@slender iron thanks -- Travis works in mysterious ways...
slender iron
ya, probably just a bug
solar whale
some of my repos got migrated, some have not
cunning crypt
@slender iron So, I'm downloading CP 4 b0, and I'm just thinking - If it would be possible to sort the downloads, that would be amazing. Currently, there's... 8 languages and 36 boards (3 of which have both bin and uf2 downloads). 312 files is a lot to sort through, even if they are in a logical order.
slender iron
ya, we want to have a download site to make it easy
they are easier to grab from s3 actually
cunning crypt
That is so much nicer
slender iron
you'll want a newer one anyway. there are some good fixes checked in
cunning crypt
Any way you could have it so the 'Assets' is default 'closed' instead of showing everything? Or put at the bottom? It's a little intimidating, which is fine for an alpha/beta, but for standard releases not so much
Oh? Cool!
slender iron
I can't control the way github shows it.
for the stable release I want to have the website basics up
cunning crypt
Hmm, the S3 doesn't seem to have the latest files. from the 14th
Aha, the /ID folder, there we go
slender iron
thats the language
cunning crypt
There's a ton of "loose" files, then, in the main folder.
(Regardless, I've got the correct one)
cunning crypt
Good to know you've got plans
slender iron
ya, always have lots to do
cunning crypt
I'm sure! I'm going to go poke at the new display stuff and get out of your hair
slender iron
great! thanks. sorry for the grumpiness been working hard on displays and know there is still lots to do
cunning crypt
Don't worry, I didn't feel like you were being grumpy, more busy
slender iron
ok, cool 😃

Guys, I'm having issues with the Featherwing RFM95 lora. I have it on a tripler, at the top I have the M0 Express and the radio featherwing is in one of the open slots. When running the RFM95 example code that comes with the TinyLora library, I got the following:
code.py output: Traceback (most recent call last): File "code.py", line 32, in <module> File "adafruit_tinylora/adafruit_tinylora.py", line 150, in __init__ TypeError: Can not detect LoRa Module. Please check wiring!
I get the same error even if I put the featherwing in the other available slot on the Tripler. I can reset the M0 using the reset button on the featherwing and all the solder points seem to be well made. Any suggestions?
This is the featherwing I'm using > https://www.adafruit.com/product/3231
Crap... forgot to solder the IRQ and Cs wires....
lime trellis
is there anything firmware-wise I have to do to run a samd51 below 2.8V?
lime trellis
that awesome! can't wait to work with the portable console.
and I'll report back when/if I figure out why this thing is upset
gusty topaz
Guys, I'm looking to install CircuitPython on a Particle Xenon. Is this one the most updated guide? : https://learn.adafruit.com/circuitpython-on-the-nrf52/build-flash-particle
lime trellis
@gusty topaz that looks like it should work for you. Do you have a Jlink?
gusty topaz
No, that was going to be my other question. Do I need one if I go through Option 2?
lime trellis
Yes but you wont have a get out of jail free card if you get yourself stuck anywhere along the line
also, make sure you grab the latest Alpha 4.X build of circuitpython (per the adafruit page you linked)
gusty topaz
Sorry, you said that I still need a Jlink for "Option 2" in the description on how to install it on Particle Xenon?
lime trellis
Oops sorry I meant that yes you'll be able to program it via option 2 without a Jlink
gusty topaz
great, thanks!. I don't consider myself an expert, but I've dealt with Arduino, installing MicroPython on ESP8266 and I'm not afraid of the CLI. I think I'll give it a try (although I'm pretty sure I'll have questions).
lime trellis
give it a shot and feel free to ping me with questions 👍
gusty topaz
Thanks!
solar whale
but once loaded it works great 😉
gusty topaz
Well... since I already had the Particle Xenon, I was willing to install CP 4 on it. But since the JLink costs pretty much the same as the new feather nrf52840, I might as well just buy it if it comes ready to install CP on it (it's out of stock, though).
lime trellis
Is a Jlink required @solar whale ? or just a something monitoring SWDIO SWCLK as a debugger?
solar whale
I've only used a JLink -- and nrfjprog is expecting one as far as I know. There may be workarounds or other tools I am not aware of.
gusty topaz
So, ther eis no way of installing the UF2 bootloader only by using the mini-usb port on the Xenon?
solar whale
I don't know of one. That does not mean it can't be done.
gusty topaz
The guide makes reference to a debugger
Make sure your Particle is plugged into a debugger, and that both the debugger and the Particle are connected to the PC.
