this will obviously add a bunch of execution time for short intervals, which is why I'm not worried about those. but for big ones like 1000us I'd expect it to be more on target
- 1us -> 14.7us
- 10 -> 30.4
- 100 -> 188
- 1000 -> 1769
tulip sleet
well, when you enable interrupts, if there's a pending interrupt (like a USB tick), then a lot can happen then, and also, the background tasks are running, and they use up a lot of time (which we need to fix)
ionic elk
oh that's true.
tulip sleet
I'm suggesting you test this at the C level, by setting some volatiles that store systick or cyccnt and then just setting some breakpoints or something, or adding print statements temporarily
ionic elk
microcontroller.disable_interrupts()
pin.value = True
microcontroller.delay_us(1000)
pin.value = False
microcontroller.enable_interrupts()
still evaluates to 1765
but I'll test it in c
tulip sleet
it's still going to call the background task checker RUN_BACKGROUND_TASKS between statements
ionic elk
oh between all micropython instructions you mean
simple pulsar
@tulip sleet FYI, wrt serial blocking on bluefruit in arduino world, CircuitPython doesn't seem to suffer based on some testing with print: https://github.com/adafruit/Adafruit_nRF52_Arduino/issues/375#issuecomment-551166774
tulip sleet
right
ionic elk
Still, why would 100 -> 188 in that case? if it's additive, that doesn't really make sense as an output
tulip sleet
RUN_BACKGROUND_TASKS gets called at various times
it might take 88us to actually get to flipping the pin value
the systick timer interrupt runs at 1ms intervals and also runs background tasks, I think
i'm just saying test it in a way that cuts out all other potential overhead
ionic elk
The systick one makes the most sense to me. I don't think it can be additive pin flip execution delay if the numbers are 10 -> 30.4, 100 -> 188, 1000 -> 1769, that doesn't imply a consistent delay. But that means I'll have to disable systick
even if I do it in c
In any case this is all on my Atmel control, maybe I'll run it on stm32 and not get it
tulip sleet
@simple pulsar hmm, that's interesting
I'm just saying add stores of systick into before and after voltatiles at the beginning and end of the delay routine. That and turning off interrupts should get you an accurate idea of the delay
it may well be not that accurate, but I think Scott did test it. I thought we were using a similar technique in neopixel_write, which requires accurate timing

I've a question for core circuitpython codebase. When creating a file on filesystem what API to use to write data into that file?
f_write() ?
simple pulsar
@obsidian compass I don't know if it's the best example but I know the PyPortal code writes a file to either the (previously write enabled) flash or the SD card: https://github.com/adafruit/Adafruit_CircuitPython_PyPortal/blob/master/adafruit_pyportal.py#L843 - there seem to be some precautions on write size which don't feel like they belong in application code, though
@obsidian compass It's also described in a guide with a dedicated page on it: https://learn.adafruit.com/circuitpython-essentials/circuitpython-storage
obsidian compass
@simple pulsar Thanks alot for pointers, I will look into it 🙂
For now when using f_write to write ASCII strings the result shows HEX in file, any idea?
obsidian compass
@meager fog I am actually looking for making files in core code like when building circuitpython file system and that filesystem has a file with some strings
so when we build and flash the .uf2 it has that file

ok great - a lot of people are on break this week

i also know micropython creates files with stuff in them
you can look upstream

@obsidian compass a good example is how we write to boot_out.txt in main.c. You could create code.py in a similar way

Mine is a bit - modified from the original guide -- I'll go back to the original and implement the changes - I was just going to try the new CPB rover @split ocean put in the learning guides -- it will need similar changes.
tulip sleet
oh, i thought you meant JP's guide, but yes, the other will be good too
solar whale
the one I am using is on a feather nrf52840 and I have added some neopixels

I had done this one: https://learn.adafruit.com/circuitpython-ble-crickit-rover and the new one with Circuit Playground Bluefruit is in moderation, using this code: https://github.com/adafruit/Adafruit_Learning_System_Guides/tree/master/Turtle_BLE_CPB_Crickit_Rover
solar whale
@split ocean yes -- Those were the ones I was working with and now adapting to the new bleio/BLE library. they no longer will work with the current master and BLE library.
I think the only change I made to the original ble_cricket rover was in the number of neopixels -- If you want to see -- here is the new version .
I'll try the same with your CPB version -- just need to swap boards around to try it!
solar whale
@split ocean here is a modified version of the turtle_ble rover that seems to work
solar whale
@split ocean FYI -- for the motors I am using I had to increase the speed settings .25 just caused then to whine -- I used 1.0 for FWD -.7 for REV ....
split ocean
this is for the CPB version? I was running them at 0.25 on the lastest version. This is heavily battery dependent, BTW.
big current draw at the lower speeds.
solar whale
yes for the CPB, running on 5V supply for now -- not sure where I got these motors either -- I'll experiment with other motors. Just want to let you know incase it comes up.
split ocean
thanks, great point, I'll add a note in the guide that tweaking motor speeds in the code may be required.

ah nice! I think the CPB version of the code may win for precision control, but the Feather one on raw, reckless speed!

