#

the slideshow worked fine for me with current master

tulip sleet
#

yes

#

the slideshow will fail if you try to write to the drive while it's running. It gets stuck in the background loop when there's a reload pending (due to a file write).

#

that's what Limor saw (she was updating code and/or pics while it was running).

solar whale
#

ah -- OK -- I wonn't do that! I'll pull 1604 and see how it works

tulip sleet
#

#1577 may be a different problem

solar whale
#

I also changed the SD mount to use board.SPI() otherwise it complained when it created the display device

tulip sleet
solar whale
#

I was using slideshowf -- did not have slideshowsd

#

it had commented out lines for sd

tulip sleet
solar whale
#

was taht for pyportal -- it uses board.DISPLAY

tulip sleet
#

yes

#

you're using the TFT Featherwing or equivalent?

solar whale
#

yes -- just testing it

tulip sleet
#

i started with that but couldn't get it to break :), so I just waited for my pyportal to show up

solar whale
#

it was going great until I tried the SD card 😉

#

still fails with 1604

if you can get a reproducible problem with 1604, that will be very helpful! I didn't see the #1577 problem at all. I'm using a 4GB card; what are you using? (brand and size)

solar whale
#

8GB sandisk -- it works fine if I just mount it and read from it

#

as you can see it reads the file list

tulip sleet
#

did you prep the card with images on the host computer?

solar whale
#

I'll play with it a bit more and add to the issue or PR

#

yes

tulip sleet
solar whale
#

works fine from the Flash drive

#

np -- I'll look over the issues and see if I have anything new to add. Sorry I did not review them first.

tulip sleet
#

try reformatting the card on the host and copying the images fresh. That's the only thing I can suggest.

solar whale
#

I did that once already...

#

fat 32 is OK,

#

right

tulip sleet
#

yes

solar whale
#

thanks -- I'll keep trying -- have to go do some errands first

@pastel panther That's what's confusing me. I can't find those pin defs anywhere, but example code for PyPortal and Feather M4 use those constants, and they work. Not sure where they're coming from.

tulip sleet
#

But we shouldn't have to have regular users read the source code, so if you see omissions in the Learn Guides, please let us know. Thanks!

crimson ferry
#

Thanks! Found the ESP_ control pins in PyPortal pins.c, but I don't see them for Feather M4 even though examples use them. The original thing I was wondering was whether those pin defs should go out to all Express boards since any of those could be used with ESP32SPI. Minor thing, but consistency in docs and example code. Or maybe that's not the right place for them, and pin numbers should be the order of the day.

tulip sleet
#

@crimson ferry The ESP is just one example of something that could be connected to the SPI pins on any board, so we wouldn't make up specific pin names for a specific SPI device. If there are Feather examples that use the PyPortal pin names then that's a mistake; le us know.

crimson ferry
#

Thanks, much ado about nothing I think. Some examples sent me down a rabbit hole. I'm on the learning curve and asking a lot of questions. I shouldn't go mucking about in libraries at this point, but I'm happy to help tweaking docs, examples, etc. if that's of interest (just need to figure out the process).

pastel panther
#

@crimson ferry I just checked all the examples in the ESP32SPI repo and I agree with you that there is room for improvement there. They're not consistent (some refer to board.ESP_CS, others board.D9 for the same pin). Additionally none suggest what board they were written for or that they can/should be changed for other boards.

This is totally understandable because this is a brand new library that is still in active development by multiple people, however improving the docs will be helpful down the line.

#

also please do go mucking about in libraries! More eyes on the code from different viewpoints is helpful, especially the example code. We appreciate you voicing that they're a bit confusing!

thsi is what I use for a metro/feather_m4

crimson ferry
#

I use same for Feather M4 & ItsyBitsy M4

pastel panther
#

Tbh the 'wifi co-processor' guide could use some work in the esp32spi part as well. @solar whale is that something I can do?

solar whale
#

@pastel panther You may want to check with @meager fog but I'm sure any help would be appreciated. There is very little information now for the esp32spi setup.

#

also @gilded cradle has been quite involved with it.

pastel panther
#

It seems like things are stable enough in the libs for that to be warranted, ya?

solar whale
#

I think so -- the hardest thing is deciding waht demos to document! also it ties into wifimanger and adafruit-io

#

but it is stable and working quite well at this point.. a few open issues but no biggies.

pastel panther
#

I'm going to see if I understand displayio enough (and the code's there) to get a little wifi signal strength indicator going from rssi/signal_strength

manic glacierBOT
crimson ferry
#

Best examples for displayio are the Hallowing guides?

manic glacierBOT
pastel panther
#

@crimson ferry There aren't any great examples yet. This one is the one I just submitted a PR for but it assumes a built in display like a PyPortal or Hallowing:

📎 code.py
#

this is the only other one I'm aware of at this point and it requires an ILI9341 screen. It may have some bugs as well

