@slender iron I'm using kdiff3 for merging. It has mostly been the best for me, but has a few quirks. Just curious - what do you use?
tulip sleet
tnx - you are dedicated; I'll keep going with kdiff3 - resolves a lot of stuff correctly the first time
slender iron
ok @tulip sleet
@sick creek they are breakout boards we sell for playing sound files

@slender iron
Seeing various differences in exception raising:
"memory allocation failed, allocating %u bytes", (uint)num_bytes);```
vs
``` nlr_raise(mp_obj_new_exception_msg_varg(&mp_type_MemoryError,
"memory allocation failed, allocating %u bytes", (uint)num_bytes));
Are these equivalent? Looks like you cleaned some of these up, and they haven't been cleaned up in MPy.
I am mostly keeping your changes, which uses shorter forms ("raise_IndexError" vs passing in the exception type, e.g.)
tulip sleet
So mp_ vs nlr_ is not different, jsut a lower level call (?). These are just the merge conflicts.
slender iron
nlr is lower level I think
tulip sleet
That's what it looks like. Most changes are easy. The esp8266 merge was kind of messy, and I may have to go over it. ufoo vs foo modules, etc. Some new stuff added on their side. Otherwise not bad. (Dyno does not like x x x
will keep going. tnx

__MICROPY_INCLUDED_FOOBAR_H__ changed to MICROPY_INCLUDED_FOOBAR_H everywhere in MPy,(dropping __), so I made ours consistent as well.

Does CircuitPython make any assumptions about the size of the SPI flash?
royal ridge
K
royal ridge
#define BOARD_FLASH_SIZE (0x00040000 - 0x2000 - CIRCUITPY_INTERNAL_NVM_SIZE) ??
(from feather m0 express)
tulip sleet
@royal ridge that's the on-microcontroller flash
tulip sleet
it's used in spi_flash.c, and defined elsewhere
royal ridge
(which TOTALLY makes sense)
tulip sleet
right
royal ridge
K, so, it'd be REASONABLY simple to give my feather express a much bigger backpack.....
(no, I'm not actually doing it at the moment.... but I'm thinking about it)
slender iron
Yes @royal ridge

Took a little while to find them: travis and rosie statuses for any push can be found here: https://github.com/adafruit/circuitpython/branches (click on Branches link on main page for adafruit/circuitpython). Click on the X or checkmark. 1.9.2 merge is passing rosie tests on the first try (!).
tulip sleet
Some notes on MicroPython v1.9.2 changes. There are many fixes, and also many stylistic changes. I'll put this in the commit message or a pull request comment as well:
Micro Python -> MicroPython everywhere.
#include guard #define's lose their leading and trailing double underscores
(The above two affect many files and account for the majority of changes in the merge. I've edited our own code to include those stylistic changes going forward.)
nlr_raise_whatever -> mp_raise_whatever (higher level exception raising).
Double precision added, including libm_dbl double precision math library added.
Many tests improved.
For STATIC dicts, mp_map_elem_t replaced by mp_rom_map_elem_t, and the macros defining the entries changed from OBJ_NEW_whatever to MP_ROM_whatever. I'll make a pass over our own code to do this as well.
mp_uint_t -> size_t where appropriate.
.. -> $(TOP) in makefiles.
Some changes and additions to rst documentation markup. See CODECONVENTIONS.md for details. In particular, argument names are asterisk'd, not backquoted. Addition of docs/templates/replace.inc; it includes boilerplate text that can be inserted by inserting a small |something| marker.

It'd be great if I could figure out how to use a NeoPixel ring with Feather M0 Express
The fragmentation is confusing me. I tried reading into the guides, but it seems like Circuit Python varies for each board. It's not used the same way board to board.
timber mango
Kurticus, 90% of difference is pins. After that it's pretty much the same.
I'll get my basic CP Neopixel /animation stuff posted to github this coming week. That'll help.
formal plover
Thanks @timber mango!
import digitalio
from board import *
import time
led = digitalio.DigitalInOut(D10)
led.direction = digitalio.Direction.OUT
while True:
led.value = True
time.sleep(0.1)
led.value = False
time.sleep(0.1)
timber mango
The biggest gotcha is CP is slow for Neopixel still... stuff that blazes on same hardware using Arduino/C is slow with Circuit Python at this point. For 10-20 pixels, it's not bad, but then speed drops too much...
timber mango
That should be correct, I think. I'd have to double check it and can't right now.
Is it working for you?
formal plover
Nope
There's no debugger, so not sure what's wrong . NeoPixel is showing an error with the code
timber mango
Wait, that's a Neopixel or a Led?
Those are totally different animals.
Neopixel is not the same as above at all.
formal plover
LED. but the Neopixel is supposed to be a s,low pulsing green showing everything is good
timber mango
Ah, I see what you mean..... you meant there is an error.
formal plover
Yeah, sorry
timber mango
What does the REPL say?
That's the debugger.
If you connect to usb serial at 115200, you get the debugger and also can access the REPL...
timber mango
Add some debugging prints
Print ("turn off"), etc
You should see that output to the serial while it's running.
If you don't see Turn off, Turn on, repeated over and over, you know the loop isn't working for examplem
formal plover
pin is not defined
timber mango
Ah, what LED, the onboard one?
timber mango
Pin 13 is onboard led, I think.
formal plover
I changed it to Pin D10
formal plover
That worked
However that was the blinky example from the readme
well form there
timber mango
Hahaha, bug report that. It's wrong. @slender iron @tulip sleet
formal plover
Yayyy look at that, I found a bug!
timber mango
The learn guide example of blinky on feather M0 is correct.
