The schematic is attached. The code, using c and the xc8 compiler for the pic18f46k22. I'm making a traffic light controller for 4 different lights. i set the delay to just 100ms temporarily. i'll fix that later and set it to loop so i get 5-15 second delay. /* * File: main.c * Author: IBRAHIM LABS * EMAIL:
I get the feeling they have been adding more sensors in the system, to detect the number of cars waiting in each lane (including the left-turn lane). I suppose it's for certain there is a computerized device making decisions at the busier intersections. What I often wish is for is that the system would hurry up and give me a green left arrow, wh
Hi every one, I just joined this forum. I would like to do a project for traffic signal control. At present, our existing system is having 3 Digit 7 Segment LED Display as timer (to show the remaining time in seconds) and three lights RED, YELLOW & GREEN (as general standard) for each direction. The timers in every direction shows remaining time
First glaringly obvious problem are these lines: IF (reset = '0') THEN IF(CLK'EVENT AND CLK = '1') and car_detec = 1 THEN This isn't a synthesis template for an inferred register in VHDL. The synthesis template looks like this: -- asynchronous reset rising edge triggered flip-flop dff: PROCESS (CLK, RESET) BEGIN IF R
Hi all, Am a new member here and hope to learn a lot from this esteemed website. I have a vhdl code that compiles fine. The only issue is am not sure about the shape of the wave form because my Web Edition Quartus doesn't allow me to do so. Can any one help me to see the waveform shape for my code please? the code is library IEEE
I don't see which aspect of a traffic light controller could be better simulated with Proteus than with Modelsim and a suitable testbench. It might be that you just don't understand it's capabilities.
Hi, I got this instruction given: > For each of the following three scenarios, initially assume that the East-West traffic has had a green traffic light for a long time. 1) If a North-South car is detected then the traffic lights will cycle to green in that direction. The walk light will not be on unless a pedestrian is detected then (...)
I just draw the above diagram for modeling purpose. Due to its simplicity, a counter Modulo 5 ( 0-4 ) could do that. Once you specified working behavior for each light on an inverted logic for another, in fact you would deal with a single variable. You probably is aware that a real word traffic light is not so simple. +++
If you have project where you need to run several tasks parallel then RTOS is good to use. Every task has it own priority, so RTOS takes care what tasks to run more often. If you have one hardware which more tasks use then you must use some kind of traffic lights (similar to sharing in widows) to be sure that only one task can use that hardware in

Dear all, My friend have an assignment in the Micro-controllers course, he has to write an assembly code to control a traffic light using PIC16f877a attached to a 7-segment display s the following flow chart 90928 the circuit in Proteus is attached below 90929 I look for your help as soon as possible
The CAN bus utilizes a Message ID centric system, in contrast to Ethernet which is a Node ID centric system, this approach allows a node to receive virtually all traffic on the bus. The messages received by a CAN node can be limited by the use of an Acceptance Filter, which determines the messages accepted by its
dear all, i am working on traffic light controller using atmega32. i am not getting the logic behind keypad. actually in traffic controller we have to enter the date, time, signal working time, slot time, red time, green time, yellow time and many more entries. at starting we get a message ''press any key'' at LCD. know (...)

So far i have initialised all the input output ports. 75394 THe only part i need help with is the flowchart on the right. This is a traffic light controller to display three characters in the middle of the second line.
so many projects those you can create. 1) temperature controller. 2) traffic light controller. 3) led chaser. these are simple projects.
Hello, everyone .....if we want to write the test fixture for traffic controller, and then I put one Po(Power outage) mode to control light and the two RED light will blink. However, If I want two of sequence of stimulus into the test fixture: S0 => S1 => S2 => S0 S0 => S1 => S2 => S3 (10 clock cycles) => S4 => S2 => S0 How to I start with tha
if you set the CAN mask to 0x00000000 do you receive anything? it is worth getting a CANBUS analyser so you view the traffic, e.g. CANUSB - The Low cost CAN to USB converter

I feel you do an intelligent ambulance along with intelligent traffic control systems, where you will keep green light for more duration and less time if the traffic is less.... and make all the signals red if an ambulance comes in any directions and make only green light for the ambulance and vehicles to pass....
kindda.... am actually interested in makin traffic light controller using intel 80C51BH.... can u help me out???!!!

what exactly is your problem - are you missing TCP/UDP packets ? how much traffic is there? I have used a PIC18F97J60 (which has an onboard Ethernet controller) with various devices attached (LCD, LEDs, barcode reader, RTC, IO extenders, etc) without problems. However, the traffic was low consisting of a data UDP packet transmiited every (...)

can anyone tall me wat all variations i can do in my traffic light controller design using VHDL em only doing the controller part.
A traffic light controller sounds like the job for a simple low-cost microcontroller, unless your goal is to learn FPGA design. An FPGA can give extremely high performance if you design a parallel processing algorithm that takes advantage of the FPGA's architecture. If you simply drop a microprocessor core into the FPGA, then you will get (...)

Search on internet for "traffic Ligths". Some links:
Refer to this book i think it has the traffic light controller designed! Advanced Digital Design with the Verilog? HDL * By Michael D. Ciletti. * Published by Prentice Hall.
You can look at this book by Randy Katz, Contemporay Logic Design, 2nd Edition. They have specific example on TLC. Chapter 9. case study traffic light controller. very good book on FSM designing.
You can design a traffic light system, it can be done with discrete gates or with a pld, such as a GAL.