#

In that example Sprite should be TileGrid

#

tbh displayio is still alpha-ish at this point. Anyone venturing into that territory is advised to bring a machete and snake bite kit

prime flower
#

@pastel panther I eagerly await your RSSI meter. Are you going to do it with multiple BMPs or render it differently?

crimson ferry
#

Thanks. I eventually want to be able to mirror, as closely as possible, what I display on PyPortal, TFT+mho touch, and even ePaper 😉

pastel panther
#

I think TileGrid is named such that it can allow you to keep a map of bmps in a single bmp, so I'm going to look in that direction. If not I'll probably just have several mono bmps

#

Glyph may have a part here too

#

@crimson ferry it's totally doable; it's what I did before I got my PyPortal

prime flower
#

I'm trying to figure out a good animation for "sending data to IO" on the display

#

maybe spinning the adafruit logo when its sending data would be fun

pastel panther
#

that would be cool. Aseprite is a great tool for such things

prime flower
#

Oh, that looks awesome

pastel panther
#

definitely worth the $15

Going to download the trial and see what I can do with it, looks ideal though thanks!

meager fog
#

@pastel panther @solar whale the reason esp32spi isnt documented fully is the feather is kinda overkill board to use, was going to replace with the minimal breakout coming out soon

#

like, next week

pastel panther
#

😃

solar whale
#

@meager fog That's great! I was hoping for such a board! WooHoo!

meager fog
#

kk

pastel panther
#

heeey @meager fog how about a ESP32-WROVER-IB or similar breakout with an external antenna hookup?

#

perhaps it's a bit late to ask for such a thing if there is already one coming down the pike

meager fog
#

yeah we can place any module

#

ill get there 😃

pastel panther
#

😃

#

is the new one a wrover or wroom?

meager fog
#

wroom, wrover is the PSRAM one right?

#

leme get u pix

pastel panther
#

wrover is the longer one

meager fog
#

yeah thats not useful

#

its $$ for nothing

pastel panther
#

nice

meager fog
pastel panther
#

mmmm... yum

#

I thought there were other differences other than the wrover being longer but maybe not

solar whale
#

Will we load code via "passthru" or via TX/RX or either?

#

I assume it will ship with NINA_W102 installed

meager fog
#

yeah

#

and you can load code with tx/rx/gp0

#

@pastel panther the wrover is longer cause of PSRAM, but WROOM has a version w/uFL

I'm drooling over here. Feather Huzzah32 gets you the battery & charger, but smaller and less $ is... 🎉

umbral dagger
#

@meager fog I've been excited to get my hands on this. A little less-so now that the PyPortal is out, but there are tons of non-screen IoT applications.

meager fog
#

yay

#

yah now that the software is solid and tested, we can kick off a lot of iot things - metro wifi n more

#

mostly had to waste my time figuring out which implementation to use

pastel panther
#

@meager fog do you have a sense of how resource strapped the esp32 is with the NINA firmware going full bore? It seems like there might be spare capacity there but I'm not really basing that on anything

meager fog
#

plenty left

#

i think it has one core just for wifi, one for SPI

#

its barely doing anything

crimson ferry
#

I have an army of arduino 8266 huzzah & feather IoT devices, but I really want future ones to be CP+WiFi, so this is awesome, more choices for form factor, etc.

meager fog
#

im curious if ESP8266 could be adapted to run the SPI code - its possible i think

[adafruit/circuitpython] Issue opened: #1612 displayio and SPI conflict

There appears to be some conflict with displayio and SPI.
I have a TFT featherewing on a Feather_m4_express ( same issue on a particle xenon)
and if I run the stmpe610_simpletest which reads the TFT touch screen it works normally as long as I have not configured displayio first. If set up diaplayio -- so the REPL is being echoed to the screen, and then try the stmpe610_simpletest, it crashes.

PR #1604 had no impact on this -- it behaved the same with or without it.

[adafruit/circuitpython] New comment on issue #574: Update Intro guide to include PyCharm MicroPython REPL

I removed the page because it never really worked properly. It was inconsistent and for me, at least, required deleting all of my settings to get it to work each time. It was never designed to work with CircuitPython, it was designed to work with MicroPython, so it provides a lot of features that are irrelevant to CP such as flashing the board.

If you wish to access the REPL from PyCharm, consider using the built in terminal and screen to connect to the serial console/REPL.

what is the 3rd element in the proxy for? I know the first two are get/set.

    .proxy = {(mp_obj_t)&displayio_ondiskbitmap_get_height_obj,

              (mp_obj_t)&mp_const_none_obj},

from py/objproperty.h:

typedef struct _mp_obj_property_t {
    mp_obj_base_t base;
    mp_obj_t proxy[3]; // getter, setter, deleter

that suggests a deleter

[adafruit/circuitpython] Pull request opened: #1614 Add frequencyio\.FrequencyIn

Its time again to try and get this in. Updates since #1144:

  • Instead of putting this in pulseio, this creates a new frequencyio to better manage inclusion/exclusion. Most of the smaller builds (M0 basic, CPX, etc) were exceeding flash size.

  • Now uses a single "reference TC" for interrupts/results calculation, and "capture TCs" for frequency sensing. This keeps the interrupts from flooding the MCU, but does eliminate 1 timer available for capture. I've had up to 2MHz input detected...

[adafruit/circuitpython] Issue opened: #1615 particle xenon safe mode with tft featherwing

I have been trying to use a particle xenon with a tft featherwing to test displayio.
In general, it works fine except that very often I on power up, the system goes into SAFE mode due to a low power condition. I have not seen this with the feather nrf52840 or feather_m4_express.

It usually recovers and boots normally if I just press RESET so it appears to be related to the power up.

Since the issue does not occur with the feather nrf52840 it appears it is due to the power supply on...

[adafruit/circuitpython] New comment on issue #1615: particle xenon safe mode with tft featherwing

hmm -- I tried adding delays from 2 to 10 ms and it made no difference but I found something else of interest. Grounding the EN pin on the particle_xenon only drops the 3.3V signal to 1V ?? It goes to 0V on a Feather_m4 (and I assume on all feathers) Both rise to 3.3 V in a few hundred microseconds but does the threshold test possibly get confused because the xenon is starting at 1V? In any case - having EN not working properly is troublesome. That is how the TFT featherwing controls power...

#

nope, it does not appear to. I think the pins are busy key matrix-ing and sensor-ing

exotic pumice
#

yeah, a contributor to atsamd-rs was wondering why GenericClockController::with_external_32kosc() wasn't working

#

that would be it

#

we have trellis support now

#

kinda

pastel panther
#

nice

exotic pumice
#

the neopixels are pretty broken but that's an external library to atsamd-rs

pastel panther
#

right. keep in mind it's also got the status dotstar on the back

exotic pumice
#

yeah, that's even harder to use

#

for me anyway

pastel panther
#

You would think it would be easier, having it's own clock 🤷

exotic pumice
#

it requires a bitbang-ed spi driver

pastel panther
#

sercoms not working yet?

exotic pumice
#

no, circuitpython uses a bitbang spi driver

#

the pins are backwards so you can't use a sercom

pastel panther
#

oh right

exotic pumice
#

that was a fun day

pastel panther
#

I remember now

#

aren't bitbanged SPI drivers relatively straightforward?

exotic pumice
#

kinda

pastel panther
#

I mean i'm sure you have plenty of other stuff to keep you busy

exotic pumice
#

I wrote a bitbang spi driver but didn't expect it to work

#

it's really slow

#

we got neopixels working first

#

"working"

#

which means flashing arbitrary colours rapidly

#

but all we really needed was proof the board was running our code

#

and not panicing

pastel panther
#

I mean, even random blinking is something to be proud of

exotic pumice
#

yup

#

also, another reason we went with neopixels is I don't have any boards with dotstars so I would be less able to help if the bitbang spi driver didn't work

pastel panther
#

sure, thats a good call

#

do you guys have a debugger working?

exotic pumice
#

I did, until my raspberry pi died, and the guy doing the neotrellis did not

#

after I wrote bitbang spi I tried to do bitbang uart rx, that's a nightmare

pastel panther
#

hm. are the neopixels using a sercom?

exotic pumice
#

I didn't think pa27 was a sercom pin

#

we're using a timer

pastel panther
#

you are correct, no sercom on pa27

exotic pumice
#

I forgot this had the "slow" feature

#

that might work

#

yeah it works

#

I think the trellis guy went to bed

[adafruit/circuitpython] New comment on issue #1615: particle xenon safe mode with tft featherwing

a few more observations:
I checked a particle argon and also found that the 3.3V only goes to 1V when EN is grounded.
Interestingly, when I did that, the argon rebooted to Safe Mode!

The Safe mode boot only appears to occur if the EN pin is used to power cycle the xenon board on the TFT featherwing. It boots reliably if I just apply power via the USB port.

I will post a question to the Particle.IO forum.

What's the expected price for the PyPortal?

yep! it does 'break' current code so FYI - the origin point is now at t he font Baseline not top-left bounding box corner

Last Week:

  • adabot:

    • added import checks for renamed ure, ujson, and uerrno modules.
    • updated -v command arg to ensure validate_contents is always run [first], so that bundles that are in-work are not included in validator results. Does not run/output full results unless explicitly included as a validator.

  • FrequencyIn: PR is in!

This Week:

  • circuitpython-build-tools:
    • Work on folderizing example files
  • adabot:
    • Look into library insights results showing zeroes

STATUS UPDATE Completed the mouth piece code for my midi ocrina. I am also going to build a mouth organ too.!

errant grail
#

Wrapped up the Range_Slicer CircuitPython library yesterday and am celebrating the successful completion of my first multiple-instance class today (with coffee and speculaas cookies). The class was derived from a synth project that needed to emulate a rotary switch with a potentiometer. It evolved into a general-purpose analog value converter that compresses or expands the input value then quantizes it into a collection of precise output slice values. The class detects input value changes and applies selectable hysteresis when slice edge thresholds are reached to eliminate noisy dead-zone issues, all without any internal delays in the code.
Applications include converting rotary knob position to MIDI control or note values, analog signal noise processing, as well as level detection and display. Have successfully tested up to 6 simultaneous instances with one of John Park’s projects and will be using it as the primary processing algorithm for a new Eurorack module.

