Thank you "Flandango" I really liked the transition of 2 images, do you have a tutorial how to create 2 "pix" to visualize a certain core?

Posted: **Mon Nov 29, 2021 7:54 pm**

See https://github.com/venice1200/MiSTer_i2 ... dification for a little picture howto.
Does this help?

Check this Repository as well
https://github.com/ingloriond/MiSter_I2 ... c2oled_pix
Maybe the picture is already made.

Thanks friend, is there any .pix file viewer for Windows?

Posted: **Tue Nov 30, 2021 1:15 am**

Is anybody who is using i2c2oled with the latest Linux update having any issues?
I am getting errors and it looks like the version of BASH that comes with the latest linux update (Bash version 5.0.18(1)-releasee (arm-buildroot-linux-gnueabihf)) doesn't process string arrays properly and I am curious if anybody else has come across this.

Never mind. I had to convert all files to unix files with dos2unix. While it didn't seem to have a problem with Bash 4.x and 5.1, 5.0.x seems to really not like the carriage returns on each line of the PIX files.

No. But open the file with an textviewer, make a screenshot from the characters and use graphics program to zoom out.
It should looks like...

I am using the pix since the beginning and with the latest MiSTer System, no problem at all.
How did you copy the files over?

Posted: **Tue Nov 30, 2021 1:39 pm**

I had the files on the system since May it was working till my display died a while back.
Just got a bunch of displays for another project I am working on figured I'll toss one on the Mister and that's when I noticed the error on line 350 and after some digging found the issue.
I then pulled down a zip file from Github and unzipped that and still had the issue except that this time I noticed that the S60i2c2oled file errored out saw that it had carriage returns. Converted the scripts to unix format and they worked but still had that error, lit wasn't till after I checked the file format for the pix files that I saw it had carriage returns and converting those also fixed it.
Now mind you, everything works on an older build I tested it on and the same zip file, with carriage returns and all does fine on my ubnutu and msys builds that use bash 5.1.x.
So somehow, most likely during the unzipping process onto the sdcard, the files are processed with carriage returns but I think that's all on my end.

If anybody who uses the TI-994/A core and is interested in some pix for it....

Posted: **Wed Dec 01, 2021 7:45 am**

I added the pix to the Repository. Many Thanks.

Does anyone have 128x64 image collection for "yellow and blue" 2-color oled?

Posted: **Sun Dec 05, 2021 9:19 pm**

Find some Pix here
https://github.com/venice1200/MiSTer_i2 ... ctures/Pix
and here
https://github.com/ingloriond/MiSter_I2 ... c2oled_pix

//Edit
Download the ZIP file from here https://github.com/venice1200/MiSTer_i2 ... s/main.zip
Unzip it, search for PIX.

Voila, you have all PIX I know as I add all Pictures from ingloriond to my Repository.

I'm creating all colors from scratch in the way that I like best, if anyone wants!
Ps. I wanted to learn how to make animated PIX!

Then please upload your pix here in a ZIP file.

An animated PIX is not a real animation, it's just a set of Icons drawn over the base picture at a dedicated position in a timed order.

Here is an Example, it's the "Press Play on Tape" Animation. See https://github.com/venice1200/MiSTer_i2 ... ed.sh#L407

Code: Select all

function pressplay () {
  local t=0;
  showpix pressplay                                       #Load Base Picture "pressplay.pix"
  # Testing Font-Based-Animation
  for (( t=0; t<5; t++)); do                              #Loop
    set_cursor 48 4                                       #SetCursor
    i2cset -y ${i2cbus} ${oledaddr} 0x40 ${itape1}  i     #Draw Tape Wheel 1 with Icon 1
    set_cursor 64 4                                       #SetCursor
    i2cset -y ${i2cbus} ${oledaddr} 0x40 ${itape2} i      #Draw Tape Wheel 2 with Icon 2
    sleep 0.3                                             #Wait
    set_cursor 48 4                                       #SetCursor
    i2cset -y ${i2cbus} ${oledaddr} 0x40 ${itape2} i      #Draw Tape Wheel 1 with Icon 2
    set_cursor 64 4                                       #SetCursor
    i2cset -y ${i2cbus} ${oledaddr} 0x40 ${itape1} i      #Draw Tape Wheel 2 with Icon 1
    sleep 0.3                                             #Wait
  done
}

Data of Wheel 1+2

Code: Select all

itape1="0x3C 0x5A 0x81 0xC3 0xC3 0x81 0x5A 0x3C"
itape2="0x3C 0x66 0xE7 0x81 0x81 0xE7 0x66 0x3C"

The first Wheel (itape1) is calculated out of...

I also saw an example of a slide, where the image is shifted to the right, very cool!

Follow the link, see what you think of the work, it is not complete but the main one is there!

The i2c2oled NCC1701 Demo?
That's Display based pixel scrolling.

//Edit
Nice Pictures, well done.
But you now that you need to convert them to B/W and pix format?
See https://github.com/venice1200/MiSTer_i2 ... dification

...and renamed to the Cores name.

Posted: **Thu Dec 09, 2021 5:43 pm**

I don't know much about this project, but do you want an extra column on the tty2oled to track images created for this, or does it work differently?

Posted: **Thu Dec 09, 2021 7:11 pm**

That's right "Venice" I haven't converted to .pix yet, but this is easy I've already tested it here, now like you said I have to rename it to the name of each "CORE" for display!

Ps.: I ended up selling my Mister for a very good price, and the other one I bought arrives next week, so that's where I can really test it out!

Ps. do you use some .pix as right scroll? if you use it, can you make a video for me to see?

Hardware Scrolling means for SSD1306 Oled, define the display area which should scroll and start scrolling.
It will continuously scroll until you stop it.

I am not sure, we will see.
Thanks for asking.

Posted: **Thu Dec 09, 2021 7:43 pm**

Simply wonderful, mine is this SSD1306, I'm Noob, if you can I'd like you to teach me how to do it, I don't know anything about the command line! hahaha!

Teach? What exactly?

Posted: **Fri Dec 10, 2021 4:51 pm**

I am adding in support to view the i2c2oled pix files in the tty2oled pixviewer

@venice opened a PR in i2c2oled repo to add a workflow to generate the data file

Screenshot 2021-12-10 085022.png

Posted: **Fri Dec 10, 2021 6:33 pm**

I am thinking about moving the i2c2oled pictures to the picture repository.
Would this help or make things easier?

//Edit
Idea dropped!

Posted: **Sat Dec 11, 2021 2:12 am**

Yes Venice, it would be perfect to move the images, accordingly! ^_^

Ps. Just amazing the .pix viewer on the site!

Jump to https://venice1200.github.io/MiSTer_tty2oled_Pictures

Many many thanks for this update!

Is there somewhere to download all the full .pix "128x64" of Arcade games?

Posted: **Sun Dec 19, 2021 9:29 am**

Not that I know.

But you already made a lot of nice looking png’s.
They just need to be converted and renamed.
Could you do this?

Posted: **Sun Dec 19, 2021 11:21 am**

Friend "Venice" follow the link, I've already renamed, add more cores it and converted it to "pix" see if they're ok"
