How to use 16f877A instead of 18F452 in LedMatrix

[ilker_32]

ledmatrix.dsn

hi, There was the problem in my computer... And , I was interesting with it...

sorry, i can't understand you...

but, there isn't standart DOT and it can change their pins...

if there is the datasheet you can use it... if there is not,

you can use multimeter...

again sorry.

HI ilker_32 I AM FROM CHILE SOUTH AMERICA AND I JUST PROGRAM IN ASSEMBLER. YOUR MATRIX WAS VERY WONDERFULL.
YOU CAN USE THE RS232 PORT???:?::?:
CANT YOU POST THE DSN FILE I HAVE PROTEUS 7.5 TOO
I VERY THANK FOR YOU
GOOD BYE FROM CHILE
MY NAME IS MIGUEL VALDIVIA:arrow::arrow::arrow:

Hi Miguel. Thank you very much.

i'm using the Proteus 7.5 sp3. And, i gave link for the Proteus 7.5 sp3. (download)

How you are taking one error?

And, when you take, write the error here.

for the RS232,

you can use virtual terminal of the windows.

is it Ok,

take care of your self.

and,

you visit CHILE for me. That place is appearing nice.

thank ilker 32 ,but I just wrote to congratulate you
your matrix is very wonderfull , i want to know if program this matrix across
to rs232 port.remember i program assembler basically.cant you post the dsn file,
i have proteus 7.5 in my computer
thanks and write you soon

Hi ilker 32. i have gone through your posts, though i have not looked into your design but your ccs c coding fascinated me as i'm learning CCS C. I hope you will be disposed when need be. You are already doing great with your English. I hope you understand me. My regards to Sofier.

Eğer bana DSN kimse bunu denemek için dosya göndermek teºekkür ilker_32 çok teºekkür ediyorum
hi from chile
you understood what I wrote
just google ¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡

Added after 13 minutes:

but your led matrix was done in C language


or not




hi from chile

 

[ilker_32]

expinsives hous in the india

i'm thanking to everyone...

i have anothrer question for you, waht is your pic basic compiler????
thanks and i`ll see you soon

for that, i put the MCSP.

@porotot, which language are you useing?

---

please, correct my wrong writings.

example:

no : Eğer bana DSN kimse bunu denemek için dosya göndermek teºekkür ilker_32 çok teºekkür ediyorum
yes : .DSN uzantılı dosyayı deneyebilmem için bana gönderebilirmisiniz. Teºekkür ederim.
yes : .DSN uzantılı dosya üzerinde deneme yapmak istiyorum. Onu bana gönderebilirmisiniz. Teºekkür ediyorum.

you can download DSN file from here:

(use the Proteus 6.9, 7.0, 7.1, 7.2, 7.4, 7.5)

thanks very much
i am using assembler and a few of basic
but i am not a perfect programer ok
I can understand what you write a lot

Ben 8 * 32 yapmaya çalışıyorum matris 74hc595 ile nokta. Do u nasıl 74hc595 bağlamak için biliyorum (pin 11, 12, 14 pic16f628A) için?
Nasıl sağdan sola kaydırma mesaj kodlama için gerekir. I like Sadece küçük bir kod .... EDABOARD "HOŞGELDİNİZ iletiyi görmek için" istedi

@supra_56,

ilker_ekener@msn.com

perhaps, i can be helper to you...

 

[vaniajennifer]

hello everyone..could you please help me? I'm a graduating computer engineering student..our design project is about led matrix..It will be 2 rows of 12 8x8 led matrices..if anybody would be sooooo good to help me..please send me a schematic for the led matrices and also a program..i don't know how I will program it using assembly language in MPLAB IDE..the pic is PIC16F877a..thanks

please telle me how i send message via rs232
is dont work

I have No problem With Compiling .. i Compiled the Code successfully

I tried Your New Code

long s1_char_size=23; 
char s1[23]; 
... 
.....                      
const char   msg_default[23] = "1234567890"; // 10+13=23

But Also the Same Message Appears After 59 Second

Also the first Code have the same problem After 27 Second

long s1_char_size=26; 
char s1[26]; 
.....
..........
const char   msg_default[26] = "sofie & ilker";

**broken link removed**

Try to run the Project for 5 minites .. If this message didn't Appear with You .. then the problem My Be in MY Computer

Is the Problem In Your Name ("sofie & ilker") Or What Just joke

Re: 16f877a dot ledmatrix 8x8

8 minute for you
**broken link removed**

AND...

I am not trusting to the Proteus....

sir is your row here is cathode and your column is anode? in your row what demultiplexer you used? and what specific components to be added in the row? and also in the column.. what is there to sink the current? because i want to implement in real hardware.. and i want to know whats the components of this project.t

 

[supra_56]

Both r using 74HC595. On the top is connected to portB is column and rest is connected to portC is rows.

 

[cuber18]

Both r using 74HC595. On the top is connected to portB is column and rest is connected to portC is rows.

so whats your row? anode or cathode? you have full schematics on this? including the transistors and resistors you used?

 

[supra_56]

so whats your row? anode or cathode? you have full schematics on this? including the transistors and resistors you used?

Using same schematic that ilker_32 posted on this forum or the one u posted it. I used common cathode(usually i have bi-colour dot matrix). No need to used transistor or resistor. 74HC595 can handle up to 20 or 25 ma.

Fortunately, i used resistors for rows. Also can be used unl2003. Can u do same schematic as u already posted it?

you have common cathode? so that means your row is cathode?

you can download my project here..

https://www.edaboard.com/threads/199151/

im using 74hc154 in my rows.. and i dont know what transistors to use to sink up my rows current.. i have 7x40 led matrix which is 7 cathode rows and 40 anode columns.. in my columns, i am using 74hc595 and what resistor or transistor should i add up to sink my columns? need help on a real hardware design.. because i want to implement this with less errors.. thanks!
