These are two snippets of code I had working. The one on the right is written in Russian I believe but this would do the conversion of frequency to RPM and display it on the console window and the one on the right I used to check if the OLED display was working. This was a simple program that would simply print out "Hello World". My next step in completing the code is to try and combine the two code together to try and get it to display the RPM on the OLED display. Below is the attempted combination of the two code however it did not end up working
