Description

Color Sensor Principle

The TCS230 is available in an 8-pin SOIC surface mount package with 64 photodiodes integrated on a single chip. These diodes are divided into four types. Sixteen of these photodiodes have a red filter; 16 photodiodes have a green filter; 16 photodiodes have a blue filter; and the remaining 16 do not have any filter and can transmit the full light information. These photodiodes are cross-arrayed within the chip, which can minimize the unevenness of the incident light radiation and thus increase the degree of color recognition; on the other hand, the 16 photodiodes of the same color are connected in parallel and evenly distributed in the diode array, which eliminates the positional error of the color. During operation, the desired filter is dynamically selected via two programmable pins. The sensor's typical output frequency range is from 2 Hz to 500 kHz, and the user can also select, via two programmable pins, an output scaling factor of 20% or 2%, or a power shutdown mode. The output scaling factor allows the sensor's output to be adapted to different measurement ranges, increasing its adaptability. For example, when using a low-speed frequency counter, a small calibration value can be selected to match the TCS230's output frequency to the counter.

The simple test program is as follows:

#include<reg52.h

#define uchar unsigned char

#define uint unsigned int

sbit S0=P1^0; //S0,S1 is to set the duty cycle of the output.

sbit S1=P1^1.

sbit S2=P1^3; //S2,S3 is to set the mode of light consideration

sbit S3=P1^4; sbit OE=P1^4; //S2,S3 is to set the mode of light consideration.

sbit OE=P1^2; //Enable

void RS232_init()

{

  TMOD=0X20; //Timer1 working in mode 1

  SCON=0x50.

  PCON=0X80; //

  TH1=TL1=0XFF;//22.1184M crystal, baud rate set to 115200

  TR1=1.

  TR1=1; TI=0.

  RI=0.

}

void send_char(uchar a) // send data

{

    SBUF=a;

    while(TI==0);

    TI=0;

}

uchar get_char() //receive data

{

    while(RI==0);

    RI=0;

Return SBUF;

}

uint color_display(uchar m)

uint color_display(uchar m)

       uint time,a.

       a=m.

       TMOD=0x61; //counter 1, timer 0 works in 16-bit mode

       TH0=TL0=0; //count from zero, timing

       TH1=TL1=0.

       S0=1.

       S1=1.

       S2=m&0x01.

S3=m&0x02.

       OE=0.

       TR0=TR1=1.

       while(TL1<250);

       TR1=TR0=0.

       OE=1.

       time=TH0*256+TL0.

       return(time);

}

void main()

{

    uint temp；

    RS232_init()；

    OE=1；

    while(1)

    {

        temp=color_display(get_char())；

        RS232_init()；

        send_char(temp/1000)；     

        send_char(temp%1000/100); 

        send_char(temp%100/10);

        send_char(temp%10)；

    }

}

The serial port is used to select the channel for the color type, and then the different colors are determined because they correspond to different times (with the same counting values).
