#

woohoo!

unreal ginkgo Mar 27, 2018, 9:25 PM

#

i would imagine that the neopixel ring works about the same as the neopixels on the playground express with certain code
but i'm not sure how the individual pixels inbetween would work

slender iron Mar 27, 2018, 9:26 PM

#

@unreal ginkgo the same code will work, its just a different shape

unreal ginkgo Mar 27, 2018, 9:26 PM

#

yeah, i think it's more of an understanding thing

jovial pine Mar 27, 2018, 9:27 PM

#

It worked!!! Thanks for everyone's help. If anyone's interested in a atsamd21e18 based chording (18 key) keyboard let me know....

unreal ginkgo Mar 27, 2018, 9:30 PM

#

so with a few individual lights between the playground and the ring, cycle would kinda just be lights moving from one end to the other?

slender iron Mar 27, 2018, 9:31 PM

#

the first ten would cycle colors

unreal ginkgo Mar 27, 2018, 9:31 PM

#

ahhhh

slender iron Mar 27, 2018, 9:31 PM

#

since hte circuitplayground has 10

#

its not actually moving a color from one pixel to another. they are all doing the same pattern but at different positions

unreal ginkgo Mar 27, 2018, 9:33 PM

#

yeah, but it's just easier to understand that way for me i guess

slender iron Mar 27, 2018, 9:33 PM

#

np

unreal ginkgo Mar 27, 2018, 9:35 PM

#

so to do something like cycle would the playground, individual lights, and light ring be coded in separate parts?

slender iron Mar 27, 2018, 9:35 PM

#

it all depends on the pattern

#

if you care about the position of the neopixel it'd be hard to share

#

if you only care about the index then its easy

unreal ginkgo Mar 27, 2018, 9:38 PM

#

just kinda alternate between 2 colors between every other pixel is the most im gonna be doing
i think that's the right wording?

slender iron Mar 27, 2018, 9:38 PM

#

yeah, that makes sense

#

that would work for them all

unreal ginkgo Mar 27, 2018, 9:38 PM

#

alright, thanks

#

it's easier to get the hardest thing out of the way now

slender iron Mar 27, 2018, 9:39 PM

#

😃

unreal ginkgo Mar 27, 2018, 9:39 PM

#

my only other problem is the memory on the circuit playground express

#

there's a handful of audio files i'll be using and i'm hoping there's enough space

slender iron Mar 27, 2018, 9:41 PM

#

yup, that'll be trickier

unreal ginkgo Mar 27, 2018, 9:44 PM

especially when the one is 16 seconds long

#

I kinda what to change every assert() about an object type into an exception instead. lots of the findings from afl are type errors that cause assertions instead of python exceptions..

#

because who would ever have thought to write A.__new__(ValueError)! only bad people who should feel bad, and afl-fuzz.

stuck elbow Mar 27, 2018, 10:16 PM

#

oh, you use lcamtuf's toy?

onyx hinge Mar 27, 2018, 10:39 PM

#

@stuck elbow yes, have a look at https://emergent.unpythonic.net/01522108310 for my process

stuck elbow Mar 27, 2018, 10:40 PM

#

ah, it's the unix port, that makes things considerably easier

onyx hinge Mar 27, 2018, 10:40 PM

#

right. Some of the bugs are specific to the unix port, most will crash the real circuitpython hardware though.

#

when it comes to assertion errors, I think NDEBUG is defined for the usual builds so in that case it'll blithely continue and do something that should have been impossible.

#

The distilled testcases I'm chasing down now: https://emergent.unpythonic.net/files/sandbox/more-afl-circuitpython-findings.txt

stuck elbow Mar 27, 2018, 10:42 PM

#

usually it will just crash a few instructions later

#

in practice

tulip sleet Mar 27, 2018, 10:44 PM

#

@onyx hinge we defined NDEBUG because otherwise we run out of flash

#

maybe it's not quite so tight now, but we'll fill it up again 😃

#

it's good to throw exceptions, but maybe we shouldn't use up flash bytes for a lot of exception strings that are extremely rare. Perhaps we could return numeric codes instead for very rare exceptions.

stuck elbow Mar 27, 2018, 10:47 PM

#

or even have something like ImpossibleHappened exception as a catch-all

onyx hinge Mar 27, 2018, 10:47 PM

#

SystemError would be the standard for that

tulip sleet Mar 27, 2018, 10:48 PM

#

and it's true throwing exceptions is like turning off NDEBUG in terms of space. Well, it's not impossible, just very improbable. A lot of these could be ValueError.

stuck elbow Mar 27, 2018, 10:48 PM

#

"Please restart the universe and try again."

onyx hinge Mar 27, 2018, 10:48 PM

#

just carrying the bytes to perform all those checks will count for something. NDEBUG doesn't even evaluate the assert condition, so the code is dead/optimized out

stuck elbow Mar 27, 2018, 10:49 PM

#

there is definitely a balance to strike there

tulip sleet Mar 27, 2018, 10:49 PM

#

we could put in exceptions and then #if MICROPY_VERY_RARE_EXCEPTION them out in small builds.

#

something like that

#

@slender iron worth reading 2:59pm (PT) and following above

onyx hinge Mar 27, 2018, 10:55 PM

#

    yield from g
g = gen8()
print(next(g))```

#

well I can see why this doesn't make circuitpython happy!

#

python3's able to state ValueError: generator already executing

slender iron Mar 27, 2018, 11:10 PM

#

thanks @tulip sleet I'll read back now

#

@tulip sleet @onyx hinge any idea how much code size increase it'd be? I'm all for tightening the checks

#

does anyone have example code for the st7735r on cp

#

I'm trying to use adafruit_rgb_display and am running into problems with actually sending anything to the display. after i make an instance of ST7735R I cant .fill() or .pixel() code i used:

#

from adafruit_rgb_display import color565
from adafruit_rgb_display import st7735

#setup a spi  interface using the hardware spi
disp_spi = busio.SPI(clock=board.SCK, MOSI=board.MOSI, MISO=board.MISO)

#make digital pins without making
#it too long to copy and paste into repl
def make_digipin(pinput):
    return digitalio.DigitalInOut(pinput)
    
# setup a dislay pbject that can be adressed
#disp = st7735.ST7735(disp_spi, cs=digitalio.DigitalInOut(board.D9),dc=digitalio.DigitalInOut(board.D13), rst=digitalio.DigitalInOut(board.D12))
disp = st7735.ST7735R(disp_spi, cs=make_digipin(board.D9), dc=make_digipin(board.D11), rst=make_digipin(board.D12))

disp.reset()

disp.fill(63488)

time.sleep(1000)

disp.reset()

disp_lite = pulseio.PWMOut(board.D13)
disp_lite.duty_cycle = 2 ** 15

disp.reset()

disp.fill(63488)

#

but .reset() works

#

any suggestions

#

and the PWM works b/c the backlite is not at 100%.