#

Next step is to test it with 16 simultaneous instances on the Grand Central M4 Express board. I also want to try replacing the linear algorithm with some non-linear processes that could be used for things like decibels, dew-point, and pH. I may get distracted by using it to create a NeoPixel strip/array color organ with multiple analog inputs and overlapping color zones. No – Must. Finish. GitHub. Documentation. First.

I am trying to get my Jetson TX2 to run your Circuit Python libraries and am hoping to get some direction to getting the platform detect libraries to detect my board but I am having problems. Any advice will be great. Attached is a overview picture of our custom circuit that is running 4 or 5 Adafruit products that fall under your circuit python libraries.

I'm building this platform on a nodejs express server.

Thanks in advance for any advice.

autodoc_mock_imports, defined in conf.py, does a pretend import of the modules listed in it

#

are those your modules in your repo?

marble hornet
#

however i ram running sphinx locally

tulip sleet
#

could you push all this to a repo if you have not already?

#

it's hard to debug without seeing the whole thign

marble hornet
tulip sleet
#

trying stuff...

marble hornet
#

😃

#

doing bad things to microwave...

tulip sleet
#

there are two index.rst files: one is in docs, the other in tg_tui/tg_gui

#

there should be only one, in docs. In general I would say copy the layout of a an existing library, like BluefruitConnect or some other library that has multiple source files

#

that's not the problem, but it needs fixing

marble hornet
#

okay... do i need to point the make file to the ../tg_guil/index.rst

#

oh i see, it made them in docs

raven canopy
#

@solar whale i'm seeing it too, but a peak of 0.7V. on stock firmware, i don't even get the status LED with EN tied to ground. (which isn't surpising...)

📎 Capture.PNG
solar whale
#

Thanks for confirming.

marble hornet
#

but it is still giving me import errors

tulip sleet
#

@marble hornet you have separate .rst's for each file, you can use an api.rst instead. The main bug for "gui not found", etc., is that in the .rst file that mentions the module, it's listed as .. automodule:: gui, but it should be .. automodule:: tg_gui.gui, and same for the other modules.

#

that will fix the import errors, then that exposes other errors

marble hornet
#

trying...

tulip sleet
#

also, if programs is some examples, move it out of tg_gui and up one. also having both the repo and the module called tg_gui is confusing, and leads to tg_gui/tg_gui

marble hornet
#

okay, i can defiantly move examples to another location

tulip sleet
#

again, take a typical library as an example, and I think you'll be happy. sphinx is a lot of incantations, and it's good to start from a template.

#

if you want to be defiant, that's ok 😃

#

i have found it to be one of the least friendly doc systems I have encountered

marble hornet
#

I changed modules.rst to api.rst and removed the foobars.rst. however i am not seeing where the .. automodule:: tg_gui.gui goes as modules did not have automodule:: anywhere init

#

**in space it 😆

tulip sleet
marble hornet
#

awesome, it can;t find mem_free error, I'm guessing a try except would not work since it would run and still hit the mem_free?

raven canopy
tulip sleet
#

@marble hornet it doesn't know anything about what's in the gc module, so you need to autodoc_mock_import that

marble hornet
tulip sleet
#

yah

solar whale
#

@raven canopy interesting so the question is if that had an impact on the CP brownout detection. I missed that in the datasheet. Thanks!

@solar whale comparing the chip "power lines" between feather_52840 and the xenon, there is definitely some difference in how VDD & VDDH are routed. its beyond my abilities to decipher, but it stands to reason in my mind as a likely source for the differences in behavior.

marble hornet
#

@raven canopy is it the atsam that has the firmware choice of the busk-boot or linear or its it the nrf?

raven canopy

looking at the nrf sheet i have open rn, it appears it is hw only... but i haven't studied the power stuff enough to speak definitively. 😄

do dotstars work at any clock speed or?

iirc, there is a range, but they're more "forgiving" than neopixels.

exotic pumice

mm, datasheet says 800-1200KHz

#

My bitbang driver goes 420KHz when I tell it to go 3MHz lol

#

maybe if I tell it to go 6MHz it will go 800KHz

raven canopy
#

yeah, was just looking at that. that KHz unit is...confusing. 😄

exotic pumice
#

apparently it's quite common to run them upwards of 12MHz so the datasheet must just be a guideline

[adafruit/circuitpython] New comment on issue #1617: Trellis M4 Does not appear at tty device on chromebook

I tried on an older Samsung Chromebook, updated to the latest OS. It looks like you're running in developer mode or something like that. Could you confirm and describe what you're doing?

If dmesg is available, could you paste what's in the system log when you plug in the board? That will give us some clues about what the USB issues are. Thanks.

