Hey everyone, Im looking to add two pull up resistors to a couple i2c devices im using in my project (displaying sensor values to a screen). I understand the application of the pull up resistor, and ive found resources such as how to calculate, how/why to choose higher or lower values within the range, but im still a little lost as far as what im looking at.

The sensor Im using is 3.3v, and the screen is 5v. Everything ive found as far as calculating goes, depends entirely on power and frequency. Im not sure how to determine the frequencies of what Im using (or if i even need to). Ive found a range of suggested values from 4.7 to 10k, so im not sure if there may be more generally used values for certain things or if i could just figure out how to calculate it myself based on what Ive found. Thanks!

Quick edit: sorry, now I see how silly a question it is asking how to know the frequency, which I should have an oscilloscope for, but unfortunately dont.
