The argument approach is an excellent solution.
Leaves it open if the chip shortage mandates yet another backlight controller chip, as well.
I created an empty repo with all the pre-commit scripts rather than cluttering the project repo with files that need to be kept up-to-date.. I’ve been using the empty repo as an environment for local testing. Yeah, I know it’s an extra step or two, but having only one pre-commit config to maintain fits my occasional use workflow.
Exactly.

50,000 Hz
Is that part of the “adding C code modules to CircuitPython core” functionality? If so, I’ll bet a bunch of folks would be interested in such a guide.
You’ll get a lot of questions about using interrupts. 😏
Just the 3.5-inch FeatherWing and 3.5-inch breakout board
Hmm. And the 3.5-inch piTFT.
The FeatherWing driver doesn’t dedicate a pin for backlight control. Don’t know about the piTFT; checking…
… piTFT has a separate backlight pin, as well. Learning guides talk about 1000Hz and 5000Hz pwm frequencies, so they’ll need updating when the FeatherWing and breakout guides are updated.

Can you even do interrupts with CP? I heard only MP can use interrupts.

I see. There's no way to write callbacks or enable interrupts in CP.

I mean the Plus any modules on the filesystem part. How would you put a module on the filesystem?
Hmm, I was hoping to load a C-language module that isn't baked-in.
you can set the config option core. pager to cat

I guess you wouldn't want to write an interrupt routine in Python anyway due to speed.

I just learned this recently myself. Underscore prefix doesn't put it in the module dictionary, so it can't be imported by other code
drowsy inlet
Right, it says it is hidden, which is consistent with what RichSad mentioned re: convention of using _. But for it to not use any memory during execution, it would have to literally replace the expression, I would think.
So perhaps the no-_ scenario instantiates a singleton that is referenced where needed?
cinder wind
So perhaps the no-`_` scenario instantiates a singleton that is referenced where...
Yeah good question. Everything I know I got from https://docs.micropython.org/en/latest/reference/constrained.html#execution-phase and doing some quicky gc.mem_free() tests

Yeah because constants are basically variables that can't be written to. But the overhead of representing them is the same. Typically the "word" size for integers (of const of an integer)

drowsy inlet

right, monospace font, like single backticks in markdown
brazen grove
single backticks are for links and some plugin stuff
upper sandal
make html
I never remember that command
brazen grove
yes, just type "make"
in sphinx make by itself shows you help, normally it runs the default action
sphnx defines the default action to be help
upper sandal
*Circuitpython
brazen grove
no, that's sphinx's makefile
note how help doesn't show you the submodules sync command
because it was added there, but wasn't added to help
upper sandal
❯ make
Please use `make <target>' where <target> is one of
fetch-submodules to fetch dependencies from submodules, run this right after you clone the repo
html to make standalone HTML files
dirhtml to make HTML files named index.html in directories
Title puzzles are uber fun.
dim wigeon
I have some clever awk code I recycle in my own Makefiles that generates the help automatically from the rest of the Makefile. But not everyone uses that.
brazen grove
oh,nice, someone added it

instant pwd html server
dim wigeon
I use Makefiles for my fiction writing too - write in Markdown and/or LaTeX and have Makefiles to build the PDF, ebooks, etc.
brazen grove
I used to use makefiles in place of a source management program -- I had a command that would targzip the current source into a file with a date in the name
before there was github
by the way, the other makefiles in circuitpython run "all" by default, and you can run more than one actions at a time, so you can do make BOARD=... clean all to do clean then build
it's not "clean all", it's "clean" and then "all"
cleaning after all makes no sense
dim wigeon
make BOARD=. . . clean all is equivalent to make BOARD=. . . clean ; make BOARD= . . . all

How to publish html docs on intranet? (Assume SharePoint or Microsoft shop)

@uneven gull The cleanest way I’ve found, unfortunately, is to convert them to PDF. 😦

