About I²c Summary

I²c is a serial communication protocol that has SDA and SCL high-speed transmissions. With high-level acquisition data, only low level changes the characteristics of the data on the SDA

Briefly describe the timing and working principle of i²c:

1. Start signal and termination signal

Note: Start: During SCL High: SDA pull low as Start signal

Termination: During SCL High: SDA pulls high as termination signal

2. Read the data operation:

Data transfer remember:

1.SCL and SDA correspond well. Do not make the SDA operation clock inconsistent with the SCL operation clock (if the SCL itself makes a clock) it is recommended to step-by-step

2. High level acquisition when reading data

3. Write Data:
