i can hear the square, saw, and sine waves now. i love the way a good square wave sounds.

[inner spade]

Yeah. Designing, prototyping, adjusting for a month.

[teal river]

I just love everything about that design — the spacing, layout, color…

[sand lotus]

how true to color will the soldermask be? that's a really nice purple.

i think liz had a project where she used a bigger party parrot.

[inner spade]

The default OSH Park mask is quite a bit darker than the rendering. I made it more transparent to help inspect traces and fills.

@sand lotus The Cowbell sequencer design is a hallmark of form and function. Watching it evolve has been fascinating.

[sand lotus]

https://cdn-learn.adafruit.com/guides/cropped_images/000/003/693/medium640mp4/heroGif.mp4?1667423361

wasn't as big as i thought and has a black background, which is kinda cheaty but smart.

[teal river]

Cow

[sand lotus]

progress! 🙌

that's super fast! sweeeeet!

try make_opaque instead?

hmm goal might be to get true transparency though, that would be nice.

could you flip flop between frames for make_transparent to make_opaque perhaps?

[inner spade]

I’m confused about how to use ColorConverter. Is it a static or dynamic filter pipe? What are its inputs and outputs? When does it have to be used and when not?

How does it supplant or supplement a palette?

[sand lotus]

imagine ram is going to be pretty important for the ability to use animated gifs. the s2 and s3 will obviously perform better but still important to get it working with M4 and M0's if possible too.

i'm think M0's importance for CPE for education and getting kids excited in electronics. they love animated gifs. we live in the era of memes.

[smoky island]

does this play?

[sand lotus]

as a video yes

[smoky island]

@nova totem any ideas about the way it's showing the other frames in the background, or the way the left side is teal? (recording just above here)

I tried it on pico_system so I could stay in rp2040 family to start with. It loaded up and displays, but has this stacking thing going on.

[sand lotus]

the simpsons one he was using didn't have any transparency

https://tenor.com/view/the-simpsons-homer-simpson-good-bye-bye-no-gif-5173989

Just use bucket fill with black on each transparent section around the parrot each frame.

Each frame is transparent so you'd have to edit each frame. Might just be easier to find an animated gif without transparent frames.

[nova totem]

I'm home now (zoo trip with my nephew) but there could be something with transparency acting weird

It is supposed to handle transparency but I wonder if there is some case I am missing in the draw function

If you want what size display are you using? I can send you the GIFs I had for testing

[sand lotus]

Use EZgif for quick conversions.

I use that for BMP sprite layout creation too. great tool.

pretty sure you should be ticking "as animation" or it might only export a single frame?

[nova totem]

Also can you send me the GIF that isn't working? I can try it out later too

Color converter (also an option I have to add to change how it changes)

THey're probably 565 but BE vs LE

[sand lotus]

might be able to speed it up by reducing the milliseconds delay parameter during file save?

[smoky island]

this is the first one I tried. I'm tinkering some with a homer one in gimp as well, still changing things on it

[nova totem]

cc = displayio.ColorConverter(input_colorspace=displayio.Colorspace.RGB565_SWAPPED)

[sand lotus]

when saving your animated gif in GIMP there's a parameter for milliseconds delay below "animated gif" tick box.

[nova totem]

Try that (the _SWAPPED)

It won't render it faster (unless you are reading the delay and pausing - I never did)

The code won't pause between frames unless you tell it to

[sand lotus]

Yes I usually get 3 fps for bmp sprites full size too yes.

Ah I see it's because the parrot was much smaller it improved the fps.

[nova totem]

Oh I have an idea what may be up with the parrot gif

[sand lotus]

It also has transparency so it didn't have to redraw the full background?

[nova totem]

I think it is always drawing at Y=0 and the changes happen lower down

Yeah something with that I'll have to look at what the draw function is getting i'm probably missing something

I saw it on another GIF that I had from ages ago but I didn't look into it

Yup I do not process the upper left corner parameters - oops

Yes scale slows it down

[sand lotus]

faster parrot = harder party

[nova totem]

also the delay is saying 40ms, and at 40fps each frame is taking 25ms, so technically you should delay 15ms

also the play_frame function returns the delay to the next frame

sorta:

start = time.monotonic()
delay = gif.play_frame()
display.refresh()
time_taken = time.monotonic()-start
time.sleep(delay-time_taken)

[sand lotus]

https://www.gimp.org/tutorials/Simple_Animations/

Just double-click the layer comment in the layers' window and a delay in ms enclosed in brackets ()

[nova totem]

Thanks for the parrot GIF, going to have to think just to make sure I get missed parameters added in properly.

