This project is aimed at providing Stata, SPSS, and R code for all DHS Program indicators listed in the Guide to DHS Statistics. The code is published on the DHS Program Github site which contains three repositories: DHS-Indicators-Stata, DHS-Indicators-SPSS, and DHS-Indicators-R. Users can download the code from these repositories or clone the ...

2024年10月31日 · 这个文件定义了一个mq4气体传感器处理的线程，初始化了传感器的硬件抽象层，并设置了线程的优先级、栈大小和时间片。 线程的主要任务是周期性地读取mq4传感器的模拟输出电压，并转换为电压值，同时检查数字输出状态。读取到的数据会被打印到控制台。

2023年8月1日 · 我们可以通过MT4上方的”工具”菜单下的MQ语言编译器进入编译器界面，左侧会看到整个MQL4目录结构。点击智能交易EA的”Experts”文件夹，就可以看到其中的mq4文件，双击文件即可在编译器中进行编辑。但是，编译器中是看不到ex4文件的。
