argh. that default to stable snuck in there (3.x)

obsidian dome
#

Hmm. I thought things like audioio were excluded for space reasons. I'd like to use a trinket_m0 to play sounds based on a touchio trigger.

ancient sage
#

How would you go about finding the memory size of objects in CircuitPython? sys.getsizeof seems not to be implemented

solar whale
#

@gilded cradle FYI -- with pr_1564 my the featherwing_rtc_simpletest runs with out error on my Particle_Argon!

raven canopy
#

@obsidian dome audioio is not included with a Trinket, since it is not a SAMD Express board. Express is when the board has external flash storage.

obsidian dome
#

@raven canopy so this would be a no-go to get the trinket to play audio out the analog port?

manic glacierBOT
raven canopy
#

@obsidian dome well, you can but you'll have to remove other things from the build to make space.

obsidian dome
#

@raven canopy That's why I was looking for what was in the Trinket_m0 build: Most of it I won't need for my project.

raven canopy
#

that part has just changed significantly, so i wouldn't be able to help off the top of my head. still learning it myself. 😄

tulip sleet
#

@raven canopy would you be willing to go ahead and approve PR #1560? I know Scott is interested too, but I'd like to get the builds working again with all the current PR's. We can always change it later. Thanks.

raven canopy
#

i can. i told Scott last night that i'd leave it for him, but that list is growing. 😄

obsidian dome
#

@raven canopy Understood. Thanks anyway.

manic glacierBOT
raven canopy

🤞

#

well, that looks like it broke through the barrier... 🎉

#

and of course. fails 2 seconds after i type that...

#

CPX unhappy. 😦

tulip sleet
#

which build?

#

2573.1?

raven canopy
#

yeah. .2 is failing all the boards too.

#

all on mp_module_io

#

well, the weak links for it

tulip sleet
#

i'll work on it. I think it's all the atmel-samd builds. But this is why I wanted it merged. It's not the travis fix that's failing, it's the other PR's. Now I can actually test the new PR's comprehensively.

raven canopy
#

yep. net success!

tulip sleet
#

it's the small m0 builds that are failing

raven canopy
#

well, gemma just passed. 🤷

tulip sleet
#

?? well, I know which ones to test

gilded cradle
#

Thanks for the update @solar whale

obsidian dome
#

I just updated a trinket_m0, and now I am getting an error that I have "Incompatible .mpy file" when doing "from adafruit_hid.keyboard import Keyboard". I suspect I need new versions of the contents of the "lib" folder. This didn't seem to be a part of the firmware. Alternatively, where do I get the new default "main.py" for the board?

gilded cradle
#

As for the main.py, that's just the script that runs automatically when you start it up. I would suggest just using code.py though as that's the standard for adafruit boards. main.py was originally intended just for backwards compatiblity with micropython.

#

By script that starts automatically, I mean the program that you are writing that you want to run.

obsidian dome
#

There is a "default" version of "code.py" (or "main.py") that ships with most boards.
Given the amount of trouble I am having with my "upgraded" trinket, I am trying to start as "clean" and "simple" as possible.

gilded cradle
#

Yeah, I always blank mine out to start with.

obsidian dome
#

currently dying on "aout = AnalogOut(board.D1)"

#

reported error is "OSError: [Errno 5] Input/output error"

gilded cradle
#

Let me see which one that uses...

obsidian dome
#

I do have "import board" and "from analogio import AnalogOut, AnalogIn" prior to that.

gilded cradle
#

I think you also need import analogio

#

oh nevermind

#

Perhaps that got trimmed out?

obsidian dome
#

trimmed?

gilded cradle
#

From what I understand from above comments is you build CP from sources and added audio in there, but had to trim out some stuff that wasn't relevant to your project.

obsidian dome
#

I didn't do any trimming (yet). Just a stock build for the trinket_m0.

gilded cradle
#

Oh nevermind. I see the error. D1 is a digital pin

solar whale
gilded cradle
#

Oh yeah. I haven't really played much with the trinket. Do you have any ideas @solar whale?

solar whale
#

no - and no promises taht file will run with current release -- I'll try it

obsidian dome
#

Hmmm. Now that "main.py" complains "ImportError: no module named 'dotstar'"

solar whale
#

you'll neeed to put adafruit_dotstar.mpy in /lib

obsidian dome
#

It is there

solar whale
#

yes -- clearly the main.py is no longer valid 😉

#

let me try a few things -- it'll take a few minutes to get mine set up

obsidian dome
#

sure. I appreciate any help.

gilded cradle
#

Yeah, I just plugged mine in too

#

Which version of circuitpython are you now running?

obsidian dome
#

built "master" this evening.

gilded cradle
#

Ok, let me do that real quick...

solar whale
#

had to copy neopixel.mpy to the board as well

#

modify import and call to adafruit_dotstar

gilded cradle
#

Yeah, I saw that it had a different name too

solar whale
#

actually my build is with pr_1564

#

but should not matter

obsidian dome
#

This produces an error on line 25 "OSError: [Errno 5] Input/output error"

#

Your code ran on my trinket_m0 running CircuitPython 3 though

#

Only the one upgraded fails.

solar whale
#

hmmm -- ok -- maybey PR 1564 did fix something

#

I think it has been merged so try updating to current master and rebuild

obsidian dome

interesting issue that it fails after a soft reboot

Weird. IF I unplug the board, when I plug in again MU shows the print statements running. If I load the code into MU and save, I get the error on line 25 again.

gilded cradle

Yeah, I'm getting the line 25 error after soft reset as well. Might be a bug?

it works after hard reset

gilded cradle

Oh, ok

tulip sleet
#

@gilded cradle They do have a DAC, but I think we omitted the code for space reasons.

gilded cradle
#

Ah, and compiling ourselves got around that?

tulip sleet

oh, maybe not

solar whale

but why would it work after hard reset, but not soft

gilded cradle

Maybe something to do with stack size?

Hey, give me something to type and I'll test it 😃

how did you add audioio to the build?

