[brisk bone]

I used to do that for dashboards with Selenium

[unreal bay]

Was there some xfb (x frame buffer) for headless setups. Oh display env var looks familiar

[brisk bone]

It was like DISPLAY=":1" because ":0" was the terminal or something like that

Also, you might want to print/set the env in the python script itself, as I am not sure it is passsed from terminal to python process, or whether the python does overwrite it by default

That is convinient, good alternative to rsync'ing

In Selenium setting the DISPLAY is enough

[unreal bay]

Isn't there some CSS for break word

[brisk bone]

I believe the "default" is browser dependent, like styles for inputs, buttons etc.

[unreal bay]

Think it said break-word was deprecated value

Thanks for clearing that up!

[unreal bay]

Didn't see the problem sorry, but if it says connecting then refresh

Maybe only multi page guides get Reorganise

Normally for me connecting takes a bit but no more than 5-10secs. Otherwise I refresh.

WE ARE LIVE! Desk of Ladyada - Lots of Motor Drivers this week + RP2350B Metro ⚙️💥🚀🔍

This week on Desk of Ladyada: A look inside North Korean missiles. Motor drivers galore, prototypes for A4988, TMC2209, and TMC2130 are here, plus a detour with ‘Newxie,’ a retro-style 1.14" TFT. Metro RP2350B boards arrived—CircuitPython support coming soon! Also, NEMA-23 stepper fun on The Great Search! https://youtu.be/jCrtF7x_UEQ

I have had problems getting these 2.4 Ghz Wifi devices to connect to my Ubiquiti (and other brands too) WiFi network that has both 2.4 Ghz and 5 Ghz bands. Any experience with this?

[cinder wind]

I've heard some folks make a separate "devices" network in UniFi that is 2.4 GHz only. I think this is because by default, the Ubiquiti stuff will try to switch a device to 5GHz

[heady pagoda]

and try WPA instead of WPA2

[halcyon pagoda]

Running a separate router is how I have solved it, but was hoping to a neater solution. Thanks!

I have Amplifi equipment by ubiquiti, and they have an option for a separate SSID for each band, plus a separate "IOT" SSID only on the 2.4 ghz band. I would assume they offer a comparable feature on the higher end gear

[bold roost]

@robust horizon Have you played around with QuickDisk yet within all of your floppy pursuits? I have a couple of Roland synthesizers with dying drives that use that strange format.

[robust horizon]

@bold roost no, I have not. Just having a glance at https://github.com/keirf/FlashFloppy/wiki/Quick-Disk I know that floppsy doesn't have a flashfloppy-style jumper block for different drive selection scenarios, so emulating the drive may not be possible without some shenanigans like a custom cable

oh it was also used on famicom disk system? interesting!

[smoky island]

That is a slick programmer widget! great job @mellow arrow

[bold roost]

It's a very strange format. Mechanically, it works like a record player in that there aren't fixed segment lengths, but instead reads the entire disk.

[robust horizon]

Unusually, the Quick Disk utilizes "a continuous linear tracking of the head and thus creates a single spiral track along the disk similar to a record groove."[45] This has led some to compare it more to a "tape-stream" unit than typically what is thought of as a random-access disk drive.[47]

that's real interesting. thanks for mentioning it.

Hey Tim, I had a couple displays that if I applied a rotation, even rotation 0, it performed much slower. I think the Qualia and Funhouse? Is that displayio in general or each display type?

[turbid hill]

While you pursue code, The instructions on the website for PyCharm + Circuitpython need updating. The PyCharm used in the instructions has been updated, and they shifted some stuff around, some new screenshots and better instructions on attaching CIRCUITPY to the project.

The extensive long list that never ends. Hmm.

Good morning! Hope you had a nice Thanksgiving

[unreal bay]

Hey all

[clever summit]

Good Evening!

[inner spade]

☕

@unreal bay Simultaneously tested throttling with five autonomous AIO devices yesterday. Success! Three PyPortals, a Matrix Portal M4, and an ESP32-S3 Feather. I’m a happy camper. Thanks again for your work.

[unreal bay]

Yay, throttling info for the win. Got to admit that I'm still just waiting for a message on the throttle / error topic and then stripping out the wait time (+random offset) before reconnect/reset.
I need to think carefully before I update a few projects 🤔

[inner spade]

In this implementation, each device watches the remaining transactions when they need to access a feed, then waits until enough “points” are available. It can cause a delay, but a second or two isn’t critical for my project.

It was very satisfying to watch three of the devices taking turns accessing shared feeds, one feed value at a time.

[unreal bay]

Yeah that's good. I'm a little worried about two devices thinking they have a clear run, and then both publishing far too many (11+) data points and blowing the budget. It'd be fine as each would just back off when needed, but I'd prefer them to finish one at a time (then they could deep sleep). Minor, I should just get on with it...

[inner spade]

I set the availability threshold higher than needed to keep it away from the budget limit. Also, the wait time granularity of a device’s feed transaction was set to one second, more than enough to allow the availability to grow. That’s the sacrificial delay. Wouldn’t be compatible with a time critical project.

[unreal bay]

Yay we have a Dot 🔵

Need a background colour

Think it will reduce clarity, except for edge visibility tests

Does the logging affect it, maybe reduce log level to avoid all the string generation

I feel like having the coordinates begin 0,0 for the convenience of zero based indexes is a real mistake. It messes with all the calcs to take 1 off of width/height but in rotation orientation.

Delta x, I.e. change from initial

Is that the delta for coords plus rotation

Other rotations?

[unreal bay]

Nice one Tim!

You can of course use just about any USB audio interface with the Pi. There also exist various "Raspberry Pi Audio Hats", some of which have line/mic inputs. e.g. here's one example: https://amzn.to/3CYM2us

All good on twitch

[timid plover]

I saw there were several learn guides for zephyr on adafruit products -

which are you using today

I also saw some news about zephyr and arduino - did this affect your choice ?

[eager matrix]

Hi Scott, congratulations on the new one.

How does Zephyr compare to FreeRTOS?

+1 on using an RTOS

[unreal bay]

So on esp do you mostly rely on the freeRTOS where possible or more keep it only for tasks.

[eager matrix]

By any chance is Mynewt tan?

[unreal bay]

I remember zephyr being the new choice for SBCs back in the Qualcomm dragonboard days (96boards had a standard SBC footprint)

[eager matrix]

I'm excited that you'll have an RTOS supported on your boards. It'll make a lot of thing easier for me.

[unreal bay]

So you intend (eventually) for things that are currently compile time decisions to be allowed to change at runtime in zephyr. Like the i2c pins/speed and BLE services (no idea if supported)

[gusty wedge]

Hi from Costa Rica

Will this enable OTA-updates to cpy?

[shell mason]

having the base stuf then specific stuff

sounds great plan anyway

[timid plover]

we've done some work to extricate cmake from our rp2040 builds while still using the rp2040 SDK

we found it hard to understand what cmake is doing, - and try to build a flatter project directory and make/and other scripting languages

[velvet valve]

It's possible to develop Zephyr without West, but still using CMake (but IMO you're better off using west :D) https://docs.zephyrproject.org/latest/develop/west/without-west.html

[gusty wedge]

Yeah, it's a nice way to future-proof circuitpython.

[unreal bay]

Yeah baby lvgl for all

To be fair there's a micro python port

Ah

[tulip canyon]

LVGL looks neat, I had not seen that

[velvet valve]

k_heap? https://docs.zephyrproject.org/latest/kernel/memory_management/heap.html

I'm pretty sure k_heap is the high-level heap allocator. sys is lower level.

