CircuitPython.org updates
We're always updating CircuitPython and the libraries. We've had CircuitPython 4.0.1 stable out for a while, and recently released 5.0.0-alpha.2 which means it's time for a new CircuitPython Library Bundle! The 4.x and 5.x bundles are now available for download at circuitpython.org/libraries. We've stopped supporting the 2.x and 3.x bundles, but you can always get access to the final builds on GitHub.

it wouldn't be on pypi because it's written in typescript

Nothing major to report CircuitPython-wise. Been heads down in the studio tracking some new songs. Trying to wrap up the album this week, working out the duplicating, packaging, and licensing challenges.
My AD9833 Precision Waveform Generator FeatherWing (with CircuitPython drivers) generated some interest. To support a low-power version of the AD9833 that he had on-hand, a maker customized the PCB and ordered some OSH Park boards. Seeing his different perspective gave me some useful ideas. Hoorah for open source!

Has anybody here encountered flash corruption on an ST chip before?

manic glacierBOT

onyx hinge
#

@idle owl I don't have time to test it, but I found a reason based on the datasheet that the ADC on nRF would read about 9% low. I will toss it in a pull request before I head out for the evening.

idle owl
#

@onyx hinge Ok, if you want to toss me a build, I'll test it tomorrow during the day.

onyx hinge
#

@idle owl I think the build will become available from github automatically, if you click through to the build from the PR

idle owl
#

Oh right!

manic glacierBOT
onyx hinge
#

based on what you said and what I understand, this would increase a reading of 3.0V to 3.27V (3.0 * 3.6 / 3.3). That's still not quite the level that you mentioned as "high" voltage..

#

the number "3.6" in the source could be changed to a slightly higher number like 3.65 if it's specifically important to reach 3.29V

#

and there are other options such as (VDD/4) as the reference and (1/4) as the gain. I think in theory using internal reference and (1/6) as the gain gives more accurate voltage measurements, since internal reference varies less than VDD

#

anyway, going AFK. Will read back here or on the PR for your findings! thanks as always for finding these issues and writing them up clearly

It looks like the i2c_device module baked into circuitpython is out of date. If I save the current file from GitHub and change mcp23008 to use the local copy instead, it's fine. (Line 147 in the current i2c_device.py is a comment, not a function call.)

#

"local" whatever... The one in my /lib folder, not the baked-in one.

wind trellis
#

ADDED: Using i2c_device.mpy from the adafrult_bus_device folder in the library bundle (the a la carte version for non-Express boards) also fixes the problem. No TypeError with it.

Thanks, I almost sold out already ๐Ÿ˜„

But more parts are on the way ๐Ÿ™‚

onyx hinge

can some of the pins do touch?

indigo wedge
#

that only requires that the pins can be used as analog in, right?

#

all 6 can be used as analog in

onyx hinge
#

On M0 I'm not sure tbh

slender iron
#

touch requires they be on a Y line to the PTC

@ionic elk at least on samd crystal pins aren't gpio. the swd pins can be

[adafruit/circuitpython] New comment on pull request #2143: STM32: AnalogIO

@tannewt things have been a bit inconsistent, but my texane/stlink program which launches the gdb server does not recognize the flash of the F412 as valid, and cannot load binaries. The F411 was having the same issue, but I was actually able to fix it by erasing it with the windows utility (no luck doing the same for the F412). Latest Analogio code will irrecoverably crash mu (computer must be restarted), and corrupt the flash, making both boards un-debuggable as well as unwritable. Can't get...

[adafruit/circuitpython] New comment on pull request #2143: STM32: AnalogIO

I think I should be. While I reset-protected pins that seemed obviously critical like crystal pins and debugging, I think I must have missed something else that was system critical. My suspicion is that GPIO resets on some pins might even persist past a flash erase. I'm going to invert the never reset process to exclude all pins that aren't directly broken out by the board, and see if that helps.

I've used jekyll before so I could do it once I actually THOUGHT things through instead of firing off untested PRs .. but it should help someone else as well!

i'm jekyll illiterate, but i have experience with ruby and bundler. the latter which has driven me insane with ansible...

but, package management isn't easy. which is why nobody gets it perfect. ๐Ÿ˜„

I would not be comfortable PROGRAMMING ruby, but like so many languages they have made the setup process pretty painless if you start with a working linux system. I assume on mac too.

