can we get more simultaneous builds on azure, or are you hoping to split across travis and azure?
slender iron
yup 10 concurrent
and can do multiple jobs which allows for splitting commands more easily

What is the best way to expand the GPI O on a py portal
I2c?
Good morning everyone!
manic glacierBOT
main meteor
There are handy I2C expander chips like https://www.adafruit.com/product/593 (8 ports) and https://www.adafruit.com/product/732 (16).
crimson ferry
@modest atlas Seesaw is another option for more extensive expansion (7 GPIO, but lots of other goodies) https://www.adafruit.com/product/3657
umbral dagger
@tulip sleet The BLE echo example works fine.
@modest atlas @main meteor Seesaw is fine, but as mentioned has other things which may or may not be useful. It is on a nice breakout, though. The 23017 will give you 16 digital I/O lines but there isn't a breakout afaik. It's usually my goto expansion ship, especially in a custom build.
@modest atlas @main meteor I designed and did a custom board for a 32-bit I/O UNO format shield using the SOIC version of the 23017. My smarthome node uses one for configuration jumpers and a digital expansion port (for things like switches, relays, etc).
tulip sleet
@umbral dagger the error you're showing with BLE UART might be due to not being connected. Is your code very different from the BLE echo example?
umbral dagger
@tulip sleet ```
from adafruit_logging import LoggingHandler
from adafruit_ble.uart import UARTServer
class BLEHandler(LoggingHandler):
"""Send logging output to the BLE uart port."""
def __init__(self):
"""Create an instance.
:param uart: the busio.UART instance to which to write messages
"""
self._advertising_now = False
self._uart = UARTServer()
self._uart.start_advertising()
def format(self, level, msg):
"""Generate a string to log.
:param level: The level at which to log
:param msg: The core message
"""
return super().format(level, msg) + '\r\n'
def emit(self, level, msg):
"""Generate the message and write it to the UART.
:param level: The level at which to log
:param msg: The core message
"""
print('connecting')
while not self._uart.connected:
pass
print('connected')
data = bytes(self.format(level, msg), 'utf-8')
print(type(data))
self._uart.write(data)
@tulip sleet It's all looking fine up until the write. data is bytes just like the result of read in the echo example.
tulip sleet
@umbral dagger could you replace the triple single quotes with triple backquotes?
how long is the string you're trying to write?
umbral dagger
@tulip sleet my bad
tulip sleet
@slender iron I'm seeing BLE problems with latest master (these are not the same problems as @umbral dagger is seeing above)
slender iron
@tulip sleet I'd still publish beta 6
because more people are hitting the usb issue than are using ble
tulip sleet
BLE is completely unusable; I'm bisecting. I think if you revert the nrf RTC PR it will work; just confirming
tulip sleet
i have to leave in 10 mins for the rest of the evening
tulip sleet
Or I can do it tomw. If you revert that PR, build a feather 52840 build, load it, and try this:

File "adafruit_ble/uart.py", line 34, in <module>
File "adafruit_ble/uart.py", line 56, in UARTServer
OSError: Failed to change softdevice state
it should NOT get that error
it is definitely that PR
according to bisect
or, let's revert, wait for the builds, and I'll retest tomorrow and publish beta.6 tomorrow
depends on your schedule now as well

Look at @adabot 
getting in on the discord action! She's so awesome.
umbral dagger
@tulip sleet This sort of works: ``` data = bytes(self.format(level, msg), 'utf-8')
for i in range(len(data)):
self._uart.write(data[i:i+1])
It eventually fails with: ```Traceback (most recent call last):
File "<stdin>", line 1, in <module>

@umbral dagger this is indeed a bug in UARTServer. It should buffer the write. Only 20 bytes can be written at a time, and we need to wait for an ack to come back before writing more. https://github.com/adafruit/Adafruit_CircuitPython_BLE/issues/10

