Color Sensor (ADJD-S311-CR999) and PIC 18F452

ali_cmi · May 17, 2012

Hello,

I am trying to interface a Color Sensor (ADJD-S311-CR999 Miniature Surface Mount RGB Digital Color Sensor) with PIC 18F452. This sensor communicates with a peripheral using I2C protocol and is quite handy (as people say it).
The problem I am facing is that when I try to read sensor gains, the PIC somehow resets itself although it is being locked in a while loop. WDT is turned off so I guess that reset rules out. I was suspicious of Stack Overflow Reset (don't know anything about it---came to know when I ran into project settings in MikcroC Pro for PIC).
And another amazing thing, unlike the WDT reset which is periodic (2.3s reset), the controller resets randomly as sometimes the whole program executes and sometimes it breaks due to reset.

The worst part: I use Proteus for general simulations (actually I do for all simulations) and it does not have a model for this or any color sensor.

So, I have to debug the code line by line and it is painful. :\

Any help would be appreciated on how to stop controller reset. I have provided the code here.

Also, Please refer to me a better simulation software than Proteus. I know PSpice and Multisim but Proteus is handy for most of the jobs.

You have not provided your code,

Kindly provide it...

and post your schematic diagram.. as well as code...

First of all Check your voltage levels...

The reset you are referring, had occurred with me also, but it occurs only when i had not written my code properly and causes my controller to stop at a some point..

Here is the code and schematic diagram of the color sensor. In addition to it, I am attaching the pin configuration of the sensor.

I have attached an LCD (not shown in schematic) to check the sensor gains for different colors. Also, as I cannot simulate the sensor, I have added code lines to display messages on screen as the code proceeds.

Code:

@ Sir Arun Sharma

Apologies for the untidy code. :-| I have checked my voltage levels and they are as they should be. I even turned off the stack overflow/underflow reset in addition to WDT but it just doesn't work. Also, previously, in the code, the delays were in microseconds, I increased them to milliseconds. The effect I observed was that controller did reset but not so frequently as it did in the former case. (In case of microsecond delays, the controller resets after 1 or 2 iterations of the while loop, sometimes in between and in case of millisecond delays, the controller resets after 7-8 iterations)

The datasheet of this color sensor can be downloaded at https://pdf1.alldatasheet.com/datasheet-pdf/view/203386/AVAGO/ADJD-S311-CR999.html

ı am mading final project.for this project, I need your help.if you help me , ı will be very glad.
ı have a sparkfun adjd-s311-cr999.ı want to separate the ball(red-green-blue) with this color sensor.but ı dont have enough knowledge about I2C protokole(scl-sda).can you help me about pic circuit that scl-sda convert to 3 dijital signal (red-green-blue) in shape of on-off and pic code(picpro basic).thank you for your interest.