I haven't.

I'll create a simple test script -- just a sec.

The only thing I can think of is my /lib contents came from adafruit-circuitpython-bundle-4.x-mpy-20190216.zip If this is incompatible....

gilded cradle

That's the right one. Mine came from the same

obsidian dome
#

But all three of us have the bug

gilded cradle
#

Yeah, but I think the bug is in CircuitPython itself.

obsidian dome
#

Understood. Just out of curiosity, how would I build the contents of that zip file from sources?

gilded cradle
#

It's an automated build, but to create an mpy, I believe you use mpy-cross.

obsidian dome
#

@gilded cradle Is that a build target somewhere in the source tree?

solar whale
#

yes just run mpy-cross sourcefile.py --it creates sourcefile.mpy

gilded cradle
#

It has a list of the CircuitPython Library repos and builds once a day if there were any changes.

solar whale
#

you will need to specify the full path to mpy-cross

raven canopy
#

you can also download a compiled version of mpy-cross from the releases. they're sprinkled in.

#

oh. nvm. we don't have one up for 4.x yet. 😦

solar whale
#

its the same as 3.x

obsidian dome
#

So looking at just neopixel, is this in: frozen/Adafruit_CircuitPython_NeoPixel/neopixel.py This makes me remember something about stuff migrating from /lib to /frozen. I don't know if that is relevant.

raven canopy
#

does it work? i know it has version checking, but couldn't remember if we're past that at the moment.

solar whale
#

the mpy format has not changed

raven canopy
#

and i really wish we could get travis to build mpy-cross for the releases. which, i'm sure we can. at least for the 3 OSes that are currently supported.

solar whale
#

it changed from 2.x to 3.x but has not changed since

raven canopy
#

k.

obsidian dome
#

roger that.

solar whale

but not a bad idea to regenrate it occasionally 😉

raven canopy

ahh. forgot about the Raspbian version. can't get that on Travis. 😆

solar whale

@obsidian dome has the repo cloned and built so it in in his mpy-cross directory already

[adafruit/circuitpython] Pull request opened: #1566 correct weak module links; samd module only in m4 ports; update frozen libs
  • Fix build issues on certain M0 ports.
  • Due to increased size of ure, turn on samd module only in m4 ports (was part of #1544, then got undone by #1554).
  • Update all frozen libraries (one didn't have a tag, so time to update anyway).
  • Make it clearer how to list weakly linked native modules that can be overridden, and how they have alternate names. (Now I think I really understand this properly.)

there's no bitbangio uart?

#

where will I steal code from now?

pastel panther
#

hmm... I thought he had samd51 code as well; I guess not.

exotic pumice
#

doesn't look bitbang-y

pastel panther
#

same54 is very close to the samd51 for what it's worth

#

why bitbang?

exotic pumice
#

because I'm making a bitbang library

#

similar to bitbangio

#

not sure if my logic analyzer has really fault-tolerant uart decoding or if my signal is ok

manic glacierBOT
exotic pumice
#

seems to be the former

#

actually, it's sending 10 bits, right?

#

so 943.4Hz is pretty close to 9600 baud I guess

#

I was thinking it was 8 bits

#

1.73% off, I'll take it

exotic pumice

it gets worse if I try 115200 😬

@weary raven What does "FS" stand for here?

manic glacierBOT
tulip sleet
#

the python files need to be stored somewhere. Do you mean not visible as a USB drive, or ?

#

no, we don't have anything like that (and neither does Python, really, as far as a I know). The average user needs libraries, etc. so they have to live somewhere.

I understand it from the point of view, of, say, how Smalltalk works, but that's just not hte model here.

[adafruit/circuitpython] New comment on pull request #1566: correct weak module links; samd module only in m4 ports; update frozen libs

Up until your changes io and re were weak links on M4 and not available on the others (only as uio and ure). I have relied on this to add a bit of functionality to these as well.

Ideally I would like all CPython std module names to be weak links and an underscore version being the C module. I don't think any of the C modules cover all the CPython functionality, so they all need to be extended to achieve CPython compatibility.

I saw that the new PyBoard will have ...

[adafruit/circuitpython] New comment on pull request #1566: correct weak module links; samd module only in m4 ports; update frozen libs

@notro How is MPy doing this? Would your sort of library completion work there? Do they have the equivalent of the _ version?

I'm a little concerned that listing a lot of _ versions will increase support issues. Is there a way not to do that, and have you import the original C module first, rename it, and then define yours? I'm not thinking very hard about this, so I may be missing somethign obvious.

@solar whale I only see your reply to the ESP32 thread. Was there a response that was deleted?

I'm going to discuss the u... versions of the modules with the other team members later today, to see what we might do going forward about dropped the u... names. We seem to be going in the opposite direction from MicroPython: https://github.com/micropython/micropython/issues/4370.

If you look at mp_builtin___import__ you see that as a last resort it looks at the weak links (aliases) before giving up. So if time exists in the search path it is loaded, if not the one in mp_builtin_module_weak_links_map is used.

MicroPython uses u as a prefix for the modules that exist in the standard library. @tannewt wanted us to use _ instead to differentiate from MicroPython.

is it planned in the far future to have BT5 mesh functionality using (future) circuitpyhon with the Adafruit Feather nRF52840 Express ? ,
or is it possible to have a BT "star"-topology network with one central and several BT clients (all of them nRF52840 based) ?

[adafruit/circuitpython] New comment on pull request #1566: correct weak module links; samd module only in m4 ports; update frozen libs

Maybe something like this could be used to handle the standard library module aliases:


#if CIRCUITPY_TIME
extern const struct _mp_obj_module_t time_module;
#define TIME_MODULE(name)      { MP_OBJ_NEW_QSTR(name), (mp_obj_t)&time_module },
#else
#define TIME_MODULE(name)
#endif


#define CIRCUITPY_MODULES \
    ANALOGIO_MODULE \
    ...

    IO_MODULE(MP_QSTR_##prefix##io) \
    OS_MODULE(MP_QSTR_##prefix##os) \

@gilded cradle Q: Does the returned response have an associated HTTP error code?

#

or does it just get serialized into json

gilded cradle
#

The response is an object that is returned it has a function to format it in json, but doesn't appear to have error functions.

prime flower
#

like - response.status would return the error code, similarly to the cpython library

gilded cradle
#

You can look at it in the adafruit_esp32spi_requests.py file

prime flower
#

Yeah, I'll dig a bit deeper, it'd be nice to have a way to handle and return the status codes

#

i.e: When you GET a feed from IO which doesn't exist, it'll return {'error': "not found - There is no feed with the key 'test'. You can create one using the feed creation API https://io.adafruit.com/api/docs/#operation/createFeed or at https://io.adafruit.com//feeds"}, but also a status code

gilded cradle
#

yeah, hopefully that doesn't require a big rewrite from the way it's doing it now.

@idle owl I'm trying to figure out a name for the Adafruit IO CircuitPython library I'm writing. Using the pre-existing naming scheme would make it Adafruit_CircuitPython_AdafruitIO. I think that sounds strange... Any suggestions?

idle owl
#

I think that's fine, it's clear and not confusing. I realise it's redundant, but redundancy in the interest of clarity is fine. You could also consider Adafruit_CircuitPython_AIO.

prime flower
#

_AIO would omit the AdafruitIO text, I'd like to keep that. How about Adafruit_CircuitPython_Adafruit_IO?

idle owl
#

Either way is fine. I think it works better without the underscore though.

prime flower
#

Agreed. Easier to type too. Thanks for the input!

Adafruit IO…wait for it…on CIRCUITPYTHON…OVER WIFI!
Building it out, it’s a wrapper on top of the ESP32SPI library’s WiFiManager class. Lots of things are breaking, but shouldn’t by Thursday. Been testing using a PyPortal, would love to have other hardware testing it

The majority of CircuitPython effort this week was put into generalizing and adapting an analog signal quantizing helper that I’ve used to turn variable potentiometer signals into indexed rotary-switch-like values. The helper uses direction sensing to apply a variable hysteresis value to minimize the noise created when the potentiometer value is sitting on a threshold value shelf.
The result of the effort is a range_index class that supports multiple instances of the algorithm depending on the range of the input signal and the number of output index positions/values needed. It can handle analog signals for uses like the potentiometer switch application, but also for processing Eurorack control voltage signals, providing linear quantization, but also inversion, compression, and expansion.
The range_index library passed all the tests so far, but I want to exercise some extreme conditions before calling it “good.” The conceptual design of the hardware implementation is done, so after testing, I’ll wrap up a PCB design and build the front panel.

Last Week:

  • adabot - library report:

    • Fixed core insights (issues, PRs).
    • Fixed RTD version fetching.
    • Changed downloads by board/language section to a table.

  • Libraries RTD:

    • Moved the drivers.rst file/content from the core repo to the Bundle, and setup Travis to build the docs.
    • Updated the drivers page in the core to point to the new location on the Bundle.
    • Updated "creating/sharing a library in the bundle" guide to include adding new documentation link to the list.

  • FrequencyIn:

    • Brought my seriously out of date branch up to date, and started re-gluing things in.
    • Moving from pulseio to a new frequencyio to allow for better port/board inclusion.

  • samd-peripherals:

    • Re-submitted previously reverted work to move shared_timer_handler() back to ports/atmel-samd dir. PR to finish on the core is ready to go once I can update the submodule.

This Week:

  • FrequencyIn

    • Finish re-gluing, run a few more tests, then get ready for PR.

  • adabot:

    • Work on newline issue for Google Docs transcription (I keep forgetting to do this!)
    • Going to change Travis up a little to further debug the constant job failures. Dropping cache: pip and setting up the build as either a matrix or stages. 🤞

What metro_wing?

pastel panther
#

Thanks @solar whale ! @gilded cradle It's an adapter I made a while back to allow you to use two feather wings with a metro/uno as well as a debug header for saleae's or whatever

#

I'm for reals going to do another rev and possibly do a larger run soon

gilded cradle
#

Nice. I also noticed a doubler or tripler turned sideways is about the same size as a metro, which is why I was wondering.

pastel panther
#

@gilded cradle Can I hit you with a DM?

gilded cradle
#

Yeah

old smelt
#

@idle owl - oh absolutely I have. That and other "hip" youngster vocabulary that is 2-5 years out of date.

idle owl
#

@old smelt Eeeeeexcellent. 😄

idle owl
#

@solar whale Are you around?

solar whale
#

yes

idle owl
#

I have a question. If someone wanted to do WiFi with CircuitPython right now, what would they need hardware-wise?

#

I realise it's separate pieces right now, but it's doable right?

solar whale
#

I'd recommend a feather Huzzah ESP32 and an M4 or nrf52840 board

idle owl
#

Ok excellent. So the Feather Huzzah could be attached to a Feather M4 and have a somewhat streamlined compact solution to CP and WiFi?

solar whale
#

no! can't attach them

idle owl
#

Ah ok

solar whale
#

not without cutting some pins anyway

idle owl
#

that's not an option 😄

#

Alright, but the two feathers separately will work, wired together specifically?

solar whale
#

yes - 6 wires

idle owl
#

Right on, brilliant. Thank you

solar whale
#

and it works well with any of the M4s or with the nrf52840 -- or even a particle xenon

#

the argon has an esp32 but you can't use ESP32SPI with ti -- only ESP32ATControl and ESP32SPI is much better

idle owl
#

Right

#

I recommended the Feather M4 or nRF52840 if they wanted BLE support, but explained where we're at with it.

solar whale
#

you can also use the ESPRESSIF ESP32 Development board ( a few $ cheaper than the Huzzah) I use both

idle owl
#

Hmm good to know

gilded cradle
#

I prefer the Huzzah32 because it's a narrower profile

idle owl
#

That's what I suggested.

gilded cradle
#

For the DevKit board, I always have to straddle it across 2 breadboards

solar whale
#

but I made a mistake -- it needs 8 wires!

idle owl
#

Ok!