stuck elbow
@slender iron I don't suppose we want displayio to support 4bpp displays?
slender iron
@stuck elbow my goal is to support all the way down to 1bpp. Not by 4.0.0 obviously though
stuck elbow
oh wow
because I just got an SSD1327 breakout to work, and it's a pretty nice 128x128 16-grays OLED display
would be nice for gameboy-like games
and since it's 4bpp instead of 16bpp, it's going to be 4x faster :D
(admittedly, 160x144 would have been even nicer, but you can't have everything)
gilded cradle
@slender iron, do you know if we're planning on eventually supporting I2C displays too?
stuck elbow
I think it shouldn't be hard, there already are two different protocols, adding a third one wouldn't be that hard
gilded cradle
Yeah, that's what I figured.
stuck elbow
especially since the displays use the same command set both for spi and i2c
gilded cradle
Good point
stuck elbow
with just some hack for distinguishing data and command bytes
(usually they add a first byte in front that tells if it's a data, a command followed by data, or all commands)
gilded cradle
Most likely it would target CP 4.X
stuck elbow
I think CP4.0 is pretty much in a feature freeze by now
gilded cradle
Yeah, that's what I meant
I got a couple display related items in there that will allow me to support a bunch of the displays, but I think we're really close now.
stuck elbow
I really can't wait for the badge wing and for displayio doing dirty rects -- then I can write some proper games
gilded cradle
What do you mean by dirty rects?
stuck elbow
I think right now it's pretty much updating the whole screen every time
stuck elbow
but it has those "dirty" flags on the objects
so it could only update parts of the screen, and be much faster
gilded cradle
Yeah, that would make certain slow screens much more responsive.
stuck elbow
I'm doing that with my µGame thingy, and it's enough to have 12fps on 128x128 screen
stuck elbow
it's an older project for games with real graphics
gilded cradle
Ah, ok
stuck elbow
gilded cradle
Nice
stuck elbow
I basically wrote something similar to displayio back then, but more limited
only 16x16 sprites and tiles, 16-color palettes, etc.
gilded cradle
Yeah, it would be nice to add some way to hook displayio drawing functions to hardware accelerated functions if available, but I imagine that being a ways down the road.
stuck elbow
those cheap displays don't have much in the way of hardware acceleration
some have scrolling
stuck elbow
that is way out of my budget
gilded cradle
Yeah, but it would be nice to have displayio working on it.
stuck elbow
what I would love is a display that would have nice big pixels (say, 128x128 with 3" diagonal), 4-bit pixels with a 16-color palette, hardware scrolling horizontally and vertically, and fast SPI interface — that would practically be total bliss
the biggest physical pixels I could find is the 1.8" 160x128 ST7735
gilded cradle
If you find something like that, let Adafruit know.
stuck elbow
by the way, I found something awesome just now
transparent OLED displays
the frame spoils it a little bit, since you can't make a LED cube out of them this way
but you can still make HUDs or stack a few and have some depth
gilded cradle
Perhaps you could remove the frame and glue them together?
stuck elbow
I suspect that frame has a purpose
gilded cradle
Probably to prevent it from falling apart, but perhaps as a conductor/shield?
But they are a bit on the spendy side.
gilded cradle
Yeah
stuck elbow
but maybe in a few years if they get more popular
there will be ready breakouts with a voltage pump and they will be cheaper, who knows
gilded cradle
Yeah, perhaps
stuck elbow
@gilded cradle I'm trying your ST7789 display driver now, it should work now right?
gilded cradle
Yes, with Beta 6.
stuck elbow
I'm only getting a black screen, but the breakout I have is not the Adafruit one
gilded cradle
Ah ok. I've only tested with the Adafruit one. Can you link me the one you have?
Also, does yours work with the Arduino driver?
gilded cradle
oic
stuck elbow
your example should show a red screen, right?
stuck elbow
@gilded cradle which arduino library did you use for testing?
gilded cradle
@stuck elbow , I used the ST7735 and ST7789 driver. However, be aware that it only runs on an arduino and not a SAMD proc.
manic glacierBOT
stuck elbow
@gilded cradle ah, that would explain why it didn't work for me

What's the touch controller on pyportal?
gilded cradle
I believe it connects to some analog pins and uses the https://github.com/adafruit/Adafruit_CircuitPython_Touchscreen library.
exotic pumice
Thanks, but I'm curious to see a model # or datasheet
gilded cradle
You can find some more technical info here: https://learn.adafruit.com/adafruit-pyportal#downloads
gilded cradle
Yeah, sort of. It uses the ILI9341 display, but the touch is handled by the M4 Proc itself.
exotic pumice
2.8"?
gilded cradle
3.2"
exotic pumice
Oh
The only google result for the model # on that one is adafruit
Guess I'll just go off the lib
gilded cradle
What are you trying to do?
exotic pumice
Help someone build a library for the touchscreen in Rust
gilded cradle
Ah, which touchscreen? The one on the PyPortal?
exotic pumice
Yep
gilded cradle
Yeah, it basically checks the analog signal and uses that to determine where it's being pressed. Like you said, following the library would probably be the best course. 😃
exotic pumice
Yeah, I just like to get it from the source you know?
gilded cradle
Exactly. Plus you have all the numbers
I port stuff from Arduino to CP using a similar strategy.
exotic pumice
Sometimes there is stuff in the datasheet not in the code, but yeah, working off code is nice too
gilded cradle
True. I used 2 different arduino libraries plus the datasheet when I made the RA8875 driver, plus that was my first real CP library.
exotic pumice
Cool
exotic pumice
Does the same code work for resistive and capacitive touchscreens?
gilded cradle
No, it's just for resistive in this case.

