Display LED programmable using PIC16F876

- -- Read description for schematic and software
Is a display formed by 7 rows and 24 columns of LEDs. I'm using a PIC16F876 programmed by me in assembly. With 3 buttons you can set the word to show selecting letters and numbers. | È un display formato da 7 righe e 24 colonne di LED. Ho usato un PIC16F876 programmato da me in assembly. Con 3 pulsanti è possibile impostare la parola da mostrare selezionando lettere e numeri.
----Update----
I've also made a C library for this display (this is not the code running on the video, library will just interface with the display)

Simple example that will print "Hello":
void main(void) {
LD_Init();
LD_PrintMode(0);
LD_Clear();
LD_Print("Hello"); }
You will also need to setup an interrupt that constantly refreshes the display: (in this case i'm using a 16mhz osc)
void interrupt refresh(void) {
LD_Refresh();
TMR0 = 100;
T0IF = 0; }
If you want to scroll the text you will also need to setup your text length with the LD_SetTextLenght function so that text will scroll only until your limit and not until the maximum text size.
----Update----
-Pressing the right button during the scrolling, now you can set the scrolling speed.

Program code: www.dropbox.com/s/nlfvbn1g6cq...
Components used:
- 1x PIC16F876 (20Mhz)
- 1x 16Mhz Crystal
- 2x 22pF capacitors.
- 32x Transistors BC547c
- 168x red LED (3mm)
- 24x 100Ω resistors
- 32x 1KΩ resistors
- 3x 10KΩ resistors
- 3x buttons
The program is commented in italian so if you have any question you can ask me.
Unfortunatly there are still some troubles when you write something because some times it skip 2 letters instead of 1, you can go 1 block back pressing fast 2 times the central button. - Jak na to + styl
I don't understand. You have 168 LED and only 28 pin on mikrocontroller. How you control 168 with 28? And I/O Ports 22?
Nice project brother. Thanks for sharing on the video.
@Mrsameero
Thank you so much !!
I Couldn't Thank you enough really thank you
and what a great work you did there :)
felicitaciones muy bueno
Nice video, thanks :)
What is the difference between PIC16F876 and PIC16F876A?
Nice show ...youtubers need schematic man !!
thank you master
thank you
Well actually yes, I've used it for a little bit of debugging too. I had some issues with timing, you can't simulate it in real time (I mean setting the pic with a 16Mhz clock) because of the fast display refreshing. The program become really buggy, gives you some error and it don't work as well. So it's better to set the pic frequency to some hz or as much as you can before you get errors. That's the only problem, for the rest it works good.
Hello. What is the program with whom you have scheduled the PIC16F876?
Sure you have used PIC16f876 ?
Great!
thousand applause!!!!!
Best project
Excellent video but no voice. Great work.
@Mrsameero Here you are =D. Added into the description the last code version + the circuit schematic
how to connect microcontroller to led boards
sir
Good evening, thank you for your answer, but it is not on your circuit operates with a 16F876A, in principle, the program must be slightly modified, well I think, but I'm an amateur, thank you for your help. Cordially. JM
Can anyone plz confirm if that project also works with 876A? From the below comments i only see that it should but nothing confirmed.
Thanks, I've uploaded the last version again. Link is in the description.
I m intrested to make this one but can't understood how it's made ,I have all materials but don't know how to build this
Hello, thank you, PERFECT, I will make your edit again BRAVO to you for your achievement, SUPER, see you soon. JM
this is exactly what what I've been searching net long ago for. please sir can you help me on the circuit diagram. nice one.
I have did this project... but he don't work... i have problems with the scheduling....
which compiler u r using for pic16f876
I forgot, last question please, the PIC 16F876a is the model. Thank you very much. JM
Great! project Congratulations! great Hug Eli PY2EGS from Brazil. 73 TFA.
It's a 16F876 but i think that it works also with 876A
Hi how can add effect in display up down fading flashing left right
Main connections you hav hidDedn how can it's made
please, as the transistors are called
is possible to simulate in Proteus???
Hello, could you please just confirm for me if it's a PIC 16F876 or 16F876A x, because I only have the 16F876A, thank you for your response and good weekend. JM
how i upload this code to the ic microcontrollar
Sir how can program install in Microprocessor please tell me this kits
Nice video plz make it again with diagram n instrument name plz sir.
Possible pour nous de mettre un programme complet par isis protese et mickro c sur fichies winrar plz
I can't understand the programming plz can you explain this
pls help me to build one by demonstrating the method step by step thanks
Porq no muestra como se hace
I like your projects
Can u show me how tomake some
oowoooo
how many letters can remember
Please explain how to make it please send a film of it
How I make it..
I need the diagram
Please sir I need just the schematic diagram of this one in understandable way. thanks
Please give me it's circuit diagram thank you
approx cost of project ??

Good work
Tell about source
plz diagram
Where is the ic pins connecting the 3 buttons?
This circuit create you
digram aur banane ka tarika aur meterial bhi bataiye sir plz
Sir please give me circuit diagram
plz send circuit diagram bro
hav seen ur code.. u cud use the de command for letters definitions....anf uur code cud get very very easy.. hav worked on it to make it compact..vl upload later.
thanx for the method
Schematic plz
Please give circuit diagram...
हम भी ऐसा प्रोजेक्ट बनाना सीखना चाहते हैं
Ok
can you please provide the circuit and the code?
bonjour donnez moi s'il vous plait le schema del'ensemble
Hi ax866, this pic's project is new for me, i do work on electronics repairs for long time but, nothing like ic burn,
i'm trying work on you project but i do have so many problems like:
1-i do not have i ic burnner and i use the jdm on the serial port
2- i have a pic16f876a
3- i got some error when i try progamming a device ( unknow device, verify error 118 read 3ffff and some
other thing is, when i put the assembler to run the file, this keep stock on this line
delay_sicurezza_0
decfsz d1, f
goto $+2
decfsz d2, f
goto delay_sicurezza_0
;3 cycles
goto $+1
i'am not sure if this is problem or not, but i realy need your help
your project looks like amazing and so easy to do, i'am wait for this and thank you for now !!!
hi again x866, thanks for reply me and sorry for the late, ok?
whell, did i stop to work in this project for month, because i'am busy and did orther the right parts but,
i get the original pic16f876-20/sp and pickit2 so, i'am still get the problems with this code,
before i try to progamming this by a serial port, everything say progammed without erros,
when i put the ic on the circuit nothing work, ok i get the pickit and this guiveme to many errors,
could you please help me on this, because i do not understand what i have to do with mplab and the code,
i did see videos tutorials a lot from youtube about mplab, some videos tell to use source files,lkr,inc and more.
i try all and not able to fix, can you send the hex file for me try work or maybe you say what i have to do,
i need finish this, thanks for now !!!
Good evening, first of all thank you for your achievement, SUPERB, thank you. Could you possibly give me the program code for the link would no longer works nice, thank you very much for your help. Cordially. Jean Michel
have you tried this
Ai lite tar diagram ta dile and ic no ta dile khub valo hoto