#

Thank you @solar whale! And @gilded cradle

@slender iron I looked at ure, ujson, and uerrno. They are all proper subsets of the CPython functionality. So I think we can keep the alternate non-"u" names for them (re, json, errno) in 4.0. I'll add a long-term issue to move them to shared-bindings. I thought you wrote a comment somewhere about this, but I can't find it.

slender iron
#

kk, sounds good @tulip sleet

tulip sleet
#

do you think we should remove the "u"-names for 4.0? We'd have to do some library try-except work to handle that.

slender iron
#

ya, sooner the better I think

tulip sleet
#

ok, I'll search libraries for that. Maybe we have already done that to make them compatible for adafruit-blinka use

[adafruit/circuitpython] Issue opened: #1574 I2C scan/address bit order error

It sure looks a lot like there's a bit order reversal when handling i2c addresses.

I've got a custom board - call it a Trinket M0 (closest relative). I'm using an i2c port on SDA=PA22 and SCL=PA23. This port seems to be working normally, but only if I bit-reverse addresses. For instance, I've got a fuel gauge attached to the port with an address of 0x6C. However, if I i2c.scan():

>>> hex(i2c.scan()[0])
'0x36'

I can carry on using the device as expected, as long as I continue...

#

Hmm... having trouble booting 4.0b2 on a NRF52840 Feather Expresss... UF2 fails half way through copy saying the drive no longer exists?

#

With beta1, I can get the REPL to come up using Mu, but have no CIRCUITPY drive (says it needs to be formatted?)

manic glacierBOT
tulip sleet
#

@tough flax What is the bootloader version showing in INFO_UF2.TXT?

tough flax
#

This is what I get after a successful beta1 UF2 copy. For Beta2, I fail with the message above

📎 unknown.png
#

UF2 Bootloader 0.2.6 lib/nrfx (v1.1.0-1-g096e770) lib/tinyusb (legacy-525-ga1c59649) s140 6.1.1

Board-ID: NRF52-Bluefruit-v0
Bootloader: s140 6.1.1
Date: Dec 21 2018

tulip sleet
#

that's new enough. When you get the "You need to format" error, what's showing as a mounted drive, the ...BOOT drive or CIRCUITPY or nothing? Maybe CIRCUITPY needs to be wiped. But also, the first error is very weird, because it says the .uf2 is going missing from your C: drive, which shouldn't have anything to do with what's going on with the board

tough flax
#

Neither, it shows that a drive exists, but says it needs to be formatted

tulip sleet
#

maybe try another usb cable first

tough flax
#

No no...

#

I used it with the itsybitsy 10 minutes ago

#

it's fine

#

I mean I have others

#

I will switch, but don't bet on that 😉

tulip sleet
#

if you can get to the repl with beta1, you can do import storage;storage.erase_filesystem() to get a fresh CIRCUITPY.

tough flax
#

Comes up with the "needs formatting" after erase_filesystem

#

new cord

#

I shouldn't say yes, right?

manic glacierBOT
tulip sleet
#

this is very weird, so you can get to the repl when it says "needs formatting"? Is this a win7 or win10 machine?

tough flax
#

When I enter bootloader mode it looks like a normal UF2 mode (FTHR840BOOT)

#

win10

tulip sleet
#

i'll give you a very fresh uf2, hold on

tough flax
#

Adafruit CircuitPython 4.0.0-beta.1 on 2019-01-28; Adafruit Feather nRF52840 Express with nRF52840

#

beta2 seems to think its too big? Not sure

tulip sleet
#

but that's complaining that the file is going missing from c:\Users\billb ...

#

which is ccompletely weird

tough flax
#

Agreed... I'll record what's happening - the timing makes it seem like the board's resetting too soon

tulip sleet
tough flax
#

Ugh

#

hold on

tulip sleet
#

i have to cook, but will keep an eye on this

tough flax
#

video is too big

#

says its too big for the filesystem

#

#

wish i wasn't order-lazy and had a 52840 so i could try and replicate on win10. 😦 but those are some funky things happening.

tough flax
#

Yes, it takes the time to send the file (I see the transfer on the red led) and then I get this:

#

0 file(s) copied.

tulip sleet
#

i am getting a different weird error on my windows 10. Do you have a mac or linux box to try?

tough flax
#

And yet it did make the copy Adafruit CircuitPython 4.0.0-beta.2-91-g4e75aaecd-dirty on 2019-02-19; Adafruit Feather nRF52840 Express with nRF52840

#

Nope

#

I can delay this test

#

It can wait until the 840 is more stable

tulip sleet
#

@tough flax I think this is some weird windows interaction with the nrf52 bootloader. We've been loading uf2's from Linux and Mac all day without seeing this. Or maybe it's some brand new Windows Update quick.

solar whale
#

Or until windows 10 is stable 😉

tough flax
#

So...I tried another board

#

Still got this error

#

d:\Python>copy f52840-2019-02-19.uf2 f:
The system cannot find the file specified.
0 file(s) copied.

