@solar whale Thank you so much. I really appreciate it.

@solar whale Do me a favor and comment on the PRs that you're starting testing as you test them so I'm not grabbing the same ones. Hasn't happened yet but could.

@idle owl oops _ I released the lsm9ds1 without merging -- should I jsut re-release and bump the version ?

idle owl
#

yeah

#

That works

solar whale
#

can we delete 2.0.3?

idle owl
#

It can mess with things if we do. I've done it many many times when dealing with PyPI, but you need to go delete the tag as well.

solar whale
#

I changed the title to "ignore this release" let me know if you want me to leave it as is or delete it

idle owl
#

Might as well leave it. Like I said, things can get wonky if it's deleted improperly.

No worries, versions are free πŸ™‚

[adafruit/circuitpython] New review comment on pull request #2085: Rework display refresh, add M4SK and add ePaper support

I think it would be better to remove it and just leave it as CIRCUITPY. Mu depends on that name a lot of places, and all our documentation assumes it as well. I'd see this as a constant support issue. Using CircuitPython to init the M4SK is a hack, and can be improved in the future. In either case, there's going to be some confusion about the filesystem name; I think it would be easier to explain the M4SK drive as CIRCUITPY when not using CPy than as MONSTERM4SK when using CPy.

[adafruit/circuitpython] Issue opened: #2086 PWMOut failed when changing frequency in an infinite loop

I try to understand why it failed to generate PWM signals after 30+ seconds or so on my ATSAMD21G18. Other functions (such as print) seem to work just fine but just the PWM function stop generate PWM signals.

I did test it when changing duty_cycle in an infinite loop, and it works just fine. Not sure why it causes a problem with switching frequency. Any thought?

The code is pretty simple as:
import time
import board
import pulseio

PIN_Test = pulseio.PWMOut(board.A4, frequency...

Thank you for your report.

I believe I have reproduced the problem. I happen to be testing with Adafruit CircuitPython 3.0.3 on 2018-10-10; Adafruit Feather M0 Express with samd21g18 and I used a modified version of your test program:

PIN_Test = pulseio.PWMOut(board.D5, frequency=5000, duty_cycle=2 ** 15,  variable_frequency=True)

I get the same error from twine when building version 1.7.1, so .. is there any possibility it's a new change at pypi?

i guess the PR doesn't trigger the deploy, only the merge

so that explains why the PR could be green, and merge red

yes that's true

What's the best way to jump into CircuitPython for porting it to the PyGamer?

[adafruit/circuitpython] Pull request review submitted: #2085 Rework display refresh, add M4SK and add ePaper support

Still also thinking about the refresh() calls, especially for ePaper. For a really long refresh cycle like ePaper, maybe the old refresh_soon() makes sense. But could call it schedule_refresh(), or refresh_needed(), or similar. There could also be a call seconds_until_refresh() that would return how much more time there is, and maybe even a 'refresh_done` property after that.

I'm thinking about some kind of use case where you might, say, light up an LED to indicate a refresh is o...

I may have found a bug in the circuitpython lis3dh driver

or rather my rust compiler found it

DATARATE_LOWPOWER_5KHZ   = const(0b1001)

oh nevermind

looking at the datasheet it switches datarate based on whether or not it's in low power mode

that's annoying because I can't turn it into an enum

Hi, I found out that the Arduino Zero supports Circuit Python and I'm wondering if It'll work with the Arduino M0 Pro?

exotic pumice

it will if someone adds a board definition

Is it something that I can do?

By the way, I'm not that familiar with Circuit Python. I'm just getting started

@tulip sleet i think i figured out how to re-import modules

#

if foo prints ''asdfljshf'' in the first line ```>>> import foo
asdfljshf

del sys.modules['foo']
import foo
asdfljshf

#

my question is will old modules still stick around if there are no references to it?

#

okay, looks like it will be deleted! i ran a test where foo makes a 1,500 obj long list. then ran the following in the repl .

# 
while 1:
    x = gc.mem_free()
    import foo
    v = gc.mem_free()
    del sys.modules['foo']
    g = gc.mem_free()
    gc.collect()
    l = gc.mem_free()
    print(x-l, x,v,g,l)
    gc.collect()
    time.sleep(.25)```

@marble hornet Congrats! Your persistence seems to have paid off.

marble hornet
#

thank you, the though and planning that the creators of python put into the design continues to impress

