hello, i require a code for traffic signal control with level sensors using M68hc11 micro controller . i am in need of this code if any body have the code then please send it . your's friend shiva prasad hanchate |

Wow! Two traffic signal questions in the same day! You two must be in the same class.
I assume that the level sensors are measuring traffic congestion, and not, let's say,
rainfall! lol. if this is the case, then the code that I posted in the "files"
section of this group will need to be modified in order to accomodate the
"level" sensors. One might use a few Hall effect sensors for simplicity. If you
used 4 sensors for every two lanes-- 4 for each direction of a two-lane road-- then you
could use a 74hc595 chip to latch the data from the 8 sensors and serially send them to
the 68hc11. What makes the 595 chip the perfect match for this type of setup is that they
can be cascaded, so there is almost no limit as to how many one uses. I encourage both of
you to put forth more effort to write your own code rather than have somebody else provide
it for you. I am all for helping somebody that helps themselves, in other words, why not
attempt to write the code and then post it on the "files" section of this group for all to critique, this way you are not asking for someone else to do your homework, rather, you are putting forth some effort and in return getting it right through the cooperation of all parties involved. Take care.

hello i am trying for the code if i could get some then i can check were i am going wrong that is why i asked for the code ... not putting my efforts and asking is waste for me and my capability. thnx for ur suggestion ..... once again thnx for ur reply waiting for ur reply take care bye.... --- bart homerson <> wrote: --------------------------------- Wow!

Shiva, Let me add my support and comments, Bart and Scott both address an important point. What you are asking for the end result (programming code) of a system that has no clear definition as yet. How many lanes of traffic will be controlled?, how many sensors will be on each lane? Will there be turning traffic? Will there be more than one intersection? is gridlock a factor? (that is can traffic back up between intersections until no movement can occur for cross traffic?). More importantly is this intended to be a "real life" model? or lighting for a model train layout. Essentially your question is much to vague to program a solution to. There is a resource to use here to get guidance for this kind of problem, but we need to know what the problem is.

Shiva, Let me expand on what Jim Peterson said. > What you are asking for the end result (programming code) of a system > that has no clear definition as yet... <soap_box> Problem solving 101 Step 1: Define the problem. I hate to say it, but you have failed miserably. Moreover, if you don't improve, you will be doomed to be a grunt. You will have to depend on someone else telling you what to do and how to do it, and then that someone else witt have to check if you have done it correctly. Your marketability will be dismal. By far the most important step in any project is what is called Requirements in software engineering. It is often the most neglected step. And neglecting this step costs tons of time and money. Yes, Shiva, you are not alone. Study after study has determined that most software developers spend most of their time rewriting, fixing or modifying existing software and the most common reason for this is related to Requirements: Flawed Requirements, ambiguous Requirements, incomplete Requirements... On the positive side: Get the requirements right, and the battle is more than half won. Concepts start to flow and the design and implementation follow smoothly. And you know that the job is done and done properly when every requirement is met. Value Requirements and your career will skyrocket. Ignore them and expect to remain a grunt until you retire.
