share a ground. SPI wires are connected as specified in the program. Currently, I am powering them from USB port. I haven't connected the 9V transformer yet. I used a 9V transformer earlier but it had damaged my IC and ESp32. So right now I am only checking Current value.

@CircuitSetup kindly assist me on above issue.

Wait, what exactly did the 9V AC transformer burn out? It should only be plugged directly into the meter.

When you power the ESP32 via micro USB, is the meter showing a green light? Do any of the other lights blink when a current transformer is hooked up and around a wire with current going through it?

[abraralishah12]

When I power esp32 with USB, green led blinks. When I ordered the PCB resistor array was short so other LEDs did not blink because of the open path in the PCB circuit.

@CircuitSetup kindly have a look at it.

When I power esp32 with USB, green led blinks. When I ordered the PCB resistor array was short so other LEDs did not blink because of the open path in the PCB circuit.

Is there a solid green light on the meter?

Specifically, what program are you running on the ESP32?

[abraralishah12]

@CircuitSetup yes, green led, and it blinks when I power it with USB.
Below is the code:
`

#include <ATM90E32.h>

const int CS_pin = 5;
/*
18 - CLK
19 - MISO
23 - MOSI
*/

unsigned short VoltageGain = 37106;
unsigned short CurrentGainCT1 = 25498;
unsigned short CurrentGainCT2 = 25498;
unsigned short LineFreq = 389;
unsigned short PGAGain = 21;

ATM90E32 eic{}; //initialize the IC class

void setup() {
/* Initialize the serial port to host */
Serial.begin(115200);

while (!Serial) {
; // wait for serial port to connect. Needed for native USB
}

/*
Wire.begin();

display.begin(SSD1306_SWITCHCAPVCC);

// Clear the buffer.
display.clearDisplay();
display.setCursor(0, 0);

display.setTextSize(1.5);
display.setTextColor(WHITE);
*/

/*Initialise the ATM90E32 + SPI port */
Serial.println("Start ATM90E32");
eic.begin(CS_pin, LineFreq, PGAGain, VoltageGain, CurrentGainCT1, 0, CurrentGainCT2);
delay(1000);
}

void loop() {

/*Repeatedly fetch some values from the ATM90E32 */
float voltageA, voltageC, totalVoltage, currentA, currentC, totalCurrent, realPower, powerFactor, temp, freq;

voltageA = eic.GetLineVoltageA();
// Voltage B is not used
voltageC = eic.GetLineVoltageC();
totalVoltage = voltageA + voltageC ;
currentA = eic.GetLineCurrentA();
// Current B is not used
currentC = eic.GetLineCurrentC();
totalCurrent = currentA + currentC;
realPower = eic.GetTotalActivePower();
powerFactor = eic.GetTotalPowerFactor();
temp = eic.GetTemperature();
freq = eic.GetFrequency();

Serial.println("VA:" + String(voltageA) + "V");
Serial.println("VC:" + String(voltageC) + "V");
Serial.println("IA:" + String(currentA) + "A");
Serial.println("IC:" + String(currentC) + "A");

delay(1000);
delay(14000);

/*
//Clear display to prevent burn in
display.clearDisplay();
display.display();
*/
}

@CircuitSetup have a look at the code please