Has anyone looked at the performance of bluetooth data transfers on the Circuit Playground Bluefruit with CircuitPython? I thought I'd check the latency and it appears to be around 43ms RTT for an "echoed" ColorPacket() from one CPB to another. I don't need a lower number I was just measuring it. That number does include one packet parse operation at the moment.

@tulip sleet for CTS, in the older BLE lib and the new one (in standard/standard.py) there is a property struct_time. Did it ever get tested? It looks like it is missing the "year" argument and time.struct_time() wants a (9-tuple) input -- I think here should be two "-1" at the end for Day of Year and DST. I was getting errors about the 9 arguments until I changed it (added year and an additional -1 . I modified standard.py with these changes and fixed the imports (I think)... still having other issues but just wanted to check if I was missing something regarding this property since it came from the older code but I'm not sure it ever got used.
tulip sleet
@solar whale I only tested it in the REPL, and it's possible I wasn't very thorough
solar whale
was "year" intentionally omitted?
@tulip sleet don't spend any time on this -- I'm sure you have other priorities -- I was just curious -- happy to keep hacking....

@tulip sleet Thanks, Adafruit and it's staff ROCK
tulip sleet
@dense pike OK, the answer is that if you just write any old text back from the uart_server, it will appear in the text box on that page. All that box is doing is showing characters sent back from the BLE peripheral
dense pike
@tulip sleet what would be the command to do that?
tulip sleet
@dense pike like
uart_server.write("Thank you for pressing that button\n")
actually maybe need
uart_server.write(b"Thank you for pressing that button\n")
since you need to send bytes, not a string, but a regular string might work. Don't have time to try it at the moment

Ok, downloaded file again and reloaded lib files. All is working! 🙂 thanks

it's unusual to have truncated files when copying on MacOS. It's pretty good about writing files to the device as soon as possible (Windows and Linux can not actually write the data for 10's of seconds, on those boxes it's recommended to do sync or the equivalent). But the nRF52840 flash is pretty slow. If you happened to start a copy and then unplugged or reset a little too quickly, you might have interrupted the copying. On the other hand, this is extremely unusual, so nothing really to wrory about

@tulip sleet Wrong channel. Oops.
I added the if not data: check, currently it's a RuntimeError - not sure if that's the best choice. The issue was that it was failing with TypeError: object of type 'NoneType' has no len() for obvious reasons when there was no data sent, but that's super cryptic if you're not looking at the driver. The wiring is the issue when that error is thrown.
@property
def temperature(self):
"""Return the on-chip temperature, in Celsius"""
self._uart.write(bytes([0x50]))
data = self._uart.read(1) # 1 byte return for temp
if not data:
raise RuntimeError("Sensor not found. Check your wiring!")
if len(data) != 1:
raise RuntimeError("Did not receive temperature response")
temp = data[0] - 45
return temp
also now wondering if that should be an elif on the second one now.
tulip sleet
@idle owl if the q is whether RuntimeError is a good choice, yes, I think so: indicates some problem beyond the program's control
tulip sleet
don't need elif really because the raise exits the routine
idle owl
Ok

like, it would make sense to add a blank line after the raise, because that is a self-contained "paragraph" that validates data. So you can see elif is not part of that

we did look at flake8 a bit, but pylint seemed more comprehensive. but if you have a better auto-review workflow, that would be great to know

flake8 is style check, pylint is borderline static analysis.
so you do give up some of that.
In projects past, we've made up for that by enforcing really high testing standards (100% coverage, etc.)

