@timber mango I suspect that it is converted from the X Windows bitmap font 5x8, which would be in that same bdf format that @slender iron mentioned

@slender iron font5x8.bin is used in the Charlieplex libraries. Should this be converted to what everything else uses?

that would be my preference since bdf files support a larger variety of fonts

Hi all! Next week's meeting is just under a week away at its normal time, Monday...
Here is the circuitpython2020 recap: https://blog.adafruit.com/2020/02/03/circuitpython2020-recap/
tidal kiln
what's the general approach for doing a manual screen refresh with displayio?
manic glacierBOT
trim elm
@tidal kiln I think it's board.DISPLAY.refresh() but I'm not entirely sure
Although that's technically not through displayio
tidal kiln
yep. that's displayio.
i'm trying:
display.auto_refresh = False
# and then later
display.refresh()
works once, but then on second call getting:
RuntimeError: Below minimum frame rate
it's in a loop that has a several second delay
slender iron
refresh takes a minimum target frame rate
I think it you set it to 0 then it is disabled
looks
its meant to alert you if you expect your game to go at 15 fps for example
tidal kiln
ok. that's what i was thinking.
so i should set it to match the slowness of my loop?
this is a case of very slow updates - just every couple of secs
slender iron
I'm not sure it can go that low
ya, 0 disables it
minimum_frames_per_second = 0
target fps will slow you down if you go too fast
slender iron
hrm
tidal kiln
more info - i'm updating some text labels, both text and position, and trying to prevent the redraw until done with all that
slender iron
ah, you'll want to set the target frame rate really low too
if you are behind the target then it'll skip the update
it may crash if it is less than 1
tidal kiln
needs to be an int, set to 0. didn't crash, but didn't update.
stuck elbow
could there be a special case added for 0?
tidal kiln
display.auto_refresh = False
while True:
label_1.text = some_new_text
label_1.anchored_position = some_new_position
#
# do the same for several more labels
#
# and then manually refresh
display.refresh()
# and sleep
time.sleep(5)
that's the gist of it
slender iron
can you run it faster?
you could set target frame rate to 1 and it'll slow it down for you
no need for the sleep
tidal kiln
and just let it update the screen that fast? and update the other things at the slower rate?
slender iron
just let it update everything at that rate
tidal kiln
but don't want to have the label updates be that fast
it works without setting auto_refresh = False
but then you see all the labels get moved, and it's not a smooth screen update
slender iron
well auto_refresh off can't do multi-second frames
it assumed auto-refresh would work for that
so we can add support for 0 fps
tidal kiln
what @stuck elbow was suggesting?
onyx hinge
What if you set auto_refresh False while you're moving things around, and True when you're done and ready to sleep? That's sort of generally what I did in JEplayer when I wanted a bunch of UI elements to update at the same time.
(I didn't read back everything, apologies if I'm retreading something)
slender iron
@tidal kiln ya. @onyx hinge's suggestion could work too
tidal kiln
@onyx hinge awesome. yep. that works. thanks!
onyx hinge
@slender iron do you think that we're computing the huffman codes for ALL the strings in the message file, or JUST for the ones actually used in this board?
tidal kiln
while True:
display.auto_refresh = False
label_1.text = some_new_text
label_1.anchored_position = some_new_position
#
# do the same for several more labels
#
# and then manually refresh
display.auto_refresh = True
# and sleep
time.sleep(5)
it looks like it happens via the QSTR machinery which is based on what's actually enabled at the preprocessor level .. right?
serene warren
Hmmm. I took the "try:" from line 12 in the Weatherstation code.py file, which makes the new line 12 "from secrets import secrets" and the errors about line 8 and the pyportal stopped showing. But now the error for line 13 and the secrets.py has changed to line 13 in code.py which now reads "except ImportError:"
idle owl
I don't think you can have an except without a try.
serene warren
Thank you @idle owl , I tried commenting out the except and it went back to the old long list of errors.
tulip sleet
@stuck elbow pewpew_m4 has many native modules turned off, but not CIRCUITPY_ANALOGIO. Do you need analogio?
we're lookin' for space. pewpew_m4 zh_Latn_pinyin has 16 bytes free
stuck elbow
@tulip sleet I don't need it for games, but if someone wanted to connect a pot as an additional controller or something like that, they would need it. I know it's disproportionally large. I'm working on making the frozen modules smaller by not including the graphics in them for the final release.
tulip sleet
de_DE has 24 bytes free
i'm trying to decide what to do in the short run. Maybe I'll turn it off temporarily if you are going to continue to squeeze the library. The filesystem size could also be adjusted but you might want that as large as possible.
stuck elbow
@tulip sleet if you run out of space, turn CIRCUITPY_ANALOGIO off, and we can enable it if space becomes available
by the way, I asked at my fab if they would like to ship it also with Chinese firmware when the order is from China, and they told me that even children learning to program should know enough English to understand the error messages
tulip sleet
pl has 804 free; en has 1660 free. Yes I will do that for now so we can get the displayio color tuples pr in. thank you very much
FYI, saved 1420 bytes

