I want to make my own circuitpython board.
My idea is to make a board like the ItsyBitsy M4 with ATSAMD51G19A 48-pin,
BUT with a crystal (like the Feather M4).
Q1: I think I have to make my own board variant under circuitpython/ports/atmel-samd/boards/ , right ?
(is it enough to state "#define BOARD_HAS_CRYSTAL 1" / where can I define what kind of crystal ?)
Q2: Do I have to make my own variant of the UF2-Bootloader binary then as well ?
(or does the bootloader only vary regarding the processor version [internal flashsize / RAM size] ?)
tulip sleet
@timber mango There's a standard crystal at a a standard frequency. You can just copy the Feather stuff to your own board.
The UF2 bootloaders vary based on chip and pins used for status indication (e.g., NeoPixel or DotStar or just an LED, and on what pins). And they ID the chip based on a USB Vendor ID/Product ID (VID/PID) which is different for each board.
timber mango
@tulip sleet thanks Dan,
- so it is not possible to use a different crystal than the "standard" 32.768 kHz crystal, right ?
- and the UF2 bootloaders "doesn't care" if there is a crystal or not ? -> so you think I could use the stock ItsyBitsy M4 UF2-bootloader-binary then ?
tulip sleet
@timber mango The chip supports using a 32kHz crystal and/or a 0.4-30MHz crystal (on different pins). However, we don't provide any clock initialization support using other than the 32kHz crystal.
The UF2 bootloader now always is crystalless, so as long as your status RGB LED is set up the same way, it should work. If this is just for you, then you could use the same bootloader, but if you are distributing these, you should figure out your own USB PID/VID.
timber mango
@tulip sleet OK thanks for clarification, so the statement "#define CRYSTALLESS 1" within uf2-samdx1/boards/itsybitsy_m4/board_config.h is not needed (or has no effect anymore) ?
tulip sleet
it's also in inc/uf2.h, so everything is crystalless.
timber mango
I see now ....

FrequencyIn:
- Added user configurable
capture_periodattribute. Has 1ms - 500ms range for now; will decide minimum and maximum after more testing. - Removed EIC latency adjustment, and simplified the math. Hoping this allows me to approach adjustment from a fresh perspective. Getting about 10% fluctuation in readings from a min/max perspective. This is mostly the variation in the capture period, not EIC latency, since the period can be up to 900us beyond the set capture period. Note: I finally did the math on EIC latency; even with a 48MHz clock (GCLK_EIC), latency per event is in the nanosecond range.
- Added user configurable

https://github.com/adafruit/Adafruit_CircuitPython_MMA8451/blob/master/adafruit_mma8451.py#L196
idle owl
@slender iron I found a bug in register related to our update. The bit_mask was still set to (1 << 8) which didn't allow for manipulating bits 8+. This is my fix: if self.bit_mask >= (1 << (register_width * 8)): raise ValueError()It works, but I'm not sure it's correct.
Allows for more than 2 byte registers. My original fix was change 8 to 16.
slender iron
@idle owl can you link to the context?
idle owl
I didn't push it anywhere. I'll upload the file here.
Otherwise when I tried to change a bit range in the 8-15 range, it threw a ValueError.
exotic pumice

@marble hornet Yep - for read the docs?
marble hornet
yes
prime flower
CharLCD is a good library to look at for reference on how to make the docstrings (since it's had so many eyes on it)
^ as an example
slender iron
@idle owl I don't think you want to multiply the shift
idle owl
Ok then what should I set it to? 8 fails.
slender iron
well its making a bitmask to apply to the particular byte the value is in
raven canopy
@marble hornet also...here are the nitty gritty docs on Sphinx. this exact link is to the rST primer, but the entirety lives there. http://www.sphinx-doc.org/en/master/usage/restructuredtext/basics.html
slender iron
so it makes sense that its between 0 and 7 because its on a byte
idle owl
Except you told me to make it know I'm in the high byte, I have to use 8-15 when using RWBits
slender iron
for lowest_bit yes
idle owl
right
slender iron
internally that info is split into byte and bitmask
and lowest_bit
I think lowest_bit needs to become byte local (0-7) rather than for all of the bytes
this is related to lowest_bit // 8 for byte
idle owl
ok.
slender iron
because you want lowest bit to be the remaining bits
so lowest_bit_in_byte = lowest_bit % 8
idle owl
I don't remember what I did to make it fail before. It failed on that line so that's why I though it was related to that line
then what do I do with lowest_bit_in_byte
slender iron
I think it should be used to compute bit_mask and saved as lowest_bit
otherwise the math in get and set is wrong
idle owl
I don't know how to do that.
I also don't understand how it will know I'm working in the high byte at that point either. but I'm not entirely understanding the change, so that's not surprising.
slender iron
self.byte knows which byte get and set are in
idle owl
ok
slender iron
so init needs to set lowest_bit and bit_mask so it works on the single byte we care about

