Power & power factor reading issue while using ACS712 & ZMPT101B Module

Thanks for sharing your knowledge, i never use Atmel chips, so i dont know about it.
Now i know why in the EmonlIb STM32 Branch have the example for one ADC
Some Readme quote:

Firmware examples included in this repository:

For now, i’am happy with the result STM32+ACS712+ZMPT101B and EmonLib ,
and perhaps i will try EmonlibCM too, i just
read in here EmonLibCM - Version 2 (Support) - #84 by Robert.Wall
I read in there, EmonLibCM have a Frequency Meter, so i will try it.

JFI, i make a DC Meter using ESP8266, then I just switch to STM32 because it have 12bit and more channel.
Btw, because ESP8266 only have 1 channel ADC, so i use 2 pc817 to siwtch the reading from Acs712 to read current and voltage divider to read voltage.