[unreal bay]

Checkout Lvgl with tasmota and berry script. It's clever, json lines per screen/widgets set, but for serious use you'll want to look at the free official screen editors instead (or https://github.com/eez-open/studio )

[timid plover]

this is great

what are the root pointers ?

thanks - i didn't think they were related to qstrs 🙂

I see that we definitely need to do this outside the CMake process - makes sense

oh

you've used perfetton on a few other projects - it looks like a great visualization tool (that I need to explore )

does CP do the heap synchronization or do you want Zypher to do it?

from the docs

The core port initialization and reset methods are defined in
supervisor/port.c and should be the first to be implemented. It's required
that they be implemented in the supervisor directory within the port
directory. That way, they are always in the expected place.

so your port.c is under supervisor/zypher, but the other files are just under supervisor/ ?

I figured you had a reason 🙂

[lyric frost]

So all boards added to CP will need to be supported by Zephyr also?

Isn't Zephyr becoming your interface to the ports sdk?

[tulip canyon]

Maybe a silly question... Would Zephyr running with both CircuitPython and Arduino support ever be able to run at the same time on multicore boards?

[timid plover]

when you get an undefined reference, how do you see what is being linked ( or searched )
earlier you mentioned creating a .a library - what does nm tell you about that symbol in the library

that makes sense !

[lyric frost]

Thanks Scott! It will be nice having a bit more of an idea what the devs are talking about with Zephyr comes up 😁 Dinner bell is ringing, have a great night everyone...

[timid plover]

is the heap defined in that .cmd file?

what was the sys_mem section ?

did you see heap mention in the .ld files?

chatgpt mentions CONFIG_HEAP_MEM_POOL_SIZE

no other clues in the .map file you looked at earler ?

I'll try to catch the other timecodes later.... stepping away

[unreal bay]

Here's a random question for you: Ever done an in-memory only app for esp. Reason being you can load into ram using esptool (think esptool-js) then say execute, so I plan to have a mini firmware/app to interrogate the board when troubleshooting for new users. In my head it sounds good 😊 sort of a more generic version of a Serial Doctor (listens to serial and follows troubleshooting flow charts) where your target board doesn't normally print needed info, and you don't want to overwrite the users flash.

Thanks Scott, have a great holiday season!

I am getting started for the morning. Seeing how far along I can get implementing Karel the robot. You can follow along on YT: https://www.youtube.com/watch?v=tdoTu11jing or twitch: https://www.twitch.tv/foamyguy_twitch

[ancient grotto]

Hello

[inner spade]

👋☕

[noble grove]

Just got here: So Karel is like an alternative to Turtle Graphics?

[noble grove]

Is there a way to edit the Karel program without CP restarting?

I guess you'd have to implement a Karel REPL...

...on top of CP

I believe turnleft is a primitive, and is standard to explicitly define turnright as 'turnleft, turnleft, turnleft'

[brisk bone]

This looks very similar to one of this year's Advent of Code tasks

[noble grove]

Looks like it's stopping too soon

[inner spade]

First played with Terrapin Logo many years ago. Fun learning tool.

The CircuitPython turtle library works nicely, too.

[brisk bone]

Cool, very good visualisation, I joined a bit late and didn't know you mentioned it already

[noble grove]

Technically CGrover's robot should be able to do turtle but would be trivial to restrict rotations to 90 degree increments.

could put dice pips inside the beeper, or different colours

Is there a different Karel icon that shows beepersInBag?

[inner spade]

The tough part of the robot implementation was controlling the brushed DC motors — no steppers. Led to a deep rathole and a motor tester apparatus.

[noble grove]

maybe add 'tryPickBeeper'

If you can paintCorner, can you check colour of the corner you are on?

Maybe 'Extra' features is 'todo'

...or in a library

but then you would expect it to error on the function name, not the parameter.

paintCorner

They are probably not using sprites to render the walls

could make the icon turn pause move

when changing directions

maybe put the delay before move instead of turn

at the begining of move

Could put a shorter delay in turnLeft than in move

Thanks Tim

[inner spade]

Thanks! Looking forward to the next stream.

[ancient grotto]

Thanks Tim

[noble grove]

Could use paint to create soft walls, paths, or implement Piet in Karel.