gusty topaz
Guys, a couple of quick questions:
a. Why can't Raspbian detect a Circuitpython board with CP4 when connected to one of the USB ports (like it does on Mac and Windows)?. Do I need to install a special package?. (I'm feeding the board from two different USB parts since the RPI doesn't seem to provide enough juice to the board).
b. What's currently the cheapest WiFi capable CircuitPython board/option?
main meteor
I think the $17 Feather Huzzah is the cheapest WiFi capable one.
solar whale
a) not sure -- it shuuld work b) there are no WiFi boards currently supported for CP 4
gusty topaz
@main meteor but the huzzah is not compatible with CP, right? (only Micropython)
gilded cradle
Isn't the Particle Argon supported by CP4 and it has Wifi?
raven canopy
Huzzah 8266 is supported up to CP3.x, but it's not USB capable so you have to use ampy for programming/file xfer. For future support, to include the Argon, you have to use the new ESP UART/SPI library.
tulip sleet
@gusty topaz RPi should be fine driving a board unless it has tons of other stuff drawing power. It's only a few tens of mA. I just plugged a Grand Central into an RPi and connected via /dev/ttyACM0
Argon build does not include wifi support
we have dropped ESP8266 as of 4.0.0
raven canopy
@tulip sleet does the RPi auto-mount the MSC though? I think that is the question...
tulip sleet
yes it does, just fine
@gusty topaz what RPi board and what version of Raspbian are you running?
show uname -a and cat /etc/issue

solar whale
@gilded cradle the Argon runs CP in the nrf52840 portion -- it does not use the ESP32 chip -- it can be used as a coprocessor wit the ESP32ATControl library
umbral dagger
The adapter code (devices/si7021.py): ```import adafruit_si7021
def make_si7021(i2c_bus):
return adafruit_si7021.SI7021(i2c_bus)

