Guru Meditation Error: Core 0 panic'ed (IntegerDivideByZero). Exception was unhandled. #45

Hi, I am doing a final year project which is a weather station Web with DHT22 sensor for temperature and humidity and pressure with BMP180 sensor all on the Huzzah ESP32 I need help because when a client connects to the server the monitor shows this error and the ESP32 restarts:

Rebooting...

If you could help me because it is very urgent please.

hi your code isnt using this driver at all. if you need project help - post in adafruit forums or some other project support forum.
