How to Reverse Hebrew String in Python?

I'm trying to reverse Hebrew string in Python:

NAME_STRING = ''.join(reversed(NAME_STRING)) worked

yay do that then

tulip sleet May 28, 2019, 3:30 AM

#

I'm thinking we could take one of the free, say, Google, fonts, and trim out all but roman, accented roman, kana, kanji, hebrew, and korean

#

i.e. take out all the ideographs

meager fog May 28, 2019, 3:31 AM

#

yeah

#

we couldnt find one thats just that

#

would be a useful font, all the simplest characters only

tulip sleet May 28, 2019, 3:32 AM

#

me neither. the font melissa is using has a lot of empty glyphs, as opposed to missing glhyphs (which it also has). Maybe the empty ones are takign a lot of space

#

i dunno much about this, but was just looking at it in fontforge. This is interesting and could be a starting point for trimming a universal font: https://stackoverflow.com/questions/14557944/downsizing-an-otf-font-by-removing-glyphs

Saw in in the light docs for the CPX, for map_range but it isn't on my CPX.

no, it's a library written in Python that's in the bundle

rare geode May 28, 2019, 11:11 AM

we should probably move map_range elsewhere, because it's generally useful

I would use it in light mode anyway.

Right now colors are randomly generated with rgb values of between 100 and 255

can you tell whether you're in light or dark mode?

How many potential lines on a graph?

rare geode May 28, 2019, 3:56 PM

#

and should one be invisible to someone, it's just a matter of closing the plotter and reopening to get new ones

#

Unlimited theoretically

tulip sleet May 28, 2019, 3:57 PM

can you fetch the background color value and choose values to contrast with that?

scarlet maple May 28, 2019, 3:57 PM

How many potential lines realistically?

rare geode May 28, 2019, 3:57 PM

I'll have a look in atom docs to see what's possible 👍

Depends entirely on your system

I've got 100 lines on right now

#

this did make my laptop fans start to whir though

scarlet maple May 28, 2019, 4:00 PM

#

I've almost certainly missed some context. I've always had a relatively limited number of lines to consider if I had to deal with colorblind-accessible applications.

rare geode May 28, 2019, 4:01 PM

#

Ohh, I thought you were talking about the limits of just how many lines it could display, my bad

#

Well, there is no constant palette, colours are randomly generated with rgb between 100 and 200, this makes them stand out well from both light and dark themes

#

but I'm looking into finding the background color and changing that range dependent on the color behind the graph

I'm looking to make a GPS laptimer using pygamer (when it's available for order again). As a stop-gap, I've ordered an ItsyBitsy M4 to start developing. The system will use the GPS (ideally at 5 Hz), parse the NMEA sentences (hopefully filtering to just two per interval) and perform some maths to see if the last coords and previous coord intersect a virtual start/finish line, then do some very minimal screen updates if it intersects. Do we think that this can be performed OK on the ATSAMD51 using CircuitPython, or would I need to use Arduino C/C++ code?

scarlet maple May 28, 2019, 10:07 PM

#

I wouldn't think that doing a set of calculations a few times per second would be a big deal. The data transferred from the GPS device to the microcontroller per second isn't too high, either, is it?

rare geode May 28, 2019, 10:08 PM

#

5 Hz sounds reasonable yeah

errant jetty May 28, 2019, 10:22 PM

#

Cheers 😀

rare geode May 28, 2019, 10:23 PM

#

It really depends on how complex the maths is

#

I think that for testing for intersection you should be alright

scarlet maple May 28, 2019, 10:25 PM

#

Math: http://mathworld.wolfram.com/Line-LineIntersection.html

rare geode May 28, 2019, 10:26 PM

#

Yeah thought it would be line-line intersection

#

I worked with this equation when doing raycasting in python

#

It's not particularly intensive math

scarlet maple May 28, 2019, 10:26 PM

#

Though that might not quite be right in all cases. Might not consider what happens if the intersection point is outside the boundary of the four points given.

