I am learning about the I2C protocol right now. A while ago, I watched a video where the dude said that the SCL and SDA lines going from the Master to the Slave need to have some sort of "Termination resistors".
I cant find the video and need some advice on what these Termination resistors are and if I really need them for every I2C project I run.
- I had success communicating between a UNO and a NANO using the I2C protocol without using the termination resistors. Did I just get lucky? The slave did what it was supposed to do as intended.
- Is the general resistor setup in the pic below good enough to satisfy the I2C termination resistor requirment?
- What value resistors need to be used , if they are needed?
The pic of my intended setup with the Termination resistors is below.
Thank you all for your replies!
BTW, a few weeks ago, I said in one of my previous posts that I will give a small donation to a kids hospital for all the replies that you guys gave. Here is the receipt for that. Thanks again.
