[timid plover]

some of these font issues have probably already been solved, but it sounds like you are thinking about ways to pre-compute some of the optimized font files

[glad mortar]

fair 🙂

maybe this would be helpful though, they also do bitmap fonts internally
https://lvgl.io/tools/fontconverter

can output a c header or a binary

here their format spec: https://github.com/lvgl/lv_font_conv/blob/master/doc/font_spec.md

which I think mostly covers what you want?

[timid plover]

what are the issues that have you desiring to avoid lgvl ?

[glad mortar]

no no, not lvgl. Just the format they came up with.

the online tool then lets you drop in a ttf/otf font file and it generates a file according to that format spec for the desired font size

which might be handy for having users make their own fonts

fallback afaik only interesting for usage within lvgl

maybe the fallback field can't be empty?

haha ok

it is a nodejs script so can imagine its all local hehe

[unreal bay]

pretty sure it's an offline script too

[glad mortar]

huh with my test font it was instant

did you enable compression?

nice 🙂

[cunning cedar]

nice

[glad mortar]

interesting to me but it combines multiple of my niche interests haha

[timid plover]

it looked like there was an option to convert a range - like A-Z might be a way to explore the data structure for a known glyph

[glad mortar]

I think range only takes a hex range

[timid plover]

or does it want it in symbols

[still bane]

A while ago, I built a text rendering system that addresses many of the issues you've been talking about. It was for Xous on Precursor and written in Rust, so no direct reusability. But, it might be a useful source of ideas for alorithms and data structures.

One of the big things I did was write a code generation tool that makes all the sprite sheet and font file handling stuff into a pre-compile step that you can configure with json files. Output of that stage is generated glyph lookup code and integer arrays with packed data for the specific glyphs that you've configured to be included in your system. The system includes an index for the width of each glyph, so half-width, full-width, etc. are possible.

Glyph data and indexes live in XIP flash in their own partition. At runtime, the font rendering code looks up glyphs and blits to a frame buffer in RAM.

adafruit had a game type product - pygamer

[old surge]

👋

[timid plover]

cool -

[smoky island]

I think it may be 128x128. Maybe you scale the Group?

[timid plover]

aren't there 5 buttons on the fruit jam ?

get usb input work and use external pad

5 LED, 3 buttons

[nova totem]

I just came back to watch (late work before a long weekend is fun...) but maybe an idea for a product is a small "gamepad" type device that can be hooked up via I2C

[smoky island]

From the keyboard might tricky, it depends if you need like "held down" actions for the game, it would be hard to emulate over serial.

rewriting the code to use keypad with builtin or attached buttons is probably the easiest.

yes https://www.adafruit.com/product/5743

[wind spoke]

There is an adafruit product that does that.

[nova totem]

Oh it was already done too!

[wind spoke]

Or Wii accessories and the adafruit adapter.

[timid plover]

I need an index into my order - I see ordered it in May of 2023 - but I need to find it 🙂

[cunning cedar]

Is it slow to write the frame-buffer?

Woohooo! Declare victory!

[timid plover]

how much faster is the rp2350 than the last targeted host for celeste.py

or is it the new modules you are using now

are there other adafruit boards that have usbhost working
can they translate the buttons on your input devices to gpio, and then you can wire the gpio into the fruit jam gpio ?

[cunning cedar]

would 30 hz work?

[timid plover]

oh - how much bandwidth does DMA steal from the CP code ? any benchmarks ?

[glad mortar]

in theoery you could have DMA run on the second bank and CPY on the first maybe?

if I remember correctly they are not on a shared bus internally

[old surge]

[sand lotus]

Good morning. Game pad stuff neat. ☕

[nova totem]

👋 I'm avoiding fixing my toilet flush system here

USB HID stuff makes your head hurt quickly

May be too deep but the USB HID specification isn't too horrible read as specs go, to get the idea. I dove into it a lot making a controller (but not the host side)

[sand lotus]

It has to go into memory because it's a USB device? Analog read sounds easier to deal with.

What game controller or microcontroller are you trying to use with it out of curiosity.

64b might be an issue for smaller microcontrollers like an M0 (depending on other stuff) is my point. Some controllers have more ram than others to play with.

you forgot print f

I already got a SNES controller from adafruit but don't have a reason to use it just yet.

Always handy to have a controller laying around. (i don't own a gaming console)

looks like the bin hex already does what you sat down and coded for. unfortunate.

binary/hex weird format

maybe it's just a hex color code appended with an MSB for an LED?

FF0000FF = 4278190335 in decimal and FF00FFFF = 4278255615 in decimal. Seems like a weird way to go. It makes more sense if it's 4 pairs of 2 bytes.

i'm out of here, have a great weekend!

Lars pressure sensor

some not simply design lars for new finger tips what can sense touch

[sand lotus]

oh it's good for sip puff sensors. i completely misinterpreted the graphic. thought it was going to be for a weight sensor. 😬

hecto pascal is the same as millibar. 1:1 interchangeable nomenclature as far as i know.

[shell mason]

[tulip canyon]

Puff Puff pass

[sand lotus]

looks like a great sensor

[shell mason]

one not simply measure water pressure with it

djdevon you could think as stress toys could see pressure for it

i have seen one on more handle like pressure sensor to test grip strenght

[sand lotus]

i'm interested in it for barometric pressure for hurricanes. can never have too many baro sensors in FL.

[echo canopy]

Does it seem sensitive enough that if you put it between a storm door and the main house door it could sense the air change when one of the door opens?

[dawn magnet]

Is the an index of JP product picks?

[shell mason]

djdevon not for tire pressure?

[dawn magnet]

Thank you

[shell mason]

or window frame

[sand lotus]

You'd have to put a battery inside the tire to power the TPMS sensor... unless you could find a way to make it one of those inertia powered device. i honestly don't know how TPMS sensors work.

[tulip canyon]

Thanks JP

[open surge]

thanks JP

[haughty quiver]

thank you all!

[sand lotus]

I thank you JP, my wallet does not. 🙂

[shell mason]

well here in finland i have seen external tire pressure machines what can insert the pressure amount what is set so pressure sensor needed to measure compressor put enough air

[sand lotus]

Can never have too many sensors.

yeah for air compressors sure but in the actual tire for a TPMS sensor is a different animal.

or wheel i should say. i doubt it's built into the tire 😛

[shell mason]

for wheel it might have radio signal from wheel to car

[sand lotus]

i've always wondered how they stay powered to send the signal though... something to research out of curiosity.

[paper peak]

my impression the last time I had to have a bunch replaced is that they had a battery. They all failed around the same time.

🇸🇪 👋

[eager matrix]

Are you going to implement CPy on RP2040 at 200MHz? Is it just a recompile?

To be clear, 200Mhz is offically supported now so it's not overclocking.

[gritty falcon]

It may work on the 2350.

[dawn magnet]

Thank you

[bold roost]

Overclocking has been a breeze on CPy in my experience. 🙂

[glad mortar]

will be interesting where RP2350 will land there, I believe full verification is still under way

[gritty falcon]

Should be microcontroller.cpu[0].frequency

[glad mortar]

People have been able to push it to 600MHz so not unlikely it will land somewhere in the 300MHz+ range eventually

[gritty falcon]

Each CPU has its own frequency/voltage setting.

[unreal bay]

cooled? or more like super cooled?

and hey all 👋

[glad mortar]

no cooling, just bumping the vcore up, all within spec

[unreal bay]

wow, was imagining liquid nitrogen for 600MHz

[bold roost]

Do you have a public repo for this demo or are you planning on publishing it eventually? I'd love to see what it'll be like programming for the fruit jam.

[glad mortar]

you get M33 with 600MHz rating, it seems they just take a conservative approach. All down to silicon verification if all the peripherals play along at higher clocks

[unreal bay]

yeah fair, stability wins overall usually (except gamers)

[glad mortar]

if you know what you are doing you can clock up for number crunching, disable all peripherals while doing that and then clock down again for interacting with peripherals.
The CPU will be fine but everything else is most likely to glitch out eventually.

[smoky island]

How could we check if a USB device we have is high full or low speed?

[bold roost]

Once a good number of small games designed for the fruit jam are made, it would be great to have some kind of archive out there. Or maybe playground.

[glad mortar]

its very very rare though to encounter a low speed device these days

[timid plover]

off topic from the game - but I think I made a mistake by typing " git submodule update --init --recursive" after cloning the CP repo -
what is best practice ?

[open surge]

Or maybe a new kind of community bundle so you could install them with circup

[smoky island]

Thank you!