[upbeat coral]

I like the pivot

How about a mount to the new CM5 IO board case?

[cunning cedar]

If the led strip were mounted on an angle/helically, The apparent density could be higher

[upbeat coral]

Compute Modules are THE way to go if you want a versatile system.

[halcyon pagoda]

The picture you were showing for the Raspberry Pi CM5 was the IO board, not the actual module itself.

The Module has high density connectors only and is designed to be integrated into a custom PCB that has exactly the IO and connectors you need.

[upbeat coral]

The CM5 module will work on the old IO Board and the new IO board. Doing experiments with interchanging them as we speak.

[halcyon pagoda]

@upbeat coral that is very cool.

[upbeat coral]

@halcyon pagoda I have a CM5 IO board witha 1tb nvme running the Raspberry Pi OS on the CM5 4g with eMMC that is doing >700000 sequential write.

Running circles around all my other Pis

FYI the eMMC only gets about 100000 sequential writes,

Little Snow man is cute as all get out.

[halcyon pagoda]

Very nice performance.

[vagrant flax]

Thanks for the show! 😄

[halcyon pagoda]

I have about 6 RP4s running off SATA SSDs connected via the USB3 port. Terrible IO compared to what you have above but worlds above the Micro SD card plus the SSD tends to have a much longer life than booting off a MicroSD and running off it with all the log file writes. A microSD card tends to last about 1 year (really 14-18 months) booting linux and then dies. You can do work arounds like mounting a different volume as the /var directory but that either uses RAM or Network, or another drive on USB so might as well boot off the SSD to start with 🙂

BT would work, or use USB

I have had the Pi5 running BT audio

Rubber Duck shower speaker 🙂

[upbeat coral]

I find that all variations of the Pi5 run BT better better and more reliable.

[halcyon pagoda]

Thanks Y'all

[nova totem]

Very very cool Noe

[haughty quiver]

so great!

[dry shore]

i still need to look into the new PIO stuff on the pi5
i was messing with it back when it was undocumented, so i was far more bare-metal with it

[cinder wind]

I want to play Asteroids on your cylinder display, @hard hollow 🙂

[viral sail]

Great work everyone. Thanks for sharing.

[vagrant flax]

Thanks everyone!

[tulip canyon]

Thanks everyone

[upbeat coral]

Thanks to all for sharing

[dry shore]

like the rp2040 stuff, a pio block can take a 32bit value from the fifo, and present it on up to 32 pins (but only ~27? are usable on the pi5)
so if you could encode 27 neopixel streams into an array of 32bit values, then you could drive 27 strings at once, with different PIO code

[robust horizon]

@dry shore do you know is the PIO pin mapping the same as the D# mapping in blinka? we didn't know if there was a translation layer at some low level...

(cool that you were doing this before it was official! i found a few snippets of code, maybe something of yours)

[dry shore]

no funky numbering

gpio 0, from the hw numbering, is also 0 in the pio numbering

[robust horizon]

That's good! Then if StateMachine gets to the necessary point, neopxl8 might Just Work for driving up to 8 strips on 8 numerically contiguous pins.

[dry shore]

yep

from the RP1 datasheet

[robust horizon]

rp1pio.StateMachine work in progress, which will be a bit on hold for now: https://github.com/jepler/Adafruit_Blinka_rp1pio

[dry shore]

alt7 maps any pin to pio, across the board

alt5 maps the pin to a gpio block in the pcie space, so the main SoC can bit-bang it

[robust horizon]

only supports a few of the things rp2pio.StateMachine supports, but enough to run neopixels

[dry shore]

and alt6 is instead maps it to an RIO block, that only the cortex-m3 can access

the rest of the modes are just a random grab-bag of peripherals

[robust horizon]

did you spot any differences in PIO instruction set compared to rp2040?

