Animations on a TFT screen. Mission Complete

Projects Showcase
1

I visit this forum quite a lot, normally lurking from the shadows. However I never really offer anything, I just take guidance from everyone else. Well on this occasion, I'd like to show what I have achieved from reading the advice of the people on this forum. So for a change, I'm not asking :slight_smile:

I previously made two Ghostbusters Reboot proton Packs with an Arduino Uno controlling Neopixels, LED's and lights and sounds and stuff:

Reboot Proton Packs

It was a huge learning curve.

I decided I wanted to make a version 2 proton pack. But I also wanted it to have a small screen displaying basic animations. I tried loads of different TFT screens, and all of them were FAR to slow to make an animation.

Well thanks to the ILI9341 and the accompanying library by Marek Buriak, I was finally able to get raw 565 images to load at just over 4fps. Which was sufficient for very basic animations.

I'm still only using his half speed SPI, so I know I can squeeze a bit more power out of it, if I can get it to use FULL speed SPI. On jumpers, that's just not possible though.

Anyway, here's the footage...

Very cool! 8) Well done! :slight_smile:

But.... sorry to burst your bubble, I had 'video' 320x240 resolution running at 5.71 fps 2 years ago :wink:

I haven't actually bothered putting it to the test but theoretically I should now be able to achieve about 12.5fps since I have screen draw speeds as low as 78ms now for a resolution of 320x240 :wink:

Woah, how did you manage this? Can you share the code? And the setup? I'd love to get more speed out of it. I'm even considering moving to a teensy.

Nice work! Would you mind if I link your video in my 'Demos' section in ILI9341_due docs?

@Graham: I presume that screen uses 16bit interface, right?

That would be awesome. You can embed me on your tutorial page as well if ya like? :slight_smile:

Traffic is goooood :slight_smile:

@marek , yes 16 bit.

@magic, will have to see if I still have the sketch.

So I been doing some tweaking (and cheating :wink: :P). How upset would you be if I got 20.09FPS for 320x180?? 8)

Proof to follow soon..........

The 'cheating' is using SPI flash not SD as source, hence I only have 132 frames for the whole video sequence :frowning: but never the less, it is impressive to see!! :wink:

I am REALLY looking forward to receiving my Teensy 3.6 and 3.5 very soon :slight_smile:

You are a God among mere mortals haha.

Are you gonna release the sorcery?

Nice job.

This is also with an Arduino Due? I bought one ages ago and have literally only done a 'hello world' test via serial to confirm it works.

Might have to whip it out again as I have a few SPI flash chips lying around.

@pyro,

Yes it is using a DUE. Can't wait to see what the Teensy can do! :slight_smile:

@magic, There is no sorcery, it is using my UTFT_GHL library which used SPI Flash as source instead of SD Card, it makes a fair bit of difference!

Since my last message and disappointingly short video clip, I have been working on my library to make it possible to combine multiple Flash IC to be seen as one large one, I now have a 314 frame video clip which runs at 18.6
FPS, it is a little slower as a result of the voodoo which makes the 3 Flash chips appear as 1....

314 frames drawn in 16861.38ms =18.62 FPS
314 frames drawn in 16861.27ms =18.62 FPS
314 frames drawn in 16861.23ms =18.62 FPS
314 frames drawn in 16861.35ms =18.62 FPS
314 frames drawn in 16861.19ms =18.62 FPS

314 frames drawn in 16861.25ms =18.62 FPS
314 frames drawn in 16861.22ms =18.62 FPS
314 frames drawn in 16861.28ms =18.62 FPS
314 frames drawn in 16861.29ms =18.62 FPS

Still, not too shabby :smiley:

Edit, I now have 424 frames which runs even slower :frowning: at 16FPS, clip shown here Arduino DUE - 'video' 424 Frames at 16FPS - YouTube

I know this is pretty old, but did the code for this stuff ever appear?