#

Some aren't supported in 4.x

#

Maybe "a lot of"

orchid basinBOT
onyx hinge
#

the site for the "datum" modules may just be down. and yeah, it's a small number of boards maybe not supported in 4.x, that have 404'd uf2 links

#

besides that the others seem to be false positives due to how links work in jekyll I think - -the link checker thinks e.g., every link to /blinka is 404 because it's /blinka.html

#

but it must be some kind of bug that those boards are listed in _data/files.json as having working 4.1.0 links...?

#

not sure how that file is updated, I guess via adabot?

#

if I manually removed them, would adabot put them back like a jerk?

# 
     39     228    1450
``` hm the datalore_ip_m4 is "in" 4.1.0 source tree
raven canopy
#

yeah, datalore doesn't show up in the assets until 5.0-alpha.1. _data/files.json is updated by build_board_info.py in the core.

onyx hinge
#

is this a case where the board was incorrectly added, like not listed in travis.yml?

#

yeah it is missing in travis.yml of 4.1.0

#

so .. I guess the resolution would be a 4.1.x bugfix to add them to travis.yml. @slender iron ?

#

and do 4.1.1 or 4.2

raven canopy
manic glacierBOT

#

OK I went ahead and tossed in a PR for that. and .. I wasn't going to work on CP tonight or this week. oops

#

fwiw I did bundle add html-proofer (which is wrong, because it tries to configure them as permanent parts of the circuitpython-org build) and then bundle exec htmlproofer ./_site --assume-extension after building the site

raven canopy
#

hehe. its hard to stay away.

onyx hinge
#

it pretty quickly turned up some good issues to work on ๐Ÿ™‚

#

since I don't know the right way to add it for sure, I'm not going to add it to README.md right this second.

it might be harmless to do the bundle add, I am just not confident

#

@slender iron do you know what might be the difference between pyb_i2c.c and just i2c.c in micropython? They're two complete I2C implementations, one that uses the HAL and one that's completely register based, respectively.

slender iron
#

nope no idea

#

pyb is the port specific module.

#

the i2c.c might be used by machine

ionic elk
#

machine?

stuck elbow
#

it's a name of the module in MicroPython that has all the hardware interfaces

ionic elk
#

So in the typical use of micropython, which would get used? the port specific module, or the machine?

#

Would the user pick?

stuck elbow
#

this is an excellent question, and one of the main reasons why CircuitPython changed it

#

you see, the answer is "it depends"

@raven canopy automated b/c the distribution is too smooth (regardless of board popularity)?

manic glacierBOT
raven canopy
#

@crimson ferry yeah, that's what nudged me into thinking that.

craggy galleon
#

Quick question: What is the VREF used for AnalogIn? I am having a bit of a calculation issue and not sure if VREF is set to 3v3 or not. Is it set to internal by default or one of the external PA03 or something?

#

I need to read a 5V voltage from my circuit. I already have a 10k voltage divider but keep getting incorrect values. I keep getting around 8000 instead of higher ones. For 3v3 I get 32,000. Something appears to be going astray behind the scenes

craggy galleon
#

After a bit of investigation, what is happening is that the analog in value is overflowing. I don't understand why this is happening for values like 5v. If someone could explain how I can read in a 0-5v range with circuitpyrhon that would be very helpful :)

@ionic elk clock is first for both I2C and SPI

#

what board are you using?

ionic elk
#

This is for the 411

#

I don't see the order on the common-hal level of course, just the sda and scl pins. Which is why I'm puzzled.

slender iron
#

double check your pin defs

manic glacierBOT
slender iron
#

@ionic elk I spotted an off by one error โ˜

manic glacierBOT
manic glacierBOT
ionic elk
#

@slender iron This is getting into the python end a bit, so I have to ask: does something like busio_i2c_obj_t automatically go away when a circuitpy drive is overwritten? I don't see that either existing port actually calls any module's common_hal_deinit in port.c so I assumed it was done at a higher level.

#

I ask because I've got some kind of conflict that's making the ST's I2C hal write function fail if you save the same code twice, and no amount of hardware-level resets is making it go away. Something is persisting past a soft reboot, and I'm not sure what it could be.

slender iron
#

the memory itself does get freed because the heap is reset

@slender iron Does this code tie in anywhere else? As in, can I simply add it to an existing library that doesn't have it and it will work? I don't see somewhere for it to tie in elsewhere, but maybe I'm missing something. __version__ = "0.0.0-auto.0" __repo__ = "https://github.com/adafruit/Adafruit_CircuitPython_MAX31865.git"