I just got a CLUE today (!) I loaded CircuitPython 5.0 beta4, but it doesn't seem to be working. I see the blinka snake in the upper left, but nothing else on the screen. am I too much on the bleeding edge? (is this expected to work?)
idle owl
@raven canopy I should have. I found a conversation between us from 2018 where you said it was tickling something in your brain about automock, so I tried that. It worked.
@strange cargo It should work. Are you not getting the CIRCUITPY drive? because there was a bug causing that.
raven canopy
good candidate to add to the library guide's checklist?
raven canopy
hehe. that guide needs love anyway. Travis isn't the best place to test with anymore. 😄

@idle owl if I double-click reset, I get /media/pi/FTHR840BOOT , so I can load a uf2, but with 50-beta4 running I don't see a drive in /media/pi ... also I don't see the REPL connection. normally I would have /dev/ttyACM0 but I don't see that

idle owl
Ok try this firmware:
@strange cargo Load that onto the FTHR840BOOT drive.
Should resolve it if you're having the issue I think you are.
strange cargo
@idle owl thanks! I'll try that. I'm chatting on a different machine than I use for CP, so I'll need to transfer that file over (will take a bit). is that something that will show up as a fix in "beta 5"?
idle owl
Beta5 will be released tonight or tomorrow, and will have this fix in it. So when the next beta is released, download it from CircuitPython.org/downloads and use that instead. But this should get you going now.
Yes
strange cargo
great. thanks!

Is it expected for the reset button on the pybadge (or anything with built-in neopixels really) to keep the neopixels on showing whatever color was last set when the reset button is pressed?
slender iron
@lone axle what are you resetting into? they don't actually reset themselves with the button
but circuitpython should clear them for you
lone axle
I was in bootloader mode and they were green. I pressed reset and went back to normal and they stayed green
and stay green through subsequent reset presses
slender iron
try the latest build. I think dan improved it on circuitpython recently
the reset button doesn't reset the neopixels directly
lone axle
Ah, yep with the newest build they do get turned back off
slender iron

I have hit a new problem where I want to detect a switch press right now so it does not have to be held down. I know this yells "Use an interrupt," but Circuitpython does not have external interrupts. Is there another way I can handle this?
slender iron
have you tried polling? it can be pretty fast
timber mango
@slender iron I am not sure that is what I need. If that would that mean to check the switch every time through the loop, I do not think that is what I need. Is there something else that refers to?
timber mango
@slender iron That is not what I need then. I am doing a bunch of sensor stuff in my loop but want to add a switch to allow toggling the display on/off. As I see it, polling would still require the switch to be held down.
idle owl
@slender iron It's posted to a wip branch on my fork. I'll send you a link. Other than documentation and changing how the default colors are handled in the data display, it's pretty much what I'm going to PR.
slender iron
cool! thank you!
vapid shell
Clue with Arduino , video: works with Circuit Python too. https://youtu.be/ibOR9DR8LbU
timber mango
Also, when writing to the display, I can not poll the switch. I do not know if interrupts would work here either though.
tulip sleet
@timber mango the gamepad module could be helpful to you: https://circuitpython.readthedocs.io/en/latest/shared-bindings/gamepad/GamePad.html
it polls buttons in the background and remembers their state
timber mango
@tulip sleet Ah, OK, I will try that, thanks!
I am off to a nap, so will check out the gamepad module later.

@trim elm @slender iron I just put the most recent build of CP on my CLUE (pirate) and am now trying to test Dylan's code. It's just plugged in via micro USB, I It's show some strange behavior:

@slender iron @trim elm I've tried a few more times and sometimes the timing or order is different, but the end result is always that I end up in the raw REPL.. The big issue is that writing to the drive by saving an edit to code.py does not reload
@tulip sleet any insight you have would be useful as well
trim elm
Hmm. Have you tried using the uf2 that @tulip sleet made a few days ago. That’s what I’ve been working off of
pastel panther
@trim elm I don't think this is your doing, just keeping you in the loop
I have not
is it titled clue-PR-2571.uf2?
trim elm
Yup
pastel panther
I'll try it. Is/was master not working?
trim elm
It wasn’t. I wasn’t even able to get it to show up as a usb device although I haven’t tested the most recent build
pastel panther
ok, I'll try testing with that one.
hmm looks like the same behavior. I'm guessing by the name of that UF2 it was from a PR that has since been merged
I'll add the libs and keep testing
trim elm
Ok
And yeah, I think that’s the case. Based on the date of that uf2 from the website, it’s probably a very similar version if not almost exactly the same.
@pastel panther are you testing with a heart rate monitor?

I don't have another computer to try easily. I can pull the PC out of the closet if need be however, and I have an up to date ipad pro I might be able to test with if I have the right cable
tulip sleet
that is worse; it gets really confused by the .Trashes file
pastel panther
@tulip sleet cp -R
tulip sleet
cp -X will suppress copying the ._* files
pastel panther
that's good to know
raven canopy
has cp -R ever caused this before, though @pastel panther?
pastel panther
@tulip sleet possibly also relevant, one of the last times before I put the rest of the libs on the drive to get dylans code to run, it looked like I was getting phantom typing

@tulip sleet an update regarding the CLUE strangeness yesterday: I believe I reproduced it on a CP BLE though it's less certain because it doesn't have a screen to send REPL output to. I have pictures of the phantom typing I'm getting on the CLUE though I imagine I should probably open an issue

@onyx hinge terrific fast job on ulab. we could enable it on a bunch of boards (all nrf, maybe all m4?) How big is it?
onyx hinge
@tulip sleet about 35kB on clue I think
tulip sleet
REALLY, I thought it would like 100kB
I'd say let's enable it for m4 and nrf. this is a huge thing. I could include it in the beta

let me double check

"Huge" as in great

Latest(?) master: 535800 bytes free in flash firmware space out of 839680 bytes (820.0kB).
I will work on enabling it in m4 and nrf. I think SOME m4 boards will be close enough to capacity we'll have to back it out, but let's see.
tulip sleet

did you get in touch with Andrew Gatherer?
Also could add to the boards he is targeting (kicksat and whatever the other one is); i think they do not have external qspi

@pastel panther Soaked the usb port end of my clue in acetone and the usb port is now working again
pastel panther
that's good
idle owl
@trim elm When you said debacle, you meant it.
trim elm
ooohhh yeah. I got superglue and then acetone all over my desk
pastel panther
@trim elm ya, you're rivaling my ability to create problems that can only be solved by acetone or other similar strong solvents
pastel panther
lesson learned: putting acetone on a problem always fixes it
idle owl
@trim elm It was good timing on your part, I considered using super glue to fix my CLUE display.
At the moment there's a piece of twist tie tucked under the cable in the back that kind of shims the display down.
trim elm
I think that the gel super glue might actually work. The super glue I tried had turned completely liquid for whatever reason
Also, a bit of hot glue that is then filed down would probably work too
just on the edge
idle owl
Ah fair enough. There are super glues that are entirely liquid too.
I think it comes up enough for doublesided tape but I wasn't sure whether that would affect the functionality or not.
mine I mean, comes up enough for that.
Doublesided tape is mostly clear?
trim elm
hmm. I might try some on my pyportal that's having the same problem
onyx hinge
to affix the screen to the pcb? why would it be important to use a clear doublesided tape?
trim elm
To attach the screen to the metal part
onyx hinge
@tulip sleet metro m4 express 192148 bytes free -> 157124
tulip sleet
that's still very fine
idle owl
Isn't the backlight separate from the display? It was confusing to me when I peeled it up
I thought putting something not clear in there would block the backlight
but it's so bright with it on, I couldn't tell what was where
onyx hinge
if it's between the backlight and the lcd, for sure
trim elm
I can't open the screen on my clue, but on my pyportal pynt, it looks like you should be fine to put anything back there. I'm gonna test with just single sided tape
idle owl
I have a role of scotch doublesided tape somewhere around here.
trim elm
@idle owl Yeah, I think that if you tape the white part to the metal part it should be fine
onyx hinge
@tulip sleet there are ".rst" docs in ulab. any idea if/how we can slurp those in ?
idle owl
Fair enough @trim elm
trim elm
I think the issues happen when it gets in-between the white part and the rest of the screen
onyx hinge
oh should have used ulab.spectrum directly, not fft
@tulip sleet sadly, it doesn't fit on kicksat. /usr/bin/../lib/gcc/arm-none-eabi/9.2.1/../../../../arm-none-eabi/bin/ld: region `FLASH_FIRMWARE' overflowed by 16556 bytes

is ulab meant to be a subset of numpy?