#

and thank you for letting me pic your ear all this time

onyx hinge
# 
    import sys
    name = module.__name__
    if name in sys.modules:
        del sys.modules[name]
    return __import__(name)
``` maybe you can package up a importlib.reload() function then.
#

the above "works" (I didn't check the gc memory usage change though) in the unix circuitpython test program

marble hornet
#

sounds like a great idea! altough if there are still references to the old memory might fill up quite quickly

#

maybe a deport function so people can deport without re-importing

onyx hinge
#

ah right, I forgot your use case for a minute and thought about mine

#

which is that I want to interactively reload modules that I modified, but if that is by writing to the FAT filesystem then there are other troublesome considerations I guess.

#

and yeah, this kind of "reload" can't change existing objects to refer to the newly imported class, for instance

marble hornet
#

i was thinking, for my case to make to limit references by having a controlling object

#

or module

# 
import sys
apps = [] # or a class where appending adds a new attr with the name of the appended obj and del removes said attr 
# thus: obj.module_name would make for sugary code

def import_app(path, cntr)
    module = __import__(path, cntr)
    if module.__name__ in sys.modules:
        del sys.modules[module.__name__]
    cntr.append(module)
    del module, path

import_app('foo', apps)
#

and you could theoretically have multiple instances of the same module loaded !

#

woah!

onyx hinge
#

In the mists of time, I recall using (maybe even writing?) something that could go out and find instances of classes in a reloaded module and update those too, so that the running instances didn't refer to the old classes anymore. I think it had to use trickery to find the instances, which is almost certainly not going to translate directly to circuitpython

[adafruit/circuitpython] New comment on pull request #2080: Add audiocore\.MixerVoice

Fixed most of the above, and moved Mixer to a new audiomixer module. After this Travis build, I'll run through the failures and disable accordingly.

Please let us know if you'd like to hand it off.

I'm happy to push it through to the finish. But, if it's time-sensitive, no problem with passing the baton. I feel I can finish the ASM/CMSIS math functions; just takes time for me to bolster my understanding.

marble hornet
#

might they all append the instances to a list of class instances

#

rather what i;m asking is is what trickery is that?

@waxen loom The Bluefruit app works as a central, so it cannot connect to another central. You can use ble_demo_periph.py and ble_demo_central in a pair on two boards.

you will see it echoing in the bluefruit app, but not on the serial connection

#

@waxen loom what control pad is it?

waxen loom
#

@merry turret in the Bluefruit app in central mode under Controller - Control Pad. I just simply echoed out into the terminal the result of the keypresses however I reverse engineered the codes so you can literally take my example code and add servo motor logic or anything in there.

tulip sleet
#

You use the ButtonPacket class

waxen loom
#

ooh nice

tulip sleet
#

I should add an example of ButtonPacket to the library

waxen loom
#

I wanted to create a way to use the arrow and number buttons.

tulip sleet
#

code may be outdated now

#

look at teh code in both those Learn Guides. No reverse engineering needed.

waxen loom
#

ok

tulip sleet
#

@waxen loom basic examples of reading button pushes ^^

solar whale
#

I use the ButtonPacket for driving my ble_rover -- works great

waxen loom
#

Nice!

tulip sleet
#

the CircusPython code is old -- I should update it

waxen loom
#

Did not know it excited so that is why I created my own hack but awesome to see and will read it.

solar whale
#

probably only change needed is uart_server

#

πŸ‘‹

tulip sleet
#

@waxen loom your reverse engineering shows dedication! We need better cross references in the Learn Guides

waxen loom
#

Thanks @tulip sleet ! I LOVE the community here and am excited to see more people developing and making and sharing.

#

@merry turret currently the MAC iPhone App crashes the Bluefruit when reading the Accelerometer, or other non-Control pad related functionality as I have been trying to RE that as well.

solar whale
#

Hmm, I have not had issues with it.

#

Ah it will crash if you send packet it is not expecting.

waxen loom
#

@merry turret FYI made the simple adjustments for your example if you want to update your code example

#

from adafruit_ble.uart_server import UARTServer
from adafruit_bluefruit_connect.packet import Packet
from adafruit_bluefruit_connect.button_packet import ButtonPacket

uart = UARTServer()

while True:
uart.start_advertising()

# Wait for a connection
while not uart.connected:
    pass

while uart.connected:
    if uart.in_waiting:
        packet = Packet.from_stream(uart)
        if isinstance(packet, ButtonPacket):
            if packet.pressed:
                if packet.button == ButtonPacket.BUTTON_1:
                    # The 1 button was pressed.
                    print("1 button pressed!")
                elif packet.button == ButtonPacket.UP:
                    # The UP button was pressed.
                    print("UP button pressed!")


# When disconnected, arrive here. Go back to the top

@solar whale current firmware: Adafruit CircuitPython 1d973a0 on 2019-08-22; Adafruit Circuit Playground Bluefruit with nRF52840 - When I attemt the Quaternion, Acceleromtor, Gyro, Magnetometer, Location it shows initial data and then says disconnected and I then have to reset the device. Likely a small issue will try again in next alpha release.

solar whale
#

@waxen loom I’ll look at it later, am away from my desk for awhile. IIRC it is just looking for specific packet types and needs to be generalized a bit .

waxen loom
#

@solar whale no worries being in Alpha very normal but will keep tracking.

good evening!

onyx hinge
#

@slender iron have any links about your gameboy stuff? it seems like what you were alluding to is a lot lower level than what I was thinking about with my C64 project