#

HELP please

#

@cunning crypt thank you for the example code for the st7735R it really helped!!!

#

got it working!!!!

#

sorry for the plea for help

#

what i ended up using:

#

from adafruit_rgb_display import color565
from adafruit_rgb_display import st7735

disp_spi = busio.SPI(clock=board.SCK, MOSI=board.MOSI, MISO=board.MISO)

disp = st7735.ST7735R(disp_spi, cs=digitalio.DigitalInOut(board.D9), dc=digitalio.DigitalInOut(board.D11), rst=digitalio.DigitalInOut(board.D12))

#display.fill(color565(255,0,0))


while True:
    time.sleep(2.5)
    print("RED")
    disp.fill(color565(255,0,0))
    disp.pixel(1,1,color565(0,255,0))
    time.sleep(2.5)
    print("BLUE")
    disp.fill(color565(0,0,255))
    disp.pixel(1,1,color565(0,255,0))
    time.sleep(2.5)
    print("black")
    disp.fill(color565(0,0,0))
    disp.pixel(1,1,color565(0,255,0))

Is redirecting the REPL output such as print really the right way? Wouldn't something like basic logging support be more like CPython? Exceptions could be caught and logged then.

something to test if that happens on other display drivers (i don't have any other displays to test this on, just the 1.8 inch adafruit st7735r breakout)

yeah. you can get there from the "builds"... I learned to get to the backend log from adabot. http://readthedocs.org/api/v2/build/6954985/

[adafruit/circuitpython] New comment on pull request #710: Assertion failures to exceptions

Could you make the error message more specific? E.g., in CPython:

>>> type('abc', None, None)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: type() argument 2 must be tuple, not None
>>> type('abc', (), None)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: type() argument 3 must be dict, not None

I don't think you have to say "not blah", but "must be blah" is helpful.

i saw you put in a commit for the trinket dotstar PA01 in use thing. in the commit message you mentioned that you got it "statusing".... did you mean full status fix, or still just the purple pixel?

pastel panther Mar 28, 2018, 3:50 AM

#

I mean that it generally appeared to not be in an error state and generally correctly reflected the state (REPL, exception, running etc.)

#

I'm not familiar with the range of messages it's supposed to send and when so I don't know that it was working correctly in every situation

#

as a side note, you can always feel free to private message me if you have a question and I'll get to it when I can

#

same goes for anyone who might read this

#

(or @mention me)

#

(or send pidgeons)

raven canopy Mar 28, 2018, 3:53 AM

#

hmmm. i applied your changes to my local repo, and it's still not acting right.. maybe i should pull on a whole new branch. and order some pidgeons...

how is you repo different from master?

Here's an oddity. After testing for Purple Pixel, I left the main.py with just the line # this is an empty program in Mu. Reset Trinket with the button, status starts flashing blue. main.py now reads { 8 1 8 1 0 6 E 0 - 2 4 A in IDLE... And just { in Mu.

#

Replicated. Just a different number this time...

#

Must just be that board (has the new uf2). My spare trinket doesn't replicate. Could it be the new uf2?

@siddacious, I would have tested this before commenting, but didn't think about it until this morning on the way to work.

When you built the firmware, did you use DEBUG=1? It's the only differentiation I can readily think of (I built with debug on). Seems like a longshot, but figured I'd ask...

tidal kiln Mar 28, 2018, 2:26 PM

#

what's causing this behavior? (guessing it has to do with how many bits are being used for float)

Adafruit CircuitPython 2.2.4 on 2018-03-07; Adafruit Itsy Bitsy M0 Express with samd21g18
>>> "{:f}".format(4444)
'4443.999767'
>>>

solar whale Mar 28, 2018, 2:35 PM

#

@tidal kiln - if you plug both values 4444 and 4443.999767 int this tool, it shows that they have the same stored representation. https://www.h-schmidt.net/FloatConverter/IEEE754.html

#

even for a 32 bit float!

#

wahts different is that CP call it 4443.999767 and regular python calls it 4444

onyx hinge Mar 28, 2018, 2:56 PM

#

@tidal kiln Desktop Python typically uses "double precision" floating point, while CircuitPython typically uses a modified version of "single precision" floating point. I believe that CircuitPython floating point numbers only have around 6 digits of precision (two bits lower precision than the values you can play with on that link from @solar whale), while desktop python has something like 17 decimal digits

anyone know the significant difference between the LSM9DS0 and the LSM303. I can't get my LSM9DS0 to calculate a heading properly (even after following many tutorials and reading guides)... do i need the LSM303?

@tulip sleet yep. that's the issue. i've been playing around with it, tried that:

"working code" is such an unrealistic goal. It's code, you're working on it. therefore it's working code... 😉

I think it's the NeoPixels....

I managed to get everything working again

#

And swapped the new ones back in, had to use the other ground wire instead of the one that is connected to the actual jst connector to even get it to do anything, and it is now doing weird things like it's getting erroneous data

#

Maybe the stock wiring is bad?

#

It's a full reel so it has connector on both ends already

I absolutely assumed it was me

the data connection to them may be flaky because your logic level is 3.3v

fyi purple is the default pixel color out of bootloader so it may mean your pixel isnt working at all

errant grail Mar 28, 2018, 5:39 PM

#

The resistor is just for protecting the first pixel on the strip. A value around 470 ohms is usually used, but that's too high when sending 3v data to 5v neopixels. So that's not an issue in your case.

#

The Trinket's 3v regulator can only supply 150mA. Suggest connecting the neopixel power to the battery instead.

The sockets are nice. The pins on the IC are pretty thin compared to typical header pins and easy to bend when inserting into the breadboard.

That's right...

#

So back to earlier NeoPIxel issue

#

if I'm running pressing the button that makes them light up, repeatedly, and it every so often ejects and resets the whole board, I'm probably still trying to power too many NeoPixels at once?

#

Or resets the board and ejects. Wrong order in the first statement.

raven canopy Mar 28, 2018, 6:57 PM

#

Yeah, you might be hitting the brownout for the chip. If your status pixel is working, brownout is orange....I think.

idle owl Mar 28, 2018, 6:58 PM

#

bugger.

#

Frustrating because the strip of 120 worked great on 5V, no issues, incredibly consistent etc.

errant grail Mar 28, 2018, 7:06 PM

#

It's really easy to overload the 3V output on the Trinket when using NeoPixels. Just three at full brightness will start to tax the regulator circuit. If you reduce overall brightness significantly, you may be able to use it to test software functionality.

#

BTW, there's a good example of buffer chip wiring linked from the product page. The example is for a RPi, but the wiring is fundamentally the same.

idle owl Mar 28, 2018, 7:09 PM

#

Ok yeah if I hold it at full brightness, it ejects the chip and resets

errant grail Mar 28, 2018, 7:10 PM

#

NeoPixels and the Trinket work more reliably with the buffer, as 470-ohm resistor in series with the buffer output and the data input of the neo strip, and a hefty capacitor on the neo strip's 5v power supply. In my latest design, I used a 220uf capacitor successfully.

idle owl Mar 28, 2018, 7:10 PM

#

Are NeoPixels always flaky with 5V? So was it coincidence that my first strip worked perfectly?

errant grail Mar 28, 2018, 7:12 PM

#

This uses an SMD version of the buffer chip. The cap is to the left of the Trinket M0.

📎 DSC05068a_lores.jpg

idle owl Mar 28, 2018, 7:13 PM

#

Ah ok

errant grail Mar 28, 2018, 7:13 PM

#

Neos aren't flakey with a 5v supply if the data input is also driven to 5v. That's why the buffer is needed. Some folks claim that reducing the neo strip voltage to 4v lowers the first neo pixel's data threshold to work better with 3.3v, but that's not supported by the vendor specs.

idle owl Mar 28, 2018, 7:13 PM

#

But I was running the 120 off of the same chip, same setup, same code.

errant grail Mar 28, 2018, 7:14 PM

#

With a 5v supply to the neo strip? From the same source as the USB power to the Trinket?

idle owl Mar 28, 2018, 7:15 PM

#

yes

#

Trinket is plugged via USB into a powered USB hub

#

had it on the USB pin

#

(ergo my confusion)

errant grail Mar 28, 2018, 7:17 PM

#

You were lucky. The neopixels just don't respond predictably to data input lower than a 5v swing. Minor things like cable length and/or quality of the solderless breadboard connections can cause problems.

idle owl Mar 28, 2018, 7:17 PM

#

Bugger.

#

Ok

#

😃

raven canopy Mar 28, 2018, 7:18 PM

#

Chip version diffs? IIRC the SK's are a little more tolerant than the WS's...

idle owl Mar 28, 2018, 7:18 PM

#

Also possible, they're different densities, and one was a side-light strip

errant grail Mar 28, 2018, 7:19 PM

#

I had particular problems with an older-generation neo just 2 inches away from that controller. The newer-gen 60 element side-light strip worked fine 10 feet away. I put in the buffers to fix the old-gen problem and to increase reliability of the 60-element strip.

#

@raven canopy definitely. However, I believe the specs still encourage a 5v swing on the data input for reliable operation.

idle owl Mar 28, 2018, 7:24 PM

#

and how you're powering the Trinket is irrelevant to what the 3V can handle?

#

It's limited on its own?

errant grail Mar 28, 2018, 7:24 PM

#

@idle owl density shouldn't matter for the data line. Power consumption increases, though.

#

yes. The 3v output passes through a regulator chip on the Trinket board. The regulator chip gets its power from the USB connection.

idle owl Mar 28, 2018, 7:25 PM

#

I realise that, I meant that the higher density ones might be different chips. And they're the sidelight ones, which are much newer.

#

Ok thank you

#

Still trying to come up with workarounds 😄

#

We've covered what they are, I keep hoping there's something simpler.

errant grail Mar 28, 2018, 7:26 PM

#

Yes, I suppose the high-density strips could use a different chip, but I don't know that for certain.

#

I understand wanting to find a simpler workaround! Been there a few times!

idle owl Mar 28, 2018, 7:27 PM

#

I don't know either. Was basically stating the differences to say the chips could be different, I wouldn't know 😄

errant grail Mar 28, 2018, 7:27 PM

#

😃

idle owl Mar 28, 2018, 7:29 PM

#

Wait, so how does the 5A external power supply work with NeoPIxels? I've never had an issue there either

errant grail Mar 28, 2018, 7:29 PM

#

Bottom line is the neo pixel data line is a relatively high-speed data transfer connection that needs some special care and feeding.

idle owl Mar 28, 2018, 7:29 PM

#

So the ones that use a barrel jack

#

like on Metro

#

except not 9v

errant grail Mar 28, 2018, 7:30 PM

#

As long as the strip and Trinket or Metro share a common ground, the data line has a reference. The power to the neos can then come from any source.

idle owl Mar 28, 2018, 7:30 PM

#

but that supply isn't 3V. is that because it can be whatever the power consumer needs?

ruby lake Mar 28, 2018, 7:32 PM

#

if you use a lot of pixels use a power supply at each end

#

my 300-pixel string above the garages uses two 50W bricks

errant grail Mar 28, 2018, 7:33 PM

#

Yes, if I understand what you're saying. The neos like 5v power (and lots of it in some cases), so a separate power source is always the safest bet. In the case of my recent controller project, I use a hefty 5v supply that feeds the neo strip and the USB pin on the Trinket M0.