(Which is why I caught the out vs output issue)
Gotta run, glad I could help get you blinking.
formal plover
Yeah, that one is for the on board LED. I was messing with my neopixel ring and couldn't figure it out. So I was like okay, I at least want to test on analog and digital read/writes
Yes, thanks for the help!
timber mango
Neopixel are different. But not hard. Just have to understand how they work. I highly recommend TonyDs videos
formal plover
Yeah, I'll check some out. That's how I got started using my M0 with my Chromebook
slender iron
thanks for the bug @formal plover !
formal plover
You're welcome! I found it, but @scruffynerf identified it. 😀

💯
I am starting with the basics; digital & analog read/write, controlling LEDs and servos. Then maybe some OLED displays or 7 segments

we should build out some code katas for circuit python.
solar atlas
Adjusting for pin numbers & pin quantity. Will micro python programs done on Circuit playgraound carry over to the new trinket MO & gemma MO?
solar atlas
Question pertains to the physical Circuit playground too but however, my main thinking is: can a program be written using makecode.adafruit.com or the Microsoft make code app and then transferred to a Trinket MO? Mind you I haven't checked but this question is going on the assumption that you can turn the block code into micro python code.
royal ridge
Makecode decomposes to typescript, IIRC, and there's not currently a typescript core for trhinket/gemma
solar atlas
Thanks @royal ridge . Does that mean that you can't edit the code on the Trinket MO & Gemma MO as easily as u can the circuit python? Cuz that's what I was thinking as to how the block code might be able to be transferable. By just copying the type code once the block is up loaded to the Curcuit Playground.
royal ridge
makecode isn't circuit python. it's a different language.
solar atlas
Ya its the block code isn't it? Or do u mean once it's downloaded to a physical Circuit playground its different and not editable the same way as if you programmed it directly using circuit python?
slender iron
@solar atlas Correct. The code Make Code generates is not CircuitPython compatible.

I have a question about IR for
'''ir_read = pulseio.PulseIn(board.IR_DX, maxlen=100, idle_statuse=True)'''
does that only record at 38KHz? if i wanted to make something harder for others to read how would i go about reading at say 27KHz?
slender iron
PulseIn doesn't do the 38khz demodulation. the IR receiver does

I would like to install CircuitPython on my Feather M0 Adalogger. Is this the best/most up to date tutorial? www.learn.adafruit.com/micropython-for-samd21/overview
tulip sleet
@heavy sluice That's pretty old. Follow the Trinket and M0 Express guides, but use the adalogger version of circuitpython. The Trinket is most up-to-date re CircuitPython, and M0 Express guide will have pin info that's appropriate to Feathers. Notice that you will have much tinier local filesystem (64kB vs 2MB), and if you re-upload CircuitPython, you will wipe out the filesystem, because it's stored in the internal flash of the microcontroller.

Hey @tulip sleet, how much of a headache would it be to get an adalogger board to treat the sd card as our SPI Flash chip?
tulip sleet
@ogredrew See here: https://github.com/adafruit/Adafruit_CircuitPython_SD. Note you need CPy 2.0.0+.
If you want to do imports from the SD card you'll need to add its filesystem to sys.path.
royal ridge
ohh nice.
the Silly Questoin: does it show up as part of the circuitpy drive when connnected to a computer?
remote sandal
@tulip sleet Thanks!
tulip sleet
@royal ridge See the example in the library link above. If you follow the example, it will be mounted as /sd, so it should appear as a top-level folder named "sd". I have not tried this myself.
royal ridge
Hrm... gonna have to decomission my adalogger and find out 😉
tulip sleet
I have a spare one right here. I'll try it.
royal ridge
Dan, I ❤ you forever
tulip sleet
Note that some fetures are missing from the firmware due to lack of space.
royal ridge
I'll have to look at the feature comparison, but I'm really just tthinking about 'whole dev environment in my pocket' right now
(this is how my brain works)
tulip sleet
Also the adalogger doesn't come with the .uf2 bootloader initially, so you'll have to use bossa
royal ridge
There are worse things
is there a uf2 version for the adalogger?
goes hhunting
wait.. the feather boothloader should be universal across the SAMDs....
unless pa06 is in use somewhere else..
tulip sleet
You don't have to replace the bootloader now: do bossac -evwR adafruit-circuitpython-feather_m0_adalogger-2.0.0-beta.1.bin
You'll need a 2.0.0 version of https://github.com/adafruit/Adafruit_CircuitPython_BusDevice/releases. The releases there are for 1.0.0, so you'll need to mpy-cross it with a 2.0.0 mpy-cross.
Also I started trying this, but I only seem to have 16GB uSD cards handy, so not sure they will work.
Is this all just because you don't happen to have an M0 Express yet?, or do you want a big card?
royal ridge
Bigger storage space
solar whale
@upbeat plover If you are using a CPX - try lis3dh=adafruit_lis3dh.LIS3DH_I2C(i2c,address=25)
trying to find the doc, but that is how I have it setup and i works for me.

@slender iron lol
tulip sleet
Dans are great

dusk hemlock
the code is a sample sketch from the Adafruit library, it runs fine on Metro M0 Express but on ESP the watchdog is reseting the chip constantly
dusk hemlock
yeah, other code runs fine, I've flashed CircuitPython, MicroPython and NodeMCU on it
I've even tried running it on several different boards with various flash sizes
slender iron
I can't help much with arduino. If I were debugging it I'd printf a bunch to figure out where it was hanging
dusk hemlock
yeah, no worries, I thought to give CircuitPython a shot if there would be a driver for it
thanks, I'll do that
tulip sleet
@dusk hemlock I did some brief Googling and it seems like you shouldn't put delays in setup() on the ESP8266.