"conforms to numpy as much as possible"; I don't have enough numpy experience to really say
meager fog
@onyx hinge can ya give me a CLUE uf2
onyx hinge
@meager fog yeah!
tulip sleet
it's a lot of work to shared-binding it, and we'd break pulling from upstream. I think that's a good long-term goal, and it can be done invisibly later
onyx hinge
tulip sleet
slender iron
just move the __init__.c across and document it
you don't need to worry about splitting the implementation
onyx hinge
I gotta go 🌮 but I'll be back
tulip sleet
@slender iron @onyx hinge it will be no worse than json and re are in their current form
slender iron
they should be improved too
I don't think its more than a days work to move everything around
tulip sleet
sure i agree with that
slender iron
the docs are already here: https://github.com/adafruit/circuitpython-ulab/blob/master/docs/manual/source/ulab.rst
tulip sleet
so can't we just link to the .rst instead of pulling it into __init__.c ?
slender iron
I'd rather not because the rst isn't structured well
functions aren't marked as such for example
tulip sleet
we can PR improvements back to upstream, but I don't think that should be a blocker to incorporating it. I'm worried about making changes now without a plan as to how to keep compatible with upstream
slender iron
I don't think it's useful until it is well documented
linking to their own read the docs leaves confusion about what version we have
tulip sleet
we have forked it, so we can link to our readthedoc
for the fork
i have used numpy. for someone familiar with numpy it is pretty well documented
slender iron
I'd rather just reformat the docs now so that it's done. having the shared-bindings document structure gets us much closer to generating stubs for IDEs as well
ionic elk
@slender iron @tulip sleet As I work on the core temp and VREF functions, I'm noticing that a VBAT read is kind of conspicuously absent. Is that something that's implemented elsewhere or just not priority?
slender iron
folks who haven't used numpy should be able to use it based on our docs
tulip sleet
we don't have to put it in the imminent beta.5
i'm not sure that's necessary, since we don't document core python stuff either; we refer people to the CPython doc
slender iron
we don't need ulab in beta.5 either
I don't want to rush it in
its not much work to get the docs in standard form
tulip sleet
i agree we could wait a bit. if we could pr the doc changes back to upstream that would be good
@ionic elk do you mean reading from the voltage divider?
slender iron
we do document the subsets of cpython modules we implement
tulip sleet
there are some python examples about how to read the VBAT voltage divider
with analogin
ionic elk
@tulip sleet no, from a dedicated VBAT pin. Which on looking, I guess the SAMDs don't have, so that answers that question.
Thought that was an ARM specification thing but I guess not.
tidal kiln
nah, it's just a voltage divider fed into an available ADC pin
and then i think convention is to name that pin VBAT
ionic elk
Yeah the STM32s have a bunch of register settings and stuff related to it so I thought it was more of a core feature.
I could add the functionality if desired, might be nice for battery using people.
onyx hinge
@slender iron I'll look at drafting documentation in our "style" in a __init__.c file, reusing text from ulab.rst where possible. That seemed to be the conclusion of the discussion?
tulip sleet
yes, i was chomping at the bit, but we can clean it up more first
onyx hinge
I like knowing that others are enthusiastic but there's no reason to hurry
slender iron
@onyx hinge that would be awesome. I don't think it's too much work so I think it is worth doing
consistency is very helpful
onyx hinge
Upstream docs are 3300 lines so.. I am not sure it will be instant
ionic elk
micropython veterans: do you know the difference between adc.c and machine_adc.c? They seem completely redundant.
tulip sleet
@ionic elk machine_whatever.c is probably for the machine native module. I don't know why there are two.
slender iron
@onyx hinge true. but hopefully faster than writing it yourself
onyx hinge
It's all good, I'll know the markup much better by the end too

