Hi @Rubens_Zambelli,
You can check using the logic analyzer on the SDA and SCL pins. Test it out specific APIs whether writing to the slave device is working or not.
Also, please do check common issues that users faced for the library. Amb82 iic wire problem - #13 by ren_yucheng. You will need to add a delay of 1ms after calling Wire.requestfrom() API.
Thank you.
