The baud rate for the interface is 31.25 Kbaud with 1 start bit, 8 data bits, and 1 stop bit, giving a period of 320 microseconds per serialized byte.
接口的波特率为31.25 k波特，其中包括1个起始位，8个数据位以及1个停止位，每个串行比特周期为320微妙。
The maximum peak-to-peak value of the timing variations in synchronous data expressed as a percentage of the ideal bit period.
在以理想的位周期的百分数表示的同步数据里，用以表示两个峰值间的最大定时变化值。
In the example script provided, the sampling rate is every two seconds, which provides rapid feedback, but generates quite a bit of sample data in a short period of time.
在本文提供的示例脚本中，抽样频率是每2秒抽样一次，这样可以提供快速的反馈，但是在短时间内会产生较多的样本数据。