What exactly is that?
Never mind, I think it's referring to the Jlink.
solar whale
https://docs.particle.io/tutorials/device-os/led/xenon/ there is a DFU mode on the XENON and there "might" be a way to use it ...
but I don't think it is for loading a bootloader.
tulip sleet
I think that the bootloader that comes with the particle boards may require a signed update for the bootloader if you use DFU mode, for security reasons (I thought the Nordic bootloader was like that).
gusty topaz
that's too bad, I thought I was going to be able to play with the Xenon and CP4.
solar whale
The JLink has gotten me out of a lot of mistakes with bootloaders!
gusty topaz
And CP4 support for the bluefruit nRF52832 was recently dropped, right?
solar whale
yes
gusty topaz
(I have one of those laying around, still in its plastic bag).
solar whale
It does not support the uf2 bootlaoder at all
but it was possible to program via the DFU bootlaoder.
gusty topaz
hmm 😦
solar whale
even than -- it had no CIRCUITPY drive
it worked, but the new bleio module is not avaialble for it..
gusty topaz
got it.
lime trellis
@gusty topaz I carry around a segger JLink EDU mini ($18) since it's so small. and yeah they're great at saving your butt
gusty topaz
@lime trellis does it come with all the needed cables?
lime trellis
it comes with the tiny swd cable, but I use that with this adapter: https://www.adafruit.com/product/2094 so I can plug standard jumper cables in
solar whale
does Segger provide the 2x10 cable -- now Adafruit does -- originaly , you had to get it separately
gusty topaz
@solar whale I just noticed that, looks like Adafruit provides all what's needed to connect the Xenon. I'm now considering buying it (I'm about to place an order soon).
solar whale
oops wait -- you need the 2x5 cable --
gusty topaz
One key question: Is the Xenon planned to be formally supported by CP down the road or installing CP in it is just a cool experiment?.
solar whale
included ```This kit comes with a 20-pin (2x10) 0.05" cable and a 10-pin (2x5) 0.05" cable.
@solar whale the description of the product makes reference to that cable:
"This kit comes with a 20-pin (2x10) 0.05" cable and a 10-pin (2x5) 0.05" cable." are we talking a different cable?.
Got it.
solar whale
As to ongoing support, I have no idea. Good question though.
gusty topaz
@tulip sleet do you know anything about the Particle Xenon/Argon having official CP support down the road?
solar whale
Bed time here -- good night all 💤
lime trellis
night @solar whale
ah!!! found it! @slender iron
PSA: if trying to run CP on a samd51 <2.8V, you need to adjust the brownout detection
gusty topaz
Good night, thanks @solar whale

@gusty topaz We make our own Feather nRF52840 board that's "official" (and there will be more such boards. We're happy to include builds for other boards (and we do) in the CircuitPython source tree. But the main point of the Particle boards is to use their IoT service and software.
gusty topaz
@tulip sleet thanks, that makes sense. I was just wondering if builds were going to continue to be offered for Particle products.
valid falcon
I'm working on a pinewood derby car using the Hallowing and circuit python to control sounds and lights. I'm using the adafruit_lis3dh library to "feel" for different types of movement. The current triggers that set of different lights and sound are shake and when the car is tilted at a specific downward angle (meaning it's on the track and ready to race). I'd like to add the ability to know when the car is in forward motion and that is where I'm stumped. Anyone willing to point me in the right direction to recognize constant acceleration using the lis3dh library?
