## 开发脚本的前提条件是必须掌握python语言
|
|||
|
## 非windows用户,想要打印出信息,用self.printlog(string),并在控制台下运行DSView。但是最终需要注释掉,因为影响性能。
|
|||
|
## 更复杂的协议请查考(0-i2c、0-spi、 0-uart、1-i2c、1-spi、1-uart)
|
|||
|
## 底层模块提供的属性有:
|
|||
|
## 1. samplenum 数据样品位置
|
|||
|
## 2. matched 本次查找调用wait匹配的信息,返回一个uint64类型数值,表示0到63个通道的匹配信息
|
|||
|
## The prerequisite for developing scripts is to master Python language