fallen anvil
Hi folks, is this the right place to ask dumb questions about porting CircuitPython? Specifically mimxrt1021?
I'm whacking into a hardfault in flexspi_nor_flash_init but I don't really understand how the XIP is being handled while the FlexSPI is undergoing brain surgery in those routines. My board is losing it's marbles somewhere inside the flash init process. Unfortunately it's a custom board with the flash on the alternate pins (so no DQS available) otherwise I guess it would've come straight up.
timber mango
@fallen anvil I find that when working with something new, it is best to work with the standard configuration a bit before jumping into something super custom. This has saved me many headaches.
fallen anvil
I have the standard configuration working fine on a Teensy4, its the leap into the unknown thats got me fooled.
(Teensy4 is 1062, but it's close 🙂 )
timber mango
@fallen anvil Ah, OK. Those unknowns are where the fun really starts though! 🙂
fallen anvil
he he...tell me about it!
I just don't see anywhere where the XIP is switched off or otherwise accomodated while the flash is reconfigured. I guess I'm missing something, but I don't see what.
timber mango
Is there an example for the configuration you want to use that you can refer to?
fallen anvil
I'm starting from the 1021 config. There should really only be one thing to change (famous last words)..changing kFLEXSPI_ReadSampleClkLoopbackFromDqsPad to be kFLEXSPI_ReadSampleClkLoopbackInternally . Certainly that gets me booted and into running code, but then I hit a wall again when the flash comes to be reconfigured in the main startup code.
timber mango
I will not be any help there, sorry. I am just trying to point at things that have messed me up in the past, like not looking for examples. Sometimes, even within a family of parts there can be differences.
@fallen anvil @indigo wedge would be the one to talk to about i.mx rt stuff.
fallen anvil
Oh, there are certainly differences amongst this family! Thanks for trying. Hopefully we can leave this hanging here and if arturo has more info they can ping later. I'm just worried that it might be relying on the Instruction cache while the flash is reconfigured, which would be bad mojo....but I can't believe that's the case, I've just missed something somewhere.
timber mango
@tulip sleet Was it you who suggested the gamepad module to me yesterday?
Speaking of the gamepad library, are there any examples on how to expand use from one button to up to eight buttons? The one button example is a great starter, but it is difficult to figure from the docs how to expand that.
It does look like I will be able to use gamepad for all my switch related needs though. It works much better than I thought it would!
tulip sleet
@timber mango yes, it was me. @stuck elbow wrote the library. The constructor takes a variable number of arguments, so you just add one more arg for each button. See the example here: https://circuitpython.readthedocs.io/en/latest/shared-bindings/gamepad/GamePad.html
timber mango
That is the example I used to get it implemented into my script, since I am just using one button right now. But, how would I check for the second or third buttons? That is not clear to me at all.
At least now, I will not have to reconfigure and restart my script when I go to bed. I can just toggle the display off. 🙂
Bye for now. I will return later.
slender iron
@fallen anvil ideally we wouldn't reinit the flexspi at all and rely on the boot rom to get it going
fallen anvil
Hiya. Yes, thats what I've done now, and it's working fine. Not sure why it's being reconfigured in the setup code, which is what I really wanted to ask about
There doesn't seem to be any provision for preventing XIP doing a fetch from the Flash while its being reconfigured, which isn't a good thing, if my understanding is correct.
slender iron
ya, that is my understanding too
I believe those flash functions are placed in ram though
so as long as interrupts are off it should be fine
fallen anvil
Then I think we'd better clean it up, but I don't want to go blundering through someone elses codebase making changes and submitting patches without some discussion first to make sure I understand.
For me, at least, those routines are in flash. Perhaps I banjaxed the linker, I'll check...getting late here now.
slender iron
I'm happy to discuss it. I'd love to see another person working on imx
I redid the linker stuff
to get the TCMs going
fallen anvil
I've spent a long time on imxrt, did a fair bit of work bringing NuttX up on it. Would be nice to see this running well.
fallen anvil
I have a custom board with a fair few perhiperals which can be open sourced if its useful to anyone....CAN, Ethernet, RS485, RS232, RTC, SD Card, ADC, WiFi and a Pi expansion header.
slender iron
we'd be happy to have the code for it in circuitpython and having schematics would be nice to have too
fallen anvil
you can have the KiCad if it's useful...what goes around comes around
slender iron
nice!! very cool
I'm in seattle and will try to respond to you early tomorrow in case you want to sync up
feel free to pr any code changes you have
fallen anvil
OK. I'm UK so on GMT at the moment. Will try and sort this out now I have some idea where it's at. I propose to move the flash configuration into the boot_hdr.conf section and away from mainline code, which also serves to solve my other problem that I don't have DQS available on my board....but let's see how tomorrow goes.

idle owl
Haven't gotten this one before: You are in safe mode: something unanticipated happened. CircuitPython core code crashed hard. Whoops! Nordic Soft Device failure assertion.
slender iron
@onyx hinge if only it was running 90 degrees to that and we actually used the display's scroll
onyx hinge
@slender iron I can tell you are already working on displayio 2.0 in your head
slender iron
there are always things I want to do
I think the next display thing will be supporting 24bit output peripherals and bigger screens
onyx hinge
it seems like a real challenge getting good framerates and memory usage for so many different use cases
I'm starting to appreciate that fact more the more time I spend with it
onyx hinge
the way the original scrolling style display was coded I think gets a "wow clever", but it does not hit a fast case for the refresh code. It makes a TileGrid where each row of the screen is one tile. So to scroll, you just reassign the tile indices. But of couse behind the screen it becomes necessary to refresh the whole screen.
slender iron
the displays are designed to scroll in one direction
we just don't take advantage of it
onyx hinge
to change a row content you assign to the bitmap, but I think that also causes the whole containing TileGrid to be redrawn, so the fast non-scrolling version uses a bitmap where there's 1 pixel with each value 0..len(palette)-1 and you assign the TileGrid elements to change the display. That's the most performant way I came up with
no general bitblt in the LCD controllers yet? 🙁
slender iron
the tilegrid should have a fast path for updating a rectangle over the pixels you've changed
onyx hinge
when I assign tile grid elements like grid[x,y] = 37
I agree, that's what I think I see happening
slender iron
that should keep a bounds of the tiles updated
there is a fast path for a tilegrid with a single bitmap
onyx hinge
what I think the original fft demo was doing was assigning bitmap[x,y]
should that be a fast path too, and maybe I'm mistaken in what I thought I was seeing?
slender iron
editing the bitmap should only cause the damaged area to update
onyx hinge
in the case where the whole TileGrid is 1 tile only? This is 1x120 tiles (WxH) or something
I didn't test the 1x1 tiles + assign to bitmap[x,y] case
slender iron
right, 1x1 tiles
onyx hinge
ok
onyx hinge
yes, that scrolls fast too. Thanks for the tips!
that's the more "natural" way to do it?
slender iron
¯_(ツ)_/¯
meager fog
@onyx hinge yeah not scrolling is what i recommend
@onyx hinge do you want to gimme new code
onyx hinge
jas!
if you really want the slow mode, you can hold down the A button while turning on / resetting
probably should just remove the scrolling version entirely
meager fog
yeah i dont think its necessary
like there's no strong UI need for scrolling
you found that its fastest to do with tilemaps instead of assigning bitmap elements?
onyx hinge
not exactly
there was a combination of using tilemap + assigning bitmap elements that was just as slow as scrolling
so we won't use that one
scott didn't seem to care which of 2 fast ways of updating a row at a time I used
they seem about the same speed. to me, the one which modifies the bitmap makes a bit more sense.