raven canopy
@valid falcon off the top of my head, you'll want to watch a combination of the z & y axis. while it descends the ramp, z should be positive and y should be negative. i would have to trial-and-error my way through the thresholds though...
valid falcon
Thanks @raven canopy . I'm good with trial and error. I'm thinking of trying lis3dh_free_fall too.
raven canopy
note: i swapped z & y. forgot that z was the vertical plane on the LIS.
solar whale
@valid falcon if I am thinking correctly, when you let the car go, it will "sense" a drop in acceleration in the direction "down the ramp" -- the extreme case is free fall.
so basically you are looking for a change in the acceleration being measured when it is let go.
meager fog
@umbral dagger hihi i have a bbspi q
valid falcon
@solar whale yep that's the goal. I think I'm close. Thank you.
main meteor
BBSPI? Bit-bang SPI?
meager fog
@umbral dagger p0ke 😃
umbral dagger
@meager fog Sorry... wasn't paying attention to this screen.
meager fog
@umbral dagger all good im writing esp32 code
so for the bitbang spi thing - i think we can do something simpler, we just make ab object with same interface as busio.SPI
but it uses digitalio underneeth
umbral dagger
Rather than base it on pigpio?
I.e. handroll the bitbanging on top of, say, gpiozero?
meager fog
@umbral dagger you can use digitalio like normal
blinka will automatically use libgpiod to do the digialio
hacking on esp32 in background
umbral dagger
@meager fog Ah. Ok.
meager fog
@umbral dagger then it'll work on other chips like OrangePi or onion io or whatnot

hi everyone, i'm starting with micropython on esp32 devkit board, and I would like to know what IDE is better to use, I tried with PyCharm but not support for esp32. What can you advise me ?
desert iris
Try uPyCraft (Windows) or simply adafruit-ampy, its still the best tool. Another great tool for Micropython is mpfshell. I like both ampy and mpfshell
foggy wyvern
yes I figured this out with ampy the first time I tried it I got an error. Now with the last firmware it's ok
thx for the help

exotic pumice
I soldered wires for swd to my cpx and now I can't use the bootloader, is that normal?
I get the green leds but no drive or ttyACM0
I don't have my swd device on me either 😦
do you think I overwrote part of the bootloader?
gilded cradle
The only time I've used the swd pins (on my itsybitsy m4) was to reinstall the bootloader because I had somehow erased it. I'm not familiar with how the cpx behaves without a bootloader, but it sounds like there's a possibility of that. Perhaps somebody with more familiarity can chime in?
exotic pumice
the bootloader is at least partially there because I can get red and green neopixels out of the reset button
but something's funky
gilded cradle
Yeah, mine had nothing light up except a short blip when plugged in.

General question on CP: Would the M0 Express running CP be able to handle a GPS Featherwing, OLED Featherwing and a Featherwing datalogger (microSD breakout)?
solar whale
@gusty topaz I serioulsy doubt it -- the SDCard module uses quite a bit of RAM as does the OLED.. I recommend upgrading to an M4.
gusty topaz
too bad, I already placed my order over the weekend 🤦🏻
hmmm but now that I think about it, I have a Paticle Xenon and I'm waiting on the Jlink to arrive to flash it with CP4.0. That, in theory should work. Right?
solar whale
yes -- it should work well.

I was working overnight on a project, and kept typing "make" as "amke", so I set an alias to it. The project was called "label", but as the night wore on, I started typing "lable", so I added that to the Makefile as an alternate build target.

Any comments on this?
analog_out.value = i```
Shouldn't it be
``` for i in range(0, 1024):
analog_out.value = i```or even for i in range(1024)
umbral dagger
Yes. Specifically the use of the analog output. Is it expecting valid values in the upper 10 bits and ignoreing the lower 6? That seems unlikely to me.