[glad mortar]

the low speed USB 1.0 spec was not in use for very long and very few devices have been made with it, almost any device is at the very least Full Speed

do you have VID/PID for that one?

[unreal bay]

can you show your camera and device mentioned?

I could imagine there might be some really old hosts around that are still relevant for gaming that whatever ancient IC this uses is still used for these HID devices

there is a possiblity though that they just messed up firmware and the IC is actually capable of full speed

[quiet nimbus]

Apologies if it was already asked:

RP 2350 Fruitjam release date?

[glad mortar]

USB negotiation is hard, bugs like that pop up quite often

[smoky island]

should it be expected for an exception to be raised if user code calls usb.core.device.read() and passes a buffer that is smaller than the amount of data there is to read? I was doing that accidentally at first and I think it was leading to hard fault memory errors.

[unreal bay]

Have you tried file access over usb much?

(setup your game to load as a rom off of usb, be a heck of a test setup) - like as if circuitpython was an emulator, and the ROM was the game application (stored on usb)

exactly yeah using a usb stick (mass storage device)

it does work, it's sketchy, maybe usb host issues, but it'll get there soon

[dawn magnet]

Just changed the Feather RP2040 to 200 MHz with microcontroller.cpu.frequency = 200000000

[unreal bay]

[timid plover]

usb question - were you making further use of the great scott gadgets usb analyzer ?

[steady osprey]

What mpu are you using again? I'm impressed that can all be done in CircuitPython

[glad mortar]

is the low-speed device issue mostly that it crashes things atm?

[unreal bay]

How many plants can you plant in a 20seconds (frame rate as they all grow)

[glad mortar]

bestest book 🙂

[steady osprey]

Just a little light reading

[wind spoke]

What is your best resolution that can fit 128x128 from pico8?

[glad mortar]

did you add support for low speed at all? Otherwise I would imagine its just confused about the pull up being on the wrong pair side

hm ok

[unreal bay]

Just remembered, got a question for the circuitpython / usb wizard... I only just discovered that the M4's have some examples that use a dual write access for the CIRCUITPY drive. Presumably it's just turning on or off some lock, as I've seen some tinyusb callbacks in the examples for duel access in c-land. So, does ESP32 etc also support that, and is it semi reliable but may cause complete file loss occasionally?

[glad mortar]

ooh, ok yea if that is just waiting for cycles that would blow up very quickly at any other clock speed

[timid plover]

when all else fails - read the directions - I see it was documented - https://learn.adafruit.com/building-circuitpython/build-circuitpython

"Fetch Submodules
We are not using git submodule update --init --recursive or git submodule update --init. Instead you run the special Makefile target make fetch-all-submodules at the top level, or make fetch-port-submodules when you in a particular ports/port-name directory."

[unreal bay]

Yeah, the example only stored a cache.bmp on the drive, so the host would be accessing code etc but the circuitpython device wouldn't in general so no clashes

[glad mortar]

should be fixable if you make it cpuclk dependent cycle wait I guess?

[timid plover]

I made the mistake 🙂

[glad mortar]

but also can't you use computed us from the SDK? Feels odd that it uses such a hack for timing

[unreal bay]

Okay, so I can't remember clearly but think the tinyusb examples would resync after dual access changes

[glad mortar]

right

Arduino generally does very little, should not be an issue to just change that 🙂

[unreal bay]

cant see that side of diff/ screen

[glad mortar]

would the crc at this point be even costly?

man USB controllers are a lot

I could do a capture with my Beagle if it helps

that usually shows you stuff like timeout errors pretty easily

ah nice

If you want to output a 128 by 128 framebuffer over DVI using HSTX, I believe the lowest resolution that would have only a single pair of pillarboxes, and doesn't cutoff any pixels, would be XGA at 1024 by 768, pixel-sextupled. Though I'm curious if the RP2350 can even handle that large of an output.

[timid plover]

what page ?

[unreal bay]

ok, I'm half convinced, although could the perfect storm mean 3 !=2

[timid plover]

yes - it was small on your screen 🙂

[glad mortar]

https://www.raspberrypi.com/documentation/pico-sdk/hardware.html#group_hardware_ticks

[timid plover]

it moved between the rp2040 and the rp2350

we let it free run

no

not in sdk - I'll look

[glad mortar]

are you sure? it refers to cycles not us

microseconds should be one layer above in the time api

[timid plover]

src/rp2350/hardware_structs/include/hardware/structs/systick.h

[glad mortar]

do you not want a tick per clock?

