A library for reading dht sensors (temperature and humidity). Since dht sensors are pretty slow, I have used highlevel functions in the lib, there should be plenty of cycles even at 1MHz, but I have only tested it on the CC3200 sofar. Easy example, other functions are available for getting the raw values instead of float. if (dht::readFloatData(2, &temperature, &humidity, true) == 0) { Serial.print("T: "); Serial.print(temperature); Serial.print(" H: "); Serial.println(humidity); } Zip file included, source code lives at https://github.com/MORA99/Stoke -
I decided to build an air humidity alarm so I know when to air (you can also attach a piezo buzzer, which is more recognizable in some situations). I found/use this lib. Chip: MSP430G2452 (this I had left, I think it's overkill for this task) -- Problem solved. Thanks to all who helped. To solve the problem I decided to comment out if (millis() < _lastMillis) { return _lastResult; // return last correct measurement } _lastMillis = millis() + 1; in DHT22_430.cpp because I think the millis() doesn't run below LPM1. I also don't need the millis() because I already wait in interru