rare geode May 28, 2019, 10:43 PM

#

Hey @tulip sleet, since it was unclear about whether installing via git would activate the package automatically I've just copied the code from your repository over to the package, cheers for the recommendation 👍

I'm not sure where to look for information about sending text (as opposed to bmp's) to the screen.

trim elm May 28, 2019, 11:24 PM

#

@errant jetty Circuitpython would probably work great for that. For the timer itself, I'd recommend using time.monotinic instead of the time from the GPS as you won't have to worry about setting the time-zone, which can be kind of finnicky.

scarlet maple May 28, 2019, 11:27 PM

@spice tendon #help-with-circuitpython is more help-oriented than developer-oriented, but might not matter much.

i have a QUEST

gilded cradle May 28, 2019, 11:55 PM

#

Ok

#

What is the quest?

meager fog May 28, 2019, 11:57 PM

#

quest is - try to make a 'gif' that flips thru the different languages

#

and thats the thumbnail gif

#

try ezgif.com

#

you should be able to upload a bunch o images and make a 'flip' book, with 1 second per

#

you will get 5 GP and 3 EXP

Can't access it through my phone either. Same error

meager fog May 29, 2019, 12:20 AM

really

#

weird

#

ok

#

ill do the gif for ya

#

do you by chance hav eall the images in front of you

#

you can zip for me

#

if not i can extract em from the guide

gilded cradle May 29, 2019, 12:21 AM

#

Yes, I have them, but I'd like to really quick so the PyBadge doesn't appear to move around so much.

#

Should take like 10 minutes

meager fog May 29, 2019, 12:21 AM

First we need to add our new module. Look for a comment very similar to

// extra built in modules to add to the list of known ones

Add a line to the list immediately following it, similar to the rest. The difference in what you add will be that it mentions your new module:

extern const struct _mp_obj_module_t mymodule_module;

The second thing to do is add your module to the EXTRA_BUILTIN_MODULES macro, with a line like the others there:

{ MP_OBJ_NEW_QSTR(MP_QSTR_mymodule), (mp_obj_t)&mymodule_module }, \

Don't forget that reverse slash at the end of the line. ```

slender iron May 30, 2019, 5:30 PM

how does it not work?

marble hornet May 30, 2019, 5:31 PM

there is no EXTRA_BUILTIN_MODULESmacro in /ports/atmel-samd/mpconfigport.h

#

ah found it; building

#

build failed. think i have a typo. thank you @slender iron i'll work on a pr for the guide

#

so it's compiling and almost working: when i try to import mymodule i get an error saying it doesn't exist but i can reference it and see what's inside of it. like so: ```>>> import mymodule
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

@slender iron if i wanna subclass group in the cp source code should i just copy paste a version?

slender iron May 30, 2019, 6:35 PM

#

I don't know how to subclass between native objects

#

are you doing it for the poke module? I don't think it needs to be done in C

marble hornet May 30, 2019, 6:38 PM

#

yes it is, my though to doing it in c is that the events will be looked at every-time the display is refreshed

slender iron May 30, 2019, 6:39 PM

#

what do you mean by "looked at"?

marble hornet May 30, 2019, 6:44 PM

#

go through the events and manipulate the pointer location . that way the display refresh and pointer will always be synchronized and the python user doesn't need to call a process_events() function.

slender iron May 30, 2019, 6:45 PM

#

I don't think you'll want that natively done because the movement may need to be tweaked on a case-by-case basis

#

I wouldn't change the C until you know a specific thing that needs to be faster or data that needs to be exposed that isn't

marble hornet May 30, 2019, 6:47 PM

#

okay, i'll work on it script side for now 😃

slender iron May 30, 2019, 6:47 PM

#

kk, that'll be easier to iterate on too

#

event propagation and tab order can be very complicated. The HTML dom is the closest thing to what you are wanting I think

i wonder if we should actually expand the ignore-modules in .pylint.rc. not everything in Blinka will match the core. with the specific case of PWMOut, it looks like only the Coral and Giant Board will have PWMOut... RPi only has PulseIn. https://github.com/adafruit/Adafruit_Blinka/blob/master/src/pulseio.py

i'm sure this will be a larger part of the discussion when pylint version is bumped to current....

