3x3x3 LED Cube - can i use16f628 instead 16f690

[be80be]

There is no C file it was done in assembly.

Hello be80be,

I just finished reading the whole post and I think I'm ready to modify the .asm file to work for my 16f872.

I was wondering what program you use to make your schematics ?

Thank you for your help !

be80be,

I saw in your code for the PIC16f628 the line


movwf CMCON ;turn comparators off (make it like a 16F84)

Should I let it there for a PIC16F872 and why ?

Thanks, I read the awesome Gooligum tutorials (https://www.electro-tech-online.com/custompdfs/2011/04/PIC_Base_A_1.pdf)

and I think I'll be okay to change the other lines for a 16F872

EDIT : I did the first line changes and I'm not sure of these lines

movwf CMCON ;turn comparators off (make it like a 16F84) ?
org 0x0000 ;org sets the origin, 0x0000 for the 16F628 and for the 16F872 ?
movlw d'50' ;delay 250 ms (4 MHz clock) ( with a 16F872, there is no internal oscillator so I'll need to make an external one. With a RC osc (easier) I can reach 3.5MHZ, would it be engouh ? no ? What would be the code to fit with a 3.5 MHz clock

Again, thanks for your useful comments !

Hey guys

It's working !

Thanks for the help !

I'll try to post a video of my 3x3x3 LEB Cube with a PIC16F872 soon.

i want to use 5*5*5 LED Cube with costume animation it may possible ?

 

[Weepet]

Yes, as long as you have enough output on your micro-controller.

5 rows + (5*5) 25 columns = 30 outputs

 

[sahu]

who pic micro-controller ( 16f ) has 5 rows + (5*5) 25 columns = 30 outputs ?

 

[guus46a]

It works perfect

I am also interested in this led cube project but I have a 16F88 Pic. Has anyone written an asm or hex file for this chip?

 

[be80be]

It's not that hard to do just set the chips configure and pints up that your going to use and it should work fine with that chip.

Hey folks, I am also trying to create this cube with the PIC 16F628 and i have went through all the pages of this thread and downloaded all the files.

It seems that every asm/hex file and every schematic has slight variations with respect to the LED lines.

Can someone point me to the correct combination that will work

I appreciate it !!

Pete

 

[be80be]

It's not that hard there one pin on the 16F628 that's can't output 5 volts and thats what made this thread so long lol.

I no longer have code for this but I was going to make a blue one when my leds get here. I'll post working code this week if you want.

 

[amdkicksass]

Thank you so much for your response Burt !!

Perhaps this may be helpful then and save double work, i have downloaded and attached the unique files on this thread asm/schematics.

If you can point me in the right direction id really appreciate it, id like to make a few boards/cubes as gifts for some close people.

Thanks
Pete

This will work

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

*Layer sink with a npn and portb sources the power to the Leds.
And this asm

 

[amdkicksass]

Much Appreciated Burt !!

Does the schematic look right to you corresponding to the code given ?

Pete

 

[be80be]

Looks good

Much Appreciated Burt !!

Does the schematic look right to you corresponding to the code given ?

Pete

Pete, could you write the values of all the external components Please.

Thank you.

Regards,
kv

 

[be80be]

I used 150 ohm on the leds and 1k on the npn

 

[killivolt]

I used 150 ohm on the leds and 1k on the npn

I looked on the other schematics and I think I got that part, I just wanted all the Values displayed on the final to make it easier to read, What value was C2 on VSS? I really like the 2 drawings in Post # 293

 

[amdkicksass]

No Problem at all, Ill update the schematic tonight and repost