Try moving the demo code into loop() and don't have delays in setup().
E.g.: here people are talking about disabling watchdog in setup(), which you don't need to do because the demo code could all go in loop(): https://github.com/esp8266/Arduino/issues/34

it was @limber tulip who had the issue I think! if not I'm really sorry and I'll stop @ ing people now. but the WDT issues with the feather could be that setup() taking longer than 1s errors out
slender iron
@river quest @tulip sleet and I did our sync up in a voice room and had some other folks participate. It was awesome!
limber tulip
I did/do have problems with the Music Maker Wing throwing exceptions on Huzzahs
Gave up solving it b/c the same Wing works on the M0
This problem is not, however, related to setup time or WDT
WDT was only in play due to the exceptions

I might consider something that won't wear out an SD card for Rosie East. I have a spare little Dell box, NUC-sized. It has a proper SSD. Also seems like one can boot an RPi3 from an HDD if it spins up fast enough: https://www.raspberrypi.org/blog/pi-3-booting-part-i-usb-mass-storage-boot/.

Scott's is a little sad right now, but he is rebuilding it, with a newer Raspbian, I think. Might have been the SD card or some other problem.

@prime flower The last couple of times I did it, it was a really smooth install. You should look into it again if you haven't recently.
tulip sleet
it worked fine for me but the disk I/O is slow. A circuitpython build took several minutes instead of 20 secs. It also needs serial ioctl() support, which is in progress.

slender iron
@formal plover try using linux to flash the esp
@tacit glade I think I see the hang you are talking about
tacit glade
@slender iron, that's good and bad I guess
slender iron
definitely good 😃
tacit glade
good for me because I'm not doing things in some weird way, bad that there's such a big delay
idle owl
@solar atlas I turned it into a tone piano that uses the capacitive touch pads as keys, and lights all the Neopixels for each note. And the slide switch mutes it
@solar atlas I'm also working on a tabletop lightbox photo studio using just under 2m of dotstars, PVC, a small ikea side table, ripstop nylon and various other little bits. Running the dotstars from a Rasberry Pi. Nearly done with that.
formal plover
@slender iron will do
slender iron
@tacit glade looks like the volume isn't being increased
tacit glade
Depends on which scenario you have set
tacit glade
@slender iron do you have the RST pin connected to the Metro?
slender iron
no
tacit glade
have you been getting messages back from the board? I'm trying to figure out if the soundboard is already in UART mode...
tacit glade
yeah, definitely make sure that UG is connected to GND per the guide instructions
https://learn.adafruit.com/adafruit-audio-fx-sound-board/serial-audio-control#general-usage
slender iron
ah ok 😃
tacit glade
then as long as RST is connected to your metro and you specify that pin in the constructor, it will make sure the soundboard is ready to talk over UART
slender iron
ok, I need to grab another wire
tacit glade
feels weird for me to be giving you instructions, haha
idle owl
lol
slender iron
your commit was my guide 😃
tacit glade
good. hopefully it made sense
ah, looks like the project's README doesn't mention anything about the UG pin. I'll correct that now
tacit glade
interesting
slender iron
I'm gonna take a look and see why
the danger of calling read is actually getting fewer than 7 bytes back
tacit glade
right, because then it will hang again, right?
slender iron
maybe. you won't read the full volume number it responds with
tacit glade
@slender iron I know this is kind of an obscure question, but do you know what motivated removing the UART.any() method from the upstream MicroPython?
slender iron
I just never implemented it
and its a terrible API IMO
its simply the buffer length
so readall is slow because internally it tries to read the default buffer size. which is why you get a timeout
tacit glade
is there another way to check the buffer length myself? or should I find some way to read one byte at a time until the buffer is empty?
slender iron
I think ideally you'd know how many characters to expect in response
you can always read(1)
to get a single byte
tacit glade
I see. Well that gives me something to think about. I set things up so that one method does all the communication regardless of the command sent, so that runs a bit contrary to the approach of knowing how many bytes to expect for a specific command, at least the way it's programmed now. Thanks so much for taking a look a things @slender iron
solar atlas
Hay @slender iron . You had that you guys want the board guilds to be the teacher. Does that mean that circuit python is different depending on which board it's on?
slender iron
@tacit glade you can always pass it in when you know it and fall back to read(1) when you don't
@solar atlas nope, we just want to be able to give specific instructions
tacit glade
true. I'll do some experimenting when I can and get back to you. thanks for all your efforts to help debug my code
slender iron
on our end we can share content between guides where its the same
@tacit glade not a problem! I'm happy to help. I'll leave it on my breadboard for now
solar atlas
Ah gotcha @slender iron . Ok so then is it https://learn.adafruit.com/adafruit-trinket-m0-circuitpython-arduino that I shld basically be reading then right?
solar atlas
K thanks. 😃
solar atlas
Lol, dnt suppose that it has one that cld automatically run a string of dotstars?
slender iron
I think its in progress.
looks like the library needs a little love: https://github.com/adafruit/Adafruit_CircuitPython_DotStar
idle owl
I fought with those for so long....
slender iron
@idle owl polishing up the dotstar library based on this guide would be helpful: https://learn.adafruit.com/creating-and-sharing-a-circuitpython-library/releasing-on-github?view=all
climbing time! ttyl
idle owl
@slender iron I ended up going with a different library, and in the end, someone who knows a lot more than me wrote most of the code for my actual file.
