I2C introduction: The protocol 

I agree

Yes thats a mistake in diagram.

Yes, it's a mistake

As others have pointed out, the diagram is incorrect, but the audio is correct. This is a really nice tutorial but I would like to see the repeated start condition covered.

You are spot-on. This video is misleading and low-effort… not what I expected of TI.

SCLK: it is not gated, if sclk becomes high then it is considered as transfer of bits and at that time we are not interested to send data so we can keep the sclk low indicating that there is no data transfer at that moment. SDA: we can keep any value for sda during negative edge of sclk line, the device will sample only during positive clock duration (it has to be stable)

Gating SCL after an Address Frame ACK allows devices to synchronize and complete tasks before proceeding to the next operation for the seek of reliability. As for SDA, it remains stable (high or low) when SCL transitions from low to high to prevent unintended data transitions and maintain synchronization.

For writing drivers too.

I think it's meant for anyone who plans on using I2C in their devices. For example, the sensors I am using in my device communicate using I2C, so I'm just watching this to understand the basics before I watch more complex videos to learn how to pull data from my sensors. The part about the transistors is likely to explain how the lines are pulled to low voltage because many people like to learn about the underlying mechanics so that they know where to look if there's something wrong with their device.

Setting the speed to 2x helps a bit

I actually fell asleep within 2 minutes. Looks like I wasn't the only one lol

Silence, furry. Did you not read the intro?
