LilyGo Hi-Grow DS18B20

I get no valid data from DS18B20 connected to the OneWire bus (IO21). According to the schematic, there should be a pullup resistor.
I used the ds18b20.h from https://github.com/Xinyuan-LilyGO/LilyGo-HiGrow/tree/master/src.

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