})
Ok, that's what I thought, but it IS still wifi capable, correct?
main meteor
@gusty topaz I see a binary release for CircuitPython here https://github.com/adafruit/circuitpython/releases/tag/3.1.2
solar whale
@raven canopy FYI -- the ESP32SPI will not work on the argon π¦ only the UART --
@gilded cradle yes, but not in the CP code. You have to laod a special image to the ESP32 and then send "AT" commands to the ESP32 via the UART. The CP does not have anything to do with the WiFI access.
gilded cradle
Thanks @solar whale . I'll have to get some of the particle boards at some point so I can be more familiar with their capabilities.
solar whale
they are fun to use -- both with CP and the Particle mesh software
but for Wifi access -- now I would recommend an ESP32Huzzah with a feather (m4 or nrf52840) and the ESP32SPI interface.
or wait for the new board to come out
gilded cradle
Ok, I have both of those. I wasn't sure how to get the special image onto the ESP32huzzah though
solar whale
I can send you instructions in a little while -- the SPI stuff is very new and there is no guide ...yet
but basically you use esptool to upload it via USB -- just like you would load micropython to it.
If you don't mind waiting until this evening, I can write up some instructions.
prime flower
@gilded cradle the LoRa boards are also fun - weird at first - but fun
gilded cradle
Thanks @prime flower . I'll take a look at those when I get a chance, but am pretty immersed in the featherwings at the moment.
prime flower
there's a featherwing LoRa radio π
gilded cradle
Oh boy. I guess I'll have to take a look at that. π
Yeah, there's like 4 of them
prime flower
Are you in the US?
prime flower
You'll want one with the RFM95 (LoRA/LoRAWAN compatible) with a 900mhz radio (915mhz tx/rx)
gilded cradle
Ok, do you need at least 2 in order to test them?
prime flower
You would need two or a Radio Bonnet (https://www.adafruit.com/product/4074) and one for LoRa/LoRAWAN
gilded cradle
Ah yeah, ok. Well I added them to my wishlist.
prime flower
tbh, I'd wait until the radio bonnet is back in stock. It's the quickest/cheapest way (currently) to get started w/LoRaWAN
gusty topaz
@solar whale what new board?
gilded cradle
That's probably what I'll do, hence adding it to the wishlist. π
gusty topaz
@tulip sleet I'm using a Raspberry Pi 3 Mod. B and Raspbian Jessie.
solar whale
@gusty topaz My understanding is the there is a board with the integrated esp32 in the works -- thats all I know
tulip sleet
@gusty topaz I'd suggest you upgrade to the latest, stretch
stretch has been out for almost two years
gusty topaz
@solar whale ohh. you are right!, I think @meager fog mentioned it in one of the videos, but I think it'll have the "Metro" form factor. I prefer the Feather form.
tulip sleet
also the USB thing is suspicious. Maybe the DC supply you're using for the Rpi is inadequate. Try a beefier AC adapter first
gusty topaz
@tulip sleet I know, I know... the thing is that I have a bunch of scripts (Python 3) in it and everytime I update it, it breaks something.
tulip sleet
how are you powering it?
tulip sleet
2.5A power supply is recommended, especially if you have USB devices and are using HDMI
and wifi
gusty topaz
@tulip sleet computer USB.... but it's not just the board. It's a tripler with a GPS featherwing, PArticle Xenon, Oled display, SD card breakout ... so yeah, it may be related to current consumption. The wierd thing is that I powered the tripler from two USB ports (2nd one coming from a different computer.. just power, no data).
No HDMI, the RPI has a WiFi dongle connected only.
@solar whale are you referring to this guide? to use CP + WiFi Coprocessor? https://learn.adafruit.com/adding-a-wifi-co-processor-to-circuitpython-esp8266-esp32/overview
umbral dagger
Wht are the odds of getting CP supported on the new Pyboard-D? It looks pretty sweet.
inland tusk
@idle owl Wheln tCP 4.0 is released don't forget to update the main board gu ide to include the fact that USB-midi is available
solar whale
@gusty topaz that is for the UART "AT" interface to the EPS8266 or ESP32 -- there is a new library to support a much more robust SPI interface https://github.com/adafruit/Adafruit_CircuitPython_ESP32SPI
only for the EPS32
tulip sleet
@gusty topaz that's probably OK from the USB ports, BUT the overall power supply must be good too. If you're just powering the RPi from a host computer USB port, that's probably not good enough.
the RPi will draw way more power than what's on your tripler
@umbral dagger completely different chip (STM), which we don't have a port for, so it would be a big job
a 1A phone charger probably is not enough
umbral dagger
@tulip sleet Mostly a peripheral issue?
umbral dagger
I thought as much.
meager fog
@umbral dagger heyyy happy tuesday. i have some time now - wanna figure out what projects to schedule for rest of feb?
umbral dagger
@meager fog Sure. What do you have in mind? I have the RPLIDAR in progress, and a pyportal should show up later today.
@meager fog More cheatsheet stuff?
gusty topaz
@solar whale π€ Interesting.... sounds great, but I think I will go with the Huzzah+Micropython for the WiFi option. I already have that board and MP is good enough for what I will do with it (sucks not having USB support, though). Would love to see a WiFi + CP ready board in feather form.
umbral dagger
There's plenty of directions we can push that in
solar whale
@gilded cradle were you interested in the "AT" interface is the guide above or the new ESP32SPI interface -- or both?
meager fog
@umbral dagger i think the RPLIDAR really needs a graphical display to show it off, and we don't quite have that yet
gilded cradle
Oh I tried with the guide, but it appears to be oriented more towards the esp8266.
meager fog
we used the ESP8266 at first but it fell over too much, ESP32 is really needed
gilded cradle
Ok, that's what I was trying to use
meager fog
yeah its a very :/ chip
gusty topaz
@solar whale (Side note: the GPS logger w/CP 4, Particle Xenon, OLED, GPS Featherwing and SD CArd breakout is working beautifully. Running some tests and so far so good. Will be uplading a write up to my blog soon).
umbral dagger
I, also, had trouble with the esp8266 AT interface. I have that project deferred until the esp32 breakout is available.
meager fog
@umbral dagger how about you try the raspi 3d scanner w/crickit
solar whale
@gilded cradle the guide does not have the instructions for loading the AT firmware to an ESP32 via esptool/USB - that is easy -- I'll get it to you.
meager fog
there's no additional hardware or libraries you need that we don't have ready
gilded cradle
Thanks @solar whale
meager fog
@umbral dagger and there's existing software to do the scanning - you're just swappin' out the code that rotates a platform
umbral dagger
Crickit isn't even needed. 1 digital output to turn the motor on/off should suffice, based on my current understanding.
solar whale
hmm getting 503's from adafruit learn system ..
meager fog
nah you need to step thru the rotation slowly?
you can't just turn the motor on/off - it has to sync with the software taking pix
umbral dagger
I thought the oboard controller did that.
meager fog
sry - whats oboard?
umbral dagger
It spits back a series of readings, one for each rotational increment
meager fog
im super confused π can you point me to it?
umbral dagger
You just tell it to start scanning, then sit back and consume the readings
meager fog
yah but how do you know where the readings relate to the rotation?
either way you still have to power the DC motor
but i think a stepper works way better
umbral dagger
umbral dagger
Sorry .. mybad... I completely glossed over that.
meager fog
yeah for RPLIDAR you just read from serial - so the driver is just reading values and then parsin' them into a pointcloud
loll
umbral dagger
Yes. you are right
meager fog
very similar!
umbral dagger
similar, but sort of inside out
Yes.. I have what I need for that. Need to coordinate with the Bros
We started that but both got distracted, I guess.
meager fog
np π
we haven't had any raspi crickit projects so i think it would be good to have one or two
to get people some examples of how it can be used
@umbral dagger for RPLIDAR you could try running the circuitpy library on raspi to display it
solar whale
@meager fog -- I just realized that the AT coprocessor guide has out-of-date instructions for loading the AT firware to an ESP32 Huzzah-- the file to load is not linkked. Would you like me to update it -- Ok to just provide the "big" file for single file load.
meager fog
that might be a good way to test it - probably the most likely ussecas
@solar whale oof - that guide needs a serious scrubbin' now that ESPSPI is released
solar whale
do you want them in the same guide?
meager fog
@solar whale long term yeah -
do you want to try restructuring the guide? cause basically there's 2 use cases now
Particle ESP32 w/AT and Other with ESP32 SPI
anything else i dont mind documenting but its very π€·
maybe we can put the ESP8266 stuff in one page and say "this is incredibly flakey and not suggested"
solar whale
so drop the AT Firmware for the Huzzah32
solar whale
agreed!
meager fog
the difference is significant - i can download 250KB files in 4 seconds with SPI
solar whale
OK -- I'll try to work on it some - probalbly tomorrow.
meager fog
ok thanks - i delayed doing any edits till ESPSPI was out - which is is as of...noon today
@umbral dagger ok so ya got this lispy thing going, do you want to finsih that first?
gusty topaz
@meager fog any plans to release a CP board w/ WiFi in Feather form?
meager fog
dragon, not immediately but hopefully if we can find a module thats a resaonsble size
first up is a metro, lotsa space π
@solar whale if i can bug ya to review my changes to https://github.com/adafruit/Adafruit_CircuitPython_Touchscreen/pull/2
i'd like to get that bundled and off my plate π½
umbral dagger
@meager fog That's pretty much ready to wrap up. Some crickit support would be nice to add first. But I've proven out a modular way to support i@c device drivers, reusing the CP libraries.
solar whale
@meager fog I have some working example using "setings.py" for post to AIO and cheerlisghts -- do you want me to put in a PR with them to the ESP32SPI repo or do have some other examples.
meager fog
@umbral dagger (love i it)
meager fog
i think i2c is good enough to publish
umbral dagger
crickit, depending on how the ram of the feather M4 is... I've been workign on a Grand Central
meager fog
we dont have tons of spi devices
umbral dagger
OK, cool.
solar whale
@meager fog I did review -- do you want me to merge?
meager fog
@umbral dagger wanna put that down for publishing... on thursday? or what day works best?
@solar whale oh yayy thanks
done
umbral dagger
OK... I have to spend a day or two later this week on HackSpace. I'm at the point with lispy that I can switch focus to writing it up.
The device support was the last big hurdle, and that just fell into place this morning
meager fog
word - ok how about... friday? we can adjust, but good to have some rough idea
any day ya like
umbral dagger
So.. end of tomorrow, or sometime Thursday to submit the guide?
Certainly by Friday.
meager fog