[timid plover]

I don't see systick_hw_t except in the header files - maybe it is free for uses to use

like you said - it's an arm thing - do any other CP arm processors access it?

it's per core also

yes - systick -sorry

[old surge]

https://www.raspberrypi.com/documentation/pico-sdk/hardware.html#group_hardware_clocks

[glad mortar]

maybe verify first that you changes to the timeout is actually doing what is expected?

I tend to keep my Beagle in the loop and do a capture anytime I do a change, I find it often helps seeing what is on the wire and have it be decoded.

how do you mean? Is it not a type A on the Fruit Jam?

I don't quite understand but I believe you that you can't hook it up heh

[timid plover]

I remember Lady Ada talked about hub chips recently - but I forgot that Fruit Jam had the hub - thanks for the reminder

[glad mortar]

ooh ok so there is a usb hub between rp2350 and device?

right yea that is difficult then if it fails at this low level

hm maybe wire up a type A on another RP2350 board for testing?

oh nice

[timid plover]

I bet theres an rp2350 Metro in the office 🙂

yours Scott

mine came in the mail today too

I forgot to order the USB breakout for it

[glad mortar]

didn't you ask for the Metro to have the breakout for host? 😄

fair

[unreal bay]

does the max3421E or usb host in general work with hubs now then? (maybe it already did). Maybe I'm getting confused with composite devices

[timid plover]

that might be a Monday problem too 🙂

[steady osprey]

I could never livestream my programming sessions. There would be too much profanity.

[timid plover]

it's amazing how much they pick up quickly ( youngsters that is )

no worry - it's nice to wrap up on success - but sometimes you can just look forward to the future success 🙂

does tinyusb use interrupts ?

sort of like a breakpoint

[smoky island]

I am getting started for this morning's stream. Working on some improvements to the emoji text library. You can follow along on twitch: https://www.twitch.tv/foamyguy_twitch or YT: https://www.youtube.com/watch?v=VTQFw9nA_Bs

[sand lotus]

Good morning ☕

[open surge]

morning!

[unreal bay]

Hey 👋
So I've half followed your emoji talk / work, and I wonder if it's a font or a replacement label type or tile grid, and effectively how would I get it running on a matrix portal M4 or pyportal? Presumably your using displayIO to an HSTX to DVI/HDMI thingy

Got you, do it looks a bit like a bitmaplabel replacement type thing

[sand lotus]

If HSTX can go to DVI you can use a DVI capture dongle (adafruit sells) that will work nicely with OBS. Might be a problem trying to use a capture dongle and a TFT display at the same time.

Maybe a linux issue. I didn't get any of those issue with windows. Yes the one Adafruit sells is the one I've used, it works nicely.

[unreal bay]

Maybe some crazy udev rule could ensure the device naming and ordering so obs behaved, it's a shame it's all pretty complex

[brisk bone]

May I have a question about what you showed at Show and Tell? If I understand corectly, I should be able to connect and Xbox controller to USB Host Feather, read its hid descriptor and then simulate specific key presses on a different Feather. I had some problems defining the descriptor myself as the Xbox uses 1024 range for sticks and the example used 128 if I am corect.

[sand lotus]

Yes that's unicode. How much file storage does the emoji's take? I'm on an S3 with 16MB flash but not everyone will have that much space.

[unreal bay]

I've been thinking about ota-like behaviour for Circuitpython. It would get from GitHub, check sha and then save using set_next_codr_file and boot.py to use latest copy with old copy as fallback run by safety script on error.
Long story short the code.py could offer to download the latest emojis

[brisk bone]

I believe the difference in total files size might be caused by allocation unit size, which might be different for your PC and the MCu built-in drive.

I wanted to use another Feather as a HID gadget which would simulate an Xbox controller, like you can do with keyboard.

[unreal bay]

Forgot zip issue

Fine if not zipped assets

[smoky island]

https://learn.adafruit.com/custom-hid-devices-in-circuitpython/report-descriptors

[sand lotus]

The controller Adafruit sells is called the "SNES" I think. There's probably a SNES learn guide.

[brisk bone]

Thank you. Yeah I found that, and I had problems with custom report descriptors, so I was hoping I could copy paste one from reading it off the Xbox controller.

[inner spade]

… and within the class, the emoji/text palette is available for manipulation, as well. Could it be exposed as a property?