Hello all, anyone can help me: Is rotaryio supported for the Trinket M0 yet?
stuck elbow
it should be easy to check if you have a trinket m0 at hand
tidal kiln
@hoary hill It does not appear to be. For core modules like that, you can check supported boards here:
https://circuitpython.readthedocs.io/en/latest/shared-bindings/index.html#support-matrix
rotaryio = SAMD51, SAMD Express
a Trinket M0 is a SAMD21 non-Express
tulip sleet
@hoary hill it is not supported only for space reasons. It would be possible to create a custom build that removed something else in favor of rotaryio
hoary hill
Thanks @tulip sleet and @tidal kiln , good to know the reason is space, I’ll see what I can do without of, in meantime will use the SAMD51 based board to prototype
tulip sleet
we actually made a bunch of room in the non-express builds in other ways, and might consider adding rotaryio for 4.0 if it's not too big.

To-Date: Took a break from CircuitPython to work on a couple of Eurorack module kits. Was nice to focus on therapeutic through-hole soldering again. Walked through some fun PyPortal projects, too.
Returned to CircuitPython this weekend to finish a collection of fundamental MIDI note utilities. The helpers translate a note descriptor string ’C#5’ to a note value (0 to 127), note values to a descriptor string, and a single helper that combines the two translators to permit “free-form” entry of either input form (note-to-name; name-to-note). I also threw in two more helpers for note-to-frequency and frequency-to-note calculations. https://github.com/CedarGroveStudios/MIDI_Util
To-Do: Next on the list is to complete one more rack module kit (mostly SMD soldering – fun, but not as therapeutic as through-hole) and do some CircuitPython coding.
Expect to wrap up a MIDI message decoder library using the full (memory-hungry) standard protocol stack and an optional lower-calorie version for essential messages. The decoder will include filters and triggers so that that only certain messages or sequences are decoded -- as an option to the default mode of processing all messages. Would be handy to be able to isolate or ignore a System Exclusive message block, for example. The decoder is the essential algorithm for analyzing received messages and will first be used in a 2nd-generation portable MIDI signal sniffer. With some tweaking, the decoder will also form the foundation of a general-purpose message builder for transmitting MIDI message sequences. Big thanks to the authors of “Data Structures and Algorithms in Python” for helping me achieve an enlightened approach to transforming the MIDI protocol into a Python-digestible structure. https://www.amazon.com/gp/product/1118290275
I've been watching his repo. Great progress!

Last Week:
-
nRF PDMIn: Changed buffer management to use a "static" double buffer in PDMIn.c for 2 reasons. 1) to test if my previous buffer management using the object's buffer was the reason for unusable output, and 2) to enable more inline manipulation for things like 8-bit samples (nRF periph is 16-bit only). The buffer switch caused no change for #1, so I took a break to complete some edX coursework on C pointers; wanted to make sure my shaky understanding wasn't the cause.
-
adabot "updated libraries" list: started formulating a plan for this.
This Week:
- PDMIn: Will start to implement the sinc filter to see if it fixes the output data.

@simple pulsar Yeah, I can appreciate that. For my sniffer code, memory isn't a primary issue. For performance, it becomes critical. I first designed the sniffer for the M0 (had a bunch of existing Trinket M0 MIDI projects), but am unapologetically moving to M4Ex boards now. I'm a Python beginner, so memory management is a basic challenge.

exotic pumice
why does PulseIO return an error over 6MHz?
raven canopy
that one i can't readily explain. i'd have to look deeper than i have...
raven canopy
@exotic pumice i'd say its related to setting the TC's TOP value: https://github.com/adafruit/circuitpython/blob/master/ports/atmel-samd/common-hal/pulseio/PWMOut.c#L233
TC is on DFLL @ 48MHz
Max prescaler = 8
48,000,000 / 8 = 6,000,000
TOP = 6,000,000 / frequency
6,000,000 / 6,000,000 = 1
so anything over 6MHz would require a change to the highest prescaler available. say...4 instead of 8.
hah. and i missed the - 1 at the end of the equation.
raven canopy
¯_(ツ)_/¯
exotic pumice
ok
gilded cradle
That looks great @crimson ferry.
raven canopy
@exotic pumice the best I could even think of at the moment is that it might be related to using the TCs in 16-bit mode. i'd have to run more mathing though...
quick math:
48,000,000 / 4 / 6,000,000 = 2
2 << 16 = no bueno for a 16-bit number
thanks for brainstorming anyway
raven canopy
err...wait. i was reading that line wrong. it isn't shifted. disregard.
exotic pumice
yeah I wasn't sure what you were doing there
exotic pumice
to be fair, I haven't read the code closely
raven canopy
it may have just been a design decision, not necessarily a limitation. but i don't have that answer. smarter people than i probably do, though.