our testing story is not good, because testing physical stuff is hard; we had a Linux box with boards connected via USB to do some testing ("rosie"), but it was not a reliable setup
ivory yew
yeah testing is hard.
So I'm writing the software library for Sol
and I want it to be 100% tested
So mostly a lot of mocks.
I don't love that.
It'd be cool to have proper stubs (Blinka but for testing) but that isn't perfect, either.
but even those things improve your confidence interval.
SmolMIDI has 100% test coverage and just uses a small Stub for usbmidi.PortIn: https://github.com/theacodes/Winterbloom_SmolMIDI/blob/master/tests/test_winterbloom_smolmidi.py#L9-L26. That plus some testing to validate the behavior on real hardware gives me a fairly good amount of confidence.
But I missed the buffer overflow thing by not having real hardware to test with.
tulip sleet
@raven canopy is working on a testing framework which I don't understand yet
ivory yew
or rather, I would have missed the buffer overflow if I wasn't testing with real hardware.
all this is to say
A project's health is determined by a lot of factors. Style, static analysis, various forms of testing, etc.
Using pylint to help hold the health up to makeup for testing is a good idea.
I'd love to see us use mypy or pytype. but that'd require a lot of work for us to create type files for the native types.
raven canopy
@tulip sleet once I can understand my creation, I'll be able to explain it better. 🤣

Does CP for the Particle Argon support WiFi functionality?

@old smelt Not directly -- you can reprogram the ESP32 on hte argon to act as a wifi co-processor (but only with the limited AT command set -- not the preferred SPI firmware) see this guide https://learn.adafruit.com/adding-a-wifi-co-processor-to-circuitpython-esp8266-esp32/overview

@ionic elk hihi whats next for stm32 for uuu
ionic elk
@meager fog Re-forking to fix a weird merge issue, then Neopixel, then new board support, then probably clock revamps?
anything you want to push up?
meager fog
nope thats good, id fix the clock before new board support
just cause like, thats a core bug
and people will appreciate 2x speed up
meager fog
@ionic elk ill test neopixel when you are ready for me to
ionic elk
@meager fog well, it isn't hurting anything atm, and could impact other boards
tulip sleet
@meager fog we have the beginnings of this for SAMD, but not to actualy change the clock speed: https://circuitpython.readthedocs.io/en/latest/ports/atmel-samd/bindings/samd/Clock.html
ionic elk
because of min speed increases
meager fog
@ionic elk yeah but if fixing the clock breaks something, we need to find out what pretty fast
ionic elk
I'll bump up the speed and see what happens then
meager fog
@ionic elk you should be able to see the i2c clock speed
and SPI clock speed and UART speed
e.g. 100khz for i2c is defaulkt
ionic elk
I don't expect it to actually break modules in terms of functionality. My primary concern is that the divisor on SPI doesn't go high enough to guarantee really low clock speeds when the system clock is really high, so it might make some external boards unusable.
But I can see how having fast speeds and simply fixing the problems is a better approach. I'll switch it over and test things out before moving to neopixel.
meager fog
@ionic elk im not too worried about that
SPI is like, 1MHz + in general
and like ya said, lets break and fix now - cause there's only going to be more protocols/confusion later 🙂
might even want to do it before neopixel since thats is very timining specific

FT232h is great but a little $
MCP2221 is a usb to i2c/gpio/pwm/adc for $1.50
there's a devboard on DK for a few bucks
and a python library by some person in japan
idle owl
@tidal kiln Thanks for looking into that.
tidal kiln
yah. totes. looks fun.
meager fog
ok i also grabbed some of these
i was thinking it would be cute to have a USBC-MCP2221A-STEMMA adapter for like $5
so you can quickly chain connect various i2c device
i noticed that this one does not do SPI at any reasonable speed so FYI!
however it does do DAC/ADC/PWM so it would require more shimming for Blinka support on those
another fun-fact - this chip comes in DIP!
tidal kiln
DAC/ADC/PWM would be great
def looks interesting enough to play with
is that dev breakout good enough for testing?
meager fog
yes totally
if you say it works somewhat, ill design our own breakout
that is nicer/more useful

marble hornet
@slender iron thoughts on displayio on nrf840 w/ parallel st7789s
marble hornet
possible?
slender iron
@marble hornet you mean 8-bit parallel buses or multiple displays?
marble hornet
8-bit busses
marble hornet
the docs say that parallel displays have to have the pins in order. just to be sure i am reading it correctly that means they all need to be in the same port and there have to be at least 7 more bits in the msb direction? or is it lsb?
slender iron
right. the cpu needs to be able to write a byte directly to the pins
arm is little endian so I believe its pin 0 is bit 0
marble hornet
cool! does it have to divided along one of the bytes along a port word? or could it start at bit 3?
and an aside: (writing some atmel c for my 231 class has been so cool and really given a respect for the c work all of you do (and I still probably don't see the full picture)). awesome work!