@main meteor My assembly time was 6502 and Z80. A tiny bit of 6800.
umbral dagger
I did a bunch of work on the Apple ][ line as well as lots of custom hardware. My Z80 work was pretty much all custom hardware.
exotic pumice
cool
raven canopy
@umbral dagger did you get your answer from above?
umbral dagger
I started out doing hardware; all my coding was in assembly other than the initial learnign using Basic.
@raven canopy That just seems to be how it is.
raven canopy
from the AnalogOut docs:
value
The value on the analog pin between 0 and 65535 inclusive (16-bit). (write-only)
Even if the underlying digital to analog converter (DAC) is lower resolution, the value is 16-bit.
Ok, that makes sense for a family of MCUs.
Each one scales based on the hardware resolution.
raven canopy
yeah. i'm not exactly sure why you'd be stepping by 64, but i'm sure the full context would explain that.
just did the math. makes sense now. 😆
umbral dagger
Yeah. I took that out of my example; the SAMD21 is a 10-bit converter, the '51 has a 12=bit.
raven canopy
open question: as a user, is 10ms an acceptable interval to get a new reading for frequency capture? values are much smoother & accurate at that rate, vs 1 & 5 ms....
exotic pumice
what does that make the max input frequency?
raven canopy
haven't gotten there yet. avoiding interrupts has been a challenge. 😄 with interrupts, i got up to 64kHz iirc.
exotic pumice
it wouldn't have helped me where I wanted frequencyin, but I found out pretty quick I needed a logic analyzer
raven canopy
correction..512kHz. 64 was with pulsein i think.
yeah, i haven't even started to compare again with the salaea. figuring out any adjustment is later.
exotic pumice
I got a $10 aliexpress jobby.

Does the business.
raven canopy
CTRLB.READSYNC is killing me. forces overflow before the count is updated. factor in the 4+ periods of latency between EIC->EVSYS...i've got math to google. hehe.
exotic pumice
syncbusy is the one that always gets me
raven canopy
oddly enough, i could never get the wait loop to trigger on it. though, it is still part of the condition.
exotic pumice
oops
I kinda wanna go to pycascades just to sit down with scott and get stuff figured out
raven canopy
hehe. figuring "stuff" out is good. 😄
exotic pumice
I'm only 3 hours from Seattle
raven canopy
math is off...but i'm feeding 4MHz so far with no affect on CP. "One small step..."
exotic pumice
you got 4MHz read in correctly?
raven canopy
well, its reading as 3.651063 MHz, but that is probably due to my mangling of the math.
exotic pumice
now that's useful
raven canopy
not locking up CP is my fav part.
raven canopy
hmm. PWMOut doesn't like anything above 6MHz. will probably need to use AudioOut for something of that magnitude. probably a good idea to compare square and sine anyway.
exotic pumice
use gclkio
it puts a gclk onto gpio
I can toss you a bin if you like, I already have it set up
or an elf
whichever is easier
raven canopy
bin works just as well. is it a static frequency, or can i change it?
and, 6MHz is reading out as 5.48...
exotic pumice
I'd have to recompile to change the clock speed
raven canopy
k. i won't turn down free testware at any rate. 😄
exotic pumice
what speed you want?
and 21 or 51?
51 is pretty broken atm
but I got 6mhz out of it
raven canopy
- 10MHz if you can. not sure anything in CP can get that high.
exotic pumice
is 12 ok? just easier math
raven canopy
12 it is!
exotic pumice
metro m0 or?
raven canopy
currently a feather m0.
haughty bobcat
@exotic pumice AliExpress is amazing
Adafruit is great too but I usually only get made in NYC dev boards because they are always so well designed. Everything else is AliExpress for me
raven canopy
hmm. just thought about "max". using a 16 bit TC, i can only count 65535 events per 10ms. need to find out if EVACT.COUNT triggers the overflow. that'll get me at least another 65535 events.
exotic pumice
just making a few changes for '21
should be 12mhz on d13
haven't checked myself yet
raven canopy
that...is spooky coincidence. i'm already using D13. 👀
and, thanks @exotic pumice! that'll come in handy as i tighten this up.
