Hi everyone, It seems that some obscures problems were found with I2C. Can I make an modest sugestion ? I did my first test with I2C (using Arduino IDE) , I found that SDA and SCL Lines are very sensitive to the squaring of signals. I do'nt know if you are using Internal pullup resistors, but in my ...

Picture of circuit ( ESP32 DEVKIT) : https://www.flickr.com/photos/jgustavoam/39420488295/in/album-72157665409004158/ I did my first test with I2C Interface using Arduino IDE. And it works ! I2C scanner based on code of Nick Gammon http://www.gammon.com.au/forum/?id=10896 Very simple ! The I2C cloc...

Starting my ESP8266 tutorial in 2015 (Portuguese only), there are over 73,000 views so far, mainly in Brazil, but some people from Portugal and countries of Africa. http://labdegaragem.com/forum/topics/conhecendo-o-esp8266 Now , I've started new tutorial of ESP32 (also in portuguese). Detailed with ...

Hi ,
My suggestion is that you study AD7705 datasheet and convert Arduino Libray to ESP32 Library .

Hi ,
I suposed yhat you are using ACS712-30A for measurement of low currents ( 66mV / A) . It´s not recommended !
This sensor don't has good linearity . Other types of ACS712 has not good linearity, too.
ESP32 support only 1,0V at ADC Input. Then you must do a voltage divider.
