Free Project - 245 LED Display

[Pic_User]

hear this. , mr trent give the scheme, the VB program, the hex for the PIC . All this should be ok... idon`t have do some tests if all the documentation is complete with the information. If you say to do tests then the HEX for the pic if broken. If you have build the board , you have program the PIc with the hex am plug it on the board and work... NO??? . No changes in the hex or anywhere else.

Hi Mr. Magu,

Welcome to the MELabs PICBASIC Forums.
We are a diverse group of people.
There are people of all levels of capability, and reasons to be members of this forum.
The common thread, in general, is PIC chips, PICBASIC (PBC) and PICBASIC Pro (PBP) code, and electronics related to the same.

Nobody is paid to moderate, read or reply to members posts.
There is no one assigned to solve problems.

Some of the members help greatly by posting projects and project ideas. Some, help by answering other member’s PBC or PBP questions. Mostly the knowledgeable members spend hours of their time answering thousands of questions. They do this without pay, without gain. Just to help each other out. I learn every day.

Skimask and Trent and the others have replied to your post repeatedly. The common reply to you is: Start smaller. Gain experience. Work your way up circuit complexity. Work your way up programming complexity. Gain an understanding of the process, and the method.

You don’t want to invest the time and effort. We understand you have invested a great amount of time, effort, energy, money, frustration. Because, you have “hardwired” the completed circuit, you are reluctant to test a piece of the circuit at a time. You would have to pull the completed project apart, or buy new duplicate parts. This is a real problem for you.

Fakhzan (fazan83), was nice enough to write special code for you, to help you, find the problem. He took the time to write the code, and explain the process, to start you on the “trouble shooting” process. This is a brilliant “way around” your dilemma. Test the finished project, with a custom testing program. Great idea Fakhzan!

If you would consider what these knowledgeable, engineering professionals would receive in compensation (pay) for the same number of hours consulting or engineering. These people have invested more into answering your questions, for your project. They don’t have a problem. You have a problem. Demanding that others answer your problems, while refusing to even try any of the suggestions, shows that you, obviously have no idea how this great forum works.

So my suggestion to you:
Start smaller.
Gain experience.
Work your way up circuit complexity.
Work your way up programming complexity.
Gain an understanding of the process, and the method.
Added:
Gain an understanding of the forum, and how it works.
Read previous posts, for hours.

The main problem seems to be, you are one project oriented, and focused. The forum is focused on always learning a little more then we already know. Step by step, never giant jumps in knowledge. Build projects a little more complex each time.

If you wanted a scrolling LED sign that works “right out of the gate”, you should have just bought the commercial, finished product, that Trent linked to. That is not what the forum is all about.

If the project worked for Trent and others, it is impossible for anyone, to just tell you why your project is having trouble. You are the doctor with the patient. If you built it. If you programmed it. You must “trouble shoot” it. Refusing to consider helpful suggestions, demanding help, is not the correct path.

We are sorry that your project is causing you pain. I think most of us have been there, “a project too far”. A project that was too big for our experience. When it didn’t perform, we had no idea what to do. A costly mistake in time and money, but a lesson learned. Then, we can come to the forum, with advice for others, to not do the same.

i have a relativy simple question about the montage of the board. The ELECTRO CAPS where do i have to place them?

[magu]

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?

If I hear about people submitting my work as their own ... <h2><pre style = "color: red"> Watch out!</pre></h2>

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:

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.