I would test the power first

I mean you said it looks like like a doornail, right?

Well it was working and I loaded an arduino sketch onto it and then reset and unplugged it and it stopped working after that

#

No lights whatsoever

can you get a bootloader drive?

#

Oh, just double tapped reset and am getting activity. That's good.

#

Whew. It's ok

😃

gilded cradle
#

Got the portalboot drive

#

Thanks

#

Just got worried and panicked a little

pastel panther

arduino sketches wipe out CP so maybe that was it?

I get it, been there

gilded cradle
#

Yeah, but there's no power light either

#

So it's a little confusing

pastel panther
#

ya, I don't think the PP has a led on the power rail

gilded cradle

yeah

I'm trying to get see if I can get it working with the thermalcam wing

fwiw if you have a jlink almost anything is fixable but fortunately that's not necessary

ooh, the older one did a thing

six white neopixels and a yellow

exotic pumice
#

just kinda glitchy though?

#

yeah

#

that's what the last guy that tried it got

the first version (not linked) was just colours glitching all over the place, the 2nd version was that, and the third version is as you say, no dice.

#

hmm

#

can you make an elf with debug symbols?

exotic pumice

why would it work on metro and not on trellis?

sure

err

I was going to say I have the other m4 boards but no swd on my trellis atm

kinda a lotta work though, I get it if you're busy

I guess I wanted to open the trellis case anyways to clean it 😐

#

(I'm not busy)

#

gimmie a few

exotic pumice
#

thanks so much

#

I wonder if the lack of crystal plays a role?

#

more unstable?

#

it might be good to measure clocks

pastel panther
#

I don't think so cause other adafruit boards have no crystal and can talk neopixel just fine

exotic pumice
#

the weird thing is the third version is as close to the adafruit code I can get

#

and apparently that's the one that doesn't work at all

wait why is that referencing sk6812?

pastel panther
#

I think it's a neopixel compatible

exotic pumice
#

ok

pastel panther
#

I think saleae had a neopixel analyzer ... one minute

#

it at least thinks you're sending data for all 32

exotic pumice
#

always good

#

it's hard to read this but that kinda looks like a brightness scaled down rainbow to me

#

can you measure frequency?

pastel panther
#

one sec

#

looks like ~ 630kHz

exotic pumice
#

supposed to be 800, eh?

pastel panther
#

I think so?

#

have you verified the clocks?

exotic pumice
#

on metro, not on trellis

#

trellis doesn't have a lot of gpio so idk if it's even possible

pastel panther
#

most of the pins are connected to something so there should be something to probe to; I had to grab onto a leg of the level shifter to get a trace of the neopixels for example

exotic pumice
#

ok

#

wanna find something you think you can probe marked GCLK/IO in the datasheet?

pastel panther
#

that's like every pin

#

you set the mode of a pin to put a clock out on a pin

#

mode M i think

exotic pumice
#

yeah, but only certain pins are capable of it

#

afaik

#

only certain pins are actually connected to the gclks I mean

#

and I gotta know which pin and which gclk

pastel panther
#

which clock?

#

there are a few pin options for each clock I think

exotic pumice
#

yeah, pretty much

#

I can do any one

#

other than 0 or 1 I guess

pastel panther
#

lemee see if there is a pin that would be particularly easy

#

you're not using the flash?

exotic pumice
#

nope

pastel panther
#

if you can use glck 4 or 5 that would be easy ish; PA10 or PA11 respectively

#

if not I can find something else

exotic pumice
#

those sound fine

#

DPLL0/10 = 12MHz

#

theoretically

pastel panther
exotic pumice
#

close enough

pastel panther
#

I think I gotta call it

exotic pumice
#

thanks for all your help

[adafruit/circuitpython] New comment on issue #1617: Trellis M4 Does not appear at tty device on chromebook

I was able to see the system logs via file:///var/log/messages. I don't see any errors, and ttyACM0 is mentioned in the logs when I plug it in, but it's not visible to BeagleTerm. I don't want to wipe this chromebook to enable developer mode, so I may try some other way (like putting CloudReady on a laptop).

I also tried the latest build of CircuitPython and it's still not working. It's not specific to the Trellis.

ah

you can look at same file in any other repo for general ref

umbral dagger

Yeah.. I just replaced the todo with the code.

pastel panther

@exotic pumice 👆 that was taken in slow mo. Methinks you got it but need some delays

the _slow version seems infinitely so. All the pixels are lit but not moving

@tidal kiln Any idea about the error now?

@pastel panther It has the same delay as my cpx rainbow. That's just what it does for some reason. The metro m4 works better with slow on but the trellis doesn't like it apparently. Thanks again for trying.