for uncompressed video it would require pretty much as much power as animated gifs

perhaps instead of streaming the video, it could just take snapshots every 5 seconds

prime flower
@bold wind You could make a text-able status display for your desk, too, if you wanted
prime flower
As a desk-display, showing a bunch of data on it (stock ticker, some message/fortune/saying, etc)
for the camera, you can definitely stream images to it (if you have them stored somewhere retrievable online), and display the images on the PyPortal
bold wind
that would be easy 😃

FYI -- in case this comes up again -- in #help-with-projects someone was having problems with a DHT11 on a PyPortal - using the JST connector . I tried it on mine and found that a DHT22 worked fine, but a DHT11 was very unreliable (note, I have a 10K pullup on the data line - using D3). I then tried the DHT 11 on a PyPortal with the VCC jumper for the JST connectors set to 3.3V (instead of the 5V default) and now the DHT11 works very well (as does the DHT22) .

Big-5 is an encoding, not a font. But yes, the whole KJC character set is larger and more complex than most phonetic alphabets, and now I find myself wondering how they supported it back when big ROMs were expensive.

I've been doing a faintly related task myself, but decided to roll my own in Python because I'm that kind of a bear.
FRAM is a good choice: I was thinking an SD card, but that could get slow when rendering a bunch of characters.
fontio does do some preloading/caching, but it is a big character set.
upbeat plover
yeah chinese is huge, i fail chinese in highschool, speaking part wasnt hard, but remembering how to write everything is crazy... you have to be dedicated and write each character over and over many times till its like muscle memory

I can't wait to get started with circuit python.I recently bought a ItstyBitsy M0 and am waiting for it to arrive. Are there online emulators to try circuit python while I wait?
exotic pumice
@shy elm not that I know of.
but you can try regular python
and then all the circuitpython-specific stuff is hardware related
crimson ferry
@shy elm You will notice that some core modules have subsets of function (keeping the code lean and mean for small micros): https://circuitpython.readthedocs.io/en/3.x/shared-bindings/index.html#modules (or https://circuitpython.readthedocs.io/en/latest/shared-bindings/index.html#modules for the 4.x beta)

@river quest does a folder have to have a _ infront of it for it to be a liquid variable in jekyll?

@slender iron the second travis subjob on CPy is taking like 39 minutes; the next slowest is 33 minutes; if you're going to push another commit for your latest PR soon, maybe shuffle some boards in .travis.yml? I thought I counted them up, and they were all at 8 boards before pybadge was added, but maybe I was wrong. Some displayio boards could be mixed with non-display. The nrf builds are also much faster.
slender iron
ya, and the boards can vary a bit in build time too
tulip sleet
right, m4 vs m0 non-express, etc.

@tulip sleet feel free to have someone else finish your review. I'm out the rest of the night (getting my parents from the airport and then hardware happy hour)
tulip sleet
sure, thanks; I'm trying out the new USB-disconnected code from Thach. It looks like it can detect disconnect and reconnect nicely.
slender iron
nice!
tulip sleet
i'm switching a switchable data/power cable.
ok, have a nice night; you have plenty to show off!
slender iron
yup! byeee!

Just submitted a PR to the NINA firmware to support WPA2 Enterprise.
I'm out of time tonight, but I'm going to clean up the matching Adafruit_CircuitPython_ESP32SPI code I've got tomorrow and hopefully submit a PR for that before the end of the day

Guys, I just wanted to share my latest project with the community. Thanks to @solar whale and @gilded cradle for their help while I was working on the code part >
marble hornet
nice project @gusty topaz
solar whale
@gusty topaz nice! Thanks for sharing it!
gilded cradle
Thanks for sharing @gusty topaz. It's always nice to see the end result.

Guys, I'm trying to add my project to be featured on the next CP newsletter edition. I forked the repo
and made the changes to the draft file. How so I do a PR to the main adafruit repo? (first time doing it, sorry).