[sand lotus]

this is turning out to be far more complex than i would have thought.

[inner spade]

With the palette exposed, it could be used to control brightness on an RGB matrix panel.

[sand lotus]

group.remove or group.pop?

I don't think pop removes it from memory but remove will. That's my understanding though I've never actually tracked memory usage to confirm that.

Yeah I think del is removing it from an array and remove uses a group object.

I think of it as add/remove (objects) and insert/delete (array indexes) that are used together.

I think insert is used with an index though I've never used them much. I almost exclusively use object append/remove syntax. I find it easier. Since you're working with arrays you'll likely want to use insert/delete more than append/remove.

[brisk bone]

Could you explain what the current problem is? I lost you somewhere along

How about using the (index, tilegrid) as a key in dict?

Would that work?

[sand lotus]

Does the emoji repo state that they are indexed and/or indexed properly to have the background as 0 index?

Looks like that is working well to me. Is there an issue with always using the index value? That would basically make them the same as an indexed bmp.

Ah yes because emojis have color. Bit different than single color font glyphs. That complicates things.

[wind spoke]

What if there is always a background colour, but you can choose for it to be transparent?

[brisk bone]

Thanks for the stream, have a nice week

[inner spade]

Thanks!

Automotive uses float sensors for fuel tanks. Could go with a 12v automotive float and then adapt it.

[mellow arrow]

I completely understand and agree how a "modern" 8-bit microcontroller is niche and when CircuitPython support is a foundation capability, there are a lot of better place to put limited resources.

[severe inlet]

Somewhere I recently saw a quote regarding redundant sensors, and the quote was basically you should have either one or three sensors. With two, you don't know which to trust.

The backgrtound oscilloscope art is spitting image of a very early animal ... silurian age

[sand lotus]

That adds another layer of complexity. A float sensor is just a variable resistor that changes value depending on the level of the arm. It's how your fuel gauge works. It can tell you the level of water in the sump with the correct arm fulcrum.

and if you pair it with a fuel pump you could actually use the fuel pump to evacuate water.. to a point.

[fresh imp]

Oh, i see...i was thinking it was closer to a switch.

[sand lotus]

I actually have a youtube episode where I install a fuel pump in my car. Got to see one up close and how it works. They're extremely simple devices.

You'd need a microcontroller to control the logic so the fuel pump only turns on when the fuel level is full (sump leak). It's doable.

I would not use a fuel pump as a replacement for a good sump pump though.

[fresh imp]

Nope. Welp, hope whoever has that project can figure something out.

Hello Scott

[timid plover]

internal only orders? 🙂

I have my metro rp2350 plugged in at the moment 🙂

digikey or adafruit?

(the clip ? )

[gritty falcon]

What drove the decision to not run picodvi on core1?

[wind spoke]

Why a MAX3421E was not put on the Fruit Jam and not use PIO for the USB side. Just because it is possible by software?
Could the RP2350 have done other stuff with PIO, or anyway you have enough PIO?

[gritty falcon]

That is so cool. Thanks for the explanation!

I'm guessing that means that USB host and picodvi can't work concurrently on the RP2040?

[wind spoke]

Any practical use for the EYESPI, or is the work concentrated on the "HDMI"

[vagrant flax]

I liked the trick you did for the simple text "computer" where you used two RP2040 Feathers, one for USB and the other for DVI

at least your mike is on the other side of your

Really like those switchable USB C to A's, they allow separating power and data (ignoring small drain on data). Would they work as just a socket (connecting d+/- vcc gnd to host mcu) ?
Also why is the qtpy monitoring your trackball usage, you've got me curious...

[timid plover]

did you see a cable with pins on the other end of the cable ?

[unreal bay]

omg that's clever, auto-macro mode via capacitive touch on mouse

[timid plover]

Hi Scott. Just joined, I was on the bus to my mother's to visit for the weekend.

[timid plover]

maybe set the cursor to an alternate area for the debug output ( like the right had side )

or send the debug output to the serial port?

when you mentioned keypad being broken, were you referring to the usb keypad login non-functional in fruit jam firmware ? or just in the python code ?

why did you need the repr - ( just to view the string? )

[unreal bay]

using traceback library?

[timid plover]

is that the function of the clear?

could it remember in RAM, or do you need a file ?