Have fun!
slender iron
which library @idle owl ?
idle owl
@slender iron https://github.com/tinue/APA102_Pi
@slender iron We're only using the apa102.py file, and the rest is all custom in another file. I'm also using all white Dotstars, and while they respond to the RGB code, the rainbow and animation stuff isn't quite the same. I also needed some specific features like specifying every other LED for example.
I need to ask my friend who wrote my custom bits whether he cares if I open source it, and if he doesn't mind (which is likely), I'll post everything we did.
timber mango
@idle owl The 'every other' code hopefully is done similar to the neopixel slicing that works in CP.... [and I'm hoping to push code soon (likely in an unoffical repo to start) that all works with CP and makes a lot of it easier to abstract (so eventually neopixel or dotstar, it'll all just work the same once you create the object)
idle owl
@timber mango I'm not sure how the Neopixel slicing works in CP. We did it essentially manually. The entire project is divided up into strips of 9, set into 3 squares of 4 strips each. So specifying every other is a matter of writing out the code to apply to 9 LEDs and then pushing it to all the strips. It was a long day, so we decided we needed code that worked, and elegance would have to wait.
timber mango
the neopixel slicing is using pure pythonic array slicing (so given 10 pixels 0-9, you can use python array slcing like pixels[start : end : step] such as pixels[::2] which would do every other pixel....
the advantage is you can take advantage of all the python array tricks/code....
idle owl
That would have been much easier. Wouldn't have covered a few modes we included with inconsistent numbers and locations of LEDs - inconsistent in the sense that it's not every third or something. It's the second one, then the even ones, which would mean, if done for the whole strip would have been 2, 4, 6, 8, 11, 13, etc. But I'm honestly not sure we needed every one of the modes we included. Once we started doing them, we just did a bunch more.
timber mango
it also allows negative slicing. And I actually have code for arbitrary reuse of pixels (to allow you to literally make a pixel object of '2,4,6,8,11,13' as you wish, and treat it as it's own object (so you could just 'fill' it, etc.
that code is coming soon.
idle owl
Good to know.
We're going to need to improve this code eventually. Like I said, it works. It's not pretty.
timber mango
the goal is taking multple strips, combining them togther and then making new sub'strips' of pixels so you can just use them as you wish.
idle owl
That's kind of exactly what we did except mostly manually
That and physcially. They're all wired in groups.
timber mango
yeah, I wrote it generically, got inspired by TonyD's work on the reactor, and then wanted to do the opposite (turn a circuit playground into 2 half rings.
idle owl
Neato!
timber mango
in parallel, two strips do the same thing.
useful if you want to put 2 strips back to back, or on opposite sides and have them mirror.
idle owl
No they're all serial, so it's just wired into squares out of a 2m strip.
Yeah it would be
slender iron
@timber mango I haven't added the slicing to the dotstar library yet. I've been meaning to though
timber mango
I made sure to support it in the neopixel chaining/ninjaing helper stuff I wrote, it was so simple and neat.
I just started organizing code to share that among other things. made a git repo for it /sethcohn/circuitpython_helpers (nothing there yet, my code is a mess and I wanna clean it up a bunch before I push anything.)
if stuff ends up feeling useful as an adafruit-y helper library, we can spin bits off, but this way, it's just me futzing around still.
mostly it's 3-4 areas of interest... TonyD inspired for some of it. SignalProcessing stuff (makes it easier to do flow-y animations if the signal processing helpers are all in one place), Pixel munging (the above chaining/ninjaing), Animation class (and lots of example animations... I'm enjoying converting c coded into python, or even python into classed python), and Misc Visual helpers (color/gamma/etc)
slender iron
ok, lets get it in the community bundle too when you are ready
timber mango
yeah, once it's in a good shape, we can discuss how to do that.
it's a bunch of things, so for now, having it in one place is good, but really, it's a few different things, and library space is tight enough, few will want or need all of this at once.
slender iron
sounds good. the bundles also nice so I can keep track of it and send pull requests if it needs to be fixed up
sick creek
omg finally I can flash my rpi2 sd card so rosie if it fits to it
tulip sleet
@slender iron core.temperature is working. However... having trouble fitting it into non-Express boards, which is the original idea.
Before 1.9.2 merge, Gemma M0 had 244 bytes free. After merge, 28 bytes free (!). Adding core.temperature overflows by 392 bytes. I also added core.frequency when I was debugging. That's 80 bytes of the 392.
Trying to see what to remove...
Could trim 4k-8k off of filesystem...
or less
tulip sleet
gcc option -finline-limit=<n> limits the size of inlines. -finline-limit=80ish is close to current size. Going to 70 or 60 frees up enough. 20 gives 1132 bytes free.
Interestingly, -fno-inline is way worse. Overflows by 5656, which means that many functions are smaller than function call overhead size.
off to lunch
slender iron
tuning inline-limit sounds good to me @tulip sleet
slender iron
it shocks me whenever ASF4 generates a GCC warning
slender iron
@tulip sleet I'd like to add a knob to facilitate porting CircuitPython. It would basically control what functionality gets compiled in
would it make sense as a value in mpconfigport.mk?
tulip sleet
want to audio chat?
slender iron
sure
sick creek
2.0 is coming
slender iron
@tulip sleet I think you have changes to push to your PR
tulip sleet
@slender iron Not done yet; I should have waited. I just commented on the things so far. Still fixing the doc. nvm is marked as an attribute in shared-bindings/microcontroller, but as a module in shared_bindings/nvm. I might be able to mark things as an object; I see something like that in the sphinx source. Also microcontroller.core is an orphan right now in the sphinx tree. Gotta fix that.
