I2C issue with ESP32 and digital potentiometers

[Yolnit]

Hello everyone,

I am using an ESP32WROOM32UE for my PCB and I am currently using GPIO27 and GPIO14 for the digital SDA and SCL signals of my I2C bus. On the I2C bus, I have 2 digital potentiometers AD5245BRJZ5-RL7, here the datasheet https://www.mouser.fr/datasheet/2/609/A ... 601824.pdf and here is the problem.

After a few utilizations, I can't read or write data from the potentiometers anymore. I didn't put any zener diode on digital pins to avoid overvoltage peak but I also noticed that sometimes, I didn't respected the order of powering for the component, as explained in the datasheet.

I'd like to know if this problem may have caused any trouble on the I2C bus from the ESP32. I am asking because I tried to use the I2C on another component that need I2C but it seems, the I2C doesn't work anymore.

Thank by advance.