[unreal bay]

I can imagine using sleep memory, but now you have me curious if there is anything that survives code.py ending/erroring and doesn't write to flash/nvm

[wind spoke]

Is there a "risk" in writing to flash/nvram too frequently but always at the same place, like this: import microcontroller microcontroller.nvm[0] ?

[timid plover]

like a ram disk?

[unreal bay]

ooo like a data drive, or Shared

[timid plover]

yes - a writable file system is great!

[glad mortar]

yea I think that would be a good idea. We did something along those lines for flow3r which had similar problems to solve

[gritty falcon]

Good idea. Would we try to have another mass storage USB endpoint as well?

[wind spoke]

And that save would be accessible write from CP, but will it be visible from the host?

[old surge]

But is there enough memory to save New Jersey?

[wind spoke]

It could be the SD card? Like a memory card in game console...

[glad mortar]

apps could save to the internal flash but also to the sdcard that was permanently installed and that sdcard would stay intact between a full wipe. The system would take care of writing to both places as a backup option.

which is what we did for flow3r

we also installed apps onto the SD for that reason so that a firmware update would not wipe away all your apps

[wind spoke]

Talking about SD card, I made a thing where in boot.py you check if there is an SD card, and in that case run the game from the SD card and not from the internal flash.
So it behave like a game cartrige.

Adafruit sells very small SD card. 😉

[glad mortar]

ah yea doesn't matter it being an SD, it was just what we had, could also be a second spi flash

[unreal bay]

I wondered bout having a Unstable folder for dual access files, then circuitpython controls, but pc can read if desired (user knows to not touch so less likely to corrupt). The separate partition makes more sense but similar issues.

[glad mortar]

but if you plan on having a whole apps system it might make sense to have mandatory SDcard

because some might get very big asset wise

[timid plover]

what's the relative speed difference for writing to internal flash vs. sd card?

[glad mortar]

you can also do SDIO via PIO so would be pretty fast

[unreal bay]

Cloud saves?

[glad mortar]

you underestimate how little people think about how little space these devices have 🙂

[timid plover]

a new adafruit service

( cloud saves)

[wind spoke]

Adafruit IO cloud save...

[glad mortar]

we had people do tetris with a 8MB music file for the theme

[gritty falcon]

The big boost for internal flash is the XIP cache.

[glad mortar]

as soon as you give people sound and video they go off

[wind spoke]

Can we plug extra storage on the EYESPI?
This must be the place to extend the Fruit Jam like a SEGA console.

[unreal bay]

Thought it just broke out SPI and I2C so probably yes?

[timid plover]

I did not realize that the xterm set title escape codes are different from https://docs.circuitpython.org/en/latest/shared-bindings/terminalio/

xterm ends the title with \7

[wind spoke]

VT100 rulez

[unreal bay]

So with VT100 we could have a scrolling title on REPL, like informing users or something

stock ticker for example

[old surge]

'Select' to menu?

[unreal bay]

Hold select then dpad for 1 to 4 (like compass start at north)

Maybe more like a cheat code then

[wind spoke]

Konami code.

[timid plover]

you can fix it 🙂

[old surge]

⬇️ ⬆️ ⬅️ ⬅️ 🇦 ➡️ ⬇️

[timid plover]

10 minutes till your hard stop .....

[wind spoke]

Is terminal.io always full screen, or can it be a "window" into the screen?

[unreal bay]

You used to be able to set it to a group after removing it first, I had half window as terminal

[gritty falcon]

I'm probably missing something obvious, but I'm not seeing DEFAULT_DVI_BUS_CLK_DP defined for the fruit jam?

[wind spoke]

So for the MagTag, there was a menu system to select the function (and saved for next boot too), and a way to copy multiple learn guide application next to each other on the flash. There is a learn guide for that.

https://learn.adafruit.com/adafruit-magtag-project-selector

[gritty falcon]

Cool, just a WIP thing then.

[unreal bay]

Oh was that using the pyleap app, downloading from list of guides? Think I saw that when looking at BLE, and there was also S2/magtag support for some projects.

[wind spoke]

I made a PoC and then someone from Adafruit turned that into a graphical thing and made the learn guide.

[old surge]

Any tips/hints for pulling out the CtPy interpreter/runtime to play around with it on a pc?

[wind spoke]

You need to define a "format" where each learn guide for the Fruit Jam provide an icon, a display name, some info if a joystic is needed.
Then you can have a bootstrap code that let the user select a project.