slender iron
the microcontroller.core should be an attribute whose value is an object
nvm is a module with the ByteArray class in it
so microcontroller.Core would be like ByteArray
tulip sleet
So ByteArray and Core are fictitious. There are actually no such classes. That's what you mean, right?
nvm is an object that's duck-typed to look like a bytearray
I'm not sure I see how nvm is a module, because you can subscript it: nvm[0:255]
slender iron
there are two nvms
one you can import thats a module and one thats an attribute on microcontroller
ByteArray and Core aren't ficticous you should be able to get the objects type and get it back. you just can't create one of your own
tulip sleet
ah, ok, I didn't realize you could import the shared-bindings/nvm. I was wondering why it was at the top level. I implemented core as a singleton object with its own unique attributes and no useful class. Ok, I need to write some more dicts, etc. to fulfill that model. I need to make a core at the right level. Sorry for the misunderstanding.
slender iron
yeah, its a bit weird
but for the core stuff there will be microcontroller.core and microcontroller.Core
timber mango
ugh. Capitalization difference?
tulip sleet
>>> import nvm
>>> nvm.
__name__ ByteArray
>>> nvm.ByteArray
<class 'ByteArray'>
>>> dir(nvm.ByteArray)
[]
>>> ba = nvm.ByteArray()
>>> ba
>>> ba[3]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'NoneType' object is not subscriptable
>>> type(ba)
<class 'NoneType'>
@timber mango yeah, we could rename it though
@tulip sleet yeah, it should probably raise an exception or return the singleton like you do
right now it returns None
tulip sleet
yeah, not sure if it should throw or return microcontroller.nvm. There's no standard way of doing singletons in Python I can find.
tulip sleet
I agree. I'll see about having it throw and saying to access via microcontroller.nvm instead.
slender iron
thanks!
tulip sleet
@slender iron I had to force-push after the rebase, and that made some source changes not visible in the original pull request. I closed that and opened a new one.
core is a proper module now with a core.Core class. Also redid module support matrix: transposed it to make it not so wide and added core and nvm modules. But could back that out if you don't like the way it looks.
24 bytes left in non-Express builds. Could decrease -finline_limit if we need to add more.
aaah - forgot to check sphinx build. well, we'll see
timber mango
just successfully flashed Wio Link ESP8266 to micropython 1.9.2
And now I've successfully flashed CP 2.0.0 beta 1 onto the same board.
timber mango
and I got the wireless webrepl (and mpfshell/fuse too) working. Nice job, @slender iron / @tulip sleet I know it's not a 'supported board', but the huzzah binary firmware for CP seems to work so far on the Wio Link.
hushed plover
i just have a simple ESP8266-01.. no fancy breakout boards or anything..is that supported by circuitpython?
timber mango
@hushed plover the ESP -01 only has 1 mb of flash, so I'd bet circuitpython might not work (it might... it's only 600k or so), but I suspect one of the Micropython firmware will certainly work: http://micropython.org/download
hushed plover
ive already got micropython and i love it - i was curious if circuitpython had more useful features for actual circuit creation
hence why i came to ask 😄
timber mango
ah... no, functionally it's similar... adafruit is doing a lot of work to enhance improve MP... lots of small things.
hushed plover
mostly trying to hunt down a way to use mongodb...
timber mango
???
hushed plover
pymongo for micropython :/
i cant seem to find anything about it, so i was looking around to see if it would be potentially easier to make my own restful api for mongodb with circuitpython
timber mango
yeah, the wifi/network stuff isn't something improved (yet)
few of the adafruit boards have networking at this point...
did you see this?
that's not python though.
hushed plover
yeaaaaa i only really know python
(though js isnt that confusing..)
i could just make a server/client sort of thing
where server has a socket waiting for commands and then sends them off to mongo
timber mango
so have you tried pymongo on micropython?

hushed plover
it doenst install
if theres no micropython-* in upip, it wont install
you cant juse upip.install('pymongo') - the board crashes
timber mango
I'd go ask in MP forum, and see if anyone is interesting in helping you figure out the missing bits.
timber mango
OR, as you said, write just enough to make it work for your needs.
hushed plover
basically the project is making a sort of portable little wardriving box
since i can scan for wifi with the esp i can return a list of all the networks found
i thought a database would be interesting for logging, but the main idea was to display them in a web interface
timber mango
I've seen that done on esp without python...
solid idea.
wait, you wanna put mongo onto the esp?
or figure you'll store data on db afterward?
cause you won't be able to push data to mongo while scanning.
hushed plover
i could if i were able to talk to a GSM network
timber mango
oh, that's different, using some other network besides wifi.

an utterly fantastic little list
timber mango
ah, I found it for you: https://github.com/nakagami/nmongo
hushed plover
!! 😮
timber mango
I win.
timber mango
btw, google search that hit this first: micropython push to mongodb
yeah, that's just adding spi flash, I think.
hushed plover
you literally take the existing flash off
the board is so tiny i couldnt do it myself..
timber mango
given the price of new boards, buy a 4meg board. 😃
timber mango
yup, tiny tiny stuff.
hushed plover
i love it, thats why i want to use the teeny esp
timber mango
I mentioned it above a bit... I have mpfshell doing fuse mounting (again, the author stopped doing it, removed his code)
so that I literally have my esp8266 remotely mounted into a directory via wifi...
it can be plugged power across the room, and I can edit files using my laptop editor.
hushed plover
thats super neat

but then it needs to compile it into bytecode, and that could be running out of space.
hushed plover
timber mango
pre-compile into nmongo.mpy then put that onto board.
hushed plover
perfect
timber mango
they did change mpy format at some point (unsure when...) so make sure you use same version of MP code as you have installed
(for CP, v1 doesn't work with v2...)
timber mango
just grab the source for whatever version, and compile the mpy-cross there.
hushed plover

ah.