I wonder, is it a different brand of neopixel, with slightly different timing requirements?

pastel panther
#

Maybe? What are you trying to tell them to do?

exotic pumice
#

Rainbow cycle

pastel panther
#

Maybe try with something simpler to debug like r>g>b cycle with substantial delays. Maybe even just one pixel to start

#

Also try at half brightness

exotic pumice
#

This is actully supposed to be like 1/8th brightness but it's broken

#

I tried a red blink and it just blinked random colours

#

(on off)

pastel panther
#

Looking at the previously posted data I can see what you mean

exotic pumice
#

I think that was the rainbow cycle

#

But yeah

#

The colours are way off

pastel panther
#

I can try checking with my scope tonight further down the chain to see what they're doing with the data.

exotic pumice
#

Thanks

pastel panther
#

Do you have gpio working?

#

I mean you must

exotic pumice
#

Yeah

gusty topaz
#

@lime trellis that SAM32 board looks amazing. So it would be an M4+ESP32+datalogger in feather form factor?

pastel panther
#

Can you make a version that looks for presses on the stemma pins with one to send a single red pixel on then off, then the other to send two blue pixels on then off with a different timing?

#

Also you should make a video for the eevblog scope giveaway

exotic pumice
#

By press you mean input high?

#

I found a library for the actual keypad we could try

#

But that might just add complexity

pastel panther
#

Set the internal pull-up and check for low

exotic pumice
#

Ok

pastel panther
#

I would skip the keypad lib for now

exotic pumice
#

So sda and scl?

pastel panther
#

Perfect! I think those are the right pins, don't know the label->port mapping but I can check when I get back home

exotic pumice
#

pb8 and pb9

lime trellis
#

@gusty topaz yep! It's a bit longer than a normal feather, but the pinout is compatible with Feather Wings so you can use any existing boards with added hardware capability

I think that's the default?

meager fog

yeah but to select the different #

pastel panther
#

sure

meager fog
#

i think adjustable conversion time is also useful

#

i think for mode - you only need shutdown, continuous for both and triggered for both

#

and for alerts, expose the registers but don't wrapper them nicely

tidal kiln
#

@tulip sleet it looks like UF2's for radio feathers haven't been generated since alpha 3. is that expected?

gusty topaz
#

@lime trellis how much would it be to have it ordered from OSH park ? (ballpark)

tulip sleet
#

@tidal kiln I think we didn't generate them because the boards didn't come with UF2 bootloaders. We can change that back.

meager fog
#

since we have a guide on how to load UF2 i think lets do UF2s

tulip sleet
#

i'll fix the generator.

meager fog

@pastel panther ok does that sounds good? ^^

pastel panther
#

by "for both" you mean current and voltage?

tidal kiln
#

@tulip sleet awesome. thanks.

meager fog
#

yeah i mena i dont see a need to have a mode thats only one or the other

so the mode is either 'off' 'continuous' or 'trigger'

pastel panther

ok, that should be good for now. I'll ping you if I need any clarified

hi all, I just got my pyportal and am trying to run some tests against Adafruit IO, but I can't seem to load images via URL or from the device. All I see on the pyportal screen is text.

Is there a debug flag I need to unset?

(src with URLs for the versions of each package I'm using: https://gist.github.com/abachman/0fa524e7c4dd5c4ee0bd11213884a417)

Ok so the code is running at least... That's more what I was wondering was whether for some reason it wasn't even getting to your code.

yeah, seems to be running / communicating fine

What in your code is generating images though?

It looks like all you have is something happening if you touch the screen.

not sure what you mean

idle owl
#

Looking again, hold on

keen parcel
#

if I comment out the .fetch() command, I see "Set background to /background.bmp"

manic glacierBOT
idle owl
#

Ok I missed the fetch in your code. Sorry

#

Hmm. Let me hook one up.

keen parcel
#

are those built with some debug output flags set to default true?

idle owl
#

I don't think so, no. There's debug in the PyPortal lib but you have to set it. I set it to False by default

keen parcel
#

that is, it doesn't seem to be a problem with data

#

or reading files

#

it's just stuck in serial mode?

idle owl
#

Shouldn't work like that. Hold on, I'm loading libs. I haven't done anything with PyPortal yet so mine is empty.

keen parcel
#

no worries, I'm in no rush at all

#

built the image-formatter for IO but haven't had a chance to play with it, is all :D

idle owl
#

Ok it's running.

#

Bah, need an AIO ID.

keen parcel
#

I can't load images from the CIRCUITPY volume either

idle owl
#

Ok I switched to the quotes demo simply to see, and mine isn't showing the background image either.

#

Printing the quote, but it's not loading the background.

#

I did delete the font though, hold on let me add it.

#

Hmm the font file isn't in the guide.

#

Hold on. Getting the file.

#

I think there's an issue. Trying to troubleshoot it now.

#

@keen parcel Give me a couple of minutes here.

keen parcel
#

👍 take all the time, this is not a blocking thing

#

thank you for your help, too!

idle owl
#

@keen parcel Let me know if it works please! I think there's an issue in the latest release of that library, but I'd like your testing to confirm it.

#

trying now....

#

HEY!

#

I SEE A DOG!

idle owl
#

Hooray!!!

