MP_REGISTER_MODULE would use identifiers like
"MODULE_DEF_MP_QSTR___FUTURE__" which would in turn cause
a QSTR to be generated for it. This wasn't desirable, because the
qstr would never be used.
This clears out quite a bit of flash storage on the proxlight trinkey.
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.
.. 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)
```
We adopted the file "py/ioctl.h" and the ioctl names beginning
with MP_IOCTL_POLL while micropython went with "py/stream.h" and
MP_STREAM_POLL.
Align with upstream.
Closes#6711
Note: at this time, the ssl module on pico_w never verifies the server
certificate. This means it does not actually provide a higher security
level than regular socket / http protocols.
My pings go out, and then they come back
```py
import os
import wifi
import ipaddress
wifi.radio.connect(os.getenv('WIFI_SSID'), os.getenv('WIFI_PASSWORD'))
ipv4 = ipaddress.ip_address("8.8.4.4")
print("Ping google.com: %f ms" % (wifi.radio.ping(ipv4)*1000))
```
Recently(?) github started making it the default to only copy a single
branch (e.g., main) and NO TAGS into new forks.
This makes the step of the build process that determines the CircuitPython
version not work, because tags are expected to be present. When tags are
not present, the version number is only a git hash. The version number
ends up being 0.0.0.
This causes problems with libraries that check for CircuitPython version
to determine compatibility, among other things.
We'll do other things to improve the situation, such as document it.
But it'd also be good if the build stopped when this detectable condition
occurs.
.. the default is intended to be the equivalent of the original,
implementing `DISPLAYIO && TERMINALIO`.
This is a possible alternative to #6889, if I understand the intent.