[dry shore]

no differences that i could find in the instruction set

[robust horizon]

excellent, since they didn't provide a compiler

[dry shore]

biggest change, is that the FIFO's are double the size

so there needs to be an extra register to report the fifo levels

which then moves all of the registers around

dma enable is also a little funky

[robust horizon]

yeah the ioctl API doesn't seem to support async DMA or simultaneous read/write DMA. I hadn't noticed the increased FIFO depth either.

[dry shore]

ah yes, and the PIO control registers (including fifo level/status) can only be read by the cortex-M3

[open girder]

WE ARE LIVE in BROOKLYN! ASK AN ENGINEER! https://youtu.be/M0zju77YW8o

[tulip canyon]

Freaked my cats out for a second time

Parsec does it too

[dry shore]

oh yes, dma writes (host->pio->pins) are fairly safe and easy
but i had a lot of issues with dma reads (pins->pio->host), the dma controller would jam up and cant cancel if PIO doesnt reply with enough words
and if the PIO outputs words too quickly and doesnt use a blocking push, you loose samples

Could the goal state not care where Karel is, just beepers and paint colours?

to allow for 'other solutions'

So could the goal state care/not care about any particular 'objects'

Right

Got it.

Makes sense. 8 chapters = 'port' Anything more = 'fork'

Negative 1 for nul tiles?

I suppose for three bits, -1 = 7. i.e. your 'blank' tile

Is there any other way of coding other than iterative though? Some use compilers but it's all an iterative process in one way or another.

One of the great things about python and circuit python is the iterations are faster. Really suits trial and error learning.

Happy New Year John, Figured you would be taking today off.

[drowsy inlet]

hello all. made it to the last one!

[haughty quiver]

woot!

[inner spade]

It’s an automatic shifter — no clutch needed.

[waxen bough]

Being New Years Eve, I may be slightly pixilated tonight. Not to be confused with pixelated.

[drowsy inlet]

had no idea there were lights like that. so cool

thanks for that info jp!

[waxen bough]

I think there was a note on the project page that says this can be used as a generic level shifter from 3.3 to 5 volt devices, not just pixels?

[viral sail]

Thanks @haughty quiver

[drowsy inlet]

happy new year all!

[haughty quiver]

@waxen bough yes! i haven't tried that but it is a nice plug and play level shifter for any kind of project you may have.

may want to disable the onboard neopixel in that case

[inner spade]

Thanks JP! Happy New Year!🎊

[haughty quiver]

🥂

[drowsy inlet]

why did the onboard color not match the output color? was it the difference in rgb order?

[haughty quiver]

yes, that's it exactly @drowsy inlet

on-board is typical NeoPixel WS2812 order which I think is GRB

[waxen bough]

JP explained that right at the end of the presentation.

[haughty quiver]

this strand is RBG because of Ruth

a.k.a. "Supreme" pixel order

(I stole that joke from @cinder wind )

Pico W BLE support maybe via Zephyr down the line 🙂
There is existing support for BT HCI for the Cypress chip they use but not sure how custom RPIs specific implementation is. It sounded like they might not have a standard HCI available.

[wind spoke]

Connection manager was the answer for the network issue.

[glad mortar]

CYW43439 is the IC

ah but seems to only address WiFi?

[timid plover]

what do you mean "get out of this business"

[glad mortar]

there is https://docs.zephyrproject.org/latest/build/dts/api/bindings/bluetooth/infineon%2Ccyw43xxx-bt-hci.html
might just be that its two different interfaces for BLE and WiFi

for sure this becomes such a huge headache when you deal with multiple very different SoCs

[glad mortar]

the joys of python package management 😄

it has gotten worse for sure :/

it does get updated but its a native tool

are you running native zephyr and zephyr-sdk or nRF Connect?

nrfutil should be part of the SDK (aka toolchain)

yea I hate that about nRF Connect

https://docs.nordicsemi.com/bundle/nrfutil/page/guides/installing.html#prerequisites

[timid plover]

at least linux has strace to see what the blob is doing ?

