calplug / ade7953-wattmeter Goto Github PK

Hello!
I'm using your library to connect an ade7953 to an eps32.

I got this strange reading and I cannot figure out if I'm facing a communication problem

I'm using pin 13 for CS on the chip. FFFFFFFF is -1 on AP_NOLOAD registry. this indicate some problems ? I can't figure out reading datasheet as this value should be 1 or 0

APNOLOAD (hex): FFFFFFFF
Vrms (V): -1.00
IrmsA (mA): -0.00
Apparent Power A (mW): 0.67
Active Power A (mW): 0.67
Rective Power A (mW): -0.67
Power Factor A (x100): 0.00
Active Energy A (hex): -1

Are the board and library compatible with 230 V - 50 Hz?

This code for 60Hz....
You are count all channels 1 sec...

On line 264:

float ADE7953::getIrmsA(){  
	unsigned long value=0;  
	value=spiAlgorithm32_read((functionBitVal(IRMSA_32,1)),(functionBitVal(IRMSA_32,0))); 
	float decimal = decimalize(value, 1327, 0);
return decimal;

Why 1327?

float ADE7953::getVrms(){  
	unsigned long value=0;  
	value=spiAlgorithm32_read((functionBitVal(VRMS_32,1)),(functionBitVal(VRMS_32,0)));
	float decimal = decimalize(value, 19090, 0);
return decimal;
} 

Why 19090?
Are these values were obtained by fitting?
Then why the values differ in dozens of times?
Thanks

can you please help me related to ade7953 interface with esp32 output is as per image 9 on datadocument.
