Hi i am working on a school project where I'm supposed to output temperature values on an Oled display.

i have managed to do it with Arduino Code so i know that the sensor and display works, but the code has to be written in Atmel studio in pure embedded C for the project.

I'm not sure what I'm doing wrong and what I'm am doing right.
I'm struggling with C code and the I2C protocol.

i have done a lot of research on the subject but evertime i seem to only find arduino tutorials, or theory related posts.

I'm totally new to programming.

anyway this is the code i have come up with so far.

the txt i have written for the display is displayed. everthing works as it should except for the temperatur values:
