Need to pay attention to shared grounds for R and L phones. The amp is a balanced output without a ground reference. So mono should work. Stereo would be an issue and not likely.

Exactly, should just be able to put a TRS on it and plug in some headphones np. a good question though.
haughty quiver
yes, naturally derived dog, not machine learning ๐
sand lotus
i think 1w might be a little low though, generally the 3w would be good for headphones and just turn down the gain.
austere pollen
The MAX amp can do slightly more than 3W
inner spade
Exactly, should just be able to put a TRS on it and plug in some headphones np. ...
Mono yes, stereo no because of the headphone elementsโ shared ground.
sand lotus
yeah it's a 3W amp, not sure why JP said 1W.
inner spade
yeah it's a 3W amp, not sure why JP said 1W.
Itโs 3w for a 4-ohm speaker and closer to 1w for 8-ohm speakers.
sand lotus
that will definitely drive some headphones loud enough where you'll have to limit the gain.
ahh
if it's split for headphones then will do 1.5W per headphone speaker at 4 ohms.
unless mono... derp
austere pollen
is meant for plugging in a 4-8ฮฉ, 3W-or-less speaker
I think the guide is kinda misleading there. Or I don't understand something correctly.
First of, I'm using this amp with an 8W speaker and it's great! Just not enough bass so I have some larger speakers on order that I want to try. They're 30W.
I think it works this way:
Speakers are rated for more W than the Amp = no problem. Speakers just aren't as loud as they could be.
Speakers are rated for less W than the Amp = you could damage the speakers if you blast them at full volume.
3W with a single 4 Ohm speaker is already way too loud for me at full volume ๐
inner spade
The output wattage of this amp drops inversely with speaker impedance. Headphones of 100- ohm or greater would be loud but nowhere close to 3w.
sand lotus
I'm using adafruit's 20W amp with 2x 40w speakers. You'll want more juice to drive the bigger speakers.
austere pollen
Itโs 3w for a 4-ohm speaker and closer to 1w for 8-ohm speakers.
also depends on the input voltage of the amp
and how little THD+N you want
(there, the lowest line is 3,7V the others are 5V I think)
sand lotus
3W isn't enough to drive a mail boombox
needs moar
20W amp good
you could in theory hook it up to headphones... if you don't mind bleeding ears and ruptured eardrums.
the 3W amps are good for the smaller speakers and headphones. typically they max out at 3W specifically to avoid hearing loss. it's an industry thing.

I'm not familiar with it, but the shields in Dune only allow slowly moving objects to pass, making projectile weapons obsolete. I believe the universe explanation is that the shields are tuned that way in order to allow air to pass through.

Lady Ada and Phil, just wanted to say thank you for your willingness to be up front about not only what you do, but how you do it. It's rare to hear the level of honesty from a business owner when they say to their customers "We're not the place to buy one piece, if you need just one thing, go to DigiKey." That says so much about your personal and business ethics, and it's just one more reason why I go out of my way to support Adafruit every way I can. You make it possible for n00bs to "get in without getting overwhelmed", and that is something truly special. โค๏ธ

It is a good start (and test) before plugging an unknown origin USB device/key in your computer.

So I wonder if by doing deep dive on other topic in the past, this attracted the python side of the community to try the code early (and report bugs) and the core/C side of the community to contribute or look at the "kernel" code. By other topic it could be pico support, or PIO usage or ...
Like for other development showed here, the fact that it is explained and demonstrated, we know the direction, we know what already works and it bring interest.

This is true. First time I ever heard of PIO was Scott's early peak at the Pico like 2 years ago. He was quite excited about the state machines.

I heard some recent ideas of using a second core for displayio. Is there any vision how this would work? Do we need some concepts around animation of shapes that you could setup their trajectory and timing in CP but the core C-code would handle all the animation?

So second core is used for HDMI, is it also used for USB Host?

I know that the displayio core code has a lot of checking for dirty rectangles and then updating the display.

interested why you're trying smaller bit files instead of sticking with indexed 8 bit?

SRGB is really for print shops, less for web work.
Sorry, but this is Very, Very Wrongโข. Print shops use CMYK color spaces and use color matching systems like Pantone.

sand lotus
It's color representation on a monitor for printing. "Hey it's showing red on my screen but printing more like magenta"...
Not all print shops use pantone, they spend money on very expensive monitors that produce the actual colors on the monitor that will be printed in that color... which used to exist with CRT's but not so much with LCD's.

I think transparency might be a new feature in the linux kernel ;), also reminded of this:

I think you hinted in a New Products video that you might possibly have a SEN55 breakout coming. Is that the case/is there even a super vague ETA on it? Iโve got one with your boost board stuck on top and a gnarly tangle of jumper wires that works in CP via @unreal bay's library port, but itโd be nice to get another one thatโs less of a mess.
open girder
we don't have one designed yet! we just got the cable and have been trying to get some other big projects out the door

FWIW, your boost board fits on top of it pretty well, though not sure if hot gluing things is really Adafruit's style, and the 6 pin connector where you have to ground one of them and not use one of the others, is a pain. Keep being tempted to buy a crimping tool to make it neater (cropped out most of the mess here).

Hey everyone! Iโm looking for some advice on the Disney Magic Band Reader. I followed the tutorial and got one assembly pretty much all together. Unfortunately when scanning something, it doesnโt light up the LEDs and plays an awful sound thatโs definitely not one of the files on the program. I have a feeling the feather didnโt program/code properly and I tried it multiple times but it is still doing the same thing. Has anyone had this issue for those who have done the magic hand reader tutorial?

MicroPython have stopped on IDF 5.02 as they have lots of BLE issues on 5.1 at the moment.
4.4->5.0 is a big change- 5.0->5.1 is a simpler challenge I think. MP is all on 5.02 now, but there are PSRAM issues where PSRAM only uses half the amount available.

for weather if it triggers a keyerror i'll just do a continue which resets the wifi connection, and attempts to reconnect forever. i only update once every 15 minutes so if it fails i only really lose 15 minutes of data vs a hard crash until i notice it's crashed... which could be overnight and down for hours. it's the lesser of two evils.

Will there be some methodology in retesting everything? Or do we just wait for issues?
I will be using main as always, so expect to me to find a few at least.
sand lotus
pushing releases and waiting for issues is normal. we'll get bug reports and the beta testers will jump on testing issues.
8.0 was really really buggy and an important part of smoothing it out is all the testing reports.
devs can't test for every single board, the fact that one release works on hundreds of boards still blows my mind.

good morning โ
convert png to 8-bit indexed bmp sprite sheet?
In a lot of those types of sprite sheets I've noticed everything isn't in a perfect grid but doesn't tile grid require splitting every tile exactly the same. Wondered how to work with that.
I mean on the spritesheets that people make available on that site, and sites like it. Many of them are not in perfect grids. Would you have to crop each one and resize or copy/paste so they fit into a perfect grid?
like this, they're not in a perfect grid
right this is a bad example because most of them are doubled, but you know what i mean.
I figured it would be something like that with an xy file but tilegrid doesn't work like that to my knowledge?
It would be more intensive on the MCU instead of a perfect tilegrid which is why I've avoided doing it that way. A perfect grid is just easier to work with regardless if it's circuit python tilegrid or on any platform (my opinion).
For a practical real world use of tilegrid I use it for battery gauge level sprites. I've seen other weather projects using single icons instead of sprite sheets for clouds, rain, etc.. I think sprite sheets are more efficient than popping/removing individual icons.
Loading multiple icons vs 1 sprite sheet. The sprite sheet from my experience just loads faster because it's always in ram. I usually work with the S3 which has tons of ram now because I found the Samd's just don't quite have enough ram to do all the graphics. It's possible sure but the S3 is blazing faster in comparison.

oooo, that sounds like a perfect place to demo the rpi's 2d core
sand lotus

dry shore

in the case of the rpi's 2d core, there is no need to align sprites to a grid
you just give the hardware the address of the 1st pixel in the sprite
and the byte offset, to the next row in that sprite (the width of the atlas, times the bytes per pixel)
sand lotus
could do that sure, i'd rather brute force it with gobs of cpu & ram with an S3.
only because i'm not good at optimizing for the rp2040 or samd.
sand lotus
right but those are precompiled with the pico dvi?
dry shore
for 13 sprites, you only have to write 372 bytes to MMIO per frame
this is on the broadcom SoC, pi0-pi3 family
sand lotus
ah well the raspberry pi is in a completely different world of power
dry shore
yeah, the 2d core can fully accelerate this type of rendering
for each sprite, you just define the source addr, stride, src w/h, dest w/h, and pixel format
and it supports a range of pixel formats, rgb332, rgba4444, rgb888, rgba8888, palette (1/2/4/8 bits per pixel), and more
sand lotus
i could see that being possible on a Pi3/4 with blinka layer and circuit python. you have a lot more computing power available to you with DDR if i'm not mistaken.
i mean you can use a pi3 as a media center to watch movies.
dry shore
in palette mode, it also allows alpha to be in the palette colors
in this case, its a 1 bit per pixel palette, where 0 is transparent, and 1 is solid white
the r/g/b fades in the background are just another sprite, that isnt animating
sand lotus
that's clever
dry shore
in this demo, i was just streaming a 1bpp video file, from usb to ram, and page-flipping on vsync
sand lotus
people have been trying to do bad moon and doom in circuit python for a while and the hardware just isn't up to the task. the iMX might be the first microcontroller to legitimately do it with circuit python but it doesn't have much ram.
sand lotus
it's been done with C and Arduino because it's precompiled but circuit python struggles a little
sand lotus
well... i also have baremetal 3d drivers
that would help yes
dry shore
with that, you just need to define a list of polygons, and then the hw does the rest
and if minecraft (java) can get good 3d rendering, then i cant see too much reason why (circuit)python cant do the same
sand lotus
that's waaay over my capabilities. very impressive though.
well, can you play minecraft on circuit python? not really. java has the luxury of usually running on a PC or SBC with a fast CPU and DDR.
dry shore
its fairly simple:
https://github.com/librerpi/lk-overlay/blob/master/platform/bcm28xx/v3d/v3d.c#L349-L356
addshort(&p, x << 4); // X in 12.4 fixed point
addshort(&p, y << 4); // Y in 12.4 fixed point
addfloat(&p, 1.0f); // Z
addfloat(&p, 1.0f); // 1/W
addfloat(&p, 1.0f); // Varying 0 (Red)
addfloat(&p, 0.0f); // Varying 1 (Green)
addfloat(&p, 0.0f); // Varying 2 (Blue)
for each corner of each polygon, you create a data structure like this (can also just be done with an array of plain c struct's)
state.primitiveList = malloc(3);
state.primitiveList[0] = 0;
state.primitiveList[1] = 1;
state.primitiveList[2] = 2;
then to make a triangle, you define a set of 3 indexes, into the list of points
if you want 2 triangles, then define 6 indexes, and add more points to the first list
sand lotus
yeah it's the C to Python to Micropython to Circuit Python interpreted downstream that kinda slows things down, and doesn't have the power of a pi or PC behind it.
i could see it being possible on a Pi with blinka and circuit python... not a microcontroller quite just yet.
dry shore
yeah, the tricky part, will be generating these 2 arrays, at 30fps
sand lotus
The stuff they're doing with DVI/HDMI on the Pi Pico has shown it is possible in little spurts as a demo but just not enough ram buffer to do longer stretches of video. If you could figure out a way to provide an RP2040 with tons of external ram then it would open the door to more possibilities.
dry shore
yeah, thats where the pi3 has it easy, you just have 1gig of ram from the start
sand lotus
yeah or up to 8GB in some cases and it's not just QSPI ram it's DDR.
dry shore
and surprisingly, the usb interface is fast enough to read a frame of video, in under 1/60th of a second, so i can do raw video playback with zero read-ahead
sand lotus
and the Pi probably supports USB 3 but circuit python is limited to USB 2.0 full currently i think.
sand lotus
though i don't think that would matter if the display is using DVI
dry shore
LS usb1 1.5 Mbps
FS usb1.1 12 Mbps
HS usb2 480 Mbps
SS usb3 5 Gbps
SS usb3.1 10 Gbps
oh didn't know it was as simple as that. good info.
dry shore
the rp2040 is only capable of LS and FS
sand lotus
so either circuit python defaults to FS and they're working on HS or it defaults to HS and they're working on SS... I can't remember.
dry shore
the broadcom SoC's in the entire rpi lineup, can do LS/FS/HS
the pi4(00) is special, in that it also has a pcie bus
and a pcie<->usb3 chip on board
sand lotus
what the chip can do vs what circuit python can do are not mutually exclusive.
dry shore
yeah
i recently write usb drivers for the dwc2 found in the whole pi0-pi4 lineup
but my drivers lack split transaction support
sand lotus
whaat, that's awesome.
dry shore
so if you drive the 1st hub at high-speed, your limited to high-speed only devices
which means no keyboard/mouse
ive not tested it, but i believe i can disable HS support, and just drive the hub at FS
at the cost of crippling performance, i would easily gain mouse/keyboard support
sand lotus
i think that might be part of why they're working on the next USB speed upwards, for mouse + kb support which is ambitious for circuit python on a microcontroller in itself. they're working on cursor implementations.
which for a pi 3 is built in and just part of the OS, doing that for a microcontroller is a bit more challenging. perhaps that's part of the draw for some people towards microcontrollers, there's a lot to pioneer, implement, and is a harder challenge due to all the abstraction layers.
dry shore
well, thats where my fun starts
i'm doing all of this without linux
and the kernel i'm using as a base, had no usb, 2d accel, or 3d accel code
sand lotus
map structures? since they're part of the map but also dynamically different per map?
sand lotus
i'm doing all of this without linux
ohh ok, yeah good luck with that. way over my skill level. ๐
dry shore
its not that bad
https://github.com/librerpi/lk-overlay/blob/master/platform/bcm28xx/hvs/hvs.c
void hvs_regen_noscale_noviewport_noalpha(hvs_layer *l) {
assert(l->dlist_length == 7);
assert(l->premade_dlist);
uint32_t *d = l->premade_dlist;
// CTL0
d[0] = CONTROL_VALID
| CONTROL_PIXEL_ORDER(HVS_PIXEL_ORDER_ABGR)
| CONTROL_UNITY
| CONTROL_FORMAT(gfx_to_hvs_pixel_format(l->fb->format))
| CONTROL_WORDS(7);
// POS0
d[1] = POS0_X(l->x) | POS0_Y(l->y) | POS0_ALPHA(0xff);
// POS2, input size
d[2] = POS2_H(l->fb->height) | POS2_W(l->fb->width) | (l->alpha_mode << 30); // fixed alpha
// POS3, context
d[3] = 0xDEADBEEF;
// PTR0
d[4] = (uint32_t)l->fb->ptr | 0xc0000000;
// context 0
d[5] = 0xDEADBEEF;
// pitch 0
d[6] = l->fb->stride * l->fb->pixelsize;
}
this is the code behind drawing sprites
d[0] declares that this is a valid entry, the pixels are in ABGR order, there is no scaling, what pixel format its using, and that this sprite is 7 slots long