slender iron
#

You just need to add it and ensure that circuitpython-build-tools builds the library. It does the substitution

idle owl
#

if the lib is in the bundle, it's being built, right?

#

These are all older libs that were pre-cookiecutter

#

This one seems to have everything else that cookiecutter adds, except that, so I don't want to redo the entire thing if it's not necessary

Sometimes you have to wait

#

If it re-writes the flash, it takes a long time

#

My command line tool always erases the whole flash, but gdb-load doesn't and there's a big difference between the two. the MBED load system might be closer to the first.

@crimson ferry Yes that is the same set up. So when vbatery is greater than 5v I get the overflow issue.

crimson ferry
#

@craggy galleon if you're dividing 5v in half with the divider, you should be well within the 3.3v max ref. Check both of your resistors separately and make sure they match? Or post circuit and code (maybe better in #help-with-circuitpython )

craggy galleon

Ok. Will do.

@ionic elk which pads are PB09/08?

#

i can get the schem - wish these were labeled tho

#

ok looked up the schem, the 'arduino header i2c' pins are i2c = busio.I2C(board.PB10, board.PB09) # SCL, SDA

manic glacierBOT

ionic elk
#

@meager fog note that I added in some "SDA" and "SCL" labels for the pins in the usual arduino location for I2C.

#

F411 users will have to look up combinations but F412 people can just pretend they're on Arduino as far as pin features go, same as the metros.

meager fog
#

@ionic elk sure

#

@ionic elk do you need another review from @slender iron on the periphral PR

onyx hinge
#

then it turned out (A) the line editing didn't work and (B) neither my C64-owning friend nor I could come up with anything useful to do

obsidian dome
#

Can anyone tell me if I can get a version of circuitpython for the M0 adatalogger that has the audioio and audiobusio modules? It seems to have been left out of the build of circuitpython for this board.

slender iron
#

@onyx hinge awesome!

#

@obsidian dome you can build one yourself. it's left out because the flash is taken up by the filesystem

exotic pumice
#

@onyx hinge yay

#

your friend's monitor is so shiny

obsidian dome
#

If I interpret this right, there is an additional module in the build for the adatalogger to enable reading the SDCard filesystem which took up space, so we left off the audioio? I don't see any extra modules (using help("modules") to look) on the adatalogger in question. What module is this?

solar whale
#

@obsidian dome SDCard access is handled by a separate library adafruit_sdcard. The problem is, I think, that since the is no SPI flash on the adalogger, the CircuitPython Filesystem is in the on-board flash and reduces the space for additional modules like audioio.

crimson ferry
obsidian dome
#

@slender iron Since this seems to be a recurring theme in my life, could audioio become a "loadable" library? Alternatively, which modules would be "candidates" for exclusion to make space for the audioio and audiobusio modules?

slender iron
#

@obsidian dome we could potentially make things loadable with the new native module work damien has done but it's a ton of work

#

audio is tricky because stuff has to happen in the background

obsidian dome
#

I gather there really isn't room for audioio in the on-board flash on these chips. Could I load part of CircuitPython from the SDcard?

#

or maybe all of circuitPython?

slender iron
#

we can't fit audioio and the filesystem within the 256k flash

#

you'll have a much better experience on an samd51

obsidian dome
#

When you say "filesystem", is this something that could be on the SDCard?

meager fog
#

@onyx hinge i love how useless it is!!

river quest
#

@onyx hinge that is super cool, nice work

#

CircuitPython snakes its way to the Commodore 64 (news from 1982, alt universe)

@obsidian dome circuitpython can't only have an sd card filesystem currently

@meager fog whatever you feel is best practice. @slender iron might want to look at it as it contains a number of code style decisions.

ionic elk

@meager fog also, all these tiny STM32 dev boards have reminded me I was close to finishing a pretty enormous tutorial on setting up STM32s with the Black Magic probe/stlinkV2 earlier this summer. Is that something that might be appropriate for Learn?

[adafruit/circuitpython] New comment on pull request #2166: Added SPEAKER and TFT pins to HalloWing M4 for code compatibility

These build errors are your fault. GitHub CI is unreliable. :-/

The original failures could probably be solved by moving us off of "use" statements since they appear to require a download.