#

Thank you!

keen parcel
#

no, thank you

#

I'm still new to this world (circuitpython) but am so happy you all are coming into my world (adafruit io) :D

#

question: do I have to use the .mpy version of adafruit_pyportal, or can I load adafruit_pyportal.py into the lib/ folder on the CIRCUITPY volume?

tidal kiln
#

either

idle owl
#

@keen parcel The issue with the .mpys is that we need them on boards with limited space. The PyPortal has a lot of space. .py versions are fine.

tidal kiln
#

.mpy is a "compressed" .py, to help with space, but they are functionally equiv

keen parcel
#

cool cool. Are they like the .pyc files python generates elsewhere?

idle owl
#

I have the entire lib bundle in .py form on mine right now. If you run into space issues because you load a bunch of images or something, then switch to the .mpys.

#

I don't know what pyc files do. mpy strips out the docstrings and whitespace essentially.

The common_hal routines common_hal_displayio_fourwire_begin_transaction() and common_hal_displayio_parallelbus_begin_transaction() return true or false depending on whether they've successfully started a display transaction. However, their return value is never checked: the callers assume that once called, the transaction has begun, even though the start-transaction has failed.

For ParallelBus, it doesn't matter, because there's no contention, and the routine always returns `true...

#

Gotcha - BTW, I'm going to use this device to make a very loud point

#

Medicare/aid (CMS) defines a "Speech Generating Device" very clearly (code E2510)... it's priced at $7000+. I believe this device lets me create one that matches the spec for $55 + a case.

meager fog
#

y0w!

#

do you need a pushbutton demo

#

i have a soundboard

tough flax
#

It’s a weird thing. The spec says the device must not be a general purpose computing device and must be able to play synthetic speech and use scanning.

#

It says very little about the actual usefulness (screen size, memory etc)

#

Mainly because it was written in 2001 and the one revision was trivial

#

So, I like that the portal has everything needed to make a compliant device built in

#

I’m planning on leveraging open board format

#

Writing a gateway that converts and translates as needed and feeds down the files and data

#

Actually a button press example would help as would a library that unpacks zips 😃

@pastel panther my partner in crime on the neopixel library wanted your raw logic analyzer data, without the decoder applied

pastel panther
#

exotic pumice
#

thanks

pastel panther
#

It looks like I didn't save it but I can get you some in a few hours

exotic pumice
#

ok

#

you seemed knowledgable about gclk/io. Do you know what happens if you have output enable set but aren't using pin function m?

#

because I noticed the neopixel pin is connected to gclk/io 1, and gclk1 is the 32KHz oscillator

split ocean
#

Anyone here with a PyPortal familiar with using the local.txt file to spoof JSON data?

pastel panther
#

@exotic pumice DS says "set a pin to mode M first" but didn't say what would happen if you didn't, as far as I can tell

exotic pumice
#

hrm

#

I guess I could just check on the metro

pastel panther
#

are you wanting to output the crystal to the neopixel pin?

exotic pumice
#

nope

#

I think I may have done so accidentally

pastel panther
#

I mean the 32k osc

#

(not sure it's a crystal)

exotic pumice
#

and it's interfering with the signal

#

idk just a theory

pastel panther
#

I don't think it's possible to use a pin for gpio and output a clock to it

exotic pumice
#

ok good

pastel panther
#

at the same time at least

#

since the modes are mutex

#

I don't know if it will be helpful but ben heck had some recent videos that involved clocking neopixels. It was mainly about getting hardware to do the heavy lifting for you but there might be some nuggets of wisdom there

exotic pumice

I watched that

#

Hi @split ocean , I just looked at the code and it looks like you just put your JSON data right in the file.

It looks like you need to do a fetch() and then call the json() function on the result.

I just put

@meager fog a bit of weirdness in the SoundBoard... if you change buttons, it plays right away - if you stay on the same button (tap... tap..) it doesn't replay until you wait a while.

#

Found it, @meager fog

while True:
    p = pyportal.touchscreen.touch_point
    if p:
        print(p)
        for b in buttons:
            if b.contains(p):
                print("Touched", b.name)
                if currently_pressed != b: # don't restart if playing
                    pyportal.play_file(cwd + "/" + b.name,
                                       wait_to_finish=False)
                currently_pressed = b
                break
        else:
            currently_pressed = None
    else:
        currently_pressed = None
    time.sleep(0.05)

Added the second "else" clause to clear the currently_pressed if there is no touch at all. Probably a more elegant way to do it, but this covers both cases, touching an area without a button and not touching anything.

If anyone has the command line for ffmpeg to convert into an acceptable WAV file for the portal, I'd appreciate it. I've gotten Amazon Polly to generate my text-to-speech (OGG) and converted that into WAVs that work using ogg123. However, I need to amplify each file, and ffmpeg can do that as a filter (I've listened in Audacity to the result), but the PyPortal dies with

Traceback (most recent call last):
  File "code.py", line 52, in <module>
  File "/lib/adafruit_pyportal.py", line 487, in play_file
ValueError: Data chunk must follow fmt chunk
#

I'm headed to bed but am very happy with the progress 😃

I just learned about the SSD2805 chip — that opens up a whole new batch of awesome displays

#

@tough flax I think I successfully used sox to generate the files I needed

#

if you search adafruit of sox, there should be some examples

Hi all. Im all new to python, arduino and everything around it. Trying out Mu-editor and CircuitPython but i get the message that I need to flash my device with CircuitPython. Is it possible to flash and use it on an Arduino UNO?

