No, I wrote:as you said in case of delta connection
NEUTRAL_value = (R + Y + B) / 3
this r,y,b is converted value from ADC_value?? or Adc value need to take.
In software you never have analog values, thus, it's clear that they are ADC values.In software: NEUTRAL_value = (R + Y + P) / 3
I recommend to do heavy low pass filtering on NEUTRAL_value.
Use the math above.IN delta connection there will be no neutral connection?? How can create it? or what will be Rphase value here
What circuit?you have any recommend circuit to make it work.
--> use two resitors. You may add a buffer, but no need to.NEUTRAL = PIC_ADC_VREF / 2
See post#5.In software , when delta connected how calculation i need to do??
It can't know. And it doesn't need to.how MCU will know weather star connection or delta connection??
Friendly reminder : If you are making your own neutral point (Y connection) better you connect your neutral to earth with a dumping impedance. In my region Y neutral - earth difference may vary 2-5V.
Nobody wrote about wikipedia... so what do you refer to?Since I have no access to wikipedia I can't find the source.
in case of 3 phase 3 wire we dont have neutral reference