#

However, Circuitpy came up 😃

gilded cradle
#

Ok, I'm gonna try copying on a windows computer 10 to an nrf52840 board to see if that has an error on another system.

tough flax
#

The second board is coming up in safe mode

#

Ok, let me try beta1 on the second board

gilded cradle
#

Yeah, I had the same thing happen to me too

tough flax
#

beta1 comes up without being in safe mode

#

empty circuitpy drive

raven canopy
tough flax
#

still gave the error during copy

gilded cradle
#

I tried to copy beta2 and got file too large for destination system on Windows 10.

raven canopy
#

what does explorer "report" the drive size is?

tough flax
#

Yes - once I got that, I also saw it on beta1 until I unplugged/replugged the device

#

3MB

raven canopy
#

and available?

tough flax
#

hold on

raven canopy
#

:holding:

tough flax
gilded cradle
#

Same for me too

raven canopy
#

huh. i mean, its bogus numbers anyway, but...windows. 😄

tough flax
#

That's with beta1 after it actually started

gilded cradle
#

The beta2 file size is only 524kb, so it's pretty weird.

tough flax
#

I have this in the event log around the time those copies failed`

#

An error was detected on device \Device\Harddisk3\DR53 during a paging operation.

gilded cradle
raven canopy
#

i was about to ask if either of you had a USB debugger. MS Message Analyzer can do it, but its a little tedious.

gilded cradle
#

You mean software or hardware?

tough flax
#

I do not have a debugger (or a J-Link unfortunately)

raven canopy
#

either. wireshark is another software tool, but i can't remember if they have a windows version.

manic glacierBOT
gilded cradle
#

I'm pretty sure there is a windows version of wireshark

#

I also have a j-link

raven canopy
#

this feels more on the USB reporting side, but the j-link on the hw side may help pinpoint.

tough flax
#

There is wireshark for windows - not sure if there's a usb capture interface (I use it for ethernet/wifi)

#

To me, this seems like a bootloader issue

#

like it's trying to restart the board before it's done copying

raven canopy
tough flax
#

In the short-run, I can continue with the sip/puff project... and I have the dead board if you want me to help test with that. In the long run, this is obviously an issue 😃

[adafruit/circuitpython] New comment on pull request #1566: correct weak module links; samd module only in m4 ports; update frozen libs

What is your motivation for supporting them?

They add functionality that's missing from the C module.

For instance the time module adds these:

from _time import localtime, mktime, monotonic, sleep, struct_time, time

def asctime(t=None):
    ...

def ctime(secs=None):
    ...

def gmtime(secs=None):
    ...

def strftime(_format, t=None):
    ...

It doesn't seem very useful...

[adafruit/circuitpython] New comment on issue #1155: CircuitPython standard library

Repointing some discussion that was in PR #1566 to here. Trying to summarize:

We decided to make weakly-linked _ versions of a few modules that could be extended with Python versions derived from the CPython standard library. Right now, this is just os and time, though there could be more.

We have not enabled the "weak links" (module alias) mechanism in the M0 builds. There is not enough RAM or unused flash in the M0 builds to make using this practical, so it would be for the M4 a...

@pastel panther I almost alwasy merge because it's easier, less chance for mistakes. I don't care about the extra commits. If you're confident about where to rebase that can work, but I've wasted too much time fixing bad rebases, after making simple mistakes. I once went to a git talk about rebasing and how "it's easy", and the presenter messed up his (simple) demo.

@slender iron do you have a minute for a question? or maybe more than a minute, I never know.

slender iron
#

sure

idle owl
#

ok, so in this driver, there's gain and integration_time registers, which you can read and also set. setting them, there are variables with constants. but I realised while doing other things, the first four constants are the same for both, meaning there's nothing stopping someone from setting gain = ALS_200MS which is an integration_time setting, because the constants are (0x0), (0x1) etc. If I weren't using register, I'd have to be creating properties to handle the getting/setting, but since I'm using register, the property is created when the register is created. So my question is, how do I make it so you can only use the appropriate variables, and throw an error if you don't?

#

other drivers have it happening in the property that handles setting the register. but that's not how this works, so I'm not sure where to handle it.

slender iron
#

right, you'd like the property to make sure the value is valid

idle owl
#

yeah, but it's not a normal property because it's a register line.

slender iron
#

right

idle owl
#

ok

slender iron
#

I doubt there is much you can do

#

the property or register can't tell the difference between two constants of the same value

idle owl
#

right but in the property you could force it to read the variable name, and only accept those 4 variables, right?

#

or does it all come down to the constant in the end

slender iron
#

nope, at that point you don't have the variable name

#

it would cost memory to have the value know what register it was for

idle owl
#

ok

slender iron
#

you could add a check for values 0-4 even on a three bit register (0-7 total) but I'm not sure its worth it

idle owl
#

alright. thanks

raven canopy
#

couldn't you class them (class sensor.Gain)? Still, I'd consider it wasted memory

slender iron
#

even then its usually just an integer constant in the class

idle owl
#

I have dicts with the variable: integer value already because it's required to calculate something else, but that only helps with this particular driver. not the other one, for example, that has a TON of variable constants that match.

[adafruit/circuitpython] Pull request opened: #1581 Use critical section, not lock, in CharacteristicBuffer; use a root pointer for ble\_drv list

Two problems with BLE:

  • Used a lock instead of critical section in an interrupt routine, causing a deadlock.
  • Needed to make the ble_drv linked list start with a root pointer. Its allocated storage was getting gc'd and reused.

I reordered some #include's for clarity, but the order doesn't matter (I thought it did).

Partly fixes #1568. The other part is https://github.com/adafruit/Adafruit_CircuitPython_BluefruitConnect/pull/10.

@marble hornet it's been moved to /py/circuitpy_mpconfig.mk. displayio inclusion is based on CIRCUITPY_FULL_BUILD, which is default and "turned off" by defining CIRCUITPY_SMALL_BUILD = 1 in the board's mpconfig.mk.

It still prints in a really inconsistent order.

I guess that's a limitation of the setup.

I'm not seeing that on ios, so maybe Android is sending some packets more often than others. I can try that

naturally

#

ok so I don't know what to do for the example then if Android is going to bork it all up. I would say save them all to variables and then only print when it has all 4 packets, but then you wouldn't be getting up-to-date data because the accel packet might now be 3 seconds old by the time it gets another gyro packet or whatever.

tulip sleet
#

i don't think it's so bad, or maybe you should file an issue on the Android app

idle owl
#

I guess. Still want to ask Limor if it's satisfactory to her. She seems to have some idea what she wants for this guide.

#

still running though!!

