upload trough webserver not working

[hakmes]

Dear developer,

I've been experimenting with your code to build my own pixel frame with 12x12 pixels.
I have most of it working. I can show gif's when uploaded trough arduino IDE SPIFFS and show the clock (although the time is wrong) and text. I am not able to use the file editer/uploader. As soon as I click the link my Wemos D1 Mini freezes and reboots.
Any idea what I am doing wrong?

so far I love this project! But if I could upload new gif's trough the browser it would be perfect 👍

ps. took me a while to notice that I had to connect RX as datapin instead of the usual D4 pin.

I made a hat with a pixel display last week. I had to update some of the code and libraries. Let me see if I can get some changes in.

[alanswx]

I think the classes subclasses from the web library need to implement another method.

Isrequesthandlertrivial - needs to return false. I will try to check in the fix tomorrow. It will fix the piskel code too I think.

[alanswx]

This should work now. Let me know.

[hakmes]

wow, never had this quick support 👍

Browsing files now work, but I get error 500 when trying to upload a gif and error 400 when I click create. And for some reason now all text is mirrored on my pixel frame. Clock and IP adress scroll mirrored aswell.

typedef ColumnMajorAlternating90Layout MyPanelLayout;
//typedef RowMajor90Layout MyPanelLayout;

I changed these 2 over, but that didn't help. Now everything is unreadable haha.
What does this do? is it related to the the wiring of the leds?

gtg to work now. would have wanted to investigate more.

-edit-
RowMajorAlternatingLayout did the trick

you can drop some gifs in the data folder and reupload the spiffs. Let me know what is working and what isn't when you are done. What size SPIFFS do you have? It needs to be bigger than 1M.

[hakmes]

I've set it to 3M SPIFFS.
I've made some screenshots. Maybe that helps.
I login to the edit interface with admin/admin.

I uploaded the async web sample spiffs data and it worked. I need to figure out what the differences are. I think I may have checked in the wrong version of the code. That is why the pixel orientation was wrong. I will try to spend some more time on it Monday or Tuesday.

[alanswx]

Give it another try. I was able to get everything working on my esp8266 setup. I got it to compile it on esp32, but i haven't tried it on my esp32 board yet.

[hakmes]

Yes! uploading files and deleting them works on my Wemos D1!
Many thanks!

Did you try the piskel editor? It is pretty cool. You can use it to make your own animations and save them on the device. Then download them as gifs so you can keep a copy if you blow away the spiffs. I should upload some more gifs

[hakmes]

The piskel editor saving mechanism works, but live display is going wrong in my case.

When I create this
it will show a different pattern. The part on the right is reminiscence of the clock display. (see issue below)
I guess this is because I am using a 12x12 grid instead of 8x8. Even though I've changed the default size to 12x12 in piskel. It seems that the livepixeldisplay is forced to use 8x8?

The other thing I noticed that when switching from a gif back to clock or text, some parts stay into memory.. Is it possible to send a black command or something before starting the clock or text box?

[alanswx]

Something is probably hard coded to
8x8. I should figure out a way to put a setting or a define in.

Where did you buy the 12x12?

[hakmes]

I didn't buy a 12x12 grid. I made it myself.
I used a pressed board with in total 144 WS2812 LED's from a strip that are routed from left to right, right to left, etc. Then I soldered all LED connections (The grid was bigger than the default size of the LED strip) and covered the LED's with a grid designed for air intake in buildings. Then I've put a piece of paper on top to diffuse the light.

In my first attempt I routed all LED's from left to right and connected them with wire on the back of the board. But after taking a closer look at the instructables page I noticed it was different, so I changed all the wiring. I don't know if this could have been avoided by changing the layout in the code. But it was too late before I figured out that you could change that.
This is my grid. before I changed the direction of the LED's. So in this photo everything is from left to right.
