Hi there,
I'm getting the following error message when trying to get a DPS310 (bought from SEEED studio) pressure sensor to work with an Arduino Wifi Rev2. I'm using a code example that came with the library (code included below). It won't verify the code. Its part of a weather station project, so will later be joined by humidity/light sensors etc and connected to thingspeak. I really only need the code to produce a single pressure value to add to a thingspeak field, but first I need to get the example code working!
Any help would be greatly appreciated.