Apropos of nothing; I recently had to manually set a TIM3 interrupt on the stm32f407 and found out that the APB1 clock is 42 MHz except when the TIM3 prescaler is not 1, then it's 84 MHz.... Had me searching for a while. (Same for every timer on apb1.)
raven canopy
@slender iron for the calls to the API, yes. its the access_token query string that is now deprecated. it needs to be changed to use the HTTP Authorization header. it lies in the github_requests.py function, from when i looked last night when Kattni pointed it out to me. i plan on working it here in a few; i'm playing hookey today. 😄
slender iron
@raven canopy cool thanks! go back to hookey 🙂
raven canopy
hookey days are spent writing code! usually. 😉
ionic elk
@timber mango that sounds like the item documented in the PWMOut.c file in the ST port:
// If the APB prescaler is 1, then the timer clock is equal to its respective
// APB clock. Otherwise (APB prescaler > 1) the timer clock is twice its
// respective APB clock. See DM00031020 Rev 4, page 115.
But it sounds like you're talking about the Timer prescaler, which is confusing?
timber mango
@ionic elk Ah ok, nice. Yeah i found it in the reference manual.
Oh! Errrr, yeah timer prescaler i thought.
ionic elk
I try to document weird stuff like this in the code itself! Or carry it over in cases where Micropython made note of it, as in this case
So it's probably a good idea to go check out the module c file first, before diving too deep. There might be an explanation right there in the code.
ST has LOTS of weird little cases like this.

Is there any way to reset a pin from circuitpython itself? I was typing a reply to that issue and realized that I don't think any of those functions are actually exposed.
lone axle
reset a pin like deinit?
ionic elk
Can you de-init a pin without it being part of anything?
slender iron
all pins should be deinit before the VM runs unless it is used by the supervisor
ionic elk
@slender iron the question is whether you can manually remove a pin from never_reset from circuitpython itself
ionic elk
Is that something that's a hazard to add? I've also sometimes wanted that functionality, to manually release a pin when it was claimed by something I didn't want enabled.
slender iron
you shouldn't need it
ionic elk
The above case is reclaiming a SWD pin, for instance
which is added to Never Reset at startup and cannot be released
slender iron
protecting SWD is intentional because debugging is much more difficult if it is used
ionic elk
this effect would go away on reset, though, no?
slender iron
yes but only until the code reclaims it again
ionic elk
Well, if you're sure, I'll tell this guy there are no plans to add it
slender iron
I can reply too. the better response is pointing them to where its done and suggesting they compile it themselves

I think @onyx hinge already has 🙂

@arctic dome Hi! I was about to step away, but I'd be happy to share my code with you before I go.
and thanks for the original version, it was really easy to build on top of
arctic dome
Ya thanks!
ionic elk
@slender iron I'm not sure where atmel even disables the SWD pins so I guess I've got to defer that one to you
slender iron
kk, I'll reply tomorrow when I circle back to email
I think it's a function of the pinmux
onyx hinge
@arctic dome you are Thomas S. ?
arctic dome
Ya
onyx hinge
okay, didn't know your Discord handle
arctic dome
Same as twitter

It's time to do some cooking but if you mention me I'll be sure to read it. ttyl!

@slender iron I would bring last_temperature=temp under the if.
slender iron
@timber mango why?

Only needs updating if different

When we are mentioned and we are no here, how do we get the mentions when we come back?
idle owl
@timber mango For the most part, you have to scroll back to find it. However, the search function has a mentions: option which means you can search for mentions:geekguy with your full handle, and it should bring up the messages.
timber mango
@idle owl Oh, OK, thanks!

Here is a more complex sensor (Clue): https://gist.github.com/tannewt/a471dfa780617b0973a32f19bb727e90

@timber mango on the desktop client there's an "@" in the upper right corner, clicking that should get you your mentions

@slender iron nice sensor node - could also try kattni's lovely new library, would save ya some init's 🙂

While working on the electronics for my Little Red Rover, I realized that I have the starting point of other possible projects, including a NEST-type thermostat, and even a master for a home control system.
I have not figured out how an IMU could be useful in that though. 😃 😉
Will there ever be a Bluetooth module that will work with any Express or other board and Circuitpython?
ionic elk
@meager fog @slender iron could we connect on priorities at some point this week? I've got the Espruinos on my list but beyond that it's kind of open - could do QSPI, flash improvements, PulseIO, audio, etc.
meager fog
yep how about tomorrow?
ionic elk
sure
meager fog
ok when scott's around we can figure out a time - afternoon ET is best for me
timber mango
Drat! An M0 Express does not have enough memory to use the ESP32-WIFI FeatherWing.
half sedge
Doc sometimes say "no M0" and sometimes say "M4 or nRF52840". But that was before so many more board were added...
meager fog
timber mango
@meager fog Now, I am going to have to solder stacking headers on my other Feather M4.
meager fog
For CircuitPython use, a Feather M4 or nRF52840 works best - the M0 series does not have enough RAM in CircuitPython.
geek, you could use a doubler
timber mango
@meager fog I know. That is why I am only buying M4 boards or later ones now.