idle owl Mar 28, 2018, 7:33 PM

#

@ruby lake I don't think that's practical for this project, but really good to know in general

#

How is power getting to the Trinket in your thing?

errant grail Mar 28, 2018, 7:34 PM

#

So the Trinket M0 and neo strip get 5v power from the same source. I'm not using the USB connector for power in this case, just for programming.

idle owl Mar 28, 2018, 7:34 PM

#

ok

errant grail Mar 28, 2018, 7:35 PM

#

You can put +5v on the board's USB pin and power it that way. Doesn't have to come from the USB connector.

idle owl Mar 28, 2018, 7:35 PM

ohhh

ok

#

idle owl Mar 28, 2018, 7:36 PM

If you look closely at the photo I posted earlier, you can see the trace that connects between the +5 input that the barrel jack running to the USB pin of the Trinket board.

errant grail Mar 28, 2018, 7:40 PM

#

That 5v input also travels across the top of the board to the neo strip's wires. It's shared by the Trinket and the strip.

#

It's a pretty hefty board trace in order to handle the current load of the strip.

idle owl Mar 28, 2018, 7:42 PM

#

ahh ok

#

I would have missed it because it seemed more like silkscreen than trace at that size

errant grail Mar 28, 2018, 7:44 PM

#

I also ran a similar trace in parallel on the bottom side of the board to double the capacity. Wanted these controller boards to work with very long strips, if needed.

#

Don't have any extra PCBs right now, or I'd send you one. I might order another batch in a couple of months if the budget allows...

Thanks much!

marble hornet Mar 28, 2018, 7:57 PM

#

@idle owl i though you did some work on the rgb_dispaly library for circuit python. do you know of a way to rotate the display ?

idle owl Mar 28, 2018, 7:57 PM

#

I did a lot of testing and bug finding. I don't know how to manipulate it like that. 😃

marble hornet Mar 28, 2018, 7:58 PM

#

@idle owl thanks anyway! may i ask about the back story for your name?

idle owl Mar 28, 2018, 8:03 PM

#

@marble hornet The sweetest friend from my first ever job wrote me a note one day and addressed it to Kattni. I went by Katt at the time. A couple of years later I decided to change it up and Kattni's what I went with. It's the name I go by in general, not just my online name.

#

I haven't talked to him since before I started using it, so he doesn't even know he named me 😄

marble hornet Mar 28, 2018, 8:07 PM

#

@idle owl thanks for the story. how do you like it pronounced ?

idle owl Mar 28, 2018, 8:08 PM

#

Cat like the animal, knee like the joint in the leg. Which is how I describe it when people don't understand me when I introduce myself. Including gestures which don't translate well to text... like petting a cat and then point at the knee. It usually works 😄

marble hornet Mar 28, 2018, 8:09 PM

#

how about cat like the animal then "nee" like what the knights say ?

tidal kiln Mar 28, 2018, 8:09 PM

#

huh. i thought it was ni, as in the knights who say.

#

oop. 2 slow.

marble hornet Mar 28, 2018, 8:10 PM

#

@tidal kiln great minds think a like

#

does anyone know about framebuf? im trying to find how to read from a pixel ?

idle owl Mar 28, 2018, 8:15 PM

#

@tidal kiln @marble hornet Most of the people who would get the reference don't need the extra explanation 😄

tidal kiln Mar 28, 2018, 8:23 PM

#

do we have a flash eraser for itsy bitsy?

marble hornet Mar 28, 2018, 8:23 PM

#

please explain again how sheep's bladders can be employed to prevent earthquakes or how one can look at the color of a pixel from framebuf ?

#

of a wiki with information, i haven't found anything online?

tidal kiln Mar 28, 2018, 8:28 PM

#

@marble hornet i haven't actually worked with it, but i'm seeing a pixel function:
https://github.com/adafruit/Adafruit_CircuitPython_RGB_Display/blob/master/adafruit_rgb_display/rgb.py#L119

solar whale Mar 28, 2018, 8:28 PM

#

@tidal kiln If there is not, you can just change this line https://github.com/adafruit/circuitpython/blob/master/ports/atmel-samd/supervisor/filesystem.c#L62 to if ( create_allowed) { create a special version that will always create a new FS.

micropython-adafruit-framebuf - Pure python implementation of MicroPython framebuf module. Useful for boards with limited flash memory that cannot use the native C framebuf module.

#

but im having trouble

tidal kiln Mar 28, 2018, 8:30 PM

#

looks like there's also a pixel function there:
https://github.com/adafruit/micropython-adafruit-framebuf/blob/master/framebuf.py#L90

marble hornet Mar 28, 2018, 8:30 PM

#

it seems like a lot of the internal function of the RGB565Format class that is passes but i cant see where it is defined 'fb"

tidal kiln Mar 28, 2018, 8:31 PM

#

the .format member is an instance of either MVLSBFormat or RGB565Format

solar whale Mar 28, 2018, 8:31 PM

#

@marble hornet take a look at https://circuitpython.readthedocs.io/en/programming_guide/docs/library/framebuf.html

marble hornet Mar 28, 2018, 8:31 PM

#

@tidal kiln i have looked at the rgb_dispaly but I am looking for something with support for text and rotating the display.

tidal kiln Mar 28, 2018, 8:31 PM

#

each of those has a getpixel method

#

which get's called if you pass in None for color:
https://github.com/adafruit/micropython-adafruit-framebuf/blob/master/framebuf.py#L94

#

(or just don't specify color)

solar whale Mar 28, 2018, 8:34 PM

#

@marble hornet what board are you using? Express boards have the "full" framebuf builtin

#

I think "rotate" is a physical operation 😉

marble hornet Mar 28, 2018, 8:37 PM

#

so if i make an instacne of a frame buffer?