The rerun fails because master has had a commit merged and the rerun isn't exactly the same as the original. The workaround for this is to merge master into the PR branch and push the merge commit to trigger a new build.

[adafruit/circuitpython] New review comment on pull request #2151: STM32: peripheral management

Isn't this already done at the application level? I get this behavior by default, and neither the samd or nrf ports have claimed pin checking. Or did you mean checking the I2C peripherals themselves? That's a good idea, since trying to initialize the same peripheral twice will cause IO errors on writing, but I'm not sure how to present that to the user given how we've abstracted the device away.

@ionic elk hiya when you split your PR for adding struct into a new mini-PR let me know

#

and ill test/review it!

ionic elk
#

I just folded it into OS and renamed it, since it was just one line of code

#

^typo

#

There's no HAL component so I just added it in

meager fog
#

@ionic elk i think what @slender iron was saying is dont hvae it based on the I2C PR at all

#

have it be totally separate

#

just the os/struct enabling

#

that way its minial, easy to test and approve/merge

#

lil bite sized PRs

ionic elk
#

Oh, right, the rebase. I don't understand how we can test it without I2C though

meager fog
#

i can totally test it

ionic elk
#

Are there libraries that will work without it?

meager fog
#

just import os and use stat or listdir

#

or struct, and do some struct pack/unpackin'

those are not interdependant on I2C periphearl ๐Ÿ™‚

@ionic elk hiya back

#

im reviewing the i2c stuff now

#

had to get some other folks goin

#

here's the files!

#

do you have a F405 or F407 devboard?

exotic pumice

are there any plans to do F1s?

#

too smol?

ionic elk
#

@meager fog I've got a Pyboard!

meager fog
#

f1's are too small, yeah

#

maybe at some point

#

but tough

#

@ionic elk ok thats perfect

ionic elk
#

@exotic pumice they don't have enough memory but I think it'd be hilarious to do one with external ram and a lot of caching

#

also @meager fog any thoughts on the stm32 tutorial?

manic glacierBOT

#

ok i just merged i2c

#

yay

#

which tutorial?

Anyway I wrote this huge tutorial on getting the stm32 set up with hardware, HAL/rtoses, BMP and STlink debugging, and IDE integration

#

late last spring

meager fog

ionic elk
#

Was originally for somebody else, never published it

meager fog

Was wondering if you'd like it for learn

meager fog

sure - next week mike will be back

#

if ya can hold tight for a few days, mike's the learn guide guide

#

like i have to write a guide on how to DFU fresh stm32 boards cause it is SUPER UNCLEAR

but once you know, its a great thing

#

ok

ionic elk
#

I'd love to integrate that!

#

But yeah I'd just like it to get used

meager fog

onyx hinge
#

I do think it is making progress

meager fog
#

yeah i have to learn what words it says mean

onyx hinge
#

indeed

#

"correct typo" looks like it just started actually building

#

@meager fog so much weird stuff with the M4 DAC

meager fog
#

yah i dunno

#

maybe we have to just shrug

onyx hinge
#

for audio rate and mono it's just fine

meager fog
#

yep

onyx hinge
#

right up until you pointed me at those reports of weirdness in Arduino I was ready to chalk it up to bugs in CP that just weren't fully identified yet

meager fog
#

yah

onyx hinge
#

but .. something in the errata would be nice

meager fog
#

wanna open a ticket with atmel?

onyx hinge
#

"if it's this broken, how is there no erratum about it"

#

I've never done anything like that before!

#

how far do you boil it down so that it's independent of an environment like CP/Arduino before you do something like that?

#

(It won't happen for at least 3 weeks if it's on my plate)

meager fog
#

you basically tell them what you're doin'

#

and see what they say

#

this probably isnt the first theyve heard of it

#

dan can help ya - he's doing one

#

@ionic elk ok while we wait for these PR to bake

#

you are gonna start poking at 405/407?

onyx hinge
#

I will remember to ask him about it then

It's safe to delete old forked-for-PR repos under my github user, right? No reason to keep them, I assume.

tulip sleet
#

@crimson ferry if the PR's have been merged, then all the info you would need has been merged. But you don't need to re-fork for a new PR, if that's what you're doing. Just delete the merged-PR branch, bring the fork up to date with git fetch and git checkout master; git merge upstream/master, and start a new branch.

OK, thanks. I think I skipped the step to make a branch, so it's just master. But I think no harm starting over clean.

i think it's all the overhead with the ft232h

tulip sleet

@tidal kiln the ft232h is pretty fast. i do notice each byte is sent one at a time