@timber mango @idle owl you can also click this to see a summary of mentions
timber mango
Thanks @split ocean!
Is there a way to find out how much memory a script and loaded libraries are using?
idle owl
@split ocean Yeah Jeff pointed that out too. I was entirely unaware of that. Thanks to you as well.

@split ocean ah, I didn't know about the @!
@meager fog @ionic elk I'm around tomorrow except for lunch with a friend 11:45 - 1:30 pacific.

@gilded cradle Is CircuitPython_Display_Shapes in a usable state? I thought I remembered it being WIP.
gilded cradle
As far as I know it is. There's only a few shapes right now and it should be stable, but maybe the WIP idea was because there had been discussion of adding more.
idle owl
Fair enough. I need circles. Looks like it has circles.
gilded cradle
yep
idle owl
Ok right on, thanks. I will probably be pinging you with questions.
gilded cradle

I used on on an Edge Badge a few months back to make a simple pong implementation. I didn't run into any trouble with it.
idle owl
Nice, thanks for the confirmation.
half sedge
@idle owl Hi, I just found kattni_debug_i2c.mpy in the bundle, not sure this is "normal".
idle owl
@half sedge It's probably not. Means it got added from the wrong submodule.
I'll look into it.
ionic elk
@slender iron @meager fog 10am or 2pm would work well for me tomorrow, but anytime is fine, really.
idle owl
@half sedge Thank you for catching it - it was accidentally included in a new lib, and therefore included in the bundle. Should be resolved in the next couple of days.
slender iron
@tulip sleet nrf i2c on clue isn't working for me with a master build
slender iron
OSError: [Errno 5] Input/output error```limor and i noticed flakiness earlier; we are still debugging it;
slender iron
kk
slender iron
@tulip sleet how can I disable the default scan response? the SD can't do extended advertising with scan response
tulip sleet
you mean disable via SD API or in the library?
i don't know the answer to either off the bat
slender iron
I was thinking the library. I can modify the library so it doesn't do it for extended advertisements
ok, got it
tulip sleet
ok great

Thank you to all of #circuitpython-dev for your help with all the XAC and other AT projects... this video shows LOTS of your code being used in great ways! https://youtu.be/bdDb-l_-ZYw

@slender iron I hate that Error 5! I have found that it is often a bogus error and after pressing Ctrl/D to restart enough times the script will start running perfectly.
Is there a way, from inside a running script, to find out how much memory it is using?
slender iron
if that is on nrf then it sounds like dan is on the trail
there is a gc module
and it has gc.mem_free()
it doesn't account for fragmentation though
timber mango
I get that error 5 a lot.
slender iron
on nrf?
slender iron
hrm. I haven't seen it there. are some sensors worse than others?
timber mango
I get error 5 no matter what I am working with. I just keep restarting the script until it starts running normally. It really annoys me and breaks my flow.
Sometimes, I do have to wiggle a sensor though, like the vl53l0x which I get it on a lot.
slender iron
hrm, weird
timber mango
The vl53l0x is the only sensor I have where error 5 has been valid.
Very weird.
Now is a good example. I just saved a script to CIRCUITPY as main.py, it restarted, and here comes error 5 right away. 😫 The script will run fine after I restart it enough times.