#

fbuf = framebufFrameBuffer(bytearray(10 * 100 * 2), 10, 100, framebuf.RGB565.FrameBuffer(bytearray(10 * 100 * 2), 10, 100, framebuf.RGB565)

#

then call fbud.getpixel(self, fb, x, y) what is that fb term????

tidal kiln Mar 28, 2018, 8:45 PM

#

i think you'd just call pixel on your fbuf instance:

pixel_value = fbuf.pixel(x,y)

#

@marble hornet are you wanting to do what's being shown in these guides?
https://learn.adafruit.com/micropython-displays-drawing-text
https://learn.adafruit.com/micropython-displays-drawing-shapes

marble hornet Mar 28, 2018, 8:47 PM

#

result:

#

>>> fbuf = framebuf.FrameBuffer(bytearray(10 * 100 * 2), 10, 100, framebuf.RGB56>>> fbuf.fill(0)
>>> fbuf.pixel(1,1)
0
>>>

#

@tidal kiln thanks!!

solar whale Mar 28, 2018, 8:49 PM

#

@tidal kiln for the erasers - I know there is a repo of them somewhere, but I cant find it. still looking

tidal kiln Mar 28, 2018, 8:50 PM

#

@solar whale ha! yah. so am i. been many weeks since i've needed to look for it. 😃

solar whale Mar 28, 2018, 8:51 PM

#

thats why I usually "roll my own"

tidal kiln Mar 28, 2018, 8:52 PM

#

fwiw, it's related to that memory leak post in the forums.

solar whale Mar 28, 2018, 8:53 PM

#

ah -- thats been interesting to follow.

tidal kiln Mar 28, 2018, 8:53 PM

#

feel free to jump back in. i'm not sure what's up. i can't recreate the issue. ran their sketch all night without issue.

solar whale Mar 28, 2018, 8:55 PM

#

wish I had something to offer... Sometimes I get memory allocation errors at startup that go away after a reboot, but not after a program has started running. I have not seen that. But I have not been using those drivers....

tidal kiln Mar 28, 2018, 8:57 PM

#

i'd think they've rebooted a few times by now. and additionally weird is that it seems to only be happening on one of their boards.

#

so just thinking a good next step might be to try starting clean - erase flash, etc.

solar whale Mar 28, 2018, 8:59 PM

#

I wonder if it is worth suggesting they try 3.0Alpha

tidal kiln Mar 28, 2018, 9:02 PM

#

maybe. but i was testing with 2.2.4 without issue.

solar whale Mar 28, 2018, 9:02 PM

#

true ...

#

I suppose they could try importing gc and then print out gc.mem_free() to see what is happening and possibly gc.collect() to see if that helps.

@marble hornet I would recommend against using nvm for memory you are going to change throughout the lifetime of a program. It'll wear the flash out

you can get the mpy versions from the releases page. you can also make them yourself using mpy-cross

is there a place that can strip that for you? and i can't unless i want to re-cahgne everything

ill check out mpy-cross

@marble hornet get mpy-cross here: https://github.com/adafruit/circuitpython/releases/latest

make sure you use the mpy-cross that matches your firmware version (2.2.4 uses mpy-cross 2...etc)

#

@marble hornet you could also download the mpy verison of the bundle:

and pull the mpy file(s) out of there

marble hornet Mar 29, 2018, 12:59 AM

how do i run my file through mpy-cross ??? it wont execute on mac

tidal kiln Mar 29, 2018, 1:00 AM

did you download mpy-cross-2.2.0-macos-high-sierra ?

tulip sleet Mar 29, 2018, 1:01 AM

#

run it in Terminal

#

./mpy-cross-2.2.0-macos-high-sierra foo.py creates foo.mpy

marble hornet Mar 29, 2018, 1:03 AM

#

what is ./? @tulip sleet

tidal kiln Mar 29, 2018, 1:04 AM

#

. = current dir

tulip sleet Mar 29, 2018, 1:04 AM

#

If foo is in your current directory, then ./foo will run it. Otherwise do /some/place/far/away/foo

#

you can't just say foo if foo is in the current directory, unless . is in your $PATH (which is not recommended for security reasons).

#

so ./foo means "yes, I really want to start at the current directory, which has foo in it, and run foo

marble hornet Mar 29, 2018, 1:07 AM

#

hmmm its saying permission denied

tulip sleet Mar 29, 2018, 1:08 AM

slender iron Mar 29, 2018, 1:28 AM

#

please be more specific

marble hornet Mar 29, 2018, 1:29 AM

#

i want to:

#

from adafruit_rgb_dispaly import colorst

#

colorst is an altered version of color565 in which is already in rgb.py

#

codes here:

#

    """Convert red, green and blue values (0-255) into a 16-bit 565 encoding.
        this makes it esier to sand colors"""
    return (r & 0xf8) << 8 | (g & 0xfc) << 3 | b >> 3


def colorst(r, g, b):
    """use this the same as solor565 but correct the bgr type of
        the st7735 displays"""
    return (b & 0xf8) << 8 | (g & 0xfc) << 3 | r >> 3```

slender iron Mar 29, 2018, 1:30 AM

#

try from adafruit_rgb_display.rgb import colorst

#

you need something after the . usually since adafruit_rgb_display is a package (aka folder)

marble hornet Mar 29, 2018, 1:31 AM

#

so i turned the rgb.py into an mpy and dragged that into to lib folder

slender iron Mar 29, 2018, 1:32 AM

#

if its just in lib then its just import rgb

marble hornet Mar 29, 2018, 1:32 AM

#

is anyone else getting weird results when deleting files and or corrupt files? Try to delete a file, it ends up being re-written with zero bytes.... windows strikes again? 😄

tulip sleet Mar 29, 2018, 3:07 AM

#

@raven canopy on Windows and Linux especially, it's important to do Eject or sync to get the filesystem data out. Deleting a file means changing the file metadata, and that info is delayed for a long time on Windows. Our recommended editors do a good job of making sure data is written out, but the filesystem operations one does in an Explorer Window or on the command line don't ensure immediate data write-out.

raven canopy Mar 29, 2018, 3:10 AM

#

thanks @tulip sleet. I'm usually pretty good about ejecting, and I haven't had any issues until yesterday. wanted to make sure it wasn't just a "me" thing. most likely is though... 🤦

#

that flash eraser works like a charm though. 😄

tulip sleet Mar 29, 2018, 3:11 AM

#

there could be bugs, so if you see this despite doing Eject, etc. then definitely report it. But if you delete a file and then hard-reset or power-cycle the board less than 60-90 seconds later, the filesystem metadata definitely could get hosed.