Yeah could have play_frame that checks the delay, but could have a play_frame(override_time=True)

On Espressif you will need that pragma line I pasted earlier - I think

Or just comment out that one line because it isn't actually called (and I may trim the library down some for CP still)

it is not in gifio yet

(moving there it is in displayio now) the gif.c is in /lib/AnimatedGIF

very start

line 1

should be okay there - i think

it says ignore that warning for that file. A bad idea generally. That will not be the long term fix

I'm guessing so. Didn't dig too deep

CPU is faster 240Mhz i think?

[sand lotus]

S2 is 240mhz single core. I've also noticed the S3 dual core does slightly better than S2 as well.

CPU definitely matters

[inner spade]

Amazing progress @nova totem .

[nova totem]

Thanks, this is helping a lot to catch those weird things I didn't think of and see

Haha okay party parrot is in line but not quite right yet

[inner spade]

So nice to have extra eyes on projects.

[nova totem]

I'll post a video up in a moment

[inner spade]

Parallel display on PyPortal

[nova totem]

ha sorry didn't mute volume on the video

[sand lotus]

seems like some artifacts coming in from the left side?

pico pio vs esp32-s2 for animated gifs is the question of the year

state machine vs brute force speed basically

https://tenor.com/view/same-same-but-different-the-interview-james-franco-gif-14031071

[nova totem]

Changing the delay won't speed it up, unless you are delaying yourself as it isn't automatic

[sand lotus]

if you have a 100 frame gif there's no way you're going to edit each frame parameter, there's gotta be a better way.

the simpson one is about twice the size of the parrot, if you make it smaller bet it would play smoother too. i'm ok with size limitations vs fps. can definitely work with that.

it's a very promising start! thank you Gamblor!

thank you for the stream foamyguy. awesome stuff today.

hiiiii

BabyAda is best assistant

Ohhh, I need this...

[viral sail]

Good evening.

[inner spade]

From an episode of the Adalorian.

[unkempt shoal]

I have a BME688 but it always seems to show 10 degrees too warm vs my wall thermostat. Any way to recalibrate it?

[sand lotus]

super bowl is still like 30 mins from being over. I forgot there's a 30 min halftime show only for the super bowl.

[teal river]

Question -- @gentle jacinth wishes to know, LadyAda, what's your favorite microcontroller board?

[teal river]

Oopsie!

"Not the cool we were looking for, but cool nonetheless"

[upper sandal]

it was a question on the forum

[teal river]

The streaming software is having a mental breakdown XD

[viral sail]

Where in the world is LadyAda's desktop?

[sand lotus]

ohh i like that backdrop, very cool

[upper sandal]

someone on the forums was asking about an adapter to use feather wings with the QT PY, and I was thinking that it could take the form of a feather doubler or tripler, with a QT PY slot connecting it to the I2C, SPI, UART, and some of the pins (maybe with jumpers to select some alternatives)

[waxen fulcrum]

Any watching the Super Bowl

[teal river]

Someone else mentioned preferring the S2 over S3 due to stability issues on the S3

[sand lotus]

I'll delete my question in favor of Neradoc's, he knows more about that question than i do.

[upper sandal]

yeah the S2 is still better supported in CP too

although it's more about little issues now I guess like I2C

[sand lotus]

i2s BFF <3, i want one

[teal river]

https://tenor.com/view/galaxy-quest-never-never-give-up-gif-4398729

[sand lotus]

i was actually going to post that one, beat me to it 🙂

[teal river]

OpenOffice

Cowbell! Hehe

[sand lotus]

i love the cowbell logo. are we allowed to use that in open source designs?

[open girder]

@sand lotus yep, drop me a note [e-mail] and we'll send details so it's all good

[teal river]

What's the difference between SPI and SDIO?

[teal river]

@gentle jacinth "I don't have a favorite favorite; I like a lot"

[grand tusk]

Street Chicken!

[teal river]

Is that the same connector as the PyGamer speaker?

Is it common for color options to be random? I've noticed many Adafruit products with JST connectors have a notice of "the connector color may vary"

Do not skimp on crimpers! It's worth spending $100 on a high quality set because it'll last you an eternity

[proven crow]

2 1/2 questions: What code editor does Ladyada use? Should I stick with KiCad or learn Eagle? I know Eagle is considered more "professional", but is it woth the cost/free plan limitations?

[upper sandal]

I found it a little hard to get JST PH 3-pins cables to use with STEMMA ports on boards like the Fun House (I mean plugs with pre-assembled cables, both male and female for extension for example)

[teal river]

I have successfully imported EAGLE to KiCAD so nice

In my experience there are very very few instances where there's only ONE way to do a thing...

Usually comes up in particle physics

[viral sail]

Thanks @open girder and good night. 🌗

[sand lotus]

You can import Eagle to EasyEDA too. Eagle is the standard. It doesn't matter what format it is as long as I can import it to some program to work with. I wouldn't have learned nearly as much as I have since joining here because I can actually look at the schematic.

[teal river]

Great show! And yes, computers get confused, lol

[desert ravine]

I work in the elevator industry I don't think there will ever be a open elevator firmware

[proven crow]

Awesome, thanks @open girder and good night!

[sand lotus]

Shot you an email PT. Thanks for the show. 🙂

[upper sandal]

[sand lotus]

and the super bowl just started the 4th quarter. i swear football games say 15 minutes a quarter but it's more like 45 minutes.

[teal river]

15 minutes of game clock, but there can be a minute between plays that take 10-20 seconds XD

Plus the half hour half-time show

[nimble mural]

I've got some of the flexypins from pimoroni and their breadboard adpaters for the qtpy on their way to try to make my own "doubler/tripler" for testing multiple board for a future project that would require a couple of boards to get it working properly. Trying to minimize having to solder pins or headers for testing various BFF boards face up.

Very realistic.

[sand lotus]

thanks for the stream, mqtt stuff is fun to play with. the webcam will be for the 3d printer running octoprint and mqtt. stuff you're working on today is directly related to that webcam housing print in a way. 🙂

lol yes it looks super real. upping my 3d game. 😛

either that or my iphone 5 camera is so old it could be confused for 3d :/

same, my printer is in a different room and there's always that thing in the back of your mind that they're possible fire hazards.

like i can't babysit a 24 hour print

hoping to figure out a way to get the camera to feed to a mobile device too, somehow maybe

[glass stag]

Ahh, here is the chat.

[teal river]

https://tenor.com/view/red-panda-flowers-cute-walk-greet-gif-22902144

Multiple???

Gasp

Question: could you have 3 of these drivers, each with 16x9 LEDs, one red, one green, one blue, and have them display an image together?

QT Py with one of those for a little text badge…

[sand lotus]

Plan on setting up some of these on my octoprint webcam as lights on my 3D printer. This will be perfect!

Got 8, going to play with some for text display instead of the 7-segment backpacks. They use the same I2C address range as the 7-segment backpacks too.

[drowsy inlet]

made me think of the 5x5 neopixel bff, but can it control the individual leds at the same level as this driver?

[sand lotus]

You can control individual LED's np MikeP

[teal river]

8-bit PWM for each LED

[sand lotus]

It's how he was able to get the heart to display.

[drowsy inlet]

sorry, i meant pwm on the 5x5

[sand lotus]

You can chain more with the PCA multiplexer.

[cinder wind]

yeah you can use multiple buses with the CircuitPython library

[teal river]

Ordered 3 controllers, 2 red and one blue panel :D

[teal river]

The 5x5 indeed allows individual control of each pixel

[sand lotus]

The PCA9548 was JP's product pick of the week December 6th. You can chain as many charlieplexed boards as you want with these. https://www.youtube.com/live/gWVxxrDE5S4?feature=share

[teal river]

3 parallels of 16x9 arrays of these controllers; red, green, blue in parallel LEDs. So you’d have a resolution of 256x81 pixels, 36864 LEDs per color, 110592 total

https://tenor.com/view/laugh-higurashi-maniac-crazy-anime-gif-5121331

Ah, yeah, single 3-channel controller would be easier instead of 3 1-channel controllers, lol

[sand lotus]

If you want a bigger RGB matrix go with a matrix panel and featherwing matrix driver yeah. These are good for lighting or scrolling text displays (with a couple of them) instead of the 7-segment or 14-segment backpacks.

[teal river]

Predication: both will run at lower brightness maybe

[sand lotus]

The PRO of these is that they're a small footprint, if you want a small scrolling display.

[cinder wind]

red LEDs turn on at a lower voltage than white, so I think it won't work

[teal river]

Yeah, not enough friction from contact, lol

[cinder wind]

maybe try two reds

but even then it's still a bad idea

diodes in parallel == always bad idea

[teal river]

It looked like the yellow flashed when you pulled it off!

[inner spade]

Red LEDs have a lower forward voltage.

[glass stag]

Sometimes bad ideas are the best ideas.

[teal river]

… it is? I parallel LEDs a lot

All the half off LED panels were in stock when I was ordering

[cinder wind]

parallel LEDs where each LED has their own current-limit resistor is great

[sand lotus]

Gotta be quick Kyoshii 😉

[teal river]

I fast as lightning

[wind spoke]

Where (or Who) is Charlie?

[teal river]

Could you use the controller to power super high power LEDs with an external power source?

For like, giant billboard

Good show!

[cinder wind]

Charlie Plex was the 3rd Neo in The Matrix

[drowsy inlet]

thx!

[grand tusk]

thanks JP

[haughty quiver]

@wind spoke Charles "Charlie" M. Allen

[sand lotus]

Been loading my cart up all week. I usually order during JP's product pick of the week and throw in some half off stuff at the same time. Because you can usually use the coupon code from ask an engineer at the same time... which this week is twobffs 😉

[haughty quiver]

https://en.wikipedia.org/wiki/Charlieplexing

[sand lotus]

Thanks JP, I'll definitely get some use out of the charlieplexed backpacks.

[teal river]

Wait, you can??? I thought the code would be off by now!

[sand lotus]

never hurts to try 😉

PT usually let's it slide for an entire week until the next ask an engineer 😉

[teal river]

I shall attempt this in the future when I’m planning a big order… I usually do BIG orders to get the free shipping and the discount code

[sand lotus]

When they were out on maternity leave I was using an ask an engineer discount code for an entire month 😉

[teal river]

We just can’t do it all the time… we don’t want to bankrupt them!

[sand lotus]

PT the real mvp. It really helps with allowing a regular schedule of shopping for a week then pulling the trigger during JP's product pick of the week.

[haughty quiver]

Lars may be paying a visit...

[sand lotus]

hahahaha it was my little secret

[waxen bough]

I want! But what would I use it for???

[sand lotus]

There's always a 10% off discount code available somewhere either from JP, 3D Hangouts, or Ask an Engineer. If one doesn't work go back through the youtube videos and try another. It's really a perk of regularly watching the livestreams. Basically free shipping if you order a lot and I do, so I need it every time.

Pick up a couple Rufus and use it as a text scrolling display. I plan on using it as a webcam light. The amount of light they produce alone could be useful.... circuit python powered headlamp perhaps?

[waxen bough]

blue and green are gone.

[sand lotus]

It's best to buy stuff at the beginning of the show if possible. They set aside a certain amount just for JP's show and if it's a good product they'll run out of stock fast.

[waxen bough]

Kudos to Adafruit for also discounting the led boards for the show!!!

Which actually probably wouldn't be that hard...

I've actually used real speak & spell samples in some of my songs. This needs to happen.

I'm sure speak & spell circuit bending has been done plenty before but not sure about a midi controller.

Might be interesting to look at some thin black organza, chiffon, or netting, maybe backed by your clear or smoky plastic, but perforated. That's what we used in this project a while back. https://github.com/oesterle/geekyjacket

Just in case, I found this about ATtiny816 vs ATtiny817:

• QFN 20-pin => 24-pin

[upbeat coral]

Theres MMBasic on the Raspberry Pi Pico, is Python next?

I saw they're all seesaw -- are there advantages for each chip? Or is it to make it so there are many choices in the event one or more goes out of stock?

[dim knot]

https://learn.adafruit.com/guides/latest

[strange mantle]

actually don't know full deets myself. but probably just tradeoffs. like the SAMD seesaws had SAM09, 10, etc. for different end uses.
theyll prolly say more during the new prod part of show 🙂

[slow spire]

Yep; Ladyada has been revising seesaw to use more available chips.

[teal river]

Options good!

[slow spire]

Not sure if you've watched Desk of Ladyada (usually on Sunday evenings), but she spends a lot of time there talking about specific chips in low supply, being retired, or part of the chip shortage, and work arounds.

[teal river]

Yeah, I know she's talked about a few current products having dual designs to work with two compatible chips or packages -- was just surprised to see several ATTiny seesaw boards come out at once

I use stacking headers to get female headers on microcontrollers. Just cut them to length. https://www.adafruit.com/product/5582

I'd probably try these, and carefully snip them. When I've done this before, I usually aim for having an extra pin, since the cut end may sacrifice a pin. https://www.adafruit.com/product/2940

What are the dimensions of the ATtiny breakout boards?

[teal river]

Question: I'm looking into creating boards and kits for the company I work for, and want to make it open source if they'll allow. What all is involved in creating open source licensing for products? And how do you separate the open source nature of it from the protected parts, like Adafruit has the Feather name, Adafruit logos and characters, etc., or are all those open source too?

[unkempt shoal]

I think Github has some good tips and comparisons between the different OSS licenses.

[sand lotus]

There's no learn guide for them yet so no dimensions which are usually in the schematics section of the learn guide.

Pro tip: When dimensions aren't shown, I count the header pin holes on the edge. There are 10 in 1 inch / 25.4 mm.

[alpine nova]

best use of desktop microscopes is by a twitch streamer called openset

[teal river]

I'm going to champion open source with my company because we can still profit on the hardware sales, but the community can benefit from the resources we generate, and we can benefit from community input

[alpine nova]

adafruit is best model for that

Good afternoon

[inner spade]

Testing the newest StringCar racer FeatherWing today. Being able to choose almost any MCU and Stemma sensor will make this a fun and flexible robot.

[lilac tusk]

Imagine using this

Lol

It’s an FPGA so probably much hard to use with but it would be interesting

A few generations younger than this: https://learn.adafruit.com/basic-string-car-racer/string-car-history

The switches detect end-of-string

Yes, to trick them out for speed, smarts, autonomy, and longevity.

… and esthetics like lights and sound.

If 4 is 0.04 then 100 is 1.00 (and that is one second).

If you want to see frames, you can put digit 1 2 3 4 ... 30 as images, generate the gif, then display, then film at high speed (like with an iPhone).

Orange is the new Black

That is called a green screen...

[ancient grotto]

make transparent is doing 0xFFFFFF

[wind spoke]

What is the index of green?

There might be 50 shades of Green... did you took the right one?

0xFF00 ?

[inner spade]

Index only works with palettes/lists, I think

The docs are confusing.

[inner spade]

Animated GIFs have multiple palettes; one “master” and one for each frame?

[wind spoke]

I guess they would share the pallet for saving???

https://webmasters.stackexchange.com/questions/304/can-i-have-an-animated-gif-with-more-than-256-colours-per-frame

[sand lotus]

good evening

[wind spoke]

Per frame local palette... that is the key information here.

Maybe "our" gif player has limitation and will fail on those tricky gif that try to break the limit?

From what I remember, GIF had a lot of trick possible, like text, partial update, ...

[nova totem]

Did you break it? 🙂

I used ColorConverter for this

Palette support would be nice but I hadn't built it yet

yeah if it is there its leftover

Surprised the build didn't throw a warning about unused reference

It's not in the dictionary

yeah that thing

[inner spade]

Default animated GIF format has a separate palette for each frame. Apparently there’s an extension to the standard for using a single global palette, but that’s not the default mode.

[nova totem]

I didn't look at how tilegrid/bitmap handles that

[inner spade]

Each frame has its own transparency list; not shared.

[nova totem]

That is part of TileGrid/Bitmap drawing as opposed to the GIF

I'll take a look, I'd think the bitmap color is accessible so should be able to see

[inner spade]

‘cept in CircuitPython, apparently

[nova totem]

The color in the bitmap is 0x0 like looking at gif.bitmap[0] it returns 0

What are you expecting to show through the transpancy? Do you have something behind it?

Where's the green come from?

Glad that works 🙂

look at gif.bitmap[0] should show the color

And I had thought a learn guide page(s) to show how to use it will be good. And as we (meaning me) see what its being used for or not can add features

[sand lotus]

https://tenor.com/view/parkour-cat-agile-look-at-me-go-zoomies-gif-17445063

[nova totem]

With the swapped colorspace (maybe I should make it so we don't have to swap it or have the parser configure it) it may have to be flipped but pure green probably

The actual RGB565 value

0x00ff00 is 24 bit. We need the 565 value

[sand lotus]

that makes sense

[wind spoke]

0b0000011111100000 ?

What if you remove the first frame?

[nova totem]

it can have colors not a palette. I don't think it is documented much

[wind spoke]

Black is 0 and was at position zero...

[nova totem]

0x07e0

[wind spoke]

^^^Try that

[sand lotus]

is green some kind of special color that's hardcoded somewhere else not to be transparent?

[noble grove]

Maybe it always does black and the number is the transparency.

[wind spoke]

Try 0x07e0 in the make transparent...

[nova totem]

A lot of this isn't in the gif itself

in the python code sorry

[noble grove]

try 1 and see whether it is still transparent

[nova totem]

So example for Bitmaps without a Palette:

bitmap = displayio.Bitmap(50,50,65535) 
# 50x50 with 65535 possible colors 16 bit
cc = displayio.ColorConverter(input_colorspace=displayio.Colorspace.RGB565)
tile = displayio.TileGrid(bitmap, pixel_shader=cc)

[strong acorn]

is it a new thing that YouTube stops streaming if I switch to a different browser tab?

[nova totem]

Also can you toss the GIF into discord I can try it out if you want

[strong acorn]

not logged in?

[wind spoke]

You need a rainbow as first frame, and see what color goes transparent depending on the value you provide...

[strong acorn]

it could be some weird internet glitch, had this happen last time too

[sand lotus]

yeah mobile requires youtube premium for that feature on mobile devices.

[strong acorn]

I'm on desktop, not logged in

[sand lotus]

works fine on desktop for me, on firefox

[strong acorn]

not logged in?

[sand lotus]

im logged in, maybe that's the difference?

[wind spoke]

I'll keep watching the recording. But that gif animation thing is really great addition to CP. I love it.

[nova totem]

Glad you do!

I think I gave you the wrong color with the byte swapping and stuff going on

Big/Small endian hurts my brain

Try this!

cc.make_transparent(0xe007)

The color is 0x07e0 but things are byte swapped... so 0xe007

[sand lotus]

[nova totem]

gif.bitmap[0]

[sand lotus]

the name is Gamblor, Mark Gamblor

[nova totem]

its not swapping within them I may have made a typo earlier copying things

Human view: 07 E0
Swapping E0 07

yes

That would work if you don't know your background color.

Something to think about is how the bitmap stores the color vs what humans see it as

[ancient grotto]

you can use struct.unpack

[sand lotus]

i honestly never use REPL but now I can see why it's so useful for thrown small ideas at it.

i only use it for debugging output

[nova totem]

Long story short: the gif parser reads the GIF (which has a palette) and converts it to RGB565 little endian. That is what gets stored in the bitmap object. Reading left->right as a human it seems backwards. But that is how displays read them.

We could parse the GIF into RGB565 big endian which reads more like a human left->right but the ColorConverter has to swap the bytes.

I did it this way with an eye on a future optimization to TileGrid and the converters. If we don't have to convert the color it saves time.

[sand lotus]

yeah go with the optimized state and we can adjust it later to be more human readable, agreed.

because right now we need every miniscule amount of optimization we can get for like 1 more fps

however at some point we're going to throw human readable conversion at some point..

[ancient grotto]

>>> data = b'\xE0\x07'
>>> import struct
>>> struct.unpack(">H", data)[0]
57351

[nova totem]

ColorConverter can be kinda slow. Maybe it can be optimized to (at the expense of size) but for common conversions. Right now everything goes input->RGB888->RGB565 (I believe)

[ancient grotto]

it returns a tuple that is why we use [0]

[sand lotus]

i would have never thought to throw struct at something like that

[ancient grotto]

🙂

[nova totem]

It needs to pass it to the colorconverter so not sure if it's ideal or not

[sand lotus]

yeah that one needs to be in the library for easy color conversions or at least something like that.

[nova totem]

Probably could expand ColorConverter

[sand lotus]

then later people could converter to RGB, HSV, HEX, etc..

having conversions from something to something would make everyone's lives easier.