#

for at least 8 minutes

prime flower
#

@solar whale did you end up figuring out the json pkt size issue with ESP32WiFi?

tulip sleet
#

well, my tablet doesn't have a magenetometer , the gyro is sending nothing, so I"m only getting accelerometer data. The location data is "waiting for location data", so not much of a comparison here

#

🤷

idle owl
#

lol

tulip sleet
#

the location data on the screen is changing furiously, but it's a lot slower printing on the nRF side (slower than on iOS). Not sure what's going on with that.

#

the tablet is also downloading updates...

idle owl
#

😄

#

Sounds like the true mobile device experience there.

gilded cradle
#

@prime flower, it’s not a packet size issue, but rather a json parsing issue. There’s an issue open on the ESP32SPI repo with more info.

prime flower
#

@gilded cradle checking it out, thanks

idle owl
#

@tulip sleet The important thing is, it's still running. I'd say the demo issue I'm having lies with the app, not anything we can do in CP or the lib. I can merge everything.

#

ooh thought it crashed there! but then it spammed a bunch really fast and went back to the normal speed.

#

hmm... it slowed

#

and stopped.

#

at 20 minutes.

#

BUT!

#

I could still ctrl+c to reload

#

so maybe my phone dropped connection that time. It didn't crash obviously.

tulip sleet
#

I"m not so sure that's not the app, yeah. I ran for about 15 mins w/no changes with iOS.

idle owl
#

Alright. I want to merge it. I think you fixed the issues. The way it just failed is not like it did before, it didn't crash the board, it simply stopped sending data.

#

Travis failed on the BLE Connect one

#

didn't look at why

tulip sleet

it's a lot better than it was. I can do a longer test

I'm assuming I'd have to keep my phone awake the whole time. I'm thinking it went to sleep.

@solar whale I saw a comment where you mentioned that ESP32SPI is much better than ESP32ATControl. Why is that?. I'm considering using an Argon for a project. I need WiFi and want to do it on CP.

manic glacierBOT
pastel panther
solar whale
#

@gusty topaz the ESP32SPI intrerface is much more reiaible and faster then the UART. I get a lot fewer errors. That said, the ESP32_ATcontrol works best for me on the Argon with the onboard ESP32. I do find it best to keep the baud rate at 460800 rather than the 921600 in some of the examples. If you are just doing basic "requests" I think it will work OK.

#

I would not recommend using an ESP8266 with ESP_ATcontrol since the support for SSL connections if very limited.

gusty topaz
#

Got it. Do you know if there is a mqtt client library/module out there compatible with CP?

solar whale
#

I have not tried it other than the micropython mqtt client that worked on the ESP8266. I'm not that familiar with it.

#

I do thatn now with micropython on an ESP8266 if I need it.

#

but I have moved most of those applications to Raspberry Pi's and use the CP libraries via Blinka. Gives a lot more flexibility for Wifi internet access but allows me to use the CP libraries for sensors.

gilded cradle
#

I suspect that as CircuitPython gets more WiFi stuff, MQTT will become more important. I’ve used it a bunch on the Arduino side. I’m not sure how complicated it would be to write, but it’s something to look into.

solar whale
gusty topaz
#

@solar whale that's a good option, but I'd rather use a single-purpose board for this project instead of a RPi. @gilded cradle yeah, hopefully that's the case.

solar whale
pastel panther

@tidal kiln or @solar whale or anyone else, if you have a pyportal or hallowing and can test the bitmap I posted above when you have a second, that would be great

tidal kiln

@pastel panther no pp, but do have hallo. anything special firmware-wise?

tulip sleet
#

@solar whale @gilded cradle we were discussing this last night internally. Point made that if HTTP REST is available, MQTT is less important. MQTT more important for reducing data use on cellular, etc.

pastel panther
#

nope, just a regular OnDiskBitmap should be fine

solar whale
#

@pastel panther sorry -- I am away from my hardware until later today -- looks like you have others

gusty topaz
#

@solar whale bummer, that's too bad. I guess I'll have to do it on the Huzzah. Weird thing is that it was giving me some errors and I couldn't get it to allow me to access the repl last time I played with it (it would freeze and the board would restart).

pastel panther
#

I tested beta2 and current master so those are a good targets to test but others would be fine too

solar whale
#

@tulip sleet good point -- that is why I have not found it necessary to look into MQTT myself REST gives me all I want.

tulip sleet
#

@prime flower was part of this discussion - may have further things to say

gusty topaz
#

What do you mean by REST?. Are you referring to the regulat Get/Post requests?

tulip sleet
#

yes

solar whale
#

@gusty topaz I've never had issues like that -- if you can provide examples, I'll try them and see if I can reproduce the issues.

#

@gusty topaz yes (get/post...)

gusty topaz

ok, I'm away from the huzzah right now, but will try later or perhaps in a couple of days.

@gusty topaz were you referring to CP on the Huzzah esp8266? I may have misunderstood. It has not worked at all since 4.0- alpha2 I think

#

I don't use it at all anymore.

gusty topaz
#

@solar whale no, I was referring to MP on the Huzzah ESP8266.

#

I did a project some time ago with MP and MQTT and it worked beautifully.. until it didn't.

prime flower
#

@gusty topaz I tried out uMQTT back in September, pre-ESP32SPIWifi work. It wasn't great at the time. The Adafruit IO CircuitPython library (I'm writing it rn) has a RESTClient class, leaving the possibility of adding a MQTTClient open for the future for when we have a MQTT client.

solar whale
#

oh -- OK -- I do have that available and can try it.