Actually, the HS article will be pretty straightforward this month... mostly theory & intro stuff. No project work. (Intro to integrated circuits).
meager fog
nice - those articles are amazing
umbral dagger
That's a great one. I like the lisp/jedi strip, too.
meager fog
π
ok after that - RPLIDAR on raspi?
but driver in 'circuitpython'?
i think we'd actually be using pyserial, but still good to have it be circuitpy compatible (e.g. pure python and memory concious)
and then it can be run on microcontroller once we have a way to plot the data
umbral dagger
Sounds good
meager fog
you can probably heavily borrow from https://github.com/SkoltechRobotics/rplidar
and give em credit
umbral dagger
nice
meager fog
yeah you just want to pass in the Uart object instead of a string
and maybe remove the logger code
ok wanna put down a prelim date of....22nd?
& can adjust?
umbral dagger
That should work
meager fog
ok then you can check out the 3d scanner stuff after - ill put down prelim march 1st - all adjustable if you need more time π
umbral dagger
Awesome
meager fog
self driving car should be easier to do with all those done first - cause you'll have the pieces

Question: do you know of a nice readline type library in python that'll run on CP? The LISPY REPL input is uber barebones (just reads a string of characters from stdin... no editing)
meager fog
oi
well in circuitpy we dont have the ability to read a char at a time
unless you're using it over a UART not USB
umbral dagger
It also doesn't echo spo I had to find a terminal app that I could set local edit on (ended up using minicom)
Like... even backspace would be nice to have π
I think I'll add the ability to have it check for code.scm and autoload that on startup.
umbral dagger
I wonder if GNU readline could be compiled into the runtime... That's what I usually use for such things

omg @slender iron this is awesome !

The fellow with the tricorder on S&T might have something as well
marble hornet
what's that?

I've been using Pycom LoPy boards for some wearable project prototypes. I like the embedded Micropython and want to use the same on the feather Huzzah32 from Adafruit. Unless I've missed something that board isn't yet one listed on the GitHub repository.
Is there anyone planning to adapt CircuitPython for the Huzzah32 with the ESP32 micro?
umbral dagger
Lispy on the Fetaher looks good: ```Adafruit CircuitPython 4.0.0-beta.2 on 2019-02-05; Adafruit Feather M4 Express with samd51j19
soft reboot
Auto-reload is on. Simply save files over USB to run them or enter REPL to disable.
code.py output:
Lisp loaded, free mem: 124800

lispy>
That should be plenty of space.
main meteor
Probably a little trickier on the more space-constrained Feathers.
umbral dagger
It's just a matter of not having as much space for the lisp code/data. The Grand Central leaves almost 200K, the Feather about 125K. I haven't done any analysis yet of how it uses space.
125K feels like it should be plenty for a lot of things.
Lispy, itself, is fairly small.

@slender iron Monday is a US holiday, should we move the weekly to Tuesday?
slender iron
yup, probably