(not that theres many files 🙄 )
timber mango
yes, you can, and should if space is tight.
timber mango
you should do that for all of the files in /lib

good luck. Let me know how it goes. I'm gonna play with nmongo at some point now... too nifty to not.
hushed plover
heres how ive been using pymongo
db_user = 'user'
db_password = 'password'
from pymongo import MongoClient
client = MongoClient()
#our db
db = client.dbname
#lets auth that
db.authenticate(db_user,db_password)
#our collection
codes = db.collection
codes.insert({'discordId':this_id, 'FC':this_info})
as an example my discord bot stores nintendo switch friend codes in a mongo database and recalls them by using @username
so that function looks a bit like
if codes.find_one({"discordId" : user.id}):
cur = codes.find({"discordId":user.id},{"_id":0,"FC":1 })
for doc in cur:
qResult = doc.values()
ourFC = list(qResult)[0]
return await bot.say('Their FC is '+str(ourFC))```for the record, mongodb doesnt require the auth by default, but i set it up earlier
if thats something you want i used this
but instead of modifying /etc/mongodb.conf i changed the systemd flag
[Service]
User=mongodb
ExecStart=/usr/bin/mongod --auth --quiet --config /etc/mongodb.conf
just add --auth
timber mango
so you gonna add a gps element to this, so it'll map it all out?
hushed plover
im not sure
i once used kali linux and my android phone as a gps transmitter to map wifi points on google maps with kismet
timber mango
walk/drive around with the tinyest wardriver ever...
hushed plover
but that was with an app, bluenmea, my phone acting as a hotspot, and some dirty socat commands
timber mango
little button on your lapel.
hushed plover
i dont know if theres micropython code for gps, buit that would be fantastic
also you can apparently add an external antenna to the esp by soldering PWR to the weird..wobbly antenna thing on the esp and the other side to GND
timber mango
hushed plover
i think a restful api would end up being more esp friendly than a full mongo library, but who knows
timber mango
uses Adafruit Ulitmate GPS breakout
You can always trim nmongo.py down to just the bits you need.
hushed plover
thing is, if im going to use gps why dont i just go for full blown gsm
slender iron
@tulip sleet what was the rebase trouble you were having?
tulip sleet
@slender iron if you go to the old pull request I closed, click on "View Changes", and you'll see the problem. https://github.com/adafruit/circuitpython/pull/210
View Changes link is: https://github.com/adafruit/circuitpython/pull/210/files/adc2ddb51429c64548d4180cdc55837fbba3b4c7
slender iron
yeah, that makes sense because the comments were on a commit that got force pushed
the Files Changed link at the top works still though
tulip sleet
Oh, that's not so bad. Ok, next time! Actually I'll be more careful to rebase immediately instead of merge. When I wanted to rebase I saw the hundreds of commits from the merge, and if I tried reordering I got merge conflicts. It pays to pull early and often and rebase before too many changes have happened.
Of the changes you requested, the only one unfulfilled in the old pull request was to reimplement as Core.core, so that's in the new one.
slender iron
kk, I'll take a look now
tulip sleet
... I was just looking at adding ".frozen" to sys.path. I'll have to do it in main.c for both atmel-samd/ and esp8266/. The ".frozen" change is a general change for all ports in py/, but there's no general call to set up sys.path in each port. Probably should fix that eventually.
slender iron
yup yup, unifying main.c will allow that
formal plover
Wednesdays are my geek out days, so I'll be hopefully tinkering with my Feather M0 Express and the Feather HUZZAH ESP8266.
slender iron
awesome @formal plover let me know how it goes
formal plover
Thanks @slender iron! I'll definitely do that. I'll be taking a break during ask an engineer of course. Lol
I don't have a project yet. My goal right now is "how many sensors, NeoPixels, servos, misc components can I get to work with Circuit Python.
Not counting the on board stuff, that's pretty well covered.
slender iron
@tulip sleet I don't think core needs a separate module
timber mango
yeah, now that I have a WIo link (ESP8266) running CP, I'll tackle making sure all of the grove sensors I have have drivers for CP too. @formal plover thanks for reminding me.
slender iron
maybe we could have the attribute called core and the class called Processor
timber mango
I like Processor, makes sense with temperature, etc.
formal plover
You're welcome @timber mango!
manic glacierBOT
I built the docs with sphinx locally to check, and it looks OK. I forgot the ending ========== line the first time, and pushed a new commit to fix that.
tulip sleet
@slender iron so rename Core to Processor, and make microcontroller.core be the singleton instance of that? Or call it microcontroller.processor? What would you say distinguishes the stuff in microcontroller.core from the plain old functions in module microcontroller? I think a bit of part of the problem is that microcontroller is a module with functionlity, but it's not a class.
slender iron
ah good point
I'd be ok moving that functionality into the Processor class
then interrupts_enabled could be a property
thats more work but does unify things I think
tulip sleet
And the only other function is delay_us(). There could be other functionality like reset, brownout detection, etc. I could move it. Not sure anyone is using the interrupts code right now in any library. I'll look later.
slender iron
yeah, delay_us is a bit weird
tulip sleet
I kind of like microcontroller.processor better than microcontroller.core
delay_us() should be in a time-like module.
slender iron
ok, I was just hoping to name the class differently from the attribute
yeah, I was debating having precisetime
tulip sleet
I think that would be great. Also some stuff returning ticks as ints rather than floats, maybe, for more precise timing on chips without floating point.