exotic pumice
not working for me unfortunately
raven canopy
@exotic pumice don't spend too much time fiddling. if you had 6mhz working, that one will do fine too. still a good alternative for testing. now, time to sit down with my brain-math-cells and new, steady data.
exotic pumice
I had 6 mhz on metro m4 but dan tried the same bin and got like 1.5 so I don't think that one is helpful
raven canopy
alright. i'll give the 12MHz one a go soon, and see what i get.
i mean, as long as i can get the actual output with the salaea, i can bounce results against it.
exotic pumice
oh, I know what it is!
I forgot I had to change something elsewhere to get this to work on m4
raven canopy
bit vs vec? i have so many #ifdefs for that. 😄
exotic pumice
this is rust, no, I have to enable io on the clock
inside the hardware abstraction library
now if only the docs would stop crashing my browser
tested working at 12mhz
bossac -e -w -v -b -R -o 0x2000 clock_out.bin
you guys should think about adding gclk_io support for circuitpython, all you have to do is set up a specific gclk depending which pin you're using, and then put the pin in function h on 21 or function m on 51
and have oe enabled on the gclk
want me to rewrite pulse_out?
not sure about the duty cycle bit
alternatively, FrequencyOut
maybe not a great idea considering how many gclks you guys end up using for other stuff
it's super freaking useful though
raven canopy
i'd talk to Scott or Dan about that. there may be room GCLK wise; just need to handle checking for availability.
i mean, the framework is there in samd-peripherals. with this new setup, i may even be able to abandon spinning up DPLL1 on the M4.
exotic pumice
Another atsamd-rs dev and I were wondering what you guys were using DPLL1 for
raven canopy
it isn't used at the moment on master. DPLL0 is, but i forget what its latched to. I grabbed it to fix accuracy when i was using the TC's "internal" capture; open DFLL was drifting the numbers badly.
raven canopy
might be...yep, main clock.
didn't want to boldly state it, since i couldn't remember for sure. 😄
exotic pumice
this is the stuff I've been working on for a while so I know it well
I even know that the ldr is 59 to make it 2.5x
raven canopy
i took such a long break from this, i forgot most of what i learned going though that. which was also the only time i've dug into setting clocks, so no other retention there.
exotic pumice
I think it's harder on atsamd than other vendors
raven canopy
if i could go back in time, i would force younger me to dig closer to the metal and not rely on all the high-level magic. ⏲
alright, brain shutdown time. 👋
exotic pumice
3-4x smaller binary cuz I was bored
exotic pumice
come to the rust side, we have small binaries.

@tulip sleet trying to reproduce the crash on the nrf52840 w/o USB -- so far it seems to work well
tulip sleet
It was really odd. I wasn't intentionally trying to do that. I just touched the USB plug to the socket when I was about to plug it in and it crashed. But it was hard to reproduce. This may not be related to the tinyusb code at all.
solar whale
are you tryin to connect to USB while it is running?
tulip sleet
yes, I wanted to see if it behaved ok in that situation
admittedly not something that would happen a lot in real life
tulip sleet
I had to do the tapping a dozen times to make it happen.
it might be static or something, though this room is not very staticky.

How do I fix "fatal: no tag exactly matches 'xxx'" I assume it is an out of date submodule but I can't seem to find the right git incantation.

@celest zenith try ```git submodule update --init --recursive
git submodule foreach --recursive 'git fetch --tags'
git submodule sync
or some combination of those incantations 😉

@slender iron is the usb-midi included in version 4 yet?
stuck elbow
it is
half pendant
I some how caused my Metro Express M0 CPU to start smoking. I unplugged it right away and removed all the wires I had plugged in. It has cooled down now, but every time I plug it back into my computer, the CPU starts heating up and the board doesn't show up in my file management window on my computer even when I put into BootLoader mode.
Any help?
The neopixel light is also red.