lone axle
the clue library made it super easy to convert gizmo thermometer for use with CLUE. Excited to play with the rest of the sensors.
timber mango
@lone axle I so want a couple of the CLUE boards, but I will wait until they are in a full production versions. I see many possibilities!
lone axle
I couldn't resist the chance to play with it
timber mango
OK, time for me to heat up my soldering station and put some stacking headers on my other Feather M4 Express. I want to play with the ESP32SPI WiFi Featherwing.
@lone axle That little CLUE would be hard to resist for tinkering!
lone axle
@onyx hinge after poking around a bit more with a more isolated example I'm less sure about the nature of the issue I mentioned yesterday being as simple as voice 0 vs voice 1 on beta4 vs beta5. I'll do some more testing on some other devices and create an issue if needed when I understand it better.
timber mango
Well, bummer, it appears that I did damage my AirLift FeatherWing when I soldered the stacking headers on to it. Oh well, I had to try.
I really hate soldering headers on to Feather and FeatherWing boards! I may have to stop buying feathers because I keep messing them up and can not afford to replace them. 😫
tulip sleet
@timber mango if you post good pictures of your soldering (especially the bottom of the board if you're using stacking headers) on the forum, our experienced support folks can make suggestions about your soldering and whether it might be recoverable.
also describe your soldering setup
timber mango
@tulip sleet I do not think suggestions would help. I know how to solder, but my eyes just can not handle the close together pins on the stacking headers. I do fine when soldering to breakout boards.
tulip sleet
do you have a good magnifier or is it a matter of steady hands? I use an Opti-Visor when soldering: https://www.amazon.com/Donegan-OptiVisor-Headband-Magnifier-Magnification/dp/B0015IN8J6
timber mango
I do not have any magnifier. I wish I did. I am sure that would help a LOT once I got used to working with it and soldering.
tulip sleet
i have to use it when plugging in breadboard jumpers too.
A cheap pair of strong reading glasses (like +2.50) would work too.
there are visor like that that are less expensive. I am old enough that I have presbyopia, and need several different strengths of reading glasses. Further than 6 feet away or so I'm better than 20/20, but not close up.
timber mango
That magnifier really looks nice, and it would probably work with my glasses. I will put one on my want list. Yeah, plugging in breadboard jumpers gets me frustrated too sometimes.
tulip sleet
our local job lots store has reading glasses for like $3.99.
tulip sleet
I wear the visor over my reading glasses.
I have doubled up reading glasses in an emergency. Anyway, give yourself a present for these. They will help a lot for many things (e.g. removing splinters, sewing, reading fine print).
timber mango
Cool. That is the way I want to go. I prefer the hands free approach.
tulip sleet
i have a desk swing lamp with a big lens and surrounding light, but I prefer the visor, because it moves with me.
timber mango
The good news is that it appears I did NOT damage the Feather M4 Express I soldered tonight.
That is why I would prefer the visor, plus hands free.
I still wish Adafruit offered ALL Feather boards and Wings with headers already soldered on, but that would probably be a bit of a nightmare.
tulip sleet
@slender iron FYI, MicroPython discussing auto-formatting of C code to enforce style: https://github.com/micropython/micropython/issues/4223 was reopened
wind trellis
#if (MODULE_ULAB_ENABLED)```Where am I supposed to define that?
I've tried mpconfigport.h and also boards\pyportal\mpconfigboard.h but neither of them work for me.
tulip sleet
@wind trellis are you trying to build the PR?
wind trellis
Trying to build from the circuitpython-ulab repository. Is that the PR?
Is there an issue with better instructions in it?
tulip sleet
no, that is just the library. It is a submodule used inside adafruit/circuitpython
@wind trellis you want to build from jepler's PR here: https://github.com/adafruit/circuitpython/pull/2583
but it's still in process; he's improving the documentation. We can probably merge it in a day or two.
@timber mango we added a placeholder
timber mango
what do you mean?
tulip sleet
still awaiting info from the board designer
timber mango
👍
wind trellis
OK, thanks @tulip sleet. I'll try cloning that.
tulip sleet
I just mean we added it so it can be downloaded, but we are awaiting images, feature lists, etc.
wind trellis
Yay, success cloning and building ulab. Thanks again @tulip sleet. It's running now on my Pyportal and I'm logging the deltas I see vs real Numpy. Is there a preferred place for collecting them?
slender iron
Thanks @tulip sleet I’ll chime in tomorrow. I think jimmo and I have the same sensibilities since we’re both ex google.

@wind trellis you can attach them to our PR to add ulab. But I'm not sure how many we will address over time.
@wind trellis if you find places where ulab-micropython and numpy match, but ulab-circuitpython differs definitely report that to us
idle owl
@lone axle When you put in a PR, since you have write access to the library repos, please request a review from CircuitPythonLibrarians using the review request link on the right side of the page. That way it notifies the review team. Otherwise, it can get missed. Thanks!
@onyx hinge How solid is your displayio
onyx hinge
Nothing expert. Want me to take a look at something anyway? I do have a meeting to leave for in 10 minute though
idle owl
It's a quick question that you may or may not have an answer to
Do you have any idea how to decide how big to make the group max_size?
I make it a number, sometimes it fails group full so I increase it arbitrarily, but I have no idea how to really determine that
onyx hinge
hmmm
if you can exactly count the number of items you'll insert, then you could pick that number
sounds like that's not feasible
idle owl
I don't know what items means though. Because I don't think it's related to the number of things you append to it
onyx hinge
(insert? add? append? whatever we called that method)
what's the traceback look like when you get the message?
idle owl
I haven't gotten it in a while, so I'm not sure
let me decrease it and get a traceback
Not exactly useful: code.py output: Traceback (most recent call last): File "code.py", line 17, in <module> RuntimeError: Group full
onyx hinge
is it your "main group", or is it happening say when you are updating a label text? those are also size limited and might give the same message when you send a label that is too long (max_glyphs of Label) .. but no, that's not it
idle owl
fails on the third append, with a group max_size of 2.
onyx hinge
that at least makes sense
idle owl
This is main group, but I'm appending shapes this time
