STC8H8K64U驱动TCS34725颜色识别模块

TCS34725是一款RGB颜色传感器，可以通过I2C接口与STC8H8K64U单片机进行连接，实现颜色识别功能。下面是一个简单的驱动程序示例：

#include <reg52.h>
#include <intrins.h>

#define I2C_SCL P1_5
#define I2C_SDA P1_4

void I2C_start()
{
    I2C_SDA = 1;
    I2C_SCL = 1;
    _nop_();
    _nop_();
    I2C_SDA = 0;
    _nop_();
    _nop_();
    I2C_SCL = 0;
}

void I2C_stop()
{
    I2C_SDA = 0;
    I2C_SCL = 1;
    _nop_();
    _nop_();
    I2C_SDA = 1;
    _nop_();
    _nop_();
}

void I2C_write(unsigned char dat)
{
    unsigned char i;
    for (i = 0; i < 8; i++)
    {
        if (dat & 0x80)
            I2C_SDA = 1;
        else
            I2C_SDA = 0;
        I2C_SCL = 1;
        _nop_();
        _nop_();
        I2C_SCL = 0;
        if (i == 7)
            I2C_SDA = 1;
        dat <<= 1;
    }
}

unsigned char I2C_read()
{
    unsigned char i, dat = 0;
    for (i = 0; i < 8; i++)
    {
        I2C_SCL = 1;
        _nop_();
        _nop_();
        dat <<= 1;
        if (I2C_SDA)
            dat |= 0x01;
        I2C_SCL = 0;
    }
    return dat;
}

void TCS34725_write(unsigned char addr, unsigned char dat)
{
    I2C_start();
    I2C_write(0x29);
    I2C_write(addr);
    I2C_write(dat);
    I2C_stop();
}

unsigned char TCS34725_read(unsigned char addr)
{
    unsigned char dat;
    I2C_start();
    I2C_write(0x29);
    I2C_write(addr);
    I2C_start();
    I2C_write(0x29 | 0x01);
    dat = I2C_read();
    I2C_stop();
    return dat;
}

void TCS34725_init()
{
    TCS34725_write(0x80, 0x03); // Power ON, RGBC enabled
    TCS34725_write(0x81, 0xFF); // Set integration time to 2.4ms
    TCS34725_write(0x8F, 0x00); // Disable interrupts
}

unsigned int TCS34725_read_color()
{
    unsigned int r, g, b;
    TCS34725_write(0x94, 0x1D); // Start a new conversion
    while ((TCS34725_read(0x93) & 0x01) == 0)
        ; // Wait for conversion to complete
    r = TCS34725_read(0x96);
    r |= TCS34725_read(0x97) << 8;
    g = TCS34725_read(0x98);
    g |= TCS34725_read(0x99) << 8;
    b = TCS34725_read(0x9A);
    b |= TCS34725_read(0x9B) << 8;
    return (r << 16) | (g << 8) | b;
}

void main()
{
    unsigned int color;
    TCS34725_init();
    while (1)
    {
        color = TCS34725_read_color();
        // 处理颜色数据，例如判断红色分量是否高于绿色和蓝色分量
    }
}

以上是一个简单的程序示例，具体的应用还需要根据具体的需求进行修改和完善。