hey all!
i'd like to ask about creating modules with c for micropython
ideally i'd love to mix between arduino code and micropython code, but i know that's theoretically not possible (they have different backends) but might actually be possible (most arduino implementations are wrappers for platform-specific function sets)
but mostly, i'd like to know if there are examples on how to access things like i2c from the c side
onyx hinge
A side effect of the non-finishing actions runs seems to be that the artifacts don't become available either. 😦
@tulip sleet just noticed in the GNU Tools for Arm Embedded Processors 9-2019q4-major Release notes:
manic glacierBOT
Testing performed: built locally for metro m4 express, connected from unicode-capable terminal program, provoked an error:
There are still unavailable characters in the on-board font. I don't know if this should be enough to prevent inclusion of this patch.
main meteor
@mystic shell I think what you describe is fairly straightforward. You should be able to find C I2C code easily enough (it's not a difficult protocol, you can bit-bang it fairly easily if need be). However, I don't have any examples to hand.
onyx hinge
In CircuitPython, the builtin displayio module is an example of using circuitpython's I2C from C code. However, that'll be different than in Micropython.
tulip sleet
@onyx hinge A side effect of the non-finishing actions runs seems to be that the artifacts don't become available either. 😦 Yes, we've been relying on this, and now have to pass .uf2's around for testing.

Hey... so I'm sooooo close to getting this radio module working (as in "make it work, make it work correctly, make it work correctly with tests and docs").
I'm still at the "make it work" stage. I can broadcast messages. That all works fine. I can also see incoming entries when I don't specify the AdafruitRadio subclass of Advertisement -- I can see the messages broadcast from the other device to the receiving device. However, when I pass in the AdafruitRadio advertising class into the start_scan method on BLERadio it doesn't work. It appears the start_scan method on the instance's _bleio.adapter doesn't like it when there are prefixes from my new AdafruitRadio class.
I get the feeling I'm missing something here... 😉
Any hints...?
Both the sending and receiving devices report that the message is: b'\x1e\xff"\x08\x1a\x01\x00Hello0\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00'

huh for some reason I thought the bluefruit would be faster than the metro m4 express but it's not in my test

@onyx hinge I wouldn't think so, I think the Metro is a beefier version of the M4 chip because there's room for it on the board. But I'm also guessing here.

OK, now that I check it's 120MHz for the Metro and 64MHz for the CPB

ionic elk
@tulip sleet can I bother you with a C question or are you setting up for the meeting
onyx hinge
@ionic elk is it worth just asking the whole channel?
idle owl
@ionic elk Currently in a meeting.
ionic elk
@onyx hinge if you're down! I'm trying to figure out the following snippet of code:
#ifdef MICROPY_HW_NEOPIXEL
const mcu_pin_obj_t* neopix = MICROPY_HW_NEOPIXEL;
//if (pin_port == MICROPY_HW_NEOPIXEL->port && pin_number == MICROPY_HW_NEOPIXEL->number) {
if (pin_port == neopix->port && pin_number == neopix->number) {
neopixel_in_use = false;
rgb_led_status_init();
return;
}
#endif
the commented line throws a compiler error: invalid type argument of '->'
which is weird because a) this works in every other port and b) even the debugger and print messages show that the neopix variable and the macro are identical
onyx hinge
@ionic elk this is in stm32 I assume, with code shuffled over from samd?
can you show the line which #defines MICROPY_HW_NEOPIXEL?
ionic elk
I'm running into it in the stm32 port, it's not strictly based off either other implementation, it's just trying to use a macro like they do
#define MICROPY_HW_NEOPIXEL &pin_PC00, which is the same as other ports
onyx hinge
ports/atmel-samd/boards/winterbloom_sol/mpconfigboard.h:#define MICROPY_HW_NEOPIXEL (&pin_PB03)
can you try adding the parens as in this random case?
ionic elk
is it the parenthesis?
onyx hinge
I am betting that &a->b is &(a->b), not (&a)->b due to operator precedence
ionic elk
yep that was it, thanks!
onyx hinge
you're welcome
ionic elk
yeah I should have spotted that. Good to remember for preprocessor use
onyx hinge
so I'd say general C advice is that a #define should be parenthesized unless there's a specific reason it shouldn't
It's easier to see when it's #define FOUR 2+2
as 2*FOUR is now 6, not 8
ionic elk
yeah it's a good point, I was probably thrown off by how many stm32 functions take &a->b as an input, but they actually want the &(a->b).
onyx hinge

@tulip sleet "double width" refers to how things are rendered in fixed-width terminals, not to in memory representation

@onyx hinge I didn't mean to connect double-width with utf16, but I have a vague memory that we didn't have utf16 support which we needed for the CJK support, (or it would be very helpful for space reasons). But I think the main thing was lack of Korean glyphs even for the syllabic alphabet
we don't need that many glyphs for Korean, but we didn't have the Korean glyphs merged into the terminal font

I worked at The Guardian when the Snowden revelations were in full swing. When MI5 came to the offices to destroy the hardware (laptops) containing the data, they made especially sure to destroy the chips related to the keyboard (buffers?).
turbid radish
Does that combo even work??

