能利用stm32f4+ov5640去识别黑色(Recognition of Black Using stm32f4+ov5640)

基于ARM的芯片多数为复杂的片上系统,这种复杂系统里的多数硬件模块都是可配置的,需要由软件来设置其需要的工作状态。因此在用户的应用程序之前,需要由专门的一段代码来完成对系统的初始化。(ARM-based chips, most of the complex system on chip, where the majority of this complex system can be configured hardware modules are required by the software to set up the working status of their needs. Therefore, the application before the user needs from the special section of code to complete the initialization of the system.)