I want to add storage.format(...) so you can reformat from the repl. Just have to figure out how to specify which filesystem you want to format (could be CIRCUITPY or the SD card, if there is one).

raven canopy Mar 29, 2018, 3:12 AM

well, it maybe that not waiting. now that i'm a little deeper in the debug realm, i may be going a little too fast on resets.

tulip sleet Mar 29, 2018, 3:12 AM

#

is this M4 or M0?

raven canopy Mar 29, 2018, 3:12 AM

#

M0

tulip sleet Mar 29, 2018, 3:13 AM

#

The Metro M0 bootloader 1.26.0 and up makes it difficult to double-click to get to METROBOOT. We know what the issue is and need to figure out how to fix it. But the multiple double-clicking makes it really easy to damage the filesystem too.

#

if yours is 1.23.1 you're safe from that

raven canopy Mar 29, 2018, 3:16 AM

#

i think i'm safe. nary a Metro in the house. I will most likely get the M4 when it comes out though, since Feather will most likely lag behind. I'm an all Feather & Trinket operation for now. Got a CPX and an Itsy on the truck heading this way though.

[adafruit/circuitpython] New comment on issue #718: DHT22 driver not working under CP3\.0\-alpha

Looking into this real quick. Not to state the obvious, but the pulsein is failing to return any data. I turned off the raise RuntimeError in the driver, and enabled the print statement that was commented out. Here is the return message:

did not get a full return.  number returned was: 0

Will dig a little deeper.

@feral saffron your editor is not writing out the file completely fast enough. Read this page, and especially this section: https://learn.adafruit.com/welcome-to-circuitpython/creating-and-editing-code#1-use-an-editor-that-writes-out-the-file-completely-when-you-save-it

Next question - i am using a lsm303 (compass+accel) and i calibrated it to get the mins and maxs, but how do i use that in circuitpython, i dont see a way to set the mins and maxs in the api

pastel panther Mar 29, 2018, 4:15 AM

#

I'm not familiar with it but let me take a look

#

@umbral dagger can you be of service?

#

I'm not sure I understand the question. What do you mean by getting the mins and maxes? Is getting the minimum and maximum value a standard accellerometer thing?

feral saffron Mar 29, 2018, 4:18 AM

#

well, according to all the guides i'm reading, i need to calibrate it because i'm not getting correct output...

umbral dagger Mar 29, 2018, 4:18 AM

I didn’t go beyond the basics with it. I.e. just enough to do what I needed. Others cleaned it up. @idle owl maybe?

my magnetometer (compass) was only registering values between 100-140 degrees

feral saffron Mar 29, 2018, 4:19 AM

lol yeah, and sadly, i had the lsm9ds0 ... and had the same issues

#

was hoping the compass + accel would have better results

pastel panther Mar 29, 2018, 4:20 AM

#

is it just the magnetometer that is acting strangely?

#

I assume you're not sitting next to a MRI machine

#

Accel Minsx: -19.162 -19.162 -19.162
Accel Maxs: 19.162 19.162 19.162
Mags Mins: -3.727 -2.273 -2.245

@slender iron with regards to the purple pixel issue, I can no longer replicate on the current master. siddacious was still experiencing it on a trinket, so I'm not sure I would advocate closing it just yet.

is there an easy way to transfer files from a micro SD card in a feather M0 via USB? The feather is in a enclosure. i can plug in a usb cable but i have to open 4 screws to get the micro sd card out.

stuck elbow Mar 29, 2018, 11:54 AM

hmm, you could copy them to the internal flash, and then copy them via usb

#

it's a bit of work though, with remounting the flash in rw first and all that

timber vigil Mar 29, 2018, 11:58 AM

#

or would it be possible to write on files on the connected pc? i only want to copy text files and i could write a script that reads from the sd card and writes to the pc or something similar...

stuck elbow Mar 29, 2018, 11:59 AM

that would work too

actually, you might be able to do it with ampy

once you mount the sdcard

tulip sleet Mar 29, 2018, 3:47 PM

#

@feral saffron versions of mu for the past several months are fine with writing out files. The issue is using something else like an Explorer window for deleting files and then not ejecting.

#

@buoyant wigeon The specific problem with the Metro M0 has to do with some code we added just for that board to make SWD programming connecting work better. If there's a capacitor from RESET to ground, that's good. Usually there's also a resistor from RESET to the reset switch, which is grounded on the other side.

tidal kiln Mar 29, 2018, 4:12 PM

@split ocean looks like it might be a doc issue. not seeing anything in the code that actually supports that.

March 21 [2:11 AM] @tulip sleet : didn't know about tinycore - i'll keep that in mind for something

Dan: Jupiter Broadcasting's Linux Unplugged did a recent segment on 'Debian on the Fly' at
http://linuxunplugged.com/242
particularly at minutes 47 through 52 of this podcast (audio only) emission from them.
Quite similar ideas to those of TinyCore Linux (and DSL which came before it).

#

From what I can tell, this is about Slax (which I know zero about) at:
http://www.slax.org/en/
EDIT: Didn't see much in the way of documentation or support for slax; an article suggests it was fairly recently revived. I don't see a path towards using it similar to the one taken to install and make really good use of TinyCore.

"si prefixes" if you want to read more

i always have to stop for a bit on milli/micros though 😃

timber mango Mar 29, 2018, 11:55 PM

#

0.001 is one milliampere or one millisecond when expressed in whole units (amperes, seconds).

#

How many seconds are there in a year? If I tell you there are 3.155 x 10^7, you won't even try to remember it. On the other hand, who could forget that, to within half a percent, pi seconds is a nanocentury.
Tom Duff

#

0.001 second is one millisecond of time.
0.001 millisecond is one microsecond.
0.001 microsecond is one nanosecond.
1,000 nanoseconds are one microsecond.
1,000 microseconds are one millisecond.  I use this one a lot for precise timings.
1,000 milliseconds is one second.

#

A frequency of 1 GHz has individual cycles of 1 nanosecond duration. ;)

#

So a hundred megahertz oscilloscope needs to resolve to 10 ns on the horizontal timing.

