以下是TCS3473颜色传感器识别红、蓝、绿的51单片机程序:
```c
#include <reg51.h>
#include <intrins.h>
#define TCS3473_ADDR 0x29
#define COMMAND_BIT 0x80
#define AUTO_INCREMENT_BIT 0x20

#define ID_REG_ADDR 0x12
#define DATA_REG_ADDR 0x16
sbit SDA = P1^0;
sbit SCL = P1^1;
void TCS3473_WriteByte(unsigned char addr, unsigned char value);
unsigned char TCS3473_ReadByte(unsigned char addr);
unsigned int TCS3473_ReadData(void);
void TCS3473_Init(void);
void Delay1ms(void);
void Delay10ms(void);
void main()
{
unsigned int r, g, b;
TCS3473_Init();
while(1)
{
r = TCS3473_ReadData();
Delay10ms();
g = TCS3473_ReadData();
Delay10ms();
b = TCS3473_ReadData();
Delay10ms();
if(r > g && r > b)
P2 = 0x01; // 红色
else if(g > r && g > b)
P2 = 0x02; // 绿色
else if(b > r && b > g)
P2 = 0x04; // 蓝色
else
P2 = 0x00; // 其他颜色
}
}
void TCS3473_WriteByte(unsigned char addr, unsigned char value)
{
unsigned char i;

SCL = 0;
addr <<= 1;
}
for(i = 0; i < 8; i++)
{
if(value & 0x80)

else
SDA = 0;

}

}
unsigned char TCS3473_ReadByte(unsigned char addr)
{
unsigned char i, value = 0;

SDA = 0;
SCL = 0;
for(i = 0; i < 8; i++)
{
if(addr & 0x80)
SDA = 1;
else
SDA = 0;
SCL = 1;
SCL = 0;
addr <<= 1;
}
SDA = 1;
SCL = 1;
SCL = 0;
for(i = 0; i < 8; i++)
{
value <<= 1;
if(SDA)
value |= 0x01;
SCL = 1;
SCL = 0;
}
SDA = 1;
SCL = 1;
SCL = 0;
return value;
}
unsigned int TCS3473_ReadData(void)
{
unsigned char high, low;
unsigned int value;
high = TCS3473_ReadByte(DATA_REG_ADDR + 1);
low = TCS3473_ReadByte(DATA_REG_ADDR);
value = high;
value <<= 8;
value |= low;
return value;
}
void TCS3473_Init(void)
{
TCS3473_WriteByte(ENABLE_REG_ADDR, 0x03); //开始测量RGB颜色
TCS3473_WriteByte(RGBC_TIMING_REG_ADDR, 0x00); //RGBC时间设置为2.4ms
TCS3473_WriteByte(CONTROL_REG_ADDR, 0x01); //增益设置为1倍
}
void Delay1ms(void)
{
unsigned int i, j;
for(i = 0; i < 10; i++)
for(j = 0; j < 120; j++);
}
void Delay10ms(void)
{
unsigned int i;
for(i = 0; i < 10; i++)
Delay1ms();
}
```
该程序通过51单片机控制TCS3473颜色传感器进行测量,并根据测量结果判断颜色是否为红、绿、蓝。程序中使用了延时函数,需要根据实际情况进行调整。