slender iron
#

yup, hold on

#

basically queue up cpu instructions from the cart

onyx hinge
#

@slender iron wow, great presentation. I know c64 expansion/cartridge port has a way for the inserted device to do DMA and that there have already been 'external CPU" devices, so something similar might be possible. It goes beyond my level of understanding though.

exotic pumice
#

yeah there was an official cartridge with a z80 inside!

#

for cp/m

#

and accelerator carts and all kinds of stuff

#

it's pretty wild what you can do on the c64 expansion bus

onyx hinge
#

whee that's the first pcb I've ordered in a looonngg time.

#

so much for working on bugs tonight

onyx hinge
#

and .. canceled (wow you can cancel? that's great). I am seeing conflicting information about the C64 user port details and need to find out the truth

exotic pumice
#

what do you need to know?

#

I have my Programmer's Reference Guide at the ready

exotic pumice
#

it seems to me that pin C and pin M are RX and TX

#

in fact it would seem rx is C, B and 7 and TX is M and 5

#

but remember rx goes to tx and tx goes to rx

your board looks fine to me

#

personally I would connect reset to a gpio but that's just me

exotic pumice
#

would be fun to combine with a huzzah board and make a modem

manic glacierBOT
onyx hinge
#

@exotic pumice Yeah others have def. done "wifi modems" for c64. Where I was stuck was at the ordering page for the connector, which said the C64 was .100 pitch, 22 pin. The other info I had was all saying it was .156in, 24 pin. This was the seller that my friend just happened to dig up while we were talking about it at work: http://store.go4retro.com/pcb-edge-connector/

RETRO Innovations
PCB Edge Connector
#

.. but with doubts about the connector I canceled the PCB order

onyx hinge
#

I'm not sure the value of reset from feather to C64 as there's no way to force load software like a terminal program from the user port into RAM.

@onyx hinge I appreciate that much! Thank you.

@waxen loom you're welcome. I have them bookmarked to read for myself, because I haven't done BLE yet and very much want to learn it soon

exotic pumice
onyx hinge
#

@exotic pumice that is my conclusion as well, I think this particular vendor has mislabeled something. So I ordered from someone else, and will resubmit the pcb order since I think it's right. Say, do you know of an explanation of how "UP9600" works, with respect to C64 user port serial adapters? I have found wiring diagrams for "normal" and "UP9600" but no explanation of what is behind the strange-seeming design.

exotic pumice
#

The page you linked says the expansion port is 44 0.1" and the user port is 24 0.156" which is correct. The expansion port is the cartrige slot. I've never heard of UP9600.

onyx hinge
#

@exotic pumice OK I must have just been confused last night.

Does anyone have the AMG8833 thermal camera breakout or FeatherWing and feel like testing some code? It appears I do not have one at the moment. I'll pull the code for testing and send it to you so you don't have to sort out how to test PR code if that would make it easier for you.

#

I apparently gave them away at PyCon, which makes sense, they're fairly fun to work with. And I don't know where my previous ones are. Due to the more fragile nature of them, they're not with the alphabetised breakouts.

tidal kiln
#

@idle owl i do. i'll try and get to that at some point.

idle owl
#

@tidal kiln Ok, thank you. Much appreciated.

tidal kiln
#

is this for the I2C PR, or something else?

idle owl
#

I2C

#

I'm going through to finish them up, and of course of the last 6, I don't have one of them. 🀦

#

Is it me or is there no updated guide for the current DS1307? I'm noticing it has a 5V pin, but not a 3V pin. The only guide is for what appears to be a previous iteration of the board, and it's wired to Arduino and therefore to 5V.

#

Do I plug the 5V pin into USB on the Feather M4?

solar whale
#

@waxen loom FYI -- here is a simple script that accepts all of the conttoler inputs from the bluefruitconnect app. I ran it on a CPB but it should wokk on any ble device.

πŸ“Ž ble_sense.py
tidal kiln
#

@idle owl that guide does seem a bit dusty. i think the DS1307 requires 5V though. from product page:

it requires 5V power to work (although we've used it with 5V power and 3.3V logic successfully)
idle owl
#

USB provides 5V right? Do I remember that right?

#

Or do I need a Metro for this

tidal kiln
#

yep

idle owl
#

Ok

tidal kiln
#

USB is 5V

idle owl
#

Been a while since I used it, so I wanted to verify, thank you

#

@solar whale Thank u. Can the Bluefruit control a servo or do I need a cricket. Would like to build a small bit like yours.

glad sparrow
#

@slender iron WRT to who is using the audioio.mixer class in 4.x, I’ am. In fact, I’m really looking forward to having the ability to dynamically change volume per β€œvoice” on the fly. The reason this is important is because it will allow changes in loudness based on 6-dof readings. So, imagine swinging an axe or saber, and the volume intensifies as rotational velocity and linear acceleration increase, and then soften as velocity and acceleration decrease. Is there some CP code already in development?

slender iron

πŸ˜„ thanks for speaking up @glad sparrow

#

exotic pumice
#

you want the cpx crickit not the feather crickit

idle owl
#

@tidal kiln Feather not seeing the DS1307 breakout.

#

Wiring checked, first instinct is to blame the power situation. Should I give up on the Feather and try a Metro? I feel like it should work on the Feather though. And that I'm missing something.

tidal kiln
#

how about an i2c scan? anything?

idle owl
#

I'll check it, but the error is that there's nothing at address 68

#

Scan finds nothing

tidal kiln
#

got a 5V board? like an uno?

idle owl
#

I do not, or at least I don't know where it is if the one I have is that.

#

Try it on a Metro M4 at least so it has a 5V pin?

#

🀷

tidal kiln
#

sure. just as another test. but that should essentially be the same thing.

idle owl