Maybe the top-level module should not be called microcontroller, but something else. Not sure what else.
Kibitzing from the rest of you welcome. Names are hard.
slender iron
yeah, names are hard. I was so blocked on the SD card stuff until I came up with storage
slender iron
machine is a much larger collection with the goal of modeling all of the hardware of the micro
tulip sleet
A board has pins (which are mapped to the microccontroller pins, which are otherwise inaccessible).
slender iron
most of our hardware API is functionally specified rather than structural
timber mango
trying to picture the hierarchy (even if it's not direct, it at least should make sense)
tulip sleet
If we eventually run on some ARM7 without its own RAM and flash, it's not really a microcontroller.
slender iron
we can change it when we do 😃
we'll need to deal with multicore before then probably too
tulip sleet
I think maybe you picked microcontroller because machine and board were already taken.
slender iron
yeah, I do consider that
I'd say do the minimal thing now for 2.0 and we can add precisetime in 3.0
tulip sleet
suppose processor were the top-level module name, and it had a class processor.Processor, and an attribute processor or core ... no I'm not sure I like processor.processor
slender iron
haha, yeah. thats the challenge
I like that microcontroller encompasses the pins too
tulip sleet
OK, I will stick with renaming Core to Processor, and make microcontroller.core be the instance of processor for now. If it's easy I will move the interrupt stuff to Processor. We can think harder for 3.0. 2.0 is too imminent.
slender iron
Sounds good! Thats the nice thing about doing major revs, we can change API where we think its needed.
tulip sleet
Brainstorm while I was cleaning up after lunch: microcontroller.cpu is the instance of Processor. Then cpu.frequency, cpu.temperature, etc. Also it's separated from nvm, which is not the cpu.
tulip sleet
our cat was really interested in the sardines I was eating and i had to share
slender iron
😃
hushed plover
for the record, boot.mpy does not work
slender iron
yeah, I think the filename is hardcoded
timber mango
good to know.
vague monolith
Is there any documentation on the circuitpython dotstar library?
tulip sleet
@vague monolith Did you look at the source? It's very similar to the NeoPixel library, except you need to supply two pins instead of one. Source: https://github.com/adafruit/Adafruit_CircuitPython_DotStar/blob/1.0.0/dotstar.py
@slender iron I looked into doing cpu.interrupts_enabled as an attribute of cpu. But I think I will back off for now. Right now calling disable_interrupts() twice in a row may actually break things, because it remembers the interrupt state and will overwrite it. It should probably remember it was called. On the pyboard, you get an opaque value you have to pass back to enable_interrupts(). Also, one might want to disable/enable only certain interrupts. Kinda think it deserves more thought before we change it and then may have to change it again.
slender iron
sounds good @tulip sleet
tulip sleet
maybe use a context manager to implement critical sections
slender iron
yup yup
formal plover
@slender iron my ESP8266 Feather HUZZAH definitely was never broken... It's broadcasting. Lol I'm such an idiot. I was like, oh no LEDs, busted
slender iron
😃
tulip sleet
@slender iron renamed stuff is pushed and passed. I think you probably got an email. I'm cooking.
tulip sleet
processor is a module. Processor is a class. I was using the same structure as nvm and ByteArray.
slender iron
I don't think we need that in this case because all ports should have Processor
I was thinking it'd be in microcontroller
tulip sleet
so there's no processor/ directory, but processor.c and Processor.c will be inside microcontroller/ ?
slender iron
right, there is no processor.c and all of the Processor.c files will be in microcontroller/. I made nvm a new module to indicate that some ports won't support it. This should be available in all so I think folding it into microcontroller is best.
tulip sleet
But the classname Processor will be visible, right? No anonymous classname. I will try that.
slender iron
right, thats ok
if people use it they'll just get an error suggesting they use microcontroller.cpu
tulip sleet
I guess it's like Pins
slender iron
yup yup
tulip sleet
ok - that makes sense. I'll be back in a while. About to assemble a casserole.
slender iron
k no worries 😃
manic glacierBOT
tulip sleet
@slender iron I did have processor in the Support Matrix indicating it was only partially supported on ESP8266 (no meaningful temperature value)
slender iron
yeah, I think returning NaN or None is enough
tulip sleet
It's documented. OK. ttyl
slender iron
👍
formal plover
Do you think there would be any advantages of Circuit Python running on the HUZZAH 8266 vs using NodeMCU?
vague monolith
Will a feather huzzah flashed with circuitpython show up as a storage device like the Circuit Playground Express does?
Or is that a feature of the serial converter on the express?
slender iron
@vague monolith no it won't it requires USB built-in support
formal plover
Do I have to be using Linux to get esptool to work?!
I'm riding the struggle bus here
I can't get pip to work using pypi
slender iron
I use it on mac
formal plover
This is a cluster on windows
My Linux distro won't display on my smart TV for some reason. I can only get it to work on windows, so that's why I'm trying to make it work.
formal plover
Apparently either Adafruit or someone developed a gui based NodeMCU tool for windows that I can use to flash micropython
slender iron
andrew from show and tell did some flasher for it
formal plover
Nice
slender iron
I can't remember which flasher though
vague monolith
Wouldn't esptool work in windows just have to specify the proper port.
formal plover
vague monolith
There ya go
formal plover
Windows creator update is getting updated right now... 😫
So I'll try flashing Circuit Python on my 8266 after it updates, watching the live show right now anyways
timber mango
@Kurticus I do it on a Mac... msg me later.
