    and for those who had build the proj and it work. I think the HEX is incorrectly. do you program the PIc plug it on the board, next plug the eeprom and start.? there are ben no problems?

    i use your artwork for the proj. So don`t wory.

    Hi Magu,

    I got your private message.

    We will test the board based on these schematics and pictures:

    Display Schematic.pdf (Post #1 of this thread).
    Controller Schematic.pdf (Post #1 of this thread).
    Your picture lm.jpg

    In this post we will test the 245 LEDs and all the transistors.

    Before we test the LEDs:
    Code:
    Remove all the ICs from their sockets with the exception of the 
5V regulator 7805 which must remain soldered on the PCB.
(Put the ICs into antistatic bags).

Replace the seven 18 ohm resistors with seven 180 ohm resistors.
(See Display Schematic.pdf). This step is mandatory!!!!!!!!!

Solder two insulated wires (about 50 cm each) to +5V and at the
other end of the wire solder a 1k (1000 ohm) resistor.

+5v-----------------------------/\/\/\-- (P1)  
    (50 cm insulated wire)    1k resistor.


+5v-----------------------------/\/\/\-- (P2)
    (50 cm insulated wire)    1k resistor.

The end of the first resistor will be called "P1" in the
instructions I will post in this thread. So put a label
on that resistor and write on it "P1". Do the same for the
second wire and write "P2" on the label.
    Code:
    TEST 1

T1/Step 1:

Apply 12V DC to the input of the voltage regulator and measure 
the voltage on its output which should be between 4.9 and 5.1V.
    Code:
    TEST 2

T2/Step 1:

All the ICs must be removed from the sockets, with the exception of
the 5V voltage regulator. The seven 18 ohm resistors must be replaced 
with 180 ohm resistors.

    Thumbs down listen here

    Have you noticed that the “one project”, posters.
    Whether or not they are students like eng444, AlaskanEE or Magu, or the multiple personalities building a DMX512.
    Want specifically their project. Not general answers, not how to proceed, but precisely what is exactly wrong with this single project.

    As Skimask has said (many times):

    You would think:
    Anyone who has sat in classes hour upon hour, day after day, year upon year. A student that has spent hours learning in labs. A student that has spent night after night studying for exams, passing those exams. Learning “state of the art” for years.
    Paying many years of income, to professional instructors, that are not only specialists in the industry, but at a pinnacle of expertise to profess knowledge exactly on the subject.

    A student, that will be stepping out of the door into a world of professionals. Ready in every way to become a highly paid professional.

    You would think:
    Those students, doing their final project, would know how to conceive, design, build and “trouble shoot” a simple project.

    However:
    There are a certain few, that have sat in class rooms for years. Spoon fed everything they need for the exams. Told what chapter, what material will be on the exam, so they could study from this paragraph to that paragraph. Led by the hand to lab. Told where to place the test leads, how much to turn the controls, what the instrument’s indications meant. Mostly their questions were, “is this going to be on the exam?” or “can I copy your home work?” or “what did you get for number 4”.

    When they get to the forum, they expect specific instructions, precisely when they want / need it. They expect a “lesson plan”. When they sense a “dragging of the feet”, they get belligerent, rude, and demand that the “instructors” give them the information. The forum seems filled with the worst instructors they have ever paid for.

    I don’t know how they could do all the school work, without a love of learning, a love of technology. They have my admiration for their tenacity. That is a huge pile of work that they “toughed out” and “plowed through”, so they can work in a field they don’t care about.

    To use a project directly, “as is”, without significant improvement, modifications, is the height of dishonesty. Without proper credit given to the “seed idea” fully revealed, and disclosed is stealing. Intellectual property is property. Any student that would do such a thing, didn’t learn in the “professional ethics” class either.

    These projects are so far over the ability of the this type student, they do not have the ability to know how any part of it works. This makes it impossible to figure out what is wrong. The same is true of their conduct in the forum, and in life. I feel sorry for the company that makes the mistake of hiring them.

    Shame

    Ohm it's not just a good idea... it's the LAW !

    Perhaps this is an attempt to avoid being sued under Health and Safety legislation. They tell them exactly where to place the leads so they dont blow themselves up.

    Some of us had to learn that the hard way but we survived

    Hi Magu,

    For the next test you will need a signal generator.
    (5V square wave of about 1.5 Hz).

    If you don't have a signal generator, build this circuit:

    (Click to enlarge the picture).

    Let me know when you have the square wave signal ready.

    Best regards,

    Luciano