Hi, there is a strange code in the BME280 lib which is pointed by pylint:

        if var1 == 0:
            return 0
        if var1:
            pressure = 1048576.0 - adc
            pressure = ((pressure - var2 / 4096.0) * 6250.0) / var1
            var1 = self._pressure_calib[8] * pressure * pressure / 2147483648.0
            var2 = pressure * self._pressure_calib[7] / 32768.0
            pressure = pressure + (var1 + var2 + self._pressure_calib[6]) / 16.0

            pressure /= 100
            if pressure < _BME280_PRESSURE_MIN_HPA:
                return _BME280_PRESSURE_MIN_HPA
            if pressure > _BME280_PRESSURE_MAX_HPA:
                return _BME280_PRESSURE_MAX_HPA
            return pressure
        else:
            return _BME280_PRESSURE_MIN_HPA```

#

As var1 as been already tested to 0 above, I feel that the test if var1: is useless

#

Which make the final else: useless too (which is the line pointed by pylint)

tulip sleet May 31, 2019, 9:24 PM

#

@lofty nova Could you put all that in an issue for the library?

lofty nova May 31, 2019, 9:24 PM

#

I'm already working on an PR for that library

#

It's the pylint before submitting

#

😃

tulip sleet May 31, 2019, 9:25 PM

#

😃 OK, then I would say go ahead and fix it and note it in your PR.

lofty nova May 31, 2019, 9:25 PM

#

Thanks

#

Can you confirm my reading that if var1:is useless as it follows if var1 == 0:

simple pulsar May 31, 2019, 9:26 PM

#

You will get a change in behaviour

tulip sleet May 31, 2019, 9:26 PM

#

this code may have been translated from the corresponding Arduino library, so you might want to compare it with that and sees if there's actually some kind of error: https://github.com/adafruit/Adafruit_BME280_Library

lofty nova May 31, 2019, 9:26 PM

#

ok. I'll do

#

@simple pulsar, can you please leaborate ?

simple pulsar May 31, 2019, 9:26 PM

#

If _BME280_PRESSURE_MIN_HPA is not 0

#

Depending on how you fix it

tulip sleet May 31, 2019, 9:27 PM

#

Also there's this older Python library: https://github.com/adafruit/Adafruit_Python_BME280

#

which is deprecated

lofty nova May 31, 2019, 9:28 PM

#

As var1 has already been tested against 0, the if var1: should always be true ? SO never go to the else (as pointed by pylint). So we can remove 1 level of blockl

tulip sleet May 31, 2019, 9:28 PM

#

yes, can remove the if var1:

lofty nova May 31, 2019, 9:28 PM

#

👍

tulip sleet May 31, 2019, 9:28 PM

#

but it would be nice to know what's really right. I wonder if the test for zero was added as some kind of hack

simple pulsar May 31, 2019, 9:29 PM

#

One test is needed to avoid div by zero

lofty nova May 31, 2019, 9:32 PM

#

I'll check the history. The Arduino lib also has the test agaisnt 0 but not the other tests.

@lofty nova you could also catch the divide-by-zero instead of testing in advance, and throw some kind of error. The behavior of returning zero maybe be left over from the Arduino driver, and perhaps it would be better to actually throw an error. But I don't know the use cases. Also compare how the other similar drivers (BMP280, BME680, etc.) act.

Thanks @raven canopy , I'll do

#

It's already done. Have you done it ?

raven canopy Jun 1, 2019, 2:27 PM

#

sorry, yeah i did it.

