DHT22 esp32 #307

Closed Ikusto closed 5 years ago

Ikusto commented 5 years ago

Hello, tell me how to enable DHT22 for esp32. The sensor is exactly working, when checked with a test sketch for esp32, the readings are displayed. In the preferences of the web interface, "Show DHT output" is included, but I see only static 20 ° C and 20%. Perhaps the FW version is not the same, or I’m doing something wrong, but in “ESP3D Settings” I don’t see the DHT22 item.

SDK: v3.2-dev-39-gaaf12390 FW version: 2.0.0.c23 ESP32

I apologize for Google translator.

if DHT is not visible in settings it means it is not enable at compilation, by default it is commented in config.h Uncomment this line here : https://github.com/luc-github/ESP3D/blob/2.0/src/config.h#L77

and use proper pin here : https://github.com/luc-github/ESP3D/blob/2.0/src/config.h#L114

I did right away, but unfortunately that's not the point. Here are the screenshots. image image image

The test firmware for esp32 from "DHT_sensor_library_for_ESPx" works. image

Hi thanks for reporting, issue is not related to DHT detection when you compile the ESP3D the config.h is inside the library as on my side when I enable DHT in config.h the DHT appear in settings image but as you show you do not have it so - DHT is not enabled in code

When you recompiled you modified another config.h not the library one this is my guess

Additionnaly looking at code I have found an ugly bug I never noticed before, I have fixed it but it is not related to your issue

You're right. It worked, not quite as I expected. Thank you for help. The topic can be closed.