#

like there's pretty big delays

#

dunno if you have control over that

#

e.g. can you send i2c buffer all at once

#

let me at least get scan checked and then we can merge

k i believe ya

how about SPI - what did you test with?

ok did the release

#

i think only thing he had to do was brew install libusb you can use the screenshots

i2c being slow is a litle sad but we just have to tell people - hey this is good for sensors, not high speed oled updates

it def works, just is sluggish

@meager fog ok, I see, didn't realize what you were working on. Will take a look and I'll order one.

Note, however, that I was also referring to the Usage Example on the github.com/adafruit/Adafruit_CircuitPython_BLE README page, which is incorrect, as it has "from adafruit_ble.uart import UARTServer" as the first line of the code.

@crimson ferry, thanks! that makes sense. CS on the Gizmo is connected to A6 on CPX and DC is connected to A7.... I tried that and I got another error, but I think it's because of the reset parameter.

#

the line from the guide is: display_bus = displayio.FourWire(spi, command=tft_dc, chip_select=tft_cs, reset=board.D9)

#

and with that I was getting "ValueError: A2 in use" but it looks like D9=A2 on CPX.

#

I tried just taking that parameter out, and the call completes without errors, but when I do the next line I still don't see anything on the screen (was expecting to see the REPL).

I am trying to measure a 1 second pulse. I created a script that outputs a PWM on Pin 13 with 500 pulse width. I have it jumpered to pin 8 on a Metro Express M4. I'm not sure I understand max length and the value in pulses[1]. Is the Value in Millisecond? Many of the values are 65535 (Rollover). Can I get assistance on how this works. Thanks in advance.

#

import time
import board
import pulseio

from digitalio import DigitalInOut, Direction, Pull

led13 = pulseio.PWMOut(board.D13, frequency=1, duty_cycle=500)

pulses = pulseio.PulseIn(board.D8, maxlen=2000, idle_state=False)

while True:
time.sleep(2)

print(len(pulses))
print(pulses[0])

# Clear the rest
pulses.clear()
crimson ferry
#

@strange cargo You'd probably only very briefly see the REPL, if at all, the display.show(splash) line would almost immediately kick the display into displayio and the later appends should then start showing up. Are you doing this line-by-line in the REPL, or as code.py loaded on the CPX? I don't have a CPX or one of those displays, maybe someone else can take a look over on #help-with-circuitpython if you continue to have trouble. Gizmo TFT is so new there's not a Learn guide yet, and I'm not sure if there are any special tricks for it.

strange cargo
#

@crimson ferry, yes I was typing the example line by line in the REPL. one thing I have learned for sure is that it doesn't work to use nylon screws to connect the gizmo to the CPX. since I switched from nylon screws to the (provided) metal ones, I have started to see signs of life: the TFT backlight turns on when I do the line display_bus = displayio.FourWire(...)

#

but I still don't see REPL. I continued through the part of example that draws a green background, but didn't see that either. I think you are right, I should wait for the learn guide. but it's been fun playing around with...

@danh, I've been able to get the eddystone beacon example to work (sort of) on the Circuit Playground Express Bluefruit, and also the following iBeacon:
from adafruit_ble.beacon import LocationBeacon
import _bleio
ย 
company_id = 0x004c
my_uuid = _bleio.UUID('8ce075a8-4fc7-11e8-9c2d-fa7ae01bbebc')
major = 23137
minor = 1
rssi = -60
beacon = LocationBeacon(company_id, my_uuid, major, minor, rssi)
beacon.start(0.5)
ย 
However, both beacons seem to be "once and done". When I reset the CPXB, I receive the beacon advertisement packet only once, regardless off any interval parameter I put on the beacon.start() method call.

I have also been able to interactively do the UARTServer example from the youtube video with the ras pi and nrf52840 express feather, using the REPL on the CPXB. I will try all this on the feather, but I expect the same results...

Is there a way for me to enable CircuitPython syntax check in other editors than Mu or can only you (Adafruit) do that? Like telling it where to look for parseable built-in libraries, or some sort of python/cpython to circuitpython grammar diff? For instance, could I drop these https://github.com/adafruit/Adafruit_Blinka/tree/master/src into a folder and point to it, would that work? Specifically I'm looking for ways to make Visual Studio Code more useful.

@timber mango I think that people have made stubs โ€” python files with empty functions in them โ€” to get that to work for them

slender iron
#

@exotic pumice iirc the gdb dump command