#

question: have you experienced any occurrences of the calibration data resulting in var1 == 0?

lofty nova Jun 1, 2019, 2:29 PM

#

no, but I didn't let the chip run for long

#

As I explain in the commit, the only reason I see for var1 ending to 0 is that the reading of the calibration registers at start returns 0

#

var1 = (1.0 + var1 / 32768.0) * self._pressure_calib[0]

#

ok, not 100% true if var1 enters this formula with -32768.0

#

I have to double check again

#

But Bosch original C code has this test without any explaination to what could cause var1 to become 0

raven canopy Jun 1, 2019, 2:33 PM

#

yeah, i saw that. and reading through the datasheet, i can't really come across anything that explicitly states that * 0 should be guarded against. but, nothing works 100% correctly, 100% of the time.

lofty nova Jun 1, 2019, 2:35 PM

#

That's why I think only an hardware error could lead to this which would mean that the coefficients values couldn't/shouldn't be trusted. So better raise an exception which point that, than silently return 0 or a minimal valid pressure

raven canopy Jun 1, 2019, 2:43 PM

#

i tend to agree with that. since the calibration values are factory set, and static, i wonder if its better to just read them at init and store them... but that is separate from this PR

#

wait a sec though. that may already be happening. this file is loooonng. 😄

#

hehe. yep, it is.

raven canopy Jun 1, 2019, 3:09 PM

#

@lofty nova i approved, but didn't merge it yet. called in a second opinion... 😄

lofty nova Jun 1, 2019, 3:11 PM

#

I'm looking also into the issue reported by the guys who was claiming about a wrong formula to compute altitude. My thermodynamics are so faaaaar away ..

raven canopy Jun 1, 2019, 3:12 PM

#

sounds good. i never really found my thermodynamics, so i can kind of empathize. hehe

Hi, I'm flashing the Circuitpython bootloader and application to a SAMD21 based board, I'm using a jlink and gdb

#

How can I debug the CP code and not the bootloader code when the board is out of reset?

@granite crow have you read through this guide?

granite crow Jun 1, 2019, 5:00 PM

#

I haven't, but taking a quick look at it and I noticed a couple of things I was doing wrong

#

I was using arm-none-eabi-gdb instead of arm-none-eabi-gdb-py, I guess that's because the microbuffer stuff

#

And I was using target remote instead of extended remote

raven canopy Jun 1, 2019, 5:02 PM

#

well, use the GCC from the current build instructions. i think that guide is a little out of date on that.

#

the gcc-arm-embedded from the ppa repository works fine for me.

@granite crow when compiled with LTO, functions may have names like rgb_led_status_init.123.something or similar, so type the first part of the name, and the press the <tab> key to see what's available

granite crow Jun 1, 2019, 7:47 PM

It's not available, I guess it's being optimized because it's doing nothing when CP is compiled for my board

working with the new adafruit_featherwing and it seems odd to me that when I set the minitft.backlight property, the value I get back is 1-value_set

Hi, I try to play (from my MAC and with an android phone) with my FeathernRF52840 Express but I have a few problem...

#

First when copying the library package, there is not enough space (despite being an "Express") for all the file. My trick was to delete unecessary file during the copy... with "rm lib/._*"

#

If I do that, I don't need to choose what library to keep or not (I know most of those are not needed for my usecase, but it is sill an issue).

[adafruit/circuitpython] New comment on issue #1382: Add support for RGB LEDs as status pixels

Hi yall,

I have been working on this and feel like i'm almost there, i got a green blink when i plug in the test board but after that the LED stays off, i would love to get this working before sending a PR, mind taking a look at it when you got some time?

First i defined a new board, a copy of the Bast pro mini m0, and edited the mpconfigboard.h by adding the following symbols.

#define CP_RGB_STATUS_R (&pin_PA15)
#define CP_RGB_STATUS_G (&pin_PA23)
#define CP_RGB_STATUS_B (&pin_...

half sedge Jun 2, 2019, 11:21 PM

#

I believe the "block" size might be too big for those little *.mpy files. It could help to reduce that (if possible)... most of the problem is 0SX fault, but still, a popular OS.