display = displayio.Display(display_bus, init_sequence, width=320, height=240)
but I thought there was a way to now do it with out providing the init_script. Do you have an example? Alos any other examples handy would be great -- I need to make some changes to my display_text tests.
@gilded cradle given the earlier conversation -- do you just want to jump into the ESP32SPI -- I can provide you with the load file and some instructions. If you still want to try the AT firmwate on the ESP32 I can give you that as well. Whatever you prefer.
gilded cradle
I think I'll give the ESP32SPI a try
solar whale
OK -- here is the .bin file to load -- instructions follow
ESP32SPI file
flash it with /usr/local/bin/esptool.py --chip esp32 --port /dev/ttyUSB0 --baud 115200 --before default_reset --after hard_reset write_flash -z --flash_mode dio --flash_freq 40m --flash_size detect 0 NINA_W102.bin
you may have to make some OS dependent changes for you esptool and port
gilded cradle
I have a mac, so that should work...
solar whale
what board are you going to usi it with -- I'll geve you the pin connections
gilded cradle
I could either use a Huzzah32 feather or I have the DevKitC, though I'd prefer to use the wing
err feather
solar whale
ok -- I have both as well -- what board are you connecting it to
gilded cradle
Well, let's go with the M4 Metro since I don't think that one's in use at the moment
marble hornet
if there is a board with display built in can i find the width and height from board.DISPLAY or do i need to know it?
solar whale
perfect -- just what i have metro_m4 to huzzah32 -- give a few minutes to get the pins.
main meteor
Oops, my first attempt to build CP failed. It may be because I'm using a too-recent version of gcc.
gilded cradle
In my experience @marble hornet , you generally need to know it, but I could be wrong.
exotic pumice
@main meteor, yeah gcc8 has problems
marble hornet
so a user will need to input it if using a lib?
solar whale
@main meteor I use ```gcc version 7.3.1 20180622 (release) [ARM/embedded-7-branch revision 261907] (GNU Tools for Arm Embedded Processors 7-2018-q3-update)
@main meteor are you running 8 and if so do you want my makefile?
main meteor
Yeah, I'm running 8. Maybe I should just grab 7.
gilded cradle
@marble hornet , usually only when initializing a library
solar whale
but if I recall correctly the q3 is a lie -- it was q2
exotic pumice
@main meteor, ok, yeah, I seem to have lost the makefile in a git reset
gilded cradle
Unless it's designed for a specific screen size
exotic pumice
I think
main meteor
I am interested in that Makefile, but I'm guessing it disables problematic warnings like error=stringop-truncation
exotic pumice
yup
tulip sleet
tinyusb runs into some issues with gcc8. I fixed some of those temporarily to get it to build. I was just trying to see if the build was noticeably smaller (it was smaller, but only by a little bit).
exotic pumice
hey dan, I accidentally pinged you in a gitter channel you're not even in, so if you get a notification just ignore it
exotic pumice
just telling someone I followed your advice to run the dfll in open loop
gilded cradle
Ok @solar whale , I got the file flashed onto the Huzzah32 successfully
exotic pumice
I've gone as far as to not touch the dfll part of oscctrl and my problem persists
solar whale
just typing up the pinouts
slender iron
main meteor
Okay, I was able to build it successfully with gcc 7, thanks!
solar whale
@gilded cradle I use these pins ```ESP32 METRO_M4
RST D5
GND GND
USB +5
33/A9 D10
14/A6 MOSI
SDA/23 MISO
SCK/5 D9
MOSI/18 SCK
Ok, I'll give it a try and let you know if I have any difficulty.
solar whale
OK here are the pins used in the example
ESP_BUSY = D10
ESP_RESET = D5 ```as well as MISO/MOSI/SCK
gilded cradle
Thanks
solar whale
good luck -- once you get the simpletest to run -- I have better examples
gilded cradle
Ok
exotic pumice
I'm really starting to wonder if I have hardware/calibration issue. Can someone try loading this on their metro m4 and measure d13 for me?
I know dan already did but that was an older version
that had the incorrect dfllmul
this is the one that doesn't touch dfll
solar whale
@slender iron FYI -- I get this on a feather_m4_express ?? ```

arduino has the same problem!
holy cow
let me double check it actually uploaded
ok I lied
gilded cradle
@solar whale, I keep getting ESP32 timed out on SPI select and have triple checked the wiring according to what you gave me.
solar whale
hmm -- I had that at one point as well -- but rechecking the wiring fixed it ... make sure you jumpers are all good - I has some the just were not working.
gilded cradle
Is there supposed to be something connected to D9?
Oh, wait, I think I need to change that from D9 to D6
solar whale
yes CS -- to SCK/5 -- sorry
gilded cradle
Ok, that fixed it
solar whale
wait
gilded cradle
and it worked
solar whale
ok -- trying to see what I had wrong above
gilded cradle
You had me set ESC_CS to D9, but wire it to D6
solar whale
just D6 -> D9
gilded cradle
Yeah, thanks. You said you had other examples
solar whale
yes -- but I have to go for a few hours -- sorry -- I'll try to get thme posted later this evening. -- do you have a neopixel string on the metro -- good for one of the examples
gilded cradle
Not currently, but I could wire one up
solar whale
its a nice touch. sorry to hold you up.
gilded cradle
It's ok. Sounds good about posting them later.
solar whale
OK -- will do.
gilded cradle
Thanks again

has anyone tried the set_boundary with the mirror off?
i'm hazing izzues
i can;t get x_end of any width shape past 31
slender iron
slender iron
so it seems to work but doesn't render correctly?
marble hornet
yeah, i can;t set end_x to anything great that the height of the shape. i get a ValueError: x value out of bounds
slender iron
hrm that sounds like a bug π
marble hornet
agweed shall i?
slender iron
you can fix and pr π
marble hornet
oh found another bug

can i wipe the flash somehow? i can;t get to the terminal
slender iron
@marble hornet does the status LED go yellow for a bit?
marble hornet
yes
slender iron
if you click reset when it is then it'll go into safe mode
and not run your bad code
marble hornet
can you give me an example? or number of ms? (to get an idea)
i;m trying different amounts of delay
but it is not working
raven canopy
like getting into BIOS on PC startup? (closest analogy i can think of)
slender iron
too fast and you'll stay in the bootloader
too slow and circuitpython will start in regular mode
marble hornet
now whenever i hit reset-it goes right to boot loader mode
marble hornet
i have
slender iron
have you power cycled?
marble hornet
yes
let me try the stock firmware that come on it
the arduino.uf2
nope
isn;t there a safe-mode uf2? or was the decision changed out for this?
slender iron
ya, broken for me here too
marble hornet
i think i have an idea
i'm gonna compile w/out displayio and then chagne the main.py
if it works ill post the uf2
i wonder if it is;t the displayio
building clean, taking a while
#define CIRCUITPY_DISPLAYIO (0) correct?
just commenting it out didn;t work

