Hi there, I'm trying to use a ds18b20 sensor and temperature reading was working fine so I decided to go all the way and add CRC checking to make the program more robust. When reading the whole memory I see that the sensor's CRC is always a different value even for the same set of bytes. The calcul…

This is the relevant part of the code: Post ALL the code. Your opinion of relevance is unlikely to be relevant. [image] iamagainst: But could a counterfeit sensor give a right temperature and wrong CRC? Of course! If you want genuine sensors, the only way to be sure is buy them from a re…
