Awesome, Pete.

Thank you

Hello ,
i try to make this cube , with PIC 16F628A , and it'a working , but the boton line is light too low .
The boton line is conected to pin no.4 , RA5/MCLR.
It;s this the problem ? Where i conect the boton line to working like other line

If you use the code posted on post 294
IT hooks up on PORTA.2 turns on layer1
PORTA.6 turns on layer2
PORTA.7 turns on layer3
PORTB 0 to 7 are led's 1 to 8 and PORTA.3 is led 9

MCLR is input only and portA4 can only sink power and all the posted stuff would of been better if some dummy being me would of used better names for my sch and looked to see if the right one got posted.

When I did the change from the 16f690 I did this for a bunch of chips and some of them could RA5 I had a bunch of kids making these. Ran out of 16f628a fast and 16f690

i try to change , but now i have two led not working

 

[metrix]

Nice cube real nice

 

[sahu]

any body can provide its (3x3x3 LED Cube) CCS C source code ?

Need Help
I made the LED cube given in this site and with 16f84a it worked fine. Then I tried to modify the assembly code to use 16f628a. With the new code cube works for nearly one minute and then it stops at one random LED pattern. Can anybody guess what would be the problem? I used RB0-RB7 & RA0 for LEDs and RA1-RA3 for layers.

Post your code and I'll help you

 

[be80be]

Hard to tell without code your life using

Hello be80be,

thank you for quick response. Here I have attached both the original code for 16f84a and the modified code for 16f228a.

I simulated it with Proteus. It gave me the following simulation log.

I having some issues. The cube is working "almost" fine. Just in some routines, it seems that RA5 is on all the time. So, the bottom layer keeps with the 9 led's on. I made the project with your original codes that you gave us here: https://www.electro-tech-online.com...6f628-instead-16f690.87897/page-4#post-715727 and this sch: https://www.electro-tech-online.com/attachments/16f628led-cube-png.27668/

I was working on that cube (controlled by audio). I share my work with you. Feel free to try it:

Isn't the RA5/MCLR pin an input only pin on the 16F628A?

Take a look to the original schematics...

 

[be80be]

The problem here is I posted like four sch four this each with the same name and some how people get the wrong one and end up putting a roll on the wrong pin.

be80be That's what I'm using:

 

[be80be]

PORTA.2 turns on layer1
PORTA.6 turns on layer2
PORTA.7 turns on layer3
PORTB 0 to 7 are led's 1 to 8 and PORTA.3 is led 9

Which is the value of that C connected between VDD and VSS?
