When the sampling rate is about 8 times of the minimum periodic waveform frequency, it is the most suitable one.
After choosing a high sampling rate, there are only a lot of sampling points in the cycle, but the time length of IIC data is unchanged.
If the storage depth is unchanged, if the sampling rate is high, the time length of the collected data will be shorter, and it may not be able to complete a complete data acquisition. This makes decoding impossible.