#

Datasheet apparently says it will work with 3.3v logic. (thank you @pastel panther)

#

Ok that's weird..... Metro wouldn't show up as long as the DS was plugged into it..... updating Metro and then trying again.

#

Playing nicer now. But it's still not seeing it. Does it have to have a battery in it to work? I thought the batteries were for holding time, not powering them.

onyx hinge
#

ooh I got my beta invite for github actions

pastel panther
#

@idle owl datasheet says vbat has to be 2-3.5v

idle owl
#

Hokay, so....... If I reset the Metro with the DS plugged in, it won't show up, NeoPixel doesn't light up, and even the tiny status LEDs don't work right. If I unplug it, it starts up fine.

pastel panther
#

rather it's "recommended"

idle owl
#

So... maybe I try a different breakout first.

pastel panther
#

ya

idle owl
#

Same thing.

#

Putting a battery in it.

#

Still does the same thing on reboot, but with the battery in it, it works.

#

oi.

#

ok

#

Pro tip: DS1307 doesn't work without a coin cell in it.

tidal kiln
#

was wondering about that

pastel panther
#

The datasheet says if you're not using a battery to ground vbat

idle owl
#

Thank you @tidal kiln and @pastel panther.

@onyx hinge me too! yay!

@tidal kiln I'll go ahead and test the update to the DS3231 you requested changes on.

tidal kiln

did you make changes? it probably won't work otherwise.

idle owl
#

Scott did.

tidal kiln
#

bon!

idle owl
#

I have one sitting here from another project, so I'll test the update and get it out of the way.

tidal kiln
#

excellent

#

there was another hiccup....with register...

onyx hinge
#

@slender iron I think you'll have it sorted before I have a chance to chip in, I have so many other tasks suggested to me to work on right now

idle owl
#

@tidal kiln ?

slender iron
#

np, πŸ™‚

#

we can always refine it later

tidal kiln
idle owl
#

Oh right.

onyx hinge
#

@tidal kiln I was just trying to find that

idle owl
#

Didn't @onyx hinge figure it out?

onyx hinge
#

so, I think the markup has ALWAYS been wrong according to pypi

tidal kiln
#

yep

onyx hinge
#

and we (someone) can add a "twine" command to travis to check it

idle owl
#

oi... ok

onyx hinge
#

still never found any notice from pypi explaining whether there was a deliberate change from "OK just show it as plain text" to "reject updates"!

tidal kiln
#

^^ yah. weird. that's what seems to have happened. but why?

onyx hinge
#

who knows how many CP repos that is waiting to bite, too

idle owl
#

Another library overhaul, just what I always wanted.

tidal kiln
#

thanks @onyx hinge for digging into that BTW

onyx hinge
#

glad to @tidal kiln

idle owl
#

@slender iron LIDARLite works. Presumably the simple_test is enough to utilise the function you wanted me to test?

slender iron
#

I assume so too. I haven't used the lib before

idle owl
#

Same until now.

#

@tidal kiln So to verify, you'll take care of AMG8833 when you get a chance? (Making sure before I move on)

tidal kiln
#

yep. and si4713.

idle owl
#

Is that still outstanding?

#

I must have missed that one.

#

I went based on emails so it could have missed my inbox.

#

I did miss that one. I should have it, would you like me to do it if I do?

tidal kiln
#

sure. if you want. you got something to receive the RDS info?

idle owl
#

uh

#

Maybe not

#

Oi, ok

#

looking at example

#

You're welcome to test that one πŸ˜„

tidal kiln
#

okiedoke

idle owl
#

Thanks much.

#

Let me know when you're done and I'll deal with closing the issue on the CP repo.

#

Actually, looks like I missed a few. Going through the issue now.

#

:sigh: @onyx hinge HTTPError: 400 Client Error: The description failed to render for 'text/x-rst'. See https://pypi.org/help/#description-content-type for more information. for url: https://upload.pypi.org/legacy/ On a new repo.

#

Running Adabot to get all the open PRs and I'll go through it that way because only one referenced on the CP issue doesn't say merged, and that means that it wasn't referenced on all of them because there are at least 2 outstanding now.

#

Or I don't know how to click on "show hidden items". πŸ™„

#

That's better. Ok. I think we're caught up to the last two now.

manic glacierBOT
idle owl
#

@onyx hinge Did you deal with PDM in CircuitPython?

#

PDM mic

#

Looks like you did. Did you use CPX for everything or did you use the PDM mic breakout?

#

@onyx hinge Sorry, I should read the PR. You explained. I have a couple of questions/requests when you're around.

onyx hinge
#

@idle owl go ahead, I'm free right now

idle owl
#

@onyx hinge How did you wire up the breakout? And do you still have the playground sound meter code you adapted?

onyx hinge
#

@idle owl hum, I would have to go look at it. I am pretty sure there were 4 connections to the mic breakout: power, gnd, clock, and data

#

hold on,

idle owl
#

Yah that's what I have

#

D6 and D9.

#

No example code so I don't have an example to use

#

for CP anyway

onyx hinge
#

and SEL I left unconnected

idle owl
#

ok same

onyx hinge
#

I'm at the office and I can't seem to access the computer which might have the .py file

idle owl
#

Ok

onyx hinge
#

for nrf you should be able to select any pins as far as I know

idle owl
#

I'm using Feather M4.. wondering if your example might not work anyhow

onyx hinge
#

I'm pretty sure limor pointed me at the demo program

idle owl
#

Ok

#

I'll try to adapt it myself then

onyx hinge
idle owl
#

Yah that's it

#

Ok, I was thinking you did a bunch of adaptation to it

onyx hinge
#

I don't think it too much, it went real fast

idle owl
#

Ok

onyx hinge
#

and probably I had to specify my neopixel details , I have one of those sticks with 8 LEDs on it

idle owl
#

I should have one of those too but I think I'm supposed to do plotting, not NeoPixels

#

so I need to strip it down some.

onyx hinge
#

oh in Mu?

idle owl
#

yah

onyx hinge
# 
    magnitude = normalized_rms(samples)
    # You might want to print this to see the values.
    # print(magnitude)
``` I bet delete the rest of the loop and change the print statement to meet mu's requirements
idle owl
#