I think it might have been plugged into a bad 9V battery
Does anyone know of a way to save the board?
main meteor
It could be a power supply issue (like the voltage regulator), but I suspect that CPU chip is ruined, and the only way to fix the board would be to replace the CPU. If you have hot air rework facilities and a source of SAMD21 chips, it should be doable but somewhat fiddly.
half pendant
that is way over my head. bummer.
exotic pumice
@slender iron should I add FrequencyOut to my list?
main meteor
That was a nice thing about the original DIP Arduinos: it was easy to unplug the CPU chip and replace it.
half pendant
The DC jack doesn't work anymore, but the board still powers from my computer. Does that mean that the problem was through the DC jack?
aka the battery?
main meteor
Hmm. When you said "every time I plug it back into my computer, the CPU starts heating up", I figured it didn't work from the computer.
It may be the DC power circuitry then.
half pendant
The board turns on with the USB, but i cannot get it to do anything and the CPU starts getting really hot.
Do you still think it is a lost cause?
manic glacierBOT
main meteor
Sadly, that seems the most probable to me. 😦 Perhaps someone else here more familiar with the board may have a better idea.
half pendant
okay. Thanks anyway.
manic glacierBOT
raven canopy
stable again! now time to work out the delta. :phew:
slender iron
@exotic pumice I don't think we need a frequencyout. pwmout should be able to do it
exotic pumice
ok, just thought maybe for higher frequencies
gclk_io can do any speed the gclks can, like 120+ MHz
and it's super easy to set up, but if you don't think it'd be useful I understand

Anyone want to test out a bit-bang SPI library for RaspPi & the like (I.e. using blinka) ? https://github.com/dastels/adafruit_python_bbspi
Bundled in that repo is example code for the BME280 but it'd be good to see it working with other sensors, especially using modes 1 & 2. (The BME280 can use 0 & 3, which it's bee tested with)
slender iron
<@&356864093652516868> My plan is to stream debugging tomorrow afternoon starting around 2pm Pacific.
marble hornet
@slender iron I don't know how many HS students are in here but we often get our right at 2:00. I'll be able to come but that is a very popular dismiss time in and around mass
Just to put it out there: I don't think too big of a concern
slender iron
I'm thinking it'll be 2-3 hours so you should be fine
solar whale
@slender iron where will the stream be -- any special tools/acoounts needed to access?
ohh -- just realized its at 2PM PST -- may not work, but I'll see. No worries...
solar whale
@umbral dagger will try to find time to try the bbspi tomorrow or over the weekend.

Oh @solar whale, been that way for far too long! 😛

Oof, I hate tests that are basically mindreading tests.

I've taken enough of them to know exactly what I was getting into. And this is one of the more comprehensive ones we have.
Normally a 40 hour class + tons of study. All on one's own.
But it is DONE. 🎊🎉
solar whale
@umbral dagger I'm a bit confused. does using the bbspi require a modified version of each sensor library? I see you have one for the bme280.
umbral dagger
That's TBD
The thought at the moment is that the module will be adafruit_bitbangio

@slender iron on Hallowing with PR_1513 should anything be seen on the screen at boot?
slender iron
ya, I think so
solar whale
hmm -- I did not see anything -- what should I expect?
solar whale
ok -- no rush -- just curious -- displayio is kind of mysterious to me ....
slender iron
ya, I realize I haven't taught it well
ya, I see what its missing
in code.py you can do board.DISPLAY.show(None)
slender iron
yup, it's built in display handles it now
so you don't need to pass it into slideshow
you'll want the latest slideshow lib too https://github.com/adafruit/Adafruit_CircuitPython_Slideshow/
solar whale
ok -- I'll do some updates - BTW using code.py with just ```
import board
board.DISPLAY.show(None)
hrm, it should at least show the blinka. lemme brush my teeth and then I'll try it
solar whale
ok -- sorry for all the intteruptions -- no rush
solar whale
ok -- will try in about 5 min
slender iron
kk
solar whale
hmm -- sorry - still don't see anything - should I have code.py or no with this build?