#

@timber mango we have a make stubs command in circuitpython that will create stubs for the C modules. it doesn't include comments yet though

#

once it does we can package it on pypi and then for an editor, you would need to install it

#

@craggy galleon The extra name is easy. You'd also need to plumb together a second set of init code and macros to define the pins. definitely doable

karmic rune
#

Accuracy not that big of an issue. It is an electric meter for solar. It is more of question can pulsein do long pulses (1-2 Second). I'll be happy to do PR and even supply some documentation and/or examples if the will help.

#

Im unsure if Circuit python is the right tool for this . I may want to use a Trinket as a coprocessor using Arduino and interrupts. & Air lift M4 for Web-server.

meager fog
#

for 1-2 second long pulses you could probably poll the pin just fine

#

pulsein is 16-bit so after 65,536us it will overflow

karmic rune
#

My current Raspberry PI has been using polling successfully for many years. I'm trying to tech refresh to more a embedded solution. I'll try to come up with a loop that gives polling adequate polling time. If not I'll try a trinket polling and send data on request from M4 Airlift. (Why write Software when you can throw Hardware at it ๐Ÿ˜€ )

slender iron
#

ya, I'd just poll it too. PulseIn was designed for infrared pulses and DHT. One we basically can't measure with polling

@tough flax I have the XAC_COMPATIBLE_GAMEPAD working on Windows, but not Linux or XAC. I put in some try-``exceptcatches and it is fialing on thegp.reset_all()`. This is true even if I make the gamepad the sole HID device and HID the sole USB device.

There is some work going on in TinyUSB to fix some USB and USB/HID issues, but I'm not sure it's related to this or not. Inquiring about that.

tough flax
#

@tulip sleet are you using just one joystick and 8 buttons?

tulip sleet
#

yes, exact same HID descriptor as the pdp

#

you got it to work in CPy 3.x, if I remember right, before the switchover to tinyusb?

tough flax
#

It was 4.x I think. I sent you a uf2

tulip sleet
#

it's based on your fork, right? I can rebuild that

tough flax
#

My fork didnโ€™t work because of the build instructions

#

Load the uf2 and check the version

tulip sleet
#

still looking for the .uf2 in DM's, but this is interesting from our DM's:
ATMakersBill04/20/2019
Yeah, I got both working as joysticks/gamepads on Windows 10
3.x and 4.x
No complaints and it "just worked"
plugged into the XAC and no joy
Finally dumbed it down to a single HID descriptor
with exactly the specs of their joystick
and it worked on 3.x

#

that is why I'm suspicious of tinyusb here

tough flax
#

Hmmm

#

Perhaps you are right

#

I will grab a uf2 in the morning

Not at my laptop

How often are people dealing with BGA parts when it comes to STM32 development boards? I don't think I've ever actually seen one in person. Trying to determine how high priority it is to add a more complete package management system that accounts for really high pin count MCUs like that.

@craggy galleon did you figure out a final resolution on your 5v analog in saturation question? which board? i have a similar/related issue on pyportal, reading divided battery voltage onto analog in on D3 or D4 connector; in my case Vref seems to change if the PyPortal is powered over USB vs by pushing power into the D3 / D4 connector from a PowerBoost1000 (as recommended by the Portable PyPortal guide). note that the "Vcc" line at D3 / D4 sits at 3.3 v when powered by USB, but gets 5v when powered by PowerBoost. the a/d reads differently in the 2 situations.

meager fog
#

@minor plume open an issue on github is best!

#

@ionic elk hihi i think its inevitable people will use high pin count chips. good news is those chips will also have a ton of flash/ram

#

the pin system ya got should be flexible to 'near infinite' pins - what would be keeping us from having a 100-pin table?

This PR adds the pin and peripheral definitions, linker file, and compilation changes to support the STM32F405.

On my pyboard V1.1, the program currently derails in memory at startup to the CCRAM region and does not reach main. I'd appreciate help locating this issue or replicating it on other F405 devices, particularly if this sounds like a bootloader-related issue to someone more familiar with micropython (I've erased the chip, so this shouldn't be it, right?).

I'm OK either way -- the main issue is how to deal with breaking API's -- In the case oF BLE, I'm not sure it matters too much since the 5.x support add so much, folks will just have to move to it anyway.

Switching from time.time() to time.monotonic() allowed my code to work, but only with time.monotonic() + 0.25, and not with โ€ฆ + 0.2.