Right on, thank you. I would have started further into the loop I think

onyx hinge
#

you might try before/after the "log scale" step

idle owl
#

invalid clock pin

#

hmm

onyx hinge
#

hmmm there might be restrictions on SAMD

#

wow the source code is complicated

idle owl
#

Found two pins that work

#

Weirdly the list in the guide I linked isn't right

#

But board.TX and board.D12 worked for clock and data respectively

onyx hinge
#

wait that's i2s, not pdm

idle owl
#

yeah which confused me, because the arduino page is referring to an I2S peripheral

onyx hinge
idle owl
#

I feel like I'm getting garbage data though

#

If I touch it, it gives me data, otherwise it's 0.0

#

snapping at it or whatever does nothing

onyx hinge
#

if you touch it? that seems very weird to me as well

idle owl
#

like if I tap it

#

even that doesn't work this time

onyx hinge
#

if you are using the sound meter, try to make sure it's close to quiet in the room when you start the code

idle owl
#

tapping it should be really loud.

#

it's close.

onyx hinge
#

it tries to guess the ambient noise level and then ignore it

idle owl
#

to quiet when I reset it

onyx hinge
#

can I get back to you in about 15 minutes? I will actually go home and be at my own set-up (which again is nRF, not samd)

idle owl
#

Yes.

#

Thank you.

onyx hinge
#

okay, talk to you soon

#

@idle owl OK I'm at my circuitpython desk now

idle owl
#

Ok

#

Maybe I deleted too much code?

onyx hinge
#

meanwhile I'm trying to get mine plotting on mu and showing on LEDs..

#

so this does graph in mu for me while also showing the bar graph, but the scaling of the graph is not great

#

plotting "c" instead of "magnitude" seems better, because even very loud noises don't change the autoscaling so much that smaller noises can't be seen anymore.

#

now let me pull down your code..

idle owl
#

How is that even working for you, you're using the 2.x setup line?

onyx hinge
#

I ... don't know?

idle owl
#

Weird

onyx hinge
#

I think I changed the line and didn't change the comments

idle owl
#

Ah

onyx hinge
#

it does use sample_rate as described for 3.x...

idle owl
#

ohhhh y

#

Yes you did

#

nm πŸ™‚

onyx hinge
#

OK, I so I took yours and I ONLY changed the pin assignments and it does work on my nrf board

idle owl
#

hmm

#

you're getting reasonable data?

onyx hinge
#

yes I get data that changes a little bit all the time, and if I talk loudly it gets more, and if I clap it gets a LOT more

idle owl
#

then it must be something with ambient noise in here borking the initial reading.

#

ugh.

onyx hinge
# 
    print((magnitude,))
``` I also made this change so that it plots in mu
idle owl
#

Right, I just did that too

#

But right now I'm typing which is loud and it's reading 0.0

onyx hinge
#

no, that can't be it either, because input_floor is computed but never used

#

it is used by log_scale, which is removed in your version

#

or, sent in to log_scale

idle owl
#

oh

onyx hinge
#

I am sure you did it already but do you want to double check your connections?

idle owl
#

yes I do want to do that.

#

it's CLOCK, DATA right?

#

the pin order in the code

onyx hinge
# 
                       sample_rate=16000, bit_depth=16)
``` well it's what *I* have written here
#

class audiobusio.PDMIn(clock_pin, data_pin, *, sample_rate=16000, bit_depth=8, mono=True, oversample=64, startup_delay=0.11)

idle owl
#

Oooooh I had my clock and data reversed

#

Bonus.

onyx hinge
#

oookayy any difference?

idle owl
#

I guess I'm getting slightly more reasonable data?

onyx hinge
#

something else to be aware of, I often find that "short" sounds just get missed, I guess because it records sound, then does math on the sound, then prints the value, and then records sound again

idle owl
#

Oh. Good call

onyx hinge
#

so if you can just sing or hum it's actually better than clapping, once you think it's registering noise at all

idle owl
#

Ok I'll try that in a second

onyx hinge
#

Is there a way to pause the mu graph ? I guess I can just ctrl-C my code to stop it

idle owl
#

Yah

manic glacierBOT
onyx hinge
#

printing "magnitude"

idle owl
#

Ok yes.