#

Second: I am trying the color picker program from https://learn.adafruit.com/circuitpython-nrf52840/neopixel-color

Getting Started with CircuitPython and Bluetooth Low Energy

Quickly get started with an Adafruit nRF52840 board using these CircuitPython demos!

#

But the color always come back to green (after having displayed my color of choice). I don't see the line that turn it back to green, but it is not the line 23 "pixel.fill(packet.color)" as I added a print("Change Requested") line, and this only print when I pick, not when returning to green within the second.

tulip sleet Jun 2, 2019, 11:26 PM

#

@indigo yokelaude Here's some more information about avoiding creating useless files on Mac OS: https://learn.adafruit.com/welcome-to-circuitpython/troubleshooting#running-out-of-file-space-on-non-express-boards-20-39. The block size is 512 bytes on this filesystem. Will look at the color picker code and get back to you

half sedge Jun 2, 2019, 11:28 PM

#

Thanks @tulip sleet I knew about those trick because I have GemaM0 and TrinkedM0 board too... but your library size has exploded, and I did not expect that kind of problem with "Express" board.

#

Maybe it is time to split your library bundle in different parts.

tulip sleet Jun 2, 2019, 11:28 PM

#

We have stopped recommending that you copy the whole bundle any more. The guides have been revised to recommend that you copy only the libraries you need.

half sedge Jun 2, 2019, 11:29 PM

#

Like you could have all the graphic board related piece put together.

tulip sleet Jun 2, 2019, 11:29 PM

#

The bundle is now just a convenient download mechanism

half sedge Jun 2, 2019, 11:29 PM

#

Ok, well, I don't re-read the guide... I did what I used to do. 😉

#

One thing about the board right now, is that the "CHG" LED is blinking very quickly. This is unexpected and might be a hint that something wrong is going on.

tulip sleet Jun 2, 2019, 11:31 PM

#

The CHG light blinking is just the battery charge detection circuit turn on and off rapidly. It's distracting but it's innocuous.

#

I agree it's confusing.

half sedge Jun 2, 2019, 11:32 PM

#

To summarize what I did today: (1) Update the Bootloader (2) Put the latest Circuit Python (3) Put the lattest bundled (4) Copy an past Colorpick in code.py (5) Install Adafruit Android BT LE app (6) Try to change color.

tulip sleet Jun 2, 2019, 11:32 PM

#

I just tried the color picker and it's working for me.

half sedge Jun 2, 2019, 11:33 PM

#

Do not worry, I will try to troubleshoot that by putting more printf in the code. 😉

tulip sleet Jun 2, 2019, 11:33 PM

#

There is a bug in the BLE code that causes the program to throw an exception with the latest CPy. I only discovered this a day or two ago, and am planning on fixing.

#

if you want to try my current code, get the library from https://github.com/dhalbert/Adafruit_CircuitPython_BLE, branch python-advertisement-data, and I can give you a test .uf2 for CPy also

half sedge Jun 2, 2019, 11:34 PM

#

Yeah maybe this is early to try BLE with Circuit Python... but I have that board since so long, and not being able to use it yet, so I gave it a try.

tulip sleet Jun 2, 2019, 11:35 PM

#

There should be a beta 4.1 with BLE improvements and fixed libraries in relatively short order.

half sedge Jun 2, 2019, 11:35 PM

Hi, thank you for your perfect analysis, I have the same problem in a different context, and I spent days to find a solution. I'm not sure to find one now, but I know what to try.
If my case can help to motivate MS to fix this trouble: we use a custom ioT, which has 1MB of flash with USB port. It is used to configurate it, and to copy some data.

@old smelt you have to replace the ESP32 firmware and it is not as reliable as the ESP32SPI library. It works, but it is no longer supported

old smelt Jun 3, 2019, 4:40 PM

#

Ok. As it turns out, when Amazon delivered what I expected to be my Argon a few minutes ago, this was inside the envelope instead.