#

@prime flower will you make it work with both ESP32SPI and ESP_ATcontrol?

prime flower
#

@solar whale Maybe, I've been working with ESP32SPI's WiFiManager? What's the difference btween the two as far as hardware targets?

tidal kiln
#

@pastel panther can you send code snippet to test

solar whale
#

the ESP_ATcontrol uses a UART interface and works with the ESP32 or ESP8266 (and ESP8285) - @gilded cradle is , I think, planning ot provide a WifiManger for ESP_ATcontrol as well.

manic glacierBOT
gusty topaz
#

@prime flower Do you think uMQTT would work with CP4 on an Argon? (WiFi through ESP32_AT control)

prime flower

@median aurora I'm happy to include both the SPI and UART interfaces within CircuitPython_AIO as they come in

#

@gusty topaz not sure, havent tried the argon with ESP32_ATControl, been using a PyPortal for testing

pastel panther
#

offline for a bit, bbl

gilded cradle

Yeah, I was waiting for the bugs to get worked out, but was going to basically port the one from ESP32SPI one. @prime flower, if you would like to write it, that would be great. Just let me know if you have any questions.

prime flower
#

🤷 the more hardware support the merrier 😃

gilded cradle
#

Otherwise, I’ll probably work on it this weekend. I’m having to squeeze in dev time where I can this week.

prime flower
#

I could probably start on it tomorrow, depending how far I get with the IO lib. I'll let you know.

solar whale
#

@prime flower @gilded cradle hopefully the only diffence is what is passed to the wifimanager -- an esp32spi or a esp_atcontrol instance.

prime flower
#

if it mimics the .post/.get methods of WiFiManager, absolutely

solar whale
#

If not, we should make it so 😉

prime flower
#

restclient takes in a wifi_manager object

solar whale
prime flower
#

im all for making sure the APIs have similar calls, less code in the lib to handle diffs

solar whale
#

there may be some things in ESP_ATcontrol that need to be tweaked since ESP32SPI has evolved. I'm happy to help make them play together as well.

#

@gilded cradle don't feel bad if life happens! All this can wait...

[adafruit/circuitpython] New comment on issue #1577: PYPORTAL: wiped itself

Since you have a JLink, it'd be awesome if you could have a debug build running through the JLink as you work with it. Set a breakpoint on reset_into_safe_mode. It will likely be triggered when the USB dies for you. If it doesn't, you can still control-c it to get a backtrace. You may also want to power the pyportal separately through a stemma connector so that you can unplug usb when it misbehaves. I use gnd and 5v from a grand central or metro to power the pyportal.

You need to install it from the installer found on the GCC website.

@idle owl all i'm finding is targx.bn2 files online, do you have a link? please

Someone else made a brew thing for it. https://github.com/PX4/homebrew-px4 You would do brew tap PX4/px4 apparently. But I don't have any information on that at all.

tried it compiling cp sin;t working

tulip sleet
#

don't bother to put it in bin; just make your own ~/bin and add that to yoru PATH. That's a lot safer. Just untargz it somewhere in bin and then do that.

#

you need the q3 7.3.1 version, not the gcc8 version

marble hornet
#

can you go into a little more detail ?

gilded cradle
#

I think the correct directory is /usr/local/share, but get the correct version as dan says too.

tulip sleet
#

download the tar.bz2, unpack it in some dir in your homedir. find the bin dir in the packed dir, and add that dir to PATH in your .bash_profiel (or whtaever it is on MacOS)

#

there's no reason to do anything as root, or put it in /usr/whatever. you can make your own private bin directory for random stuff

#

it's safer if you don't

#

unless you're installing it for other people on a shared machine

gilded cradle
#

True. I was going by the fact that homebrew stuck it in /usr/local/Caskroom, but it's fine either way.

tulip sleet
#

@marble hornet is that still clear as mud? Have you modified your PATH before?

marble hornet
#

no

#

i've seen export but that;s it

#

sorry: yes to mud, no to path stuff

tulip sleet
marble hornet
#

awesome! before i put it into my path i exported it to the envi where i was trying to build cp and this is what i got:

#

tulip sleet
#

we haven't brought the tinyusb code up to snuff for compiled on gcc8 yet, so use the gcc 7.3.1 release instead

marble hornet
#

oh 731 not 371

#

i'll try to find it

Scroll down the page of the link I sent, @marble hornet

Guys, quick question: The only way to interact with Bluefruit boards through BLE is through Adafruit iOS App?. Is there a way to pair the board with a phone and have it change the phone volume or snap a picture, for example? (much like selfie sticks)

idle owl
#

Or click that link too

tulip sleet
#

@marble hornet messing around in .bash_profile and .bash_aliases is a good skill to have. You can add all kinds of aliases to save typing, like I have lots of aliases like:

alias f840-make='make -j4 BOARD=feather_nrf52840_express SD=s140'
marble hornet
tulip sleet
#

@gusty topaz we don't have pairing yet. The BLE app uses the "standard" Nordic UART service, which a few apps implement. BLE HID is high on the list, but not started yet

#

2018-q2, really. they made a mistake and called it q3 in some palces

#

the link I posted above

#

2018 q4 is the gcc8 release, which doesn't work.

#

for us

#

yet

marble hornet
#

kk 😃

#

🔨 ing

tulip sleet

afterwards you can check the version:

it says q3 there and q2 in the download 🤦

marble hornet
#

ooh those alias seem really cool (havn;t tried still reading)

#

or say alias 'git submodule sync; git submodule upade --init --recursive'?

manic glacierBOT
marble hornet
#

where is ~/.profile?

tulip sleet
#

do ls -a and see what "dot" files you have. More likely it's .bash_profile? Have to fire up a MacBook to look

manic glacierBOT
marble hornet
#

where should i run that ?

tidal kiln
#

~ = your home directory

marble hornet
#

so /?

tulip sleet
#

I have Mac with a vanilla install. There is not any .bash_profile, so you can create one.

#

$ cd ~

tidal kiln
#

/ would be the root folder

#

~/ is your home directory

tulip sleet
#

your homedir is /Users/yourusername

manic glacierBOT
tidal kiln
#

echo ~

#

it's just a built in short cut

manic glacierBOT
marble hornet
#

should i restart ?

tulip sleet
#

no, just open a new terminal window, and it will read .bash_profile

#

if you put echo hi there at the top of the profile you'll see it print that proving that it has read .bash_profile

gilded cradle
#

Even more of a shortcut is to just type cd to go to your home directory.

marble hornet
#

r u on mac?

