* use a virtual fat filesystem during the test
* this makes the file I/O part more closely patch runtime which is nice
* side-steps the need to add a special function for testing
* but test still can't be run on a device, because the vfs calls
are incompatible, and you intentionally can't remount "/" anyway
* and side-steps problems with storing 'bad' toml files
I wanted to use the idiom
```c
#if GUARD
if (condition) {
alternate code
} else
#else
{
common default code
}
```
idiom, in which the common default code is conditioned both on a
compile-time check and a run-time check. However, I got it wrong
and uncrustify chipped in, adding extra brackets around a following
piece of code and re-indenting it.
* Set nonblock on all accepted sockets. Not just ones for user code.
* Close an open websocket if another is accepted.
* Set debug level to INFO rather than DEBUG because DEBUG crashes
on ESP32-S3 USB OTG.
* read() is now readinto() and takes the buffer to write into.
* readinto() returns the number of valid samples.
* readinto() can be interrupted by ctrl-c.
* readinto() API doesn't support signed numbers because it never did.
* sample_rate is now required in the constructor because supported
values will vary per-port.
* 16 bit values are full range. 12 bit samples from RP2040 are stretched
in the same way they are for AnalogIn.
Fixes#7226
A crash would occur if an SSL socket was not shut down before
`gc_deinit()`.
I do not fully understand the root cause, but some object deinitialization
/ deallocation prior to `gc_deinit` leaves the SSL object in an
inconsistent state.
Rather than resolve the root cause, instead ensure that the closing of
the user socket also closes the SSL socket.
Closes: #6502
Adding `-u ld_include_highint_hdl` forces the linker to keep the
high priority interrupt handler that calls the ipc_isr handler.
The deep sleep is waiting for this interrupt to be handled on core
0 before sleeping from core 1.
Fixes#6090
It doesn't need never reset because the status LED is only active
when user code isn't.
This also fixes PWM never reset on espressif so that deinit will
undo it.
Fixes#6223
danh and microdev1 noticed that this ignore pattern was over-broad
and caused added sdkconfig files in boards/ (which should be committed)
to be ignored and not proposed for addition by common tools like
git status, git gui, etc.
This pattern anchors the search so that it only matches in the
ports/espressif directory, so ports/espressif/sdkconfig is ignored
but ports/espressif/boards/example/sdkconfig is not ignored anymore
This adds the __cause__, __context__ and __suppress_context__
members to exception objects and makes e.g., `raise exc from cause`
set them in the same way as standard Python.
This needs thorough testing before it's merged, as we tried
and reverted this once before (#5341 and #5356).
I think that besides checking for tinyusb having "something to do",
the fact that `port_interrupt_after_ticks` and `port_disable_tick`
weren't implemented that was causing a secondary problem.
I've tested this on a pico w over reboot-cycles and ctrl-c-cycles,
with and without drive automounting, with and without serial repl open,
and on a power-only connection.
I didn't notice the problem reported in #5356 after merely implementing
port_idle_until_interrupt; but I did notice that sleeps in general would
take over-long until "something" (like writing to the USB drive) happened;
I think "something" was probably calling port_enable_tick(). When this
problem was happening, sleeps would take a lot longer; for instance,
`sleep(.001)` would take about 1/20s and `sleep(.1)` would take about 1/7s.
.. a fast helper for animations. It is similar to and inspired by the
PixelMap helper in Adafruit LED Animation library, but with an extremely
fast 'paste' method for setting a series of pixels. This is a common
operation for many animations, and can give a substantial speed improvement.
It's named `adafruit_pixelmap` so that we can package a compatible version
in pure Python for systems that can't fit it in C in flash, or for
Blinka.
This is a proof of concept and can make a very fast comet animation:
```python
import time
import adafruit_pixelbuf
import adafruti_pixelmap
import board
import neopixel
from supervisor import ticks_ms
from adafruit_led_animation.animation.solid import Solid
from adafruit_led_animation import color
pixel_pin = board.GP0
pixel_num = 96
pixels = neopixel.NeoPixel(pixel_pin, pixel_num, brightness=1, auto_write=False, pixel_order="RGB")
evens = adafruit_pixelmap.PixelMap(pixels, tuple(range(0, pixel_num, 2)))
odd_indices = tuple((i, i+2) for i in range(1, pixel_num, 4))
print(odd_indices)
odds = adafruit_pixelbuf.PixelMap(pixels, odd_indices)
assert len(odds) == len(odd_indices)
comet_length = 16
comet1 = [color.calculate_intensity(color.GREEN, ((1+i) / comet_length) ** 2.4)
for i in range(comet_length)]
comet2 = [color.calculate_intensity(color.PURPLE, ((1+i) / comet_length) ** 2.4)
for i in range(comet_length)]
pos1 = 0
pos2 = 96//4
while True:
evens.paste(comet1, pos1, wrap=True, reverse=False, others=0)
pos1 = (pos1 + 1) % len(evens)
odds.paste(comet2, pos2, wrap=True, reverse=True, others=0)
pos2 = (pos2 - 1) % len(odds)
pixels.show()
m = ticks_ms()
if m % 2000 > 1000:
time.sleep(.02)
```
Because this must be treated like an in-use pin for all other purposes,
unfortunately a special case must be added in shared-bindings.
Multiple AnalogIn objects for VOLTAGE_MONITOR can be created (because
in use tracking isn't working) but this causes no harm.
Testing performed: Read the monitor, then imported wifi. When the
pin state was insufficiently restored, the second step would fail
with debug messages about do_ioctl timeout.
```
import analogio, board
a = analogio.AnalogIn(board.VOLTAGE_MONITOR)
print(a.value)
import wifi
```