[nova totem]

GIFs are palettes. I saved them as RGB565 as the library converts them for a display

[ancient grotto]

just FYI ..Fancyled library has some color conversions

[nova totem]

I have to take off now, but feel free to ping me later about any questions/thoughts/ideas.

[ancient grotto]

Thank you very much

[sand lotus]

Thanks @nova totem This is AWESOME stuff. Great work!

[nova totem]

Great! I'm open to adding/tweaking things after it goes live and people use it too

[sand lotus]

Coffee with Tim, see you tomorrow ☕

[inner spade]

Super work @nova totem ! Also thanks to @smoky island for taking us along on his walk through animated GIF country.

[smoky island]

Getting started for the morning now. I'm still in displayio land, but not looking at GIFs specifically today. Getting back to core arg validation PR and then some experimenting with ColorConverter. You can follow along on YT: https://www.youtube.com/watch?v=CkxPNoStjHg or Twitch: https://www.twitch.tv/foamyguy_twitch

[inner spade]

‘Morning. Looking forward to understanding more about ColorConverter but will be needing some ☕

[nova totem]

Good luck, may drop by later but have to go look at appliances right now 😦

[inner spade]

Yes 2 ** 16

(Counting zero as a color)

[inner spade]

565 fits in two memory bytes

[frank river]

as says @inner spade - RGB888 occupies 24 bits and RGB565 occupies 16 bits

some displays use RGB565 for storing colors like ST7789 - https://www.waveshare.com/w/upload/a/ae/ST7789_Datasheet.pdf page 82

[brazen chasm]

heya guys. Tim, whats going on today? 🇸🇪 👋

sounds interesting, as per usual

[inner spade]

So does ColorConverter just strip least significant bits when converting from 8 to 5 bits unless dithering is True?

[frank river]

RGB888 to RGB565

r_565 = (red_888 >> 3) & 0x1F
g_565 = (green_888 >> 2) & 0x3F
b_565 = (blue_888 >> 3) & 0x1F
rgb_565 = r_565 << 11 | g_565 << 5 | b_565

[inner spade]

The dithering produces a small amount of red occasionally when the 888 value for red is 0x07 or less?

Rather than just black

Fill an object with rgb888 value of 0x070000, ColorConverter will fill all black when dithering is False. With dithering True, would there be random red pixels?

Is the number of possible bitmap color values not compatible with rgb888?

[frank river]

Isn't ColorConverter designed to load images in different formats? It's mentioned with the function OnDiskBitmap.

Bitmap - This is pretty much what you expect, a 2D array of pixels. Each pixel contains an index into a "pixel shader", typically a Palette, which is where the actual color information comes from.

OnDiskBitmap - This creates a Bitmap image (picture) from a file stored on a disk, like omg_cute_kitteh.bmp. It must also be used in conjunction with a pixel shader, typically ColorConverter, to provide the color information.

Palette - This is a simple list of colors. A Bitmap's pixel value is an index into this list.

ColorConverter - Use to convert between color formats.

[nova totem]

Imagine the bitmap with actual RGB values in it and color converter changes them to the RGB values the display needs

pixel_shader i believe is a word for either Palette or ColorConverter (not sure if its a good word for it)

Bitmaps only support palettes or RGB values of 8/16/32 bits (and some modes less then 8 bits like black and white for ink)

e.g. bitmap = displayio.Bitmap(10,10,65535) means each pixel has 16 bits. Not a huge fan of that API myself (which leads to the issues checked for 32 bits and overflowing ints in C)

But you could (its broke it won't work) do: bitmap = displayio.Bitmap(10,10,4294836225) to make a Bitmap with each pixel have 32 bits. 24 bits would also ber useful to be supported.

Then it is just how those bits map to RGB values. 16 bits is usually RGB565. 32 bits would be RGB888 with the first 8 bits 0 (or alpha channel). 24 bits would be RGB888.

(It was broken before I don't think it ever worked)

ColorConverter then lets you take that pixel (be it 8/16/24/32 bits) in your bitmap and change it to RGB565 for a display. ColorConverter's output is hardcoded for RGB565

So say bitmap[0] = 0x00FF0000 (bright red 32 bits).
ColorConverter(input=RGB888) would change that into 0xF800 (RGB565)

cosmic rays? 🙂

That's... strange

[smoky island]

https://tenor.com/view/fox-mulder-xfiles-dana-scully-amazed-looking-up-gif-13935527

[nova totem]

What color were you trying to start?