It's eye-catching and everything. But I don't see a port for it on GitHub. So, I'll need to wait a while longer. 😉

solar whale Jun 3, 2019, 4:41 PM

#

Hmm-- interesting substition 😉

#

Unless you really have to use the Argon, I would recommend using an ESP32-Airlift with an M4 or nrf52840 board and the ESP32SPI library.

old smelt Jun 3, 2019, 4:43 PM

#

Ok - I'll check it out. Thanks! I want the Argon for other purposes, as well, but maybe I'll try the other boards for CP.

@prime flower on PWMOut exceptions, shouldn't the _sets also check? might be better to have an _is_deinited() and just call them in _write_pin_attr and _read_pin_attr?

I think returning right before it starts doing os operations is a good move @raven canopy

raven canopy Jun 3, 2019, 8:51 PM

yeah. it'll be the first call. i am expecting the exception to get chained in the _get calls though. fairly certain it will show up as while handling the above exception, the following exception occurred, and print both ValueErrors. let me ruminate a few minutes. 😄

How does sample playing work in CircuitPython when the wav file is larger than memory?

meager fog Jun 3, 2019, 10:50 PM

#

it loads it on the fly

#

thats why QSPI is best, SD is slower

simple pulsar Jun 3, 2019, 10:51 PM

#

I suppose I can try this but can I play at 100kHz like that? I'm just playing around with some non audio samples.

#

Perhaps I'm limited by the frequencies a wav can support too

meager fog Jun 3, 2019, 10:53 PM

#

its likely limited to 44.1khz

simple pulsar Jun 3, 2019, 10:59 PM

wikipedia suggests the sample rate in wave is simply a 32 bit unsigned. I'll give it a go tomorrow and see what it does.

our decoder logic may not permit it

A 96kHz wav loads in but show up as 30464 which happens to be 96000-65536 and it sounds like it really does playback at 30464 sample per sec

#

8bit 64kHz wav plays ok a CPX , it looks like the first limitation is use of a 16bit unsigned somewhere to represent sample_rate

I wanted to experiement with some non audio playback and made some 8bit wavs to check playback. 64000 is ok but this one plays slowly and inspecting sample_rate shows why:

>>> wave_file = open("Evillaugh.96000.8bit.mono.wav", "rb")

>>> wave.sample_rate
30464

tulip sleet Jun 4, 2019, 7:12 PM

#

@crimson ferry it is complicated for SAMD chips. Each pin supports zero, one or two timers, and various channels on those timers. It is not a crossbar. So using one pin may block another pin from using the same timer, if they share that timer.

#

also there are two kinds of timers, one basic and one more sophisticated

I checked other uses of sample_rate in other audio native classes, and they are uint32. The WAV file header itself uses 4 bytes for sample rate. So this looks safe and consistent.

@slender iron FYI I'm debugging an issue @tough flax found reading touch inputs in a pyportal program. Just a heads up that if this looks fixable easily, we should include it in in the next bugfix release. NO issue yet, still characterizing it.

@dhalbert Hi, i was planning to check what is the maximum sample rate allowed for wav files. But as you say it seems its safe to merge.

For reference:

Appears to me it's because sample_rate is an uint16_t in the audioio_wavefile_obj_t type.

While the parsed sample_rate of the wave header format is uint32_t:

I think there is already a paragraph that says that when a main.py ends, it give back control to the REPL in a fresh new VM instance that do not inherit of any context from main.py. So may be your FAQ item should point to that paragraph for more explanation ?

#

May be not in that guide. May be in readthedocs. I'm searching ....

#

In https://circuitpython.readthedocs.io/en/latest/README.html, "Behavior" says:
"""code.py (or main.py) is run after every reload until it finishes or is interrupted. After it is done running, the vm and hardware is reinitialized. This means you cannot read state from code.py in the REPL anymore."""

