I saw and try this tutorial for scanning i2c, but nothing is scanned when scanning!
to i2c.read() is printing 0
to i2c.end() is printing 2
I put pull-up resistors to VCC of both pins!
So you are saying that is working normally? what exactly? you ESP board? your max6675? with what? Please help me understand a bit more from your setup and tests.
Your whole setup is working ok with max6675 but max6675 is not detected by I2C scanner?
That sounds odd.
What value do you have for your SDA/SCL pull-up resistors?