@upper sandal They do tend to do that, yes.
brazen grove
I think that for a group you should just call contains on all children and return an OR of it
rapid hornet
I figured foamyguy was streaming after he replied so fast
group should just call contains of its children
brazen grove
you can short-circuit the OR, stop iterating as soon as any child returns True
rapid hornet
totally
a group is more of a coordinate space to me
I don't think of a group having bounds. it just contains children
tracking bounds could be a good optimization
upper sandal
I like calling contain() on the children, that way a group can be a "sprite" with a complex shape maybe ?
or is it supposed to be a rectangle ?
rapid hornet
group isn't meant to have a shape. its more to move things together
upper sandal
but what does "contain" mean then ?
rapid hornet
contain in the computer programming sense, not visual in my mind
literally grouping things
upper sandal
ok, but what does it mean practically then ? what is the use case to contain(x,y) on a group ?
rapid hornet
ya, true. It could return a child instead of true/false
more for "what am I pressing at this point on the screen?"
I planted the seed of an idea 🙂
dim wigeon
you can short-circuit the OR, stop iterating as soon as any child returns True
I think if any([obj, obj, . . .]) short circuits too.
And in CPython at least, I think any() takes an iterator.
brazen grove
I think `if any([obj, obj, . . .])` short circuits too.
not if you use the list, you would need an iterator generator instead
dim wigeon
not if you use the list, you would need an iterator generator instead
Ah, good point. I stand corrected.
brazen grove
something like any(x.contains(x, y) for x in group.children)
dim wigeon
Generators still are hard for me to reason about in my head.
I think I need to build a few to solidify my mental model of them.
brazen grove
they are just a for loop rotated by pi/2 into the imaginary domain ;-)
the equivalent code would be:

self.x, self.y, self.group = x, y, group
self.counter = 0
def __iter__(self):
return self
def next(self):

Is there any documentation that describes how bindings are implemented in CircuitPython?
rapid hornet
what do you mean by bindings?
wheat terrace
They way Python communicates with C. Basically, how these modules like Displayio are implemented (shared-bindings & shared-modules folders in the repo).
yeah, correct
rapid hornet
this is a bit dated: https://docs.circuitpython.org/en/latest/docs/common_hal.html

Tnx Tim. Good night to all. Have a nice weekend.
brazen quail
Keep it real...
rapid hornet
python objects are C structs under the hood
I'm happy to answer specific questions too
the makefile stuff is outdated there I think
both links are outdated
rapid hornet
#circuitpython-dev is the place to ask about internals too
I still copy one module to start another 🙂
it'd be great to update both pages
inner spade
Thanks for the stream!

Thank you!!

If you need someone to read it over once you do some updates let me know. I'm still (relatively) new to learning it all

What would be the best board to get that wroks with no code and wippersnapper?

What would be the best board to get that wroks with no code and wippersnapper?
I'm not sure if there is a "best" but something like the QtPy ESP32S2 (or S3) are small and cheaper if you don't need a lot of pins. They also have STEMMA QT hookups so no soldering required.
Something like the Funhouse of Feather ESP32S2 (TFT or nor) give more options for future use too. The MagtTag as well.
lime sierra
i got the esp v2
would that work as well
Adafruit ESP32 Feather V2 - 8MB Flash + 2 MB PSRAM - STEMMA QT
i think its supported as well no?
nova totem
i think its supported as well no?
I think it is. I haven't tried it myself though.

Good morning

This looks like the only ESP32-S2 product without PSRAM https://www.adafruit.com/product/4919
halcyon linden
I would have been here for the start but I was soldering on pins on some items that I received from Adafruit yesterday in my order.
inner spade
No, that one has PSRAM, I believe.
The PyBadge was the most audio noise -prone of all I tested. The PyGamer had the lowest bleedthrough.
Oops, PyGamer performed the best. (Lowest noise)
No backlight on the macropad
It’s OLED, so each pixel has brightness
The OLED controller on the display does the PWM for you based on an SPI register value
halcyon linden
Thanks Tim
inner spade
Thanks for the follow through on the brightness issue!
halcyon linden
Nice seeing more of your processing method

For sure. Thanks for hanging out, hope everyone has a great weekend! 👋

Evening!

Question for Ladyada: if the only available parts for popular boards ended up being BGA, would you figure out how to respin the boards to use them?

Trains are super interesting

Question for Lady Ada tonight: Is there a CircuitPython planned for the new Feather ESP32-S3 board? It isn't in the downloads yet.
I love trains

This would save so much frustration trying to find the right adapter
Ohhh old laptop adapter
I see a lot of potential with those pots
Are you going to carry clear knobs too?
0.4mm QFN are miserable
But RP2040 helped me get better

With the clear rotary encoder could a light sensor be underneath and with code timing act as a switch (cover up ) When this led is off
ionic garnet
Nice. It says on the product page for the Feather ESP32-S3 so I figured it was coming. Thanks
lilac tusk
I’m braving 0.4mm BGA for the nRF52811
Honestly waiting for AdaChips custom silicon from Adafruit
I’d buy as many as I could
Adafruit open source + Adafruit quality documentation = huge opportunity for the open source community
Bye 👋

my initial idea for this was to just capture images when there's a certain amount of ambient light and then send a notification, but the tilt sensor is a MUCH better approach