>>> hex(cc.convert(0xff0000))
'0xf8'
>>> hex(cc.convert(0xff0000))
'0xf800'

I'm running KB2040 with my latest build. But that should return the same thing

I'm getting the opposite of you. Mostly the 0xf8 and rarely the 0xf800

https://tenor.com/view/cave-dive-darkness-leap-gif-5803442

To the C code!

[shell mason]

QCode?

[nova totem]

If you want we can find time and have a voice chat about it, may be easier to talk it through one day. (the bitmap/ColorConverter)

Extra fun... ColorConverter.c has not had a new commit in 2 years...

Oh the shared-bindings did

Last commit I see only changed the new object construction...

Printing shouldn't

ColorConverter seems slow in my testing - I think it's an area that could be improved for displayio speed

Only ColorConverter. I didn't test palettes (yet)

If it could be a timing issue try a quick sleep after each conversion

I ran 10,000 runs and got 4 wrong (without printing except if it didn't match)

[frank river]

it seems like conversion between RGB888 and RGB565

converter = displayio.ColorConverter(input_colorspace=displayio.Colorspace.RGB888)
for r in range(0, 255, 16):
    for g in range(0, 255, 16):
        for b in range(0, 255, 16):
            input_color = r << 16 | g << 8 | b
            rgb_convert = converter.convert(input_color)
            print(f"input: {input_color:#024b}, conv: {rgb_convert:#016b}")

[nova totem]

printf debugging the core now and the incorrect value is being returned from common_hal_displayio_colorconverter_convert

[frank river]

try it yourself - input: 0b111100001111000011110000, conv: 0b1001111011110111

[nova totem]

I think there may be something with an int vs uint in the core (could be wrong)

Okay see something

[frank river]

maybe different value is due to enabled dithering?

[nova totem]

colorspace->reverse_bytes_in_word if its not 0 you swap the bytes.

Not sure if it means anything but all the runs its set to 145.

But when its wrong it is set to 0

at 0 you don't swap the bytes which is what we are seeing

It looks like a rare memory overwrite error

Got it i think

In shared-bindings/ColorConverter.c line 76:

    _displayio_colorspace_t colorspace;
    colorspace.depth = 16;
    uint32_t output_color;

The colorspace depth is set to 16, that's cool, but the structure isn't initialized

and later we use colorspace->reverse_bytes_in_word

Which is random based on what memory the structure is placed in. C won't initialize it to 0 for you

Added: colorspace.reverse_bytes_in_word = true;

yup

It looks like that fixes it (maybe we should initialize the structure to 0 and then set it in case other values are ever used)

memset... i'l write it out in a moment

Zero errors now for me

memset(&colorspace, 0, sizeof(_displayio_colorspace_t));
That will blank the structure

Better yet that colorspace should be a constant. It is used on every call.

Like add it to the ColorConverter construct.

Also would allow it to easier change in the future to convert to arbitrary colorspaces

I'd put it in the displayio_colorconverter_t structure

we have input_colorspace just store output_colorspace

typedef struct displayio_colorconverter {
    mp_obj_base_t base;
    bool dither;
    uint8_t input_colorspace;
    uint32_t transparent_color;
} displayio_colorconverter_t;

The whole structure

_displayio_colorspace_t colorspace; And rename it ouput_colorspace

Yeah will do, or if I have a moment today/tomorrow I'll submit a PR to fix it

You still need the reverse_bytes_in_word to be true

You commented it out on line 77

That zeros it out. true will set it to 1.

It is consistent - but consistently wrong 🙂

yup

It is converting it to 565 little endian I think by default

Your bitmap bits look wrong. you have it set to 15 bits I think?

I think it is 65535

Yeah it works for me 65535 is a valid value

<Bitmap>```

Oh yeah 65536 I think

oh hmm

I think the reverse bytes swap should be false. Maybe... I may have made assumed it should be true because it had been, but in reality it should be false

[inner spade]

Is color converter converting twice, once when instantiated and again during .fill? Oh, I so don’t understand how the converter works.

[nova totem]

Yeah I will comment and test it more I need a break too myself

(and yeah that was the problem I built a version now it looks right - but haven't tested it besides the REPL)

[inner spade]

Thanks!