More for replacing the usb piece with something similar.
formal plover
Okay @timber mango will do.
idle owl
Oh @formal plover You might not get back to Windows for a while.
formal plover
@idle owl Well it broke my grub menu.... can't get any OS to load right now
idle owl
Oi, didn't think it could do that.
formal plover
apparently it can
hushed plover
i use esptool and it works fine, but ive got the esp8266-01
tulip sleet
@formal plover yes, it overwrites that. You can Google about restoring grub, but it's kind of painful. I use two drives for dual-boot system.
formal plover
@tulip sleet So much pain
hushed plover
i just had the pleasure of sitting on this bus and talking to some older gentleman about fortran and cobol and a whole bunch of stuff id never even heard of
just thought id share that
slender iron
😃
idle owl
@hushed plover That's delightful
hushed plover
It definitely was a learning experience.. I'd never heard of ADT and spaghetti code..
tulip sleet
I am such an older gentleman.
formal plover
well since I pretty much temporarily bricked my PC... figured what the heck I'm try flashing my ESP8266 with my Raspbery Pi
Raspberry Pi* yeah... Don't lol
idle owl
Oh no..
idle owl
I assembled some things wrong, had to take them apart to redo it... Not nearly so bad. At least I realised it before I soldered more wires together, I guess.
And... I just reassembled it the wrong way again.
formal plover
alright @tulip sleet or @slender iron Got esptool on my OTHER pi lol, how do I flash Circuit Python now
tulip sleet
hold on, I have it in my bash history...
formal plover
I can only find the (similar assuming) instructions for micro python
Thanks @tulip sleet
tulip sleet
esptool.py write_flash 0 ~/CP/circuitpython/esp8266/build/firmware-combined.bin
tulip sleet
I didn't. The instructions I found were really long giving lots of options, but you only really need the 0, which says where to start. Maybe specifying a baud rate would make it faster, I dunno. But that works fine.
tulip sleet
I'm doing it on Linux.
formal plover
ditto
i@raspberrypi:~ $ esptool.py write_flash 0 ~/CP/circuitpython/esp8266/build/firmware-combined.bin
usage: esptool write_flash [-h] [--flash_freq {keep,40m,26m,20m,80m}]

tulip sleet
That's my path to the .bin file. Substitute your own.
formal plover
derp
tulip sleet
Once it's loaded, try:
screen /dev/ttyUSB0 115200
to get into the repl. I have an alias for that, I type it so much.
alias huzzah-repl='screen /dev/ttyUSB0 115200'
hushed plover
uhj
hold on
esptool.py --port /dev/ttyUSB0 --baud 460800 write_flash --flash_size=detect -fm dio 0 firmware.bin
this is what the official micropython docs say on how to install the firmware
and its how i do it and it never fails me
tulip sleet
I am using esptool.py v1.2, which takes different arguments. @formal plover, if you type esptool.py -h, what version does it report?
OK!!
Well, maybe the same arguments. The help info is not consistent. @hushed plover's method may be faster or more reliable.
formal plover
Blue LED is flashing really really fast
tulip sleet
But it's giving you an increasing percentage on the command line, right? It takes tens of seconds.
tulip sleet
sudo apt-get install screen
tulip sleet
To exit from screen, type ctrl-A at the beginning of a line then backslash, then answer "y" to "kill all windows" or whatever. You can't just ctrl-C out of screen.
formal plover
It won't stop lol
The second I reset blue LED goes cray
I'm using the beta CP
I guess switch to stable
tulip sleet
Rpi might be screen /dev/ttyAMA0 115200
formal plover
okay, now just a blank line
tulip sleet
oh, I think that's for something else, sorry
formal plover
I thought the baud rate was supposed to be different
tulip sleet
Try 9600, but 115200 works for me.
solar whale
screen /dev/ttyACM0 115200
tulip sleet
@solar whale Thanks, Jerry! Jerry knows -- he does dev on Rpi's all the time.
solar whale
@formal plover glad to help. Good luck!
formal plover
no such file or directory
solar whale
Hmmm.
formal plover
I think there's a problem though
The blue activity LED pulses like crazy
no matter which rev of CP I flash
solar whale
Sorry if this is esp8266 then use /dev/USB0
/dev/ttyUSB0
formal plover
I got a weird page
hushed plover
ls /dev | grep ttyUSB*
formal plover
spitting out bad characters again
[screen is terminating]
pi@raspberrypi:~ $ screen /dev/ttyUSB0 115200
solar whale
Gibberish at reset is normal. Should stop .
formal plover
Lasts endlessly
Now it just terminates the screen every time I try to connect
pi@raspberrypi:~ $ screen /dev/ttyUSB0 115200
[screen is terminating]
pi@raspberrypi:~ $
solar whale
Disconnect USB then reconnect and type dmsg
Last entry will show the USB connection.
hushed plover
id personally use minicom...
solar whale
Ok - old instructions had wrong size. You an also try erasing flash before loading...
formal plover
How do I erase?
hushed plover
esptool.py --port blah erase_flash
solar whale
Yup
formal plover
lol wait, what?
formal plover
Device is busy
solar whale
Is screen connected? If so exit
solar whale
Depends. Proper exit is control -a then \ and answer yes
formal plover
Just unplugged the &#@( thing lol
It's been wiped
That was it the whole time!!!
lol
Needed to be wiped
solar whale
Cool!
formal plover
Thanks @solar whale
solar whale
Have fun!
formal plover
I have a blank line for screen now though
nvm press any key for REPL
we're live!!!!!!
yahooooo
autumn umbra
solar whale
Good idea to erase whenever you load a new image.
@formal plover one other tip. When you start using ampy to load scripts, you must exit screen first. Only only one program can access the USB port at a time.
formal plover
Thanks for the tips and help @solar whale!
