STM32F4xx PCROP应用
<p>Proprietary Code Read Out Protection (PCROP) ----- 专有代码读取保护 现在产品开发过程中，二次开发将会越来越多，设计公司开发出自己产品后交给终端客户进行二次功能或补充开发，简称二次开发，设计公司某些程序代码不希望公开给终端客户，但同时又希望部分函 数功能可以给终端客户使用，这时就需要有一种专有代码保护机制供客户使用，STM32F4xx 芯片中

STC15W204及0.96寸IIC的OLED制作个温湿度计
用SI7021、STC15W204及0.96寸IIC的OLED制作个温湿度计。<br />
这个温湿度计是用于最后版办公室多功能桌面工具组合操作显示界面用的http://bbs.mydigit.cn/read.php?tid=2210356，由于SI7021是IIC总线的，如直接由工具组合显示主控控制SI7021，占用资源多，所以把它独立出来，用片STC15W204读SI7021，然后采用模拟红外