#

It is in the difference-with-micropython section. So may be not obvious for beginenrs

tidal kiln Jun 5, 2019, 7:01 PM

#

ah. good find.

lofty nova Jun 5, 2019, 7:03 PM

#

Which remind me a question I wanted to ask to the team : Does code.py inherit of anything from boot.py ?
If I am correct, in micropython, anything imported or created in boot.py is available to the code in main.py.
Is that or not the case with CircuitPython ?

tidal kiln Jun 5, 2019, 7:08 PM

#

not sure, so tried it...
boot.py

foo = 23

code.py

print(foo)

thanks @tidal kiln . I should have tried it myself :)
So definitively no inheritance.
Except for the filesystem mount as it is in boot.py that we can remount the file system in read-write.
But nothing from the VM

i could be doing it wrong though 😃

Ok, so just for you to gain trust in yourself, I did it and got the same result 😄

And also double checked in micropython and main.py inherit of the foo value set in boot.py as well as the REPL inherit of what main.py left

as discussed before (@timber mango) I would like to do my own board (in a special form factor)
the decision is now that it will have the same "core" (MCU) than feather M4 express .
@tulip sleet mentioned that I have to use my own USB VID/PID then.
Question 1: do I have to use one set of USB VID/PID for the UF2 Bootloader and another(!) set of USB VID/PID for the Serial (CDC) of the running firmware ?

#

Question 2: if I do that, does the Win7 drivers* from adafruit stop to work then (cause of the different USB VID/PID) ?
*(https://github.com/adafruit/Adafruit_Windows_Drivers/releases/latest)

quasi fjord Jun 6, 2019, 6:32 AM

#

q1) I suspect it would confuse the hell out of Windows to have the same ID report different descriptors at "random". q2) Yup. If it's just for your use you can force the Win7 drivers on your VID/PID. Or you could just forget about Windows 7

I was thinking about this a bit more. This can be picked up by the compiler but the warning isn't commonly enabled perhaps because of the traditional habits of the typical C programmer. gcc's -Wall and -Wextra do not enable this warning but -Wconversion does, an example:

$ cat -n integer-assignment-size.c | sed -n '12,15p; 21,22p'
    12    unsigned int a;
    13    uint32_t b;
    14    unsigned short c;
    15    uint16_t d;
    21    c = a;
    22    d = (uint16_t)b...

It sounds like the output is being reset even though never reset is used. I'd suggest breaking on common_hal_pulseio_pwmout_set_duty_cycle to track that the correct values make it to the pwmout class. If that's true, then I'd make sure the TC and pins aren't accidentally reset.

@slender iron I added the displays objects to the root pointers, but discovered that since they are not on the heap, they will not be scanned as root pointers. They need to outlive the heap betweeen VM instantiations but still be on the heap from the point of view of gc. What do you think is the best way to accomplish this? Perhaps I need to copy the contents and stash them away between VMs. Or is there some storage that looks like it's part of the heap but isn't reset between VMs?

#

Are there other objects that outlive the heap but are still Python objects, and need to be root pointers?

[adafruit/circuitpython] Pull request opened: #1928 Include display objects in gc

The Group object in Display was not being marked during gc. Because the display objects are not on the heap, they can't be added to the root pointer list. So gc them explicitly.

Also:

Added a gc_collect_ptr() routine to gc a single pointer, for convenience.
Fixed some #ifdefs that should have been #ifs.
Added some missing #ifs in nrf port.
Removed redundant #if guard in reset_displays().
Removed a SAMD21 platform setting from some doc.

In the long ru...

I thought of calling gc_mark directly, but thought someday we might want gc_collect_ptr() to do something else before it calls gc_mark(). Having a routine called gc_mark() is really clear about what it does. It marks and only marks.

@tulip sleet For the mpy change you mentioned, two questions 1) can Circuit/Micropython read both the old and new verison mpy files and 2) do the mpy files have the mpy version recorded in the them?

tulip sleet Jun 6, 2019, 10:35 PM

they do have the version number inside, to check compatibility. can't read both; there's no real reason to provide backward compatibility, cause you can just recompile

It's convenient to support a few versions but I can see with the size constraints why they this doesn't make sense here.