@raven canopy If you feel like another test on your XENON -- I noticed on mine that with EN grounded, if I apply power (plug in the USB) the 3,3V goes up to ~.7V as you saw, but if it then unground EN it goes to 3.3V and if I reground EN it goes to ~1.2v and stays there. I also observed tif I remove power (unplug the USB) the 3.3V drop to ~.5V and very slowly decays. I can force it 0V by grounding the 3.3V pin.

@solar whale that regulator is weird

raven canopy
#

@solar whale I can run that later. Suspect it will just confirm what you're seeing. I briefly tried to scrape through the nRF code to spot where BOR is handled, but couldn't locate it. I can try some more, but I imagine Dan knows exactly where it is. nrfx is muuuch different than ASF4. 😄

#

@raven canopy No rush -- I've lost most of my hair already....

pastel panther
#

lol

solar whale
#

interesting note from the particle.io forum -- If I use a lipo to power it -- I only see .46V when EN grounded.... confirmed bu another user there.

raven canopy
#

I read that. I can only assume it has to do with the charging circuit in the path...

solar whale
#

That's what I was thinking. I think I'll use my feather52840 with the TFT featherwing going forward.

#

very clean 0V or 3,3V on it

#

thanks @gilded cradle I thought that was the case. I had it working w the Quote.py Learn Guide example, but the OpenWeatherMap one isn't happy about it.

#

@solar whale where did you see the '.8v when CE low' info in the datasheet? I found one diagram that seemed to say that but I thought it was talking about the voltage that would be seen by the regulator as low (first diagram, page 22)

gilded cradle
#

Ah, ok. That one's a little finicky. I think it actually does a call to weather and another to get the time and that might be the issue.

#

I have to look to be sure though.

split ocean
#

I love these descriptions it provides Heavy intensity rain 8:14 AM

solar whale
#

@pastel panther I think I am just misunderstanding the output voltage range -- it is .8 - 3.6 V -- I saw and got confused by that figure on page 22 as well

gilded cradle
#

Yeah, it looks like the issue is that the get_local_time() function in PyPortal doesn't do a normal fetch

@gilded cradle this is the error I get code.py output: Set background to 0 No SD card found: no SD card Set icon to /weather_background.bmp Getting time from internet! Traceback (most recent call last): File "code.py", line 52, in <module> File "code.py", line 48, in <module> File "/lib/adafruit_pyportal.py", line 513, in get_local_time File "/lib/adafruit_pyportal.py", line 604, in _connect_esp AttributeError: 'PyPortal' object has no attribute '_esp'

gilded cradle
#

Yeah, like I thought, it's get_local_time() causing the problem

solar whale
#

BTW -- you can use "id" instead of "q" to select a city then use the CITY ID -- not the City name -- taht avoids duplicate city name confusion.

gilded cradle
#

It's doing a call through the ESP wifi manager and not looking at the localtime.txt file

solar whale
#

I also tied "zip" and my "zipcode,us" and got a city nearby, but not quite right.

split ocean
#

Oh, I only have a local.txt w the fake JSON, should I add a localtime.txt as well?

gilded cradle
#

Let me see if there is even a mechanism to bypass that

split ocean
#

Thank you!

#

@solar whale nice, I was wondering about that. Poughkeepsie is easy, but "Springfield, US" could be a bit of an issue :)

solar whale
#

I'm in Durham (NH) but there are many.

split ocean
#

LOL I imagine there's a big difference between your Durham and the one in NC as far as weather goes.

solar whale
#

Sure is!

timber mango
#

Is anyone is YouTuber

gilded cradle
#

Hi @split ocean , it looks like the trick is to just not call pyportal.get_local_time() in the openweather code

#

Let me see what would be the best alternative.

split ocean
#

@solar whale I just tried that by using a zip code in the LOCATION variable in the openweather.py file and it works very nicely, thanks for that.

solar whale
#

@gilded cradle are you having a problem with the openweather?

gilded cradle
#

Since the time won't be correct (no internet), it might be best to just do a print(time sting) with time string being whatever you want it to say.

split ocean
#

@gilded cradle OK, thanks. I don't need to have this be very elegant, I don't plan to include it in the guide, but it'll make it much easier to document the build by showing different data on the screen, not just the actual weather at the time.

gilded cradle
#

Not me jerry

#

Yeah, it appears to fetch the current time from the internet and print it out. Since you're trying to do it offline, I would just not call that one.

split ocean
#

huh, if I comment out lines 48 and 49 in openweather.py it still seems to be displaying local time on the PyPortal.

gilded cradle
#

Yeah, I think it just takes whatever it was last updated to.