#

Making longer noises at it works

#

Oi, thank you so much

onyx hinge
#

you're welcome

idle owl
#

Good info for the guide as well, the short sounds thing.

onyx hinge
#

you are on an M4 board, correct?

idle owl
#

Yes

#

Feather

onyx hinge
#

OK

#

seems like the guide, or the docs, need to make a list of board.Dxxx which can be used for CLK and DATA on M0/M4 as well

#

It may be related to which pins can be used on SPI, I was getting an impression from the source code, but not sure

idle owl
#

I have a program I can adapt to spit out the allowed pin combos

#

If I didn't already write one for this.

onyx hinge
#

oh cool -- how does that work? Just try all the possibilities?

idle owl
#

Yep, try to instantiate all of them, and then split out a list of valid combos

#

I wrote it for SPI, UART and I2C I believe

#

accounts for duplicates and the weird pins in pins.c

#

like NEOPIXEL and so on

onyx hinge
#

that is a good double check for developers too

#

if it's not uploaded somewhere, it should be

idle owl
#

They're all posted in the CircuitPython Essentials guide.

#

cool, there is so much documentation I haven't even found yet

It appears to be modified only in audio_dma_reset and audio_dma_background. is audio_dma_background actually reached from an interrupt or similar?

@onyx hinge I think because of this:

        // audio_dma_load_next_block() can call Python code, which can call audio_dma_background()
        // recursively at the next background processing time. So disallow recursive calls to here.
        audio_dma_pending[i] = true;
        audio_dma_load_next_block(dma);
        audio_dma_pending[i] = false;
#

audio_dma_pending[i] is checked at the top of that routine, to avoid the recursive calls. Sometimes background tasks are called recursively during background tasks

onyx hinge
#

@tulip sleet hm okay, I will try to wrap my head around that -- it doesn't seem like a place it would have occurred to me to specify 'volatile'.