solar whale
@slender iron not having much luck I also do not se anythin on screen when I run this ```import board
from adafruit_slideshow import PlayBackOrder, SlideShow
import pulseio
Create the slideshow object that plays through once alphabetically.
slideshow = SlideShow(board.DISPLAY, None, folder="/",
loop=False, order=PlayBackOrder.ALPHABETICAL)
while slideshow.update():
pass
weird
slender iron
What it does for me
solar whale
great song!
slender iron
haha, 😃
solar whale
do I need anythin on the board besides slideshow.mpy
slender iron
it shouldn't need anything
solar whale
and my .pngs
solar whale
just erased filesytem and rebooted -- nada
ooohh -- it works on battery!!
not on USB!
slender iron
hrm, that's weird
solar whale
now it is working on USB --- very odd -- just had to unplug
slender iron
possible the display got unhappy
looks to see if we software reset the display
yup, looks like we try to
solar whale
ok -- slideshow works now too ...
was your build from pr 1513 as is or did you have to fix something?
nevermind -- just pulled/built master -- works fine!
slender iron
ya, I think its stock
solar whale
thanks for the help -- guess it just needed a power cycle
solar whale
@tulip sleet do you have a simple example of what the new BUTTON_x definitions are used for -- I'm just not seeing it ... the pythonic side of my brain is not working.
idle owl
@solar whale I think like this, though I haven't tested it: ```from adafruit_ble.uart import UARTServer
from adafruit_bluefruit_connect.packet import Packet
from adafruit_bluefruit_connect.button_packet import ButtonPacket
uart_server = UARTServer()
while True:
uart_server.start_advertising()
while not uart_server.connected:
pass
# Now we're connected
while uart_server.connected:
if uart_server.in_waiting:
packet = Packet.from_stream(uart_server)
if isinstance(packet, ButtonPacket):
if packet.pressed:
if packet.BUTTON_1:
# The Up button was pressed.
print("1 button pressed!")
elif packet.BUTTON_2:
# The Down button was pressed.
print("2 button pressed!")
# If we got here, we lost the connection. Go up to the top and start
# advertising again and waiting for a connection.
or it might even eliminate the packet.pressed, I haven't checked
solar whale
ah OK -- but the old way of packet.button == '1' still works -- just add the new .BUTTON_1 is an option
idle owl
I believe so yes.
solar whale
thanks -- now I'll go back and look at the code to see if I understand it better ...
solar whale
hmm tried a quick test and all presses act like BUTTON_1 -- I may be doing it wrong ...
tulip sleet
no, should be packet.button == ButtonPacket.BUTTON_1. It's just a name for the string "1"
maybe I messed up the example?
solar whale
there is no example, is there?
tulip sleet
uh, no, sorry
solar whale
np
solar whale
ok --long winded way to type '1'
tulip sleet
right, because nobody knows that "5" is UP
solar whale
😉
idle owl
Ah.
tulip sleet
without looking at the Bluefruit LE Connect guide
solar whale
now I get it!!
tulip sleet
could do a from ButtonPacket import *, but I don't think it's worth it
solar whale
OK -- now it works 😃
What causes a "Reload Exception" I often get one after reboot -- just once then no more
slender iron
the os writing to the disk
solar whale
oh -- not waiting long enough after copying new file I guess
slender iron
just using that instead of a keyboard interrupt you don't trigger
solar whale
ok - but I copy a new code.py -- it reboots -- I connect my bluetooh app then it does the reload trap and reboots - and disconnects
does it always reboot twice?
usually not connected to see it.
slender iron
it depends on the os

solar whale
for the initial startup -- based on an old example from Scott -- may not be fully up to date - but it works
for the text writing demo - I had to modify adafruit_display_text.py to change Sprites to TileGrid then I ran this to print some text, make a box, move the text, change colors. again based on a possibly outdated example - your mileage may vary 😉
I ran display.py as my code.py
