Hello, I'm trying to build a temperature sensor using the Attiny1614 using a 0.96 oled and a DS18B20 temperature sensor. I mange to get the oled working by using the Tiny4Koled. here. Also I found the DS18B20 temperature here. For some unknown reason beyond my programming skills I can not get the Temperarure sensor working. The attiny1614 does have spi and i2c on it. But not serial. well it does have serial but i would need to hook up a FTDI to it for it to work. The Attiny1614 programs by UPDI. I really need help to figure out what is wrong. Can someone help me please? My sketch is below.
Edit: I get no errors in compiling. I just get no temperature.
