LCD Rolling Odometer Effect

[Art]

Hi Guys,
Has anyone done the rolling odometer effect with PicBasic?

I've done it with 7 segment displays which is on YouTube as a response to the above video.

Now I think I can have the effect on a 2x16 LCD with PicBasic.
Last time I got stuck, and now am pretty certain about what was breaking my code.
In short, you have to write to all the LCD custom character RAM you want to
use for a given frame before printing the frame on the LCD.
I want to make a time display work that way because I'm working on the program currently.

Art,

Nice project. Take a look at Mister_E calculator. It can be downloaded from the next post. Look at the last button "LCD Custom Character". I think you might be able to do it from there.

Hi, Art

Just a shifting Game ... ( Darrel's courtesy ...)

I took a "9" in reverse "rotation"

  LCDOUT  254,64,14,17,17,15,1,1,17,14     ' Cust Char #0
  LCDOUT  254,72,0,14,17,17,15,1,1,17      ' Cust Char #1
  LCDOUT  254,80,0,0,14,17,17,17,15,1      ' Cust Char #2
  LCDOUT  254,88,0,0,0,14,17,17,15,1       ' Cust Char #3
  LCDOUT  254,96,0,0,0,0,14,17,17,15       ' Cust Char #4
  LCDOUT  254,104,0,0,0,0,0,14,17,17       ' Cust Char #5
  LCDOUT  254,112,0,0,0,0,0,0,14,17        ' Cust Char #6
  LCDOUT  254,120,0,0,0,0,0,0,0,14         ' Cust Char #7

see how difficult it is ???

just shift values left or right for normal or reverse "rotation" ... then load the custom characters memory ... and print

Sooooo Easy ...

I have one digit rolling now, so the others won't be too hard.
I used this for the data table:

DATA 142,145,147,149,153,145,142,128 '0
DATA 132,140,132,132,132,132,142,128 '1
DATA 142,145,129,130,132,136,159,128 '2
DATA 159,130,132,130,129,145,142,128 '3
DATA 130,134,138,146,159,130,130,128 '4
DATA 159,144,158,129,129,145,142,128 '5
DATA 134,136,144,158,145,145,142,128 '6
DATA 159,129,130,132,136,136,136,128 '7
DATA 142,145,145,142,145,145,142,128 '8
DATA 142,145,145,143,129,130,140,128 '9
DATA 142,145,147,149,153,145,142,128 '0

Although for a clock display, the MSD of the seconds,minutes, and hours
behave slightly different because they roll over to zero after 5, 5, and 1 respectively.

[Art]

Not quite done yet, the hour digits don't yet rotate, but you can't tell that in the video.
The project is just an internet retrieved time display for another internet enabled project.

What would I do if I didn't have you guys to give me ideas to play with.

I know you don't need help Art, so don't look at the code till you're done.

Thanks.

Do you have the Elapsed.bas include file? http://www.picbasic.co.uk/forum/showthread.php?t=3251&p=17473#post17473

[SKOLS1]

No,but now I downloaded,where I have to put this file now?
Please explain me where to put this bas file!

[ScaleRobotics]

It needs to be saved in the same dir as the code you are writing.

[SKOLS1]

I make new folder in the C:/Program File/Mecanuiqe/MSC/NEW FOLDER
and In the new folder there is the compiled code and Included file Elapsed.bas.I compile it,but now I have another problem.It says this ERROR: Variable wsave3 position request 416 beyond RAM_END 335.
What is this??

OK,I compile for PIC16F877,and it's working.But when I hold the Button RA3 it's not working,I mean the clock it isnt working

[ScaleRobotics]

Open ASM_INTS.bas and follow the instructions

' --- IF any of these three lines cause an error ?? Simply Comment them out to fix the problem ----
wsave1 var byte $A0 SYSTEM ' location for W if in bank1
wsave2 var byte $120 SYSTEM ' location for W if in bank2
wsave3 var byte $1A0 SYSTEM ' location for W if in bank3

(also, there might be a newer elapsed.bas that uses DT_INTS. Does anyone know where that is?)

Yes, but (I am sure it is right in front of me) I don't see a place to download the elapsed code from there. It is obvious for the INTS-18 though. The link to PBPGroup has an Elapsed that has Include "ASM_INTS.bas" ' ASM Interrupt Stubs, but I am thinking there is one for DT_INTS.

[Darrel Taylor]

DOH!

You're right, there's no download.
I used to have it in the main .zip file, but it's not there in the latest version.
I'll put it up again separately.

Thanks Walter

it's ok,it's working now. I made it.