[old surge]

Is it straight MicroPython? Any changes?

[unreal bay]

This is what I was thinking of, similar but maybe not quite:
https://github.com/adafruit/PyLeap-Android/blob/d2223c45163be9ab2d0554d9d179ae5a4bbcd18f/app/src/debug/assets/pyleapProjects.json#L4

[gritty falcon]

[old surge]

Have a great weekend, everyone!

[rapid hornet]

true!

[wind spoke]

And if something is missing: "Ho but I have code for that in C!"

[smoky island]

I am getting started with this morning's stream. Working on a snake game for the metro rp2350. You can follow along on twitch: https://www.twitch.tv/foamyguy_twitch and YT: https://www.youtube.com/watch?v=XpPi_pflylc

[nova totem]

👋 I think I need that HDMI board still, got the cable only

[unreal bay]

HSTX to hdmi/DVI breakout?
And hi fellow snake fans 🐍

[inner spade]

👋 ☕

[timid plover]

draw a boarder ?

[unreal bay]

Does speed increase with each apple, like length? Could have multiple apples, 🍎🍏 have a red one that slows, and some greens that speed up

Both grow

[unreal bay]

Speed adjust helper, pass in -1/1 and let it deal with it elsewhere in helper

[timid plover]

does CP have an implied decimal math system - where the number is stored in an integer but the decimal point is implied - eg where 1 is stored in the integer as 100?

[upper sandal]

dunno what that is, but CP has floats that are stored as floats

[unreal bay]

That was really interesting, clean integer division giving a clean rounding in decimal style when printed, compared to float usage. I wonder what the different code looks like...

[inner spade]

Jepler’s udecimal works like cpython’s decimal. udecimal is in the CircuitPython Community Library.

[upper sandal]

excuse me I just arrived, what's the weirdness ?

oh float arithmetics yeah

[unreal bay]

I guess the interesting bit is how it chooses the precision to show

[floats always being bad/imprecise representations]

[upper sandal]

yeah the REPL/print choses a different representation than you get with string formatting

[unreal bay]

Long term the user could maybe choose the number of greens [or built in mechanic], still one red, which could appear later but for a while and slowly flash to disappear [or rots away]

The green one is under red [red appeared over it]

Does the IDE have compare between

Red seemed to speed up

Definitely start faster. Just before it's at the point where you don't have time to find the correct keys on keyboard before crashing into top

Be nice if starts in larger chunks, gets proportionally less, and red gets a little more effective with higher speeds

I like that, made me then think of a tree in middle with single pixel apples that grow to two/3 and fall/bounce around and become full size when stopped/Landed

Good luck future Tim

[inner spade]

Thank you for today’s stream!

[ancient grotto]

Hello!

Helpful to simulate neopixel or matrix (es) easier

[nova totem]

I've spent too much time in this code before

[ancient grotto]

What boards will have this functionality by default?

[old surge]

That was a really good episode - very cool to hear about the evolution of the weather station project

Looking forward to your guest appearance on the CtPy Podcast - have you already worked out a topic?

[inner spade]

Thanks. Was/continues to be a fun and challenging project.

[old surge]

I was reminded so often of the dictum (told to me as a student, and expressed to my own students) 'writing is never done, it's due'

[inner spade]

todbot and I are on next Monday’s episode talking about making a library for the Community Bundle.

[nova totem]

can't you just use int32 then? its a bit of waste if you only need int16 but not a ton

or you do something like

int16_t* num16 = (int16_t)numbers;```

(that's not quite right but sorta like that)

num16 would hold 40 int16s in the same memory space at "numbers"

Yeah so not really a space saving unless you dynamically allocate memory

your pointer says how "big" a space it will write to, it doesn't care where it is.

Or just use uint32s if you don't worry too much about a few bytes (even say 256 values at 2 bytes each)

C doesn't do type checking so you can have an uint16_t a = 0 and then go a=a-1 and it will happily go to 0xFFFFFFFF

Yes you can put hex in C

But -1 is the same as max int (or close to forget the internal format).

[old surge]

Huh, I'm not sure I knew that 'indention' === 'indentation'

I just have always used the latter

Yes, no wonder folks find English to be such a difficult language to learn 😅

Thanks for the stream, sorry not to have one tomorrow!

[ancient grotto]

Thank you. Great work!