#

(i don;t remember )

#

sorry

tulip sleet
#

well, i have a couple i use for testing, but ubuntu most of the time.

#

cd with no args works on all *ix-style shells

gilded cradle
#

You can also type source .bash_profile if you don’t want to restart the terminal.

tidal kiln
#

my recent fav:

alias dmesg='dmesg -T'
marble hornet
#

okay, so now that this is working i think i found something odd with the pyp ;
also: can i put aliases in the .bash_profile?

gilded cradle
#

Yeah, that’s where I put mine

tidal kiln
#

yep

prime flower
#

@solar whale I think I'm going to PR AIO_CircuitPython in a bit and build hardware for a soak test over the weekend, tomorrow

marble hornet
#

can you have an alias with an input?

prime flower
#

the cheerlights issue you encountered, I havent' hit that yet, but i havent been running this library > an hour

tulip sleet
#

@marble hornet no, but you can write a shell script that processes arguments

#

or write a shell function

tidal kiln
#

and then alias that 😃

marble hornet
#

ahaha

solar whale
#

@prime flower sounds good -- I'll give AIO some exercise over the weekend as well. I try to run cheerlights cointinuouly asa check -- it has hung before and I just rebooted it without looking at the REPL. I'll pay closer attention. It often runs >24 hours without a problem.

marble hornet
#

yay!

solar whale
#

@prime flower will you want the PR approved and merged right away or do you want to wait until after your soak test

@solar whale dunno, it'll be an initial PR/code review. I'm not going to do a full release until after the weekend, though

pastel panther
#

(apologies for the text dump)

tulip sleet
tidal kiln
#

@marble hornet also, you can type alias to get a current list

marble hornet
#

thank you!

solar whale
#

ok -- on thing that would be good is to change the name of settings.py -- it caused some problems with taht name -- either use aio_settings.py pr esp32spi_settings.py

#

at least needs to be done before release

prime flower
#

@solar whale Not sure if we decided on a final settings.py rename, but I could do that for now

solar whale
#

also all the examples have to change to import settings from the new name

pastel panther
#

steals from Dan's aliases

solar whale
#

do we want one setting.spy for all -- them maybe wifi_settings.py

manic glacierBOT
prime flower
#

was going to do wifi_settings.py and include io API keys in there

solar whale
#

sounds good to me.

#

the complication will come if multiple libraries have exmples with wifi_settings.py unless we have a common "default" since it will get merged into the bundle for each library -- maybe @idle owl has a suggestion

idle owl
#

Leave it in the root directory and it won't go into the examples bundle, if that's what you're referring to.

solar whale
#

hmm - but it does not belong in /lib

marble hornet
#

do any of you have a pyp?

manic glacierBOT
marble hornet
#

can you try some firmware on ur units?

idle owl
#

@solar whale It shouldn't end up in /lib either.

#

@marble hornet Very few people have them.

solar whale
#

@idle owl I guess I don't understand

marble hornet
#

okay

#

here is the thing: i have to versions of teh firmware compiled one with the dispio init and one without. the one without seems to not loose files

idle owl
#

I'm saying if you have it in the same directory as the library file or package, so along side adafruit_esp32spi.py and .travis.yml and setup.py, it shouldn't end up in /lib either. Where and when do you need it? It won't be in the bundle at all at that point, you'd have to get it from the repo. Otherwise, it will end up in the bundle and there will be duplicates.

#

Where is it now? Are there libs in the bundle with them already?

#

You could choose one library to host the wifi_settings.py and then get it from there in the bundle each time also.

prime flower
#

@solar whale On the PyPortal, it sits at the root, so I don't think it will/should be included with the library, it's not part of ESP32SPI. Those examples reference settings as esp32spi_settings

solar whale
#

OK -- it was in the examples folder of ESP32SPI and ESP_ATcontrol -- right we changed the name at @idle owl request for esp32spi -- The only place it is ever imported is in a file from the examples -- I guess we just need to make it clear in the guides how to create it and what goes in it.

prime flower
#

good point - I'll clarify in the guide

solar whale
#

esp32spi_settings.py is in the examples folder for esp32spi.

#

not sure we want or need aio_settings.py and esp32spi_settings.py and espat_settings.py.. all could use wifi_settings.py

manic glacierBOT
solar whale
#

They could all import wifi_settings.py as settings

manic glacierBOT
solar whale
#

or use any file name the user wants since it is in the users code

prime flower
#

@solar whale yeah, I'll do wifi_settings for now, since it'll support both

#

eventually

solar whale
#

that sounds good -- we'll make it work

#

and @idle owl I did NOT swear at you 😉 the bot does not like triple-x and I used that in an example ...

prime flower
#

@solar whale example_file_name.py next time 😄

solar whale
#

@prime flower if you are making changes to the examples -- you can remove all the gpio0 settings -- they are defined, but not used and not needed

prime flower
#

ok

solar whale
#

one less pin tied up

#

one last comment for now regarding the settings.py - the important thing is that some file contains a dictionary named settings and your code has to then 'from your_file import settings .

#

Sorry I think I am way over thinking this. Since its is all example or user code you can nene the dictionary anyway you want... I’ll stop now.

manic glacierBOT
marble hornet
#

could you just have the user pass the dict?

#

for wifi

manic glacierBOT
solar whale
#

@marble hornet that is what happens. I was the one making it complicated.

marble hornet
#

oh, so it will be moved to __init__ ?

[adafruit/circuitpython] New comment on issue #1577: PYPORTAL: wiped itself

I duplicated the pyportal board profile and changed the board.c to match the metro m4, thus board.DISPLAY is a Nonetype, and I have not been having the file/folder (and occasional) corruption problem while saving or reloading in addition to far fewer safe mode alerts. The board i am running it on is in spi mode, if relevant.

ladyada, thank you for the feedback you have been giving I have been finding it very useful and I hope I can someday use it in a job. :-)
