@caz that's great , if you have any other questions in use, please feel free to contact us.

You can use this program directly. It will generate a web page and then display the data of DS18B20.

@vince925 Excuse me, What are the SDA pin and SCL pin of the I2C protocol you use? Whether the hardware connection and I2C scan pins are consistent

@papbo You are using the MAC operating system. But dev/cu.usbmodem cannot burn programs. So please enable a setting to use the serial port burning function normally.

Then a new serial port /dev/tty.wchusbserialXXXX will be generated, you can select it and burn the program

@joter Sorry. T3 is not using Espressif driver, but using ch9102 driver chip. I now send you the driver link of win10