#

https://richardsears.files.wordpress.com/2011/08/tek-561a-with-3a74.jpg

#

1000 MHz == 1 ns == 1 GHz
 100 MHz == 10 ns (0.01 uSec)
  10 MHz == 100 ns (0.1 uSec)
   5 MHz == 200 ns (0.2 uSec)
   1 MHz == 1000 ns (1 uSec)

0.2 uSec = time base (max) on that 561a oscope - a 5 MHz scope in that configuration (2B67 time base).
You obtain the extra resolution by pulling out on the time base knob, to magnify 5x (probably more optical of a zoom than further division of the timebase!)

In the Air Force I was pulled for instructor duty -- while still a student. I said no -- someone else wanted my orders, and policy was we could swap orders after graduation. @raven canopy
Here I get to expand a bit -- difficult to do so in person. It's my mishegoss to be here doing this. ;)

#

For some reason or another, the 60 Hz (in USA) line frequency for the power companies is extraordinarily accurate -- it is a time base. When digital LED (bedside) alarm clocks hit the market, they leveraged this fact (everything plugged directly in to 120 VAC in those days).

#

The clocks had a sampling circuit that disciplined their internal clock frequency, using the external, 60 cycle reference inherent in the very power supply itself.
I never did find out why and how the power company's time base was so accurate, but I'm quite sure it'd still be that way, today.
Aircraft generally use 400 Hz three-phase for onboard power requirements.

[adafruit/circuitpython] New comment on issue #726: Compiling and including libraries

Which neopixel library do you want? The one named neopixel is a Python-based library from https://github.com/adafruit/Adafruit_CircuitPython_NeoPixel. It's not built in; you'd get it from the bundle or otherwise have it on CIRCUITPY. The one named neopixel_write is a low-level library that is implemented in C and is built in.

@raven canopy glad a battery is on the way. If LiPo, do you have a charger? (Remember any Feather can do charging.)

@idle owl Doh! yeah one of the terminals are like hair thin. I put together a super basic main.py to light up a neo-strip but can't get the vib sensor to reliably trigger them.

[adafruit/circuitpython] New comment on issue #726: Compiling and including libraries

Thanks for responding! I hadn't realized there were two libraries.

I was hoping to get the neopixel library into the build.

Is neopixel really not built in? I just fully wiped my CPX and re-flashed it with the 2.2.4 version of circuit python that I downloaded from the releases page. And import neopixel does work. Maybe I'm confused about something here though.

Also, the Adafruit_CircuitPython_NeoPixel repo is linked inside the frozen/ directory of the 2.x branch of this...

idle owl Mar 30, 2018, 8:23 PM

#

@twin mica I thought that was me too. I went back to testing with a button thinking it was an issue with me.

#

I also have the medium vibe sensor, the light one or whatever it's called isn't in stock. Is that part of the issue?

#

Fast, that's it.

raven canopy Mar 30, 2018, 8:25 PM

#

the fast ones are pretty sensitive. but the "bounce" is also longer... like I said earlier, in my experience with them, it's a fine line...

errant grail Mar 30, 2018, 8:26 PM

#

@twin mica For some applications, to improve the vibration switch response, I've used two sensors mounted at different angles, wired in series to reduce sensitivity or parallel to increase sensitivity. Also, DigiKey has some sensors with more reliable wires.

idle owl Mar 30, 2018, 8:27 PM

#

@twin mica I can send you one of the pieces of code I have if you want to try that instead. But if it's not triggering, it's not triggering. That's easy to tell without the LEDs even.

[adafruit/circuitpython] New comment on issue #726: Compiling and including libraries

Ah, ok. It's not "built in" in the sense of frozen code, but it's included in the frozen modules for that particular board. The list of frozen modules to include is in atmel-samd/boards/circuitplayground_express/mpconfigboard.mk. If you haven't changed that, neopixel should be importable in your build.

How did you add your own extra frozen modules to your build? If it makes sense, point me to your github repo.

twin mica Mar 30, 2018, 8:30 PM

#

@idle owl yes please send! I'm have the fast and medium one here. They both work fine triggering a regular LED, like the one on-board the ItsyBitsy. It's triggering the NeoPixels thats iffy, sometimes it works, mostly doesn't 😃

Hey circuit python peeps... So I just completed my first ever circuit python script (... now that I think of it, my first *python script ever)

If you're feeling so inclined, I'd love a critique. It's going to drive lights that end up being embedded in a "cloud" structure (think Chinese paper lanterns with fibre fill "fluff" glued onto them) to look like a thunder cloud.

Ideally I'll want to attach either some bluefruit / bluetooth pieces to change color pallet / rate of "lightning strikes" and / or ambient color (it's a nightlight for my daughter's room) My other idea is to also hook up a raspberry pi and do either a private web service or some such thing to accomplish the same.

While it is traditional to have buttons on pins that are pulled up, and

connects them to VCC.

This patch makes the gamepad only change the pin's pull if it wasn't
already set when passed to the constructor, and also makes it consider
a button pressed when its value is the opposite of its pull.

off-topic for a sec: why can't there be more sub 5 1/4" phones besides the iphone SE?? i need a new phone; still running android 4.4.4 (droid mini).. 😦

need some assistance @idle owl ? or at minimum, venting/encouragement?

slender iron Apr 1, 2018, 4:20 PM

#

@raven canopy I think there are rumors of a new SE coming

idle owl Apr 1, 2018, 4:21 PM

#

@raven canopy Distinctly possible. However, I may have prematurely flipped that table. I think I at least figured out what the problem is. Which I'm pretty bloody proud of because this was a weird and entirely consistently inconsistent bug.

raven canopy Apr 1, 2018, 4:21 PM

#

@slender iron probably a 7-in-a-6-body? i still can't bring myself to crossover to iOS...

slender iron Apr 1, 2018, 4:22 PM

#

dunno the details

raven canopy Apr 1, 2018, 4:22 PM

#

@idle owl the table probably deserved it, either way. and this: "entirely consistently inconsistent bug." is PURE gold!

