More precise temperature

[RuslanasMobOn]

Hi, is there a possibility for quick fix to read more precise temperature from DS18B20? For now i'm getting just integer. It would be great to get double value.

Yep, can be done. Probably the easiest way is to return the raw value from the DS18B20 as two bytes then do the temperature conversion in the I2C master.

I'm not that much familiar with c/c++ and converting raw data to data types (even more i don't know how to debug ATTiny with Platformio) . It would be great if you give me more clearer hints

what are you trying to achieve? what can you tell me about your project?

I have raspberry pi with android things, i need to get temperature from my waterproof ds18b20, so i read your article, bought ATTiny85 and now i’m getting temperature via ATTiny as slave. But temperature is two digit integer, but i want to get float with more precise value. I’m not familiar with c/c++ , i just use your code and diagrams. So i will be greatful if you help me to get that float value from ds18b20