So is there a guide to MemoryError issues? Iβm driving 70 neopixels and only have 250 lines of code. Iβm hitting memory errors immediately if i add new code
tulip sleet
@wild pasture what board and what version of CircuitPython, and what other libraries are you using besides neopixel?
marble hornet
@meager fog what resistance is the screen for the portal?
tulip sleet
@wild pasture this might be useful: https://learn.adafruit.com/circuitpython-essentials/circuitpython-expectations#frequently-asked-questions-19-8
wild pasture
@tulip sleet CPX board, all im importing is time, board, neopixel, random and digitalio. Sorry, i should have mentioned. Iβve searched here and otherwise and didnt see a how-to on memory profiling/issues or code writing tips
tulip sleet
what version of CircuitPython?
wild pasture
@tulip sleet i tried the latest stable 3 and the very recent beta 4. I did see that page but was hoping for more tips/how to profile etc. Or even a guide βif you need more than X code, dont even bother, jump straight to c codeβ
tulip sleet
did you try 3.1.2, as opposed to 3.1.0? (just making sure)
wild pasture
@tulip sleet yeah, just checked my downloads folder and it was 3.1.2
tulip sleet
try brightness=1.0 on the neopixels. Brightness other than 1.0 doubles the neopixel memory. But for 70 neopixels, that's not a huge amount. You could post you code in a gist or upload it here (use the + sign to the left), and we can take a look
wild pasture
I love this little guy btw! I just need to be able to write more code! Background is CS major, ex MS engineer. I did try makecode too but i consistently had crashes with the code it produced
tulip sleet
it's very fun!
250 lines is actually getting big. Are you getting the memory error in import or when running?
wild pasture
@tulip sleet yeah i did finally see the brightness tip which helped my initial memory limits. That was buried.
exotic pumice
@tulip sleet remember when I thought I fixed my clocks but later still had issues? Well, if I set the GCLK divider to 4 on a SRC of DFLL, I get 12MHz, but if I set it to 1 I get 6MHz
tulip sleet
are you sure the bitmask is right?
tulip sleet
maybe check the actual bits
tulip sleet
not very much
exotic pumice
ok, I think I found a bug in startup.c
tulip sleet
you mean do i work on our board support pkgs?
pls do file an issue. the samd51 code is pretty new
exotic pumice

@meager fog I'd love to use that Arduino sauce, just ran into an issue

exotic pumice
@tulip sleet svd/x reports the division factor of 1
solar whale
@gilded cradle posting example to set neopixels string based on "cheerlights" website
cheerlights example
settings example
these use the settings.py file to hold "secrets" like passwords/ keys -- for this you only need you ssid and password. it does not use the aio items. Check the pin assignments and number of neopixels.
Do you have an Adafruit IO accout that you can post to? I have an example for that if you want it.
tulip sleet
@exotic pumice did you look at the whole register in svd just to make sure it corresponds with the datasheet?
exotic pumice
I'm looking at the code autogenerated from the svd now and it looks strange
exotic pumice
@tulip sleet, I know you don't read Rust but anyways,
impl<'a> _DIVW<'a> {
#[doc = r" Writes raw bits to the field"]
#[inline]
pub unsafe fn bits(self, value: u16) -> &'a mut W {
const MASK: u16 = 65535;
const OFFSET: u8 = 16;
//self.w.bits &= !((MASK as u32) << OFFSET);
self.w.bits |= ((value & MASK) as u32) << OFFSET;
self.w
}
}
The commented out line looked strange to me so I commented it out, but it didn't make a difference
marble hornet
neat way of doing it
gilded cradle
Thanks @solar whale. I don't think I have an adafruit IO account or at least I've never used it if I do. Let me check...oh I guess I do have one.
exotic pumice
otherwise it's the same I think
the C version is
#define GCLK_GENCTRL_DIV(value) (GCLK_GENCTRL_DIV_Msk & ((value) << GCLK_GENCTRL_DIV_Pos))
where mask is 0xffff and pos is 16
tulip sleet
@exotic pumice whats the DFLL multiplier value?
exotic pumice
0
solar whale
@gilded cradle np -- I am revising the demo -- will post it after I check it out -- try the cheerlights.
gilded cradle
Ok, I'll try it out.
tulip sleet
@exotic pumice in our code is DFLL MUL 1 or 0?
The datasheet says it's a multiplier, and doesn't say what 0 does.
tulip sleet
those are for close-loop mode, so they may not do antyhing
exotic pumice
ok
I'll double check that it's still 0 but last time you checked
yeah, 4.0.0alpha5
Fields in OSCCTRL DFLLMUL:
MUL: 0x0000 DFLL Multiply Factor
FSTEP: 0x00 Fine Maximum Step
CSTEP: 0x00 Coarse Maximum Step
@exotic pumice the two lines in the rust above. the &= clears the bitfield, and the |= sets it. you need both
tulip sleet
you and out an inverse of the mask to clear the bits, and then you or in the bits you want
tulip sleet
because the DFLL is in open loop mode, I think all the DFLLMUL values don't matter - it' just trying to output 48 MHz. So you're feeding that into a GCLK, and then dividing?
exotic pumice
yeah
tulip sleet
are you setting DFFLVAL.COARSE and .FINE? THose are the factory calibration values, so don't change them
exotic pumice
I commented out everything that touches the dfll
tulip sleet
well, you have to enable it, etc.
exotic pumice
actually you don't
tulip sleet
DFLLCTRLA.ENABLE ?
raven canopy
DFLL is auto-enabled on 51.
tulip sleet
ok
exotic pumice
yep, it's on according to svd/x, but I didn't set it
exotic pumice
fn set_gclk_divider_and_source(
&mut self,
gclk: ClockGenId,
divider: u16,
src: ClockSource,
improve_duty_cycle: bool,
) {
self.gclk.genctrl[gclk.bits() as usize].write(|w| unsafe {
w.src().bits(src.bits());
w.div().bits(divider);
w.idc().bit(improve_duty_cycle);
w.genen().set_bit();
w.oe().set_bit()
});
self.wait_for_sync();
}
which gclk are u using?
solar whale
@gilded cradle oops found a cut/paste error in the previous version - if you create a feed named "test" and put your aio username and key in settings.py the script will post an incrementing counter to it.
tulip sleet
what does w get bound to in the rust code above? It looks like a smalltalk lambda variable
exotic pumice
I don't really know how all that works but the .write() is a closure that takes w and then you do all your write operations on w, it's just like, bitwise or'ing all the stuff
gilded cradle
Hey @solar whale , I actually have to get going for a bit. Something came up. I'll give it a try as soon as I'm able to get back online. Thanks
marble hornet
@solar whale can you give me some help with that touch screen lib? i'm not getting good readings
plz
solar whale
@gilded cradle no rush
@marble hornet I'll try -- what are you getting
@marble hornet are you just using the "simpletest"
tulip sleet
@exotic pumice how does configure_glck_divider_and_source() call set_gclk_divider_and_source() ?
exotic pumice
it's just a wrapper that returns the output frequency
marble hornet
yes (the text from it exactly)
exotic pumice
pub fn configure_gclk_divider_and_source(
&mut self,
gclk: ClockGenId,
divider: u16,
src: ClockSource,