# 
>>> s = audioio.RawSample('\0' * 8)
>>> a.play(s)
allocate channel 0
>>> a.deinit()
>>> a.play(s)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: Object has been deinitialized and can no longer be used. Create a new object.
>>> a = audioio.AudioOut(board.A0)
>>> s = audioio.RawSample('\0' * 8)
>>> a.play(s)
allocate channel 1
``` also, this is not good (debug statement is reporting DMA channel allocation; deinit failed to force the deallocation of the existing channel.  So my added channel allocation tracking is ... incomplete.)
#

but that's all I've got the steam for tonight. see you all later

tulip sleet

if the compiler deferred writing to memory, then the check at the top of the routine would have a stale value. np, ttyl

[adafruit/circuitpython] Pull request opened: #2088 Swap the CI to GitHub Actions from Travis

Here is a normal test build: https://github.com/tannewt/circuitpython/runs/205207009

It failed on S3 upload because my repo doesn't have the secret set.

The release uploads are working but got rate limited: https://github.com/tannewt/circuitpython/runs/205075094 Theoretically we can squeeze under the 1,000 request limit of the repo token with a single release but we may need to use a separate token if not.

I have a couple thoughts, but I don't think they warrant holding this up:

  • Break the workflow and actions into separate files. Scrolling down through 72 builds is cumbersome. And while all of the builds are technically ARM, grouping them by chipset (like the ports directory does), might be more intuitive. It wouldn't necessarily require duplicated code all over the place, if I'm reading the docs correction. The meat of the build can be placed into a .github/actions/build_board.yml, and ...

#

@prime flower -- I'll have to think about it but my initial reaction is to take it all out and if we want to support anything with the AT control, it should only be for the particle Argon.

prime flower
#

@solar whale ok let me know what you decide

solar whale
#

@prime flower OK --I'll try to look at it later today and do some testing on an Argon -- it's been a long time since I tried anything new ( I have some old code that has been running for many months on an Argon) I will verify that it is not broken as is then review what capabilities it lacks. Do you want to have an "argon-AT" section in this guide? Or should it be a separate guide? I think we should discourage anyone from using the ESP8266-AT firmware.

prime flower
#

@solar whale Considering there's a section for ESP32/ESP8266, it'd be ok to add an "Particle Argon"section to the guide. Let's keep it organized by board.

#

thanks for doing this, I came across an older TODO and want to clear it. it'll help keep the circuitpython iot ecosystem up-to-date πŸ™‚

solar whale
#

Do you still want to support esp8266-AT or ESP32-AT other than Argon? Why?

prime flower
#

@solar whale I'd prefer to only support ESP32 via ESP32SPI, and AT only with argon. Do you agree?

solar whale
#

yes

prime flower
#

Ok. I'll make a note to self to ask ladyada if she wants to support ESP8266-AT. I don't support ATControl in MiniMQTT/Requests, but could if we're going to continue supporting it.

#

Ideally we'd support NetworkManager-style objects like WiFiManager.

solar whale
#

OK -- I have to get up to speed on the MinitMQTT -- It will be interesting to see just how far we can get the ARGON-AT to work

prime flower
#

I want to do networkmanagers for Ethernet/LoRa/Cellular/etc...

#

MiniMQTT should handle multiple network managers with a bit of editing

solar whale
#

Great - the Argon is a nice package so it would be fun to keep supporting it as long as it does not become too much of a burden on the other libraries. The main thing will be to clearly identify its limitations. Thanks for the prompt to get back to looking at it.

@solar whale the main limitation would be the lack of space for larger libs like CircuitPython_RSA

tulip sleet
#

i could do the release on friday if you're away

slender iron
#

kk, the github ci stuff should work

tulip sleet
#

@slender iron and anyone else: API style question:
I used to do:

# style A
char = Characteristic(<Characteristic creation args>)
serv = Service(characteristics=(char,...), <other Service creation args>)
periph = Peripheral(services=(serv,...), <other Peripheral creation args>)

But there actually shouldn't be unattached Characteristics or Services. They should always be created and immediately attached to a parent Service or Peripheral. Also they shouldn't be attached twice. I had to validate these kinds of things internally. I changed this today to:

# style B
periph = Peripheral(<other Peripheral creation args>)
serv = periph.add_service(<other Service creation args)
serv.add_characteristic(<other Characteristic creation args>)

So these are sort of factory methods that create the object and immediately add it. There are no longer visible constructors for Service or Characteristic, and you can't create an unattached one. But you no longer see the class name explicitly (well, it's just lower case). Note this is instead of, say:

# style C
serv = periph.add_service(Service(<other Service creation args))

where you have an unattached service for a brief time. This is actually quite common in other BLE APIs.

Alternatively the API could be:

#style D
periph = Peripheral(<other Peripheral creation args>)
serv = Service.add_to_peripheral(periph, <other Service creation args>)
char = Characteristic.add_to_service(serv, <other Characteristic creation args>)

I think I am just bothered that the names in style B are not add_Service, etc. But that's just kind of a PEP 8 limitation. The second example is cleanest, I think. Maybe I have answered my own question.

slender iron
#

@tulip sleet I think style B is fine. can you then get them all through .services and .characteristics properties too?

tulip sleet
#

yes, there's always available. I agree, it's probably the safest and the most straightforward. One thing that came up is that any subclasses of, say, Service, which might take different args, can't be added easily, because Peripheral knows the args to Service. But I got around that with something like style D for the subclass, so there's a ServiceSubclass.add_to_peripheral(periph, <ServiceSubclass creation args>). And in fact it's not really a subclass, just a convenience wrapper.

#

this is all in bleio anyway, so the average user doesn't see it

#

and the change from A to B did make the C code a lot more straightforward in various ways: no deferring of necesssary operations until a secret time later

I still like the idea of it being more declarative

where the peripheral subclass has class level attributes for each service

tulip sleet
#

@slender iron not sure what you mean, because i wanted a service subclass (e.g. a common predefined service that might be used in several places, like say BatteryService)

#

it's a wrapper for creating a service with certain characteristics

#

because a Peripheral can add more than one service

slender iron
#

right, I imagine that would happen by making a class for it and having attributes on it

tulip sleet

right, at the user level, in python, this is just the lower level. Like , UARTServer, and CurrentTimeClent have attributes that are natural to use

#

@tulip sleet Regarding Style B, how do you propose the API for removing a service /characteristic would look like?
Something like this?
serv.remove_characteristic(characteristic_uuid)

tulip sleet