I like the term heisenbug

slender iron Apr 1, 2018, 4:22 PM

#

I like iOS. I've gotta replace the battery in phone phone and if that goes south I may need a new one

The bug that disappears when you try to observe it

cunning crypt Apr 1, 2018, 4:23 PM

#

I am totally appropriating the term Heisenbug

raven canopy Apr 1, 2018, 4:24 PM

#

it even applies to cars. "I swear it made that noise while i was driving to your shop"

hollow ingot Apr 1, 2018, 4:24 PM

#

Or if you want to go more "Walter White" heisenbug... https://s3.scoopwhoop.com/anj/WW/328000919.png

cunning crypt Apr 1, 2018, 4:24 PM

#

It applies to a LOT of things

[adafruit/circuitpython] New comment on issue #530: Deal with multiple boards showing same drive name on Mac OSX $and maybe other OS's$

Closing sounds good! I'll try and remember to highlight its addition in the next set of release notes. Thanks!

too bad Nest is already trademarked. that would make a great Feather Robot Nest... err, Robot FeatherNest; should escape trademark conflicts. ?

oh

😂

stuck elbow Apr 1, 2018, 7:38 PM

isn't nest dead?

🤷 i thought google bought them. or was it amazon? hard to tell these days. to the google machine!

stuck elbow Apr 1, 2018, 7:40 PM

#

they bought it and killed it

#

they really only buy companies to get the employees from them

raven canopy Apr 1, 2018, 7:43 PM

ahh. yeah, in February they announced they're rolling it into the hardware division alongside Google Home and Chromecast. effectively, "gone". 😄

does anyone know if Radomir Dopieralski is on discord? i'm trying to make changes to the rgb screen library, but i'm running into buffer errors. my change is to just change the numbers for coordinates being input

raven canopy Apr 1, 2018, 7:45 PM

#

hehe. @stuck elbow ^^^

marble hornet Apr 1, 2018, 7:47 PM

#

real!!

#

@stuck elbow could you help with that ^^^^

#

??

#

here are the rgb and st7735r libraries i've altered

📎 rgb.py

#

📎 st7735.py

#

📎 init__.py

#

i added an extra color function and needed to put that in init

marble hornet Apr 1, 2018, 8:10 PM

#

@timber mango no flash chip for cir-py?

timber mango Apr 1, 2018, 8:10 PM

#

its not running python

#

its a wing only!

marble hornet Apr 1, 2018, 8:11 PM

#

may I ask why it has a usb plug ? power?

timber mango Apr 1, 2018, 8:16 PM

#

debugging mostly 😃

#

we shall see. leeks are leeks!

marble hornet Apr 1, 2018, 8:27 PM

#

okay, thanks anyway! love your work!!

errant grail Apr 1, 2018, 8:32 PM

#

Dedicated USB for high-capacity battery charging? Wireless batt charging would be nice for an autonomous robot...

marble hornet Apr 1, 2018, 8:35 PM

#

yes, and yet the usb data pins are connected to the qfn chip. im guessing the qfn chip is the atsamd21 with seesaw code on it for the cap and analog pins

stuck elbow Apr 1, 2018, 8:41 PM

#

@marble hornet sorry, I'm here now

marble hornet Apr 1, 2018, 8:41 PM

#

@stuck elbow no prob

stuck elbow Apr 1, 2018, 8:41 PM

#

@marble hornet do you have the library's repository cloned?

marble hornet Apr 1, 2018, 8:42 PM

#

no, im doing it all locally

stuck elbow Apr 1, 2018, 8:43 PM

#

do you know how to clone it?

marble hornet Apr 1, 2018, 8:45 PM

#

Yes. I will. What are the advantages?

stuck elbow Apr 1, 2018, 8:59 PM

#

then you can commit your changes, push them, and submit a pull request for review and merging

marble hornet Apr 1, 2018, 9:09 PM

#

okay cloned, sorry was unpacking

#

@stuck elbow so i have two things i want to do i finished an rgb lib w/ text that is ready (as long as framebuf support is kept) and i'm working on rotation now which needs to be separate

stuck elbow Apr 1, 2018, 9:21 PM

#

ok

#

then let's make a branch with `git checkout -b rgb-text'

marble hornet Apr 1, 2018, 9:23 PM

#

should I navigate next to the adafruit....play ?

stuck elbow Apr 1, 2018, 9:23 PM

#

then copy your modified files over the files in the repository, and do 'git commit -a -m "Add text support"'

marble hornet Apr 1, 2018, 9:26 PM

#

okay

stuck elbow Apr 1, 2018, 9:32 PM

#

then on github you will need to fork the library repository

#

copy the url of the cloned repository

#

and do 'git push url-of-the-cloned-repo'

#

then again on github, you should see a button to make a pull request

marble hornet Apr 1, 2018, 9:33 PM

#

okay, working on it

stuck elbow Apr 1, 2018, 9:33 PM

#

let me know if anything doesn't work or you are not sure about anything

marble hornet Apr 1, 2018, 9:37 PM

#

okay commited

#

@stuck elbow so i added two files and they aren't showing up in the push

stuck elbow Apr 1, 2018, 9:44 PM

#

did you commit?

marble hornet Apr 1, 2018, 9:44 PM

#

output of me trying to commit just now:

#

    adafruit_rgb_display/rgb.mpy
    adafruit_rgb_display/rgb_text_.py```

#

suggestions

#

@stuck elbow

stuck elbow Apr 1, 2018, 9:46 PM

#

you don't want to add the rgb.mpy file

#

why the trailing _ in that rgb_text?

marble hornet Apr 1, 2018, 9:49 PM

#

@stuck elbow why not? , and I want people to be able to see the text inside the .mpy if they want to understand what it is doing like me.

#

the rgb.py alone won't run because it is too large

stuck elbow Apr 1, 2018, 9:56 PM

#

the libraries are getting compiles to .mpy automatically for releases

#

you don't commit the .mpy files, they are created for the release

marble hornet Apr 1, 2018, 9:56 PM

#

oh, okay

stuck elbow Apr 1, 2018, 9:57 PM

#

python has certain naming conventions, and that trailing underscore shouldn't be there

#

once you rename the file, you can add it with "git add rgb_text.py"

#

and then commit again

marble hornet Apr 1, 2018, 9:58 PM

#

now it isn't recognizing rgb.py