PSA: if you're going to "clone" issue text that references A LOT of other repos...don't. started working on some more enhancements. I apologize for any spammage and confusing references to sommersoft/adabot-travis-test spread about the GitHubisphere. 🤦
repo deleted. that cleans up the GitHubisphere. :phew:

very cool and nice and neat @gusty topaz How do you transfer the GPS coordinates to your pics?
I really need a 3d printer..
Sorry @gusty topaz I reread the article and see you tell how. Very nice article as well.
manic glacierBOT
Nice! Thanks for the fix. And now my hacks to adafruit_imageload seem to be working better also :)

@slender iron I'm having a brainstorm about the "Libraries" link on circuitpython.org. If you have time to chat sometime today, I'd like to discuss it with you.
idle owl
Ok great!

@idle owl ready when you are

@slender iron vid or audio?

I want a PyPortal and one of those amazing lux sensors from kattni to play with, also want a tinyfpga bx to start learning verilog.
ugh i ran-out of flash trying to put chinese on hallowing.... says -28 bytes so close... i guesss ill have to use a different font then the huge one i made
tulip sleet
@upbeat plover there are squeezy things to do to make it fit; hold on
upbeat plover
ooooo cool id like to learn
tulip sleet
in ports/atmel-samd/boards/hallowing_m0_express/mpconfigboard.mk, you can turn off some features, and you can also lower CFLAGS_INLINE_LIMIT. Try about 5 at a time. Lower than 35 or 40 can be a problem. But, for instance, you could set CIRCUITPY_ROTARYIO = 0 to take that out, and make room, or CIRCUITPY_SAMD (which only has specialized uses), etc.
see the other mpconfigboard.mk files for ideas about what to turn off
upbeat plover
oh cool yeah the first suggestion to remove would be good for me i dont use that ever
tulip sleet
there are lots of options
tulip sleet
@slender iron tnx!
raven canopy
@tulip sleet I think I know the answer to this, but is there a way we could also disable any certain translation(s) per board?
tulip sleet
no way now, we're trying to make sure all translations work on all boards
raven canopy
That's what I was thinking. Agree with the desire, just wasn't sure on the technically feasible part.
tulip sleet
The messages could be slimmed down in various ways, and we might be able to use a more sophisticated compression scheme, though I haven't found a ready-made library yet (I've asked: https://softwarerecs.stackexchange.com/questions/57255/in-memory-dictionary-based-compressed-strings-library)

im getting an error when trying to build hallowing with CIRCUITPY_ROTARYIO = 0
make BOARD=hallowing_m0_express TRANSLATION=zh
Use make V=1, make V=2 or set BUILD_VERBOSE similarly in your environment to increase build verbosity.

is that a transaltion error?
tulip sleet
@upbeat plover that has been fixed in the latest master; fetch and merge, and update submodules; it wasn't possible to turn off rotaryio. If you don't want to do that now, turn off CIRCUITPY_SAMD instead.
https://github.com/adafruit/circuitpython/pull/1745 is now merged
or lower CFLAGS_INLINE_LIMIT
upbeat plover
okay ill try just the limit cause im only needing 28 bytes
tulip sleet
just lower it by 5 and it will probably work
frail moon
this is probably a super dumb question, and someone will point that out quickly 😛 but my googlefoo seems to be failing me... how does one define an interrupt in CP?
tulip sleet
@frail moon we don't have interrupts or something like that (yet). MicroPython does, but there are severe restrictions, and we'd like to come up with a better way. There's discussion about this if you're interested: https://github.com/adafruit/circuitpython/issues/1380
We DO have native modules that use interrupts behind the scenes (e.g. PulseIn)
frail moon
oh... well drat. 😕 (guess I should figure stuff out like that BEFORE I design an element of my project around it. 😦 )
thanks
slender iron
@frail moon what are you trying to do?
frail moon
@slender iron I have one of the audiofx boards and when it's playing a sound the ACT pin goes low... so it was going to tell my board to keep the LEDs at full brightness until it stops playing, at which point they can go back to pulsing
maybe I don't need the interrupt though
slender iron
polling the pin should work too. it just may not be quite as responsive
slender iron
@tulip sleet to get the auto-close from github you need the "fixes #123" in a commit message, not a pr comment.
tulip sleet
It works if it's in the original (top) comment. I put that in by hand anyway for xref purposes, not expecting it to work. But thanks for the definitive answer.
slender iron
I think that is true because the top comment is used in the merge commit
manic glacierBOT
I checked the ST7735R datasheet and it says parameters are data. (See the D/C column below.)

SyntaxError: Missing parentheses in call to 'print'. Did you mean print("Skipping block at " + ptr + ")?

yes, it should be updated
