zedboard HDMI ov5640

The Zedboard is a development board that features the Xilinx Zynq-7000 All Programmable System-on-Chip (SoC). The board includes an HDMI interface and a camera interface that can be used to connect an OV5640 camera sensor.

To use the OV5640 camera with the Zedboard, you will need to follow these steps:

1. Connect the OV5640 camera sensor to the Zedboard's camera interface. The camera interface is a 15-pin FPC connector located near the HDMI interface.

2. Configure the Zynq-7000's programmable logic (PL) to interface with the OV5640 camera sensor. This can be done using the Xilinx Vivado Design Suite.

3. Write software to control the OV5640 camera sensor and capture images. This can be done using a programming language such as C or Python.

4. Display the images captured by the OV5640 camera sensor on the Zedboard's HDMI interface. This can be done using a software application that reads the image data and displays it on the HDMI interface.

Overall, integrating the OV5640 camera sensor with the Zedboard's HDMI interface can be a complex task that requires knowledge of both hardware and software development. However, with the right tools and resources, it is possible to create a powerful imaging system that can be used for a variety of applications.

ov5640摄像头显示例程

以下是ov5640摄像头显示的简单例程：

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <fcntl.h>
#include <sys/ioctl.h>
#include <linux/i2c-dev.h>

#define OV5640_ADDR 0x78

int fd_i2c;

int ov5640_write_reg(unsigned short reg, unsigned char value)
{
    unsigned char buf[2];
    buf[0] = reg >> 8;
    buf[1] = reg & 0xff;

    if (write(fd_i2c, buf, 2) != 2) {
        return -1;
    }

    buf[0] = value;

    if (write(fd_i2c, buf, 1) != 1) {
        return -1;
    }

    return 0;
}

int ov5640_init()
{
    ov5640_write_reg(0x3008, 0x80);
    usleep(10000);

    ov5640_write_reg(0x3103, 0x93);

    ov5640_write_reg(0x3008, 0x20);
    usleep(10000);

    ov5640_write_reg(0x3008, 0xa0);
    usleep(10000);

    ov5640_write_reg(0x3103, 0x03);
    usleep(10000);

    ov5640_write_reg(0x3008, 0x00);
    usleep(10000);

    ov5640_write_reg(0x3103, 0x93);
    usleep(10000);

    return 0;
}

int ov5640_start()
{
    ov5640_write_reg(0x3103, 0x03);
    usleep(10000);

    ov5640_write_reg(0x3008, 0x02);
    usleep(10000);

    ov5640_write_reg(0x3008, 0xa2);
    usleep(10000);

    return 0;
}

int main()
{
    fd_i2c = open("/dev/i2c-0", O_RDWR);

    if (fd_i2c < 0) {
        printf("Cannot open i2c device\n");
        return -1;
    }

    if (ioctl(fd_i2c, I2C_SLAVE, OV5640_ADDR) < 0) {
        printf("Cannot set i2c slave address\n");
        return -1;
    }

    if (ov5640_init() < 0) {
        printf("Cannot init ov5640 camera\n");
        return -1;
    }

    if (ov5640_start() < 0) {
        printf("Cannot start ov5640 camera\n");
        return -1;
    }

    printf("ov5640 camera started\n");

    // Add your code to display the image captured by the ov5640 camera here

    return 0;
}

这个例程通过 i2c 总线与 ov5640 摄像头通信，初始化 ov5640 摄像头并启动它。在 ov5640 摄像头启动后，你需要自己编写代码来显示 ov5640 摄像头捕获的图像。