};
self.gclks[idx] = Hertz(freq.0 / divider as u32);
Some(GClock { gclk, freq })
}
}
i'm getting only around 320 abd 197
solar whale
no matter where you touch?
marble hornet
but no more no less
pretty much yeah every now and then it drop
s
than goe back to that vlaue
tulip sleet
@exotic pumice how are you measuring the output freq? I thought you were using something that was only good to 24 MHz?
exotic pumice
yeah that's correct
marble hornet
but i know the hardware is right ! because the arduino example shipped with the pyp works
tulip sleet
so a divider of one will be unmeasurable by your test equipment
marble hornet
and quite well
tulip sleet
you'll probably get weird aliasing results
exotic pumice
yeah, I got different weird results in C though
marble hornet
how did you calibrate ur screen?
exotic pumice
and a dimmer led
solar whale
@marble hornet i didn't -- try just getting raw vaules ```import board
import adafruit_touchscreen
These pins are used as both analog and digital! XR and YU must be analog
and digital capable. XL and YD just need to be digital
ts = adafruit_touchscreen.Touchscreen(board.A1, board.A2,
board.A3, board.A4)
while True:
p = ts.touch_point
if p:
print(p)
well... that might be due to something else like some skew setting or something that changes the waveform shape. If you can test the dividers with values you can meausre, and they seem reasoanble, then I think it's the measuring
exotic pumice
I'll try a divider of 2
tulip sleet
yah try 2,3,4,5,6,7,8 and see if you get results you expect
etc. I know better test equipment is expensive, but maybe it can be borrowed at least for this
marble hornet
trying
exotic pumice
divider of 2 gives 3 MHz lol

so on the pyp there are: 'TOUCH_XL', 'TOUCH_XR', 'TOUCH_YD', 'TOUCH_YU'
solar whale
put them in in that order

@exotic pumice that's still at the limit of your equipment 48/2

take out the calibration/size
marble hornet
i'll turn off the things you have turned off
exotic pumice
yeah the other values look decent
solar whale
I could not read te numbers -- do they vary
exotic pumice
ok, well, that's a little maddening
tulip sleet
@exotic pumice yah so the 24MHz limit is just messing with your conception of the output. what kind of device is that
exotic pumice
solar whale
mine vary from 10000 to 50000 across the screen
marble hornet
no
tulip sleet
yeah, since that's sampling that will really mess with higher frequencies.
marble hornet
little to none
exotic pumice
it was such a stable 6 though lol
tulip sleet
The Nyquist reate for 24Mhz sampling is 12MHz, the highest frequency you can accurately measure
this is not anything like a 24Mhz analog scope, which will roll off at higher freqs
solar whale
@marble hornet hmm -- no idea --- sounds likea hardware issue -- I don't have any information on that board
tulip sleet
@exotic pumice you might want to feed the GCLK2 output into another GCLK and divide it down further for easier measuring
then monitor that GCLK and do the mental multiplication
exotic pumice
welp, I guess that wraps it up then, onto the next thing, figuring out why my 200ms delay was coming out as 92ms
marble hornet
okay thank you. ood tho that it works well in arduino but not cp
solar whale
good to know -- then it makes less sense -
solar whale
did you try using your finger instead of the stylus
marble hornet
hmmm idk ill try switcing them around it's only 4! -1 combinations π
π
i'll look at the schem
solar whale
also need to know they are correct in pins.c
as @meager fog pointed out -- you will get results as long as they are paired correcly.
raven canopy
hah! take that enable-protected register! i win.
don't mind me. just fighting with proper deinit function π
marble hornet
@solar whale the pin defs are wrong
trying now to fix now
i think
i'm not sure
recompiling
@solar whale you were right
solar whale
are you getting good results now?
marble hornet
yay
raven canopy
alright. tomorrow, double back and re-test M0. then...merge the endless commits that have passed since i last updated this branch. jinx warning: FrequencyIn might be done this week. π΅
marble hornet
Slow because I'm taking a normal display via displayio but it runs. I might flip the jumper tommorow to spi
solar whale
Very nice! Congratulations!
marble hornet
thanks
i;ll need ot branch adn do a diplayio version or switch the portal to spi ** for tommorow
night all
solar whale
Good Night!
exotic pumice
is it normal for dpll0 to only get up to 104MHz instead of 120?
marble hornet
@river quest @meager fog @slender iron please see the vidπ. 6 before this one

