Hello Jose,
I'm in need of RMS voltage of my input AC supply (230Vac, 50Hz). In my software, I can read my ADC for only 250ms once and adjust a gain parameter accordingly. I can do only very limited calculations on my ADC result.
To achieve this, I thought of using detecting peak voltage and calculating the RMS from that value.
Regarding the speed of my RMS measurement, response in a second is also OK.
Warm Regards,
Senthil
