I'm running into a problem that is preventing the Weather Station Color with the Wemos board from getting past the "PIFFS opened" state. The serial monitor output shows this progress:
...Connected...Initializing touch screen...
Mounting file system...
Calibration not available
At that point nothing else happens, the screen is lit but blank. Not sure what to do here or how to interpret this information. Reading through the sketch I believe the LCD touch screen is being calibrated? With the original Wemos that came with the kit it could not connect to wifi. However, I did get the Thingpule splash screen with the message that the board was connecting, so the LCD does work, but that was as far as it got. I subsequently bought a second Wemos D1 Mini Pro from Amazon and that board connects just fine but now I get the error message shown above. So there seems to be some quality control or version issues going on with the Wemos boards. I re-checked the versions of all the libraries I installed for this project and they are all the latest. I double-checked the openweathermap API key, that is correct. I'd truly appreciate any help troubleshooting this. Thanks!