#

@subtle sun Service.add_characteristic() returns the created characteristic, so you could just pass that back in. However, there is no removal API in the underlying Nordic softdevice, so I can't provide one in Python.

tidal kiln
subtle sun
#

@tulip sleet Is there a way of restarting the whole ble stack?
Might be worth holding on to the object tree of the services so you can allow dynamic removal

tulip sleet
#

bleio.Adapter.enabled = False disables the softdevice, but it also cycles the USB hardware. I think dynamic removal is rare, and would rather not add it if not necessary. You can always shut down a peripheral and create a new one

We are trying to cover the most common functionality.

Service, Characteristic, and Descriptor now are created via a factory classmethod, which takes their parent object:

service = Service.add_to_peripheral(peripheral, uuid, ...)
characteristic = Characteristic.add_to_service(service, uuid, ...)
descriptor = Descriptor.add_to_characteristic(service, uuid, ...)

[adafruit/circuitpython] New review comment on pull request #2092: Bleio attribute api revamp

I don't like switching to a factory pattern for this because it divorces the documented service from it's implementation. The device information service example is a perfect example of this. It's documented as a specific service but returns the generic implementation bits.

I think it'd be simpler and clearer to simply add parent_service to the constructor. I'd add parent to the name to make it clear what the relationship is. This can apply to Service, Characteristic and Descriptor as well.

I feel the ESPTool vs MiniESPTool passhthru should be discussed somewhere

solar whale
#

agreed -- and miniesptool is the only way to program the Argon anyway.

#

I think a new guide for configuring/updating ESP32SPI (with a special chapter for Argon-AT) would be good -- Then all of the board guides can point to it - it can cover using Passthrough, ESPTool and miniesptool. For most of the new Airlift/Pyportal boards since ESP32SPI is installed, it would just be for upgrades. Do you also want to support guiding someone starting with an ESP32 Huzzah or other board that does not have ESP32SPI on it yet?

I'm assuming this guide is only for programming/updating the ESP32 -- not for using the various libraries that are now available.

[adafruit/circuitpython] New review comment on pull request #2092: Bleio attribute api revamp

I did try this, but it then creates anonymous constructors that don't actually need to be assigned to anything. Here's an example. char1 has a fixed-value Descriptor which doesn't need to be referenced once it's created:

peripheral = Peripheral()
service = Service(peripheral, service_uuid)
char1 = Characteristic(service, char1_uuid, ...)
Descriptor(char1, desc1_uuid, ..., initial_value=xxx)

So there we have a constructor with no assignment to anything, because we don't need...

@slender iron OK, fixed that delay by putting the inner refresh at the top of the loop. There was two refreshes called back to back at the end of the loop so the second one waiting

#

Now I'm getting the desired behaviour

slender iron
#

πŸ‘

#

do you actually want the outer refresh? won't that cause the animation to skip a frame?

idle owl
#

@tulip sleet Time for a quick look at a piece of code? I want to make sure I can't get it any simpler than this. I think I stripped out as much as I could, but you worked with the original, so you might know better than me if I left something in.

tulip sleet
#

sure

idle owl
#

Meant for plotter

slender iron
#

@umbral dagger try using a bunch of tilegrids instead of one

tulip sleet
#

@idle owl

    samples_sum = sum(
        float(sample - minbuf) * (sample - minbuf)
        for sample in values
    )

two things: could calculate sample-minibuf just once in a temp var, and why is there a float() on one of them?

idle owl
#

I have no idea. I stripped down the CPX Sound Meter code, I don't really know how it works on the inside.

slender iron
#

@umbral dagger by using one big tilegrid you are refreshing the entire screen each frame. use a bunch of small ones and you'll only refresh where they are

idle owl
#

@tulip sleet I also notice in the CPX Sound Plotter guide, the mic is initialised before the main loop, is that necessary? I no longer have that in the code I sent you.

tulip sleet
#

oh , I remember, because the samples are ints so I want do do float arithmetic instead of integer arithmetic. I can force that by just converting one of the operatands to float

#

i forgot the samples are ints

slender iron
#

@umbral dagger the real refresh takes over a second: ```
inner 0.0 False
inner 1.153 True
inner 0.0 False
inner 1.153 True
inner 0.0 False
inner 1.153 True
inner 0.0 False
inner 1.15299 True
inner 0.0 False
inner 1.153 True
inner 0.0 False
outer True
inner 0.0 False
inner 1.153 True
inner 0.0 False
inner 1.153 True
inner 0.0 False
inner 1.153 True
inner 0.0 False
inner 1.153 True
inner 0.0 False

idle owl
#

(Admission: I totally forgot to check the CPX sound plotter guide to use that code, so I manually stripped out all the neopixel related code from the sound meter to get this code when I could have gotten it from that guide. 🀷 )

#

@tulip sleet I'm only partially following what you're suggesting.

slender iron
# 

        t = time.monotonic()
        result = display.refresh(target_frames_per_second=1)

        print("  inner {} {}".format(time.monotonic() - t, result))

(sample - minbuf) is arithmetic on two integers so it will stay an integer. Multiplying two integers and then adding a bunch of them up will either overflow small integers or become a long int, which is expensive. So I convert one of the integers to a float, and that forces all the results to be floats in that expression, so I end up with a floating point result @idle owl

idle owl
#

Ah hmm ok

tulip sleet
#

so like (65535 - 0) * (65535 -0) is a large number, and then that added up many times might overflow a small int

#

actually it's already too big even just 65535 * 65535 just once

idle owl
#

Fair enough.

manic glacierBOT
tulip sleet
#

so anyway the code looks fine @idle owl ; i'm critiquing my own code

idle owl
#

πŸ˜„ Ok.

#

Do I need to init the mic before the main loop?

#

Or is that fine in this case

slender iron
#

@tulip sleet want to chat ble api?

tulip sleet

yah, in a couple mins, will ping you

Was curious if you were passing only the socket into set_interface or the esp as well

then I just had to create a dummy settimeout() in adafruit_espatcontrol_socket and define TLS_MODE and TCP_MODE in adafruit_espatcontrol -- that was about it.

[adafruit/circuitpython] New comment on pull request #2092: Bleio attribute api revamp

@tannewt and I talked about the structure of the API extensively. I understand his desire to describe a service in a declarative way in a class, with attributes or dictionary lookup for characteristic values. We agreed that is a goal, probably done first in Python and then possibly moved to C.

Because the native module API will continue to evolve, we are renaming bleio to _bleio to discourage its everyday use, and to allow it to change incompatibly between minor versions of CircuitPyth...

@tulip sleet does that prevent PDMIn from bring available too (no i2s on Sam d51)?

#

It seems problematic that you have to have both or neither (or you can implement stubs that throw NotImplemented type errors)... I2s and pdm are really not very closely related other than by placement in audiobusio

@onyx hinge I'm ok if you want to split them apart. I thought they'd be closer together since samd had them that way
