这是一个STM32 图像处理 RGB转灰度转二值化的DEMO
单片机源程序如下:
- #include <stm32f10x.h>
- #include <stdio.h>
- #include <Nvic_Exit.h>
- #include <delay.h>
- #include <tft.h>
- #include <ov7670.h>
- #include<I2C.h>
- typedef enum {TRUE = 0, FALSE = !TRUE} bool;
- void RCC_Configuration(void);
- void IO_Init(void);
- void CLK_generate(void);
- main()
- {
- RCC_Configuration();;//系统时钟设置
- delay_init(72); //延时初始化
- GPIOA->ODR ^= (1 <<3); //LED1闪烁一次
- LCD_Init();
- IO_Init();
- LCD_Clear(BLUE); //清屏
- POINT_COLOR=YELLOW;
- BACK_COLOR=BLUE;
- LCD_ShowString(20,50,"QF Welcom");
- LCD_ShowString(20,100,"STM32 Camera");
- LCD_ShowString(20,150,"OV7670 Initing......");
- InitI2C0();
- while(1!=Cmos7670_init()); //CMOS初始化
- Exit_Init(GPIOC, GPIO_Pin_4, GPIO_Mode_IPU, EXTI_Trigger_Falling, 2, 5); //VSYNC
- while(1)
- {
- }
- }