Unfortunately, the usb cable that came with my Tenma 72-10405 DMM doesn't seem to be compatible with Linux. I'll have to do some more research on that. But I got a serial to USB adapter (using the PL23030 chipset) off Amazon and am able to use it with the serial (DB9) cable.
I found a unix/linux/macos prgram called QtDMM and after a bit of poking around was able to find some manual settings that worked with my meter.

Cool! Blogs like Portable Adafruit.com? And WOW. LADYADA really crammed EVERYTHING in there. There isn't a free pin. Excluding swd
exotic pumice
it sounds like we all got a lot done today, pats on the back all 'round
exotic pumice
g'night
tulip sleet
@exotic pumice note that te DPLL divisor calc is +1:
tulip sleet
or if it's the DFLL, surprised it's off by so much, maybe the calibration values are off?
I have seen a lot of jitter in the DFLL on a scope, but the avg was still about 48 MHz
exotic pumice
hmm
tulip sleet
dunno why they'd be off if you're not setting them
exotic pumice
should I try to fix them?
tulip sleet
no, I wouldn't change them. Do you have only one sample chip?
tulip sleet
hmm, don't know what to say, just maybe double-check that nothing is messing with the factory values on setup
but you said not
exotic pumice
there's some calibration stuff in our code but I turned it off
exotic pumice
dunno, the samd21 code has some calibration stuff I never looked into, I just turned it off for 51
looks like it's just reading it
tulip sleet
yeah
exotic pumice
actually, setting it here, https://github.com/atsamd-rs/atsamd/blob/d453ca895b84e5db209129ea9e2d467814465d34/hal/src/clock.rs#L440
but just the same value it read back or some errata value
tulip sleet
why is fine 0x1ff? Need to look at that.
exotic pumice
that's for '21 idk
not my problem lol
Fields in OSCCTRL DFLLVAL:
FINE: 0x80 Fine Value
COARSE: 0x23 Coarse Value
DIFF: 0x0000 Multiplication Ratio Difference
so it's automatic
not exactly sure what this implies. I think we have USB CRM turned on
exotic pumice
yours was afaik
tulip sleet
i dunno. I'm fading but maybe I'll measure our DFLL freq some time
exotic pumice
ok
tulip sleet
good night and good luck
exotic pumice
turning it on had no effect for me
good night
oh I missed the mode bit
yeh, still 888.9
lol
that's cool
anywho, 4.0.0beta2 has usbcrm off

Interesting, I get the proper 1MHz if I run my atmel studio project
so there must be something messing with it
is it the on demand bit messing me up?
exotic pumice
nope
exotic pumice
fixed!
solar basin
I'm waiting for addition hardware to come in. Should be a couple days\
exotic pumice
@solar basin don't worry about it I just fixed sercoms!
the samd51 pr should be pretty much ready to go in a bit
noble mango
anyone at adafruit every thought about also seeing if erlang ? It was created by Ericsson and made to work with multi cores.
incomplete sentences... thinking to fast and never listened to by english teacher to check twice. Check to see if erlang would work on todays multicore chips.. It will cork but what about space requirements.
exotic pumice
@noble mango microcontrollers are typically single core
tulip sleet
@exotic pumice great! so tell us what was wrong when you're around again
marble hornet
I'm trying to get the pyportal working with spi I switched the mode jumper to 3v3 and tried the TFT_RS to SCK jumper in both positions but no luck. Any special sauce I'm missing in my attempt?

@gilded cradle have you tried chaning the cheerlight setting? just send a tweet to #cheerlights blue or any color you want see https://cheerlights.com/cheerlights-api/
gilded cradle
I didn't, but saw others change it
solar whale
Thanks for testing the examples -- glad it is working for you.
gilded cradle
You're welcome. It was fun.
solar whale
the esp32spi is so much more reliable than the AT (UART) -- far fewer errors and retries.
gilded cradle
Yeah, I figured, which is why I wanted to test that one.
marble hornet
if i show a group then change a group it will change the screen on the next refresh?
exotic pumice
@tulip sleet, this is the issue that messed me up for 2 months
kind of infuriating
tulip sleet
what's the issue? Did you have the wrong GCLK index?
exotic pumice
have a look at TC0 and TC1