[glad mortar]

the blob self updates

but it is the actual utility, not a downloader

[timid plover]

https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/nrf-util-unified-command-line-utility

[glad mortar]

its annoying that you need it at all, the only reason you need it is to be able to recover a core

[timid plover]

searching for nrfutil rust comes up with interesting problems caused

[glad mortar]

happy to hear! People tend to be annoyed at west because they are not used to needing a framework specific CLI tool but it does so many nice things, I think one of the few things that actually make things easier rather than more complex

you can also extend it with project specific commands without forking west, could be potentially useful for some CPY specific stuff maybe?

like ' west repl' could be a thing

is the plan to eventually get rid of "ports" entirely or keep the structure and have a single port when everything is moved over?

but you could do dynamic pins in zephyr?

you can, just not de-init

de-init is outstanding

so you need to "reboot" atm to apply a runtime pin config

not sure what you meant with enumerate everything?
@ dynamic pin ctrl: https://docs.zephyrproject.org/apidoc/latest/group__pinctrl__interface__dynamic.html

[timid plover]

but ranting with good reason is acceptable!

[tulip canyon]

🔥 spicy

[glad mortar]

yea its so annoying with vendors, always need to provide loads of info and then you get spammed by them..

[eager matrix]

I was afk for a bit. I've started with Zephyr and am struggling to get over the hump. I'm quite familiar with RTOSs but the build system and the directory tree are taking me a while to wrap my mind around. Do you have any suggestions of way to get through this. Perhaps a tutorial or something. I'm not using the VSCode extension yet. Is this going to help?

[glad mortar]

@eager matrix what SoC are you working with?

[old surge]

Tonight on Deep Dives: 😋

[glad mortar]

the main issue with the Zephyr Docs is that they are quite spread out, they don't have a good red string to follow to learn all the things. When it comes to directory structure the west specific docs are fairly good starting point

@ de-init being outstanding https://github.com/zephyrproject-rtos/zephyr/issues/20012
thats the only part missing to do it without a restart as peripheral allocation is currently a fixed thing done once

but pins can be defined dynamically right now, which may already work for the CPY use case given you re-init whenever code is edited or?

[tulip canyon]

What shows with help("modules")

neat

[glad mortar]

yea pinctrl is very low level, def. something you want to wrap
I would recommend it over talking to registers directly though as so many other things that you probably don't want to actively manage are also handled via the same device subsystem that pinctrl ties into

[eager matrix]

A few. I'm looking to make Zephyr my go to RTOS rather then FreeRTOS, so I'm working to get a broad knowledge. Specificallty, I''ve got some audio things I want to do on a Daisy Seed which is STM. I also have a few ideas for ESP32. I also want to learn LVGL and I've got a couple ST Discovery boards that have displays and both have multiple but different cores (one is M7 + M4 and other is A7 + M4)

[glad mortar]

yea lvgl is integrated quite nicely, its not modified just a bit of shims to work with things like the display subsys

[eager matrix]

The LVGL demo wouldn't fit on the Wio Termimal. It bothered me that I couldn't find out what the symbol tables llok like and what was taking up some much data space.

[glad mortar]

you can generate a ROM and RAM report with west

https://docs.zephyrproject.org/latest/develop/optimizations/tools.html#build-target-rom-report

[eager matrix]

Thanks, that exactly what I'm looking for.

Probably I should take a deep look at everything west can do.

[timid plover]

so where is build_circuitpython.py getting the Zephyr information ?

and the device tree information is what you added earlier when you downloaded stuff from ST website

oh - so zephyr already knew about your board - and that is what you gain ( besides the netword chips for bluetooth and wifi )

[eager matrix]

I'm assuming that putting CPy on top of Zephyr is going to make it quite dissimilar to Micropython. What types of issues do you think this might cause?

[timid plover]

how is your time schedule today ?

[eager matrix]

You mentioned at the beginning that you folks aren't quite sure you are going forward with Zephyr. Did you speak to this while I was away?
