TCS 3200-DB Color Sensor Module

B.ASHISH · 2012-04-25 07:12

I'm using Parallax DB Expander to interface the TCS3200 color sensor module on the propeller demoboard.
I fixed the sensor module to the db expander but the leds are not glowing when I gave +5v from the demoboard to the +5v of the db expander and GND of demo board to that of DB Expander.
Please help me with all these basic connections.I already got the code.

The LEDs are turned on by your program and not supposed to come on as soon as the module is powered up. Have you tried running the code yet?

Yes sir ,I tried running the code,but still LEDs are not on.Is there any additional connection I need to do?

Please post your code.

Sir the sensor is running.It is displaying values for red,blue,green.When red object is placed in front of the sensor,the value of red gets reduced.Here,s the code.

{


This is the example code for the TAOSDriver. Pins are connected as follows:


0 = PinC = OUT
1 = PinD = LED
2 = PinE = S2
3 = PinF = S3


The method calls are as follows:


taos.getClear(PIN)
taos.getRed(PIN)
taos.getBlue(PIN)
taos.getGreen(PIN)


Where PIN is Pin 0 (OUT)


When running this code, open the Parallax Serial Terminal and set the Buad to 115200. You should see simillar:


Clear = 125
Red = 131
Blue = 512
Green = 142


}


CON
  _clkmode = xtal1 + pll16x
  _xinfreq = 5_000_000
  
OBJ
  taos : "TAOSDriver"
  pst : "Parallax Serial Terminal"


PUB main


pst.start(115200)


repeat
  pst.Clear    'Clear screen
  pst.str(string("Clear:"))    'Clear sensor readings.
  pst.dec(taos.getClear(0))
  pst.NewLine
  pst.str(string("Red:"))      'Red sensor readings.
  pst.dec(taos.getRed(0))
  pst.NewLine
  pst.str(string("Blue:"))     'Blue sensor readings.
  pst.dec(taos.getBlue(0))
  pst.NewLine
  pst.str(string("Green:"))    'Green sensor readings.
  pst.dec(taos.getGreen(0))
  pst.NewLine
  
  waitcnt(clkfreq/10 + cnt)

The values it is displaying,(though they are varying continuously) is;
Blue:1416
Red:876
Green:1157.
I am not able to understand what these values indicate.

Where did the "TaosDriver" program come from? Can you post it here, please?