@turbid radish my Model M has a PS/2 keyboard connector which still works on my newest desktop, happily

@turbid radish Highly doubt it

Dvorak is a pretty awesome composer. Hated tuba players tho... I only get 14 notes in the whole of Symphony No.9 😉

@plucky flint - interesting......

The journalists took videos of the MI5 folks destroying things, and there was a LOT of speculation about why they destroyed such-and-such a bit and not some other bit.

@inland tusk, is it "sunbox" synth? not sure of spelling

I’d love ideas on make the physical “bars” of the bar chart.

@tulip sleet were you saying there is going to be a CP 5.0.0 alpha 0? That will have the BLE api changes coming soon?
tulip sleet
beta.0
swift arrow
ahhhhhhhhhhh
I was trying to figure out how we were going from Alpha 5 to 0 🙂
makes sense.
really looking forward to that and helping to beat on it once it drops

@ionic elk Limor requests: Could you do urandom first, and then add all those boards?
tulip sleet
@onyx hinge You could do some quick sample builds and see if gcc9 update gives any significant space improvement on M0 builds. Otherwise we can hold off for a while.
onyx hinge
@danh ok I'll look at size and performance
solar whale
@plucky flint fired up the ble radio example on a pair of CPB -- works great!!
meager fog
@onyx hinge ok sounds good, once those two are PR'd (or abandoned :), ping me if you have more time for the week and we'll figure out whats next!
onyx hinge
Will do!
meager fog
@ionic elk ok your next todo after you're happy with neopixel is urandom
the rest are more structural, you'll want to wait till scott is back around
solar whale
@plucky flint even got a "3-way" going with 2 CPBs and an nrf52840_express -- no problems with multiple senders/receivers -- posted example to your repo
solar whale
hmm -- haven't tried moving about much -- I'll try now
several meters works fine -- at about 10m - the receive rate seems to drop off -- but still receives.
can't get much farther -- my house is not that big
that was transmitting from nrf52840 express -- receiving on CPB
over 10 m -- get nothing
very rough estimates - and walls
I can try to be more systematic later - or tomorrow,
tulip sleet
@ionic elk I can send you a movie. I'm having trouble getting the board into DFU mode. It worked once, and I loaded it, but now it's flaking out again
ionic elk
I'm not super up to date on DFU stuff! I've been meaning to spend some time on it and I'm ready to do that whenever, but I've always simply been a heavy STLink user
tulip sleet
@ionic elk top movie is when ready to enter REPL. You can see the brief flash on each cycle of the pulse. Bottom is in REPL, just very bright
ionic elk
Yeah that's visibly not the behavior I ahve
tulip sleet
i'm reloading my .bin, will try yours in a minute
ionic elk
Is it possible that it's a different edition of the neopixel, and I haven't hit the sweet spot of compatibility? I noticed there were mentions of timing differences between the WS2812 and WS2812B in the nrf port
tulip sleet
well, I think our boards were made around the same time
have to Saleae the output and check what the clock rates are
ionic elk
if you figure out a way to get a saleae hook on the neopixel please send pics of that too😆
tulip sleet
i can try external neopixels in a bit; still trying to get it into DFU mode
ionic elk
do you not have a stlink available?
tulip sleet
what I have done in the past is to redirect the neopixel pin to another external pin so I can monitor it there.
sure, I do, but I haven't soldered the SWD header on the board yet
ionic elk
not to imply we shouldn't get dfu working properly
yeah you need to use it with extension headers too since it won't fit in a breadboard after you do
tulip sleet
i have to go out in about half an hour and will try again tomw
ionic elk
k
solar whale
@tulip sleet I have had trouble getting to DFU mode. So far it has worked after a few failures. Not sure why.
tulip sleet
it's mysterious. I solder a header on (had to trim one end to make it fit, and am now seeing if my header soldering is any good
solar whale
I’ll try more systematic testing of DFU tomorrow and report.
tulip sleet
ok, GDBServer success
@ionic elk could you pass me a firmware.elf?
from your own build?
ionic elk
lemme get my urandom PR up real quick here
tulip sleet
np, i have to leave imminently, just drop it here when you have a chance
ionic elk
ok, thanks dan
tulip sleet
reloading via j-link gives the same neopixel effect, so it's not a load problem
ionic elk
hmmm
onyx hinge
@ionic elk for scoping you could redefine the neopixel to be on an exposed pin that is easy to probe
