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.
Originally, black_bindings found each contiguous "//|" block and sent
it to black independently. This was slower than it needed to be.
Instead, swap the comment prefix: when running black, take off
"//|" prefixes and put "##|" prefixes on all un-prefixed lines.
Then, after black is run, do the opposite operation
This more than doubles the overall speed of "pre-commit run --all",
from 3m20s to 55s CPU time on my local machine (32.5s to under 10s
"elapsed" time)
It also causes a small amount of churn in the bindings, because
black now sees enough context to know whether one 'def' follows another
or ends the 'def's in a 'class'. In the latter case, it adds an extra
newline, which becomes a "//|" line.
I'm less sure why a trailing comma was omitted before down in
rp2pio/StateMachine.c but let's roll with it.
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))
```
Based on esp32s3, all available pins are drawn.
2M PSRAM, 8M FLASH.
A JST SH 4-pin Connector can be used for STEMMA QT / Qwiic.
A MX 1.25mm 2-Pin Connector Lithium battery power supply.
A WS2812 LED.
Adds support for the BananaPi BPI-Bit-S2 Boards.
Based on esp32s2 chip.
With 25 ws2812 LEDs, 1 buzzer, 2 photosensitive sensors, 1 thermosensitive sensor,
2 buttons on the front, 1 reset button and 1 boot button on the back.
Add them as MICROPY_HW_LED_STATUS so that we can share reset code
for them. They aren't actually used for the status if another RGB
option is available. (But maybe they should be.)
Fixes#6717
This allows the web workflow send code to yield briefly when
waiting for more room to send in a socket. Waiting for an "interrupt"
could wait forever because the select task only waits for read and
error. Adding wait on write is tricky because much of the time we
don't care if the sockets are ready to write. Using yield avoids
this trickiness.
We may have set retries to 0 to enforce a timeout but the connect
succeeded. When it succeeds, we want to allow retries later in
case we lose signal briefly. (The callback will do this too but
the connect function will override it after.)
Also, remove extra code from websocket that is leftover from
debugging.
.. this setting can be overridden with a bigger or smaller value in
CIRCUITPY/.env but 1/8 of PSRAM seems like a good initial value. It's
enough to store a single 800x600 or 640x480 RGB565 frame, or multiple
smaller frames such as 320x240.
This uses the esp32-camera code instead of our own homebrewed camera code.
In theory it supports esp32, esp32-s2 and esp32-s3, as long as they have
PSRAM.
This is very basic and doesn't support changing any camera parameters,
including switching resolution or pixelformat.
This is tested on the Kaluga (ESP32-S2) and ESP32-S3-Eye boards.
First, reserve some PSRAM by putting this line in `CIRCUITPY/_env`:
```
CIRCUITPY_RESERVED_PSRAM=524288
```
and hard-reset the board for it to take effect.
Now, the following script will take a very low-resolution jpeg file and print
it in the REPL in escape coded form:
```python
import board
import esp32_camera
c = esp32_camera.Camera(
data_pins=board.CAMERA_DATA,
external_clock_pin=board.CAMERA_XCLK,
pixel_clock_pin=board.CAMERA_PCLK,
vsync_pin=board.CAMERA_VSYNC,
href_pin=board.CAMERA_HREF,
pixel_format=esp32_camera.PixelFormat.JPEG,
i2c=board.I2C(),
external_clock_frequency=20_000_000)
m = c.take()
if m is not None:
print(bytes(m))
```
Then on desktop open a python repl and run something like
```python
>>> with open("my.jpg", "wb") as f: f.write(<BIG PASTE FROM REPL>)
```
and open my.jpg in a viewer.
.. the primary user of which will be the camera, since the framebuffers
must be allocated via esp-idf allocation function and never from the
gc heap.
A board can have a default value, and the value can also be set in the
/.env file using the key CIRCUITPY_RESERVED_PSRAM with the value being
the reserved size in bytes.

The ringbuf used to fill up and the recv interrupt would block CP.
Now it'll disable the interrupt until we have enough room in the
ringbuf.
Fixes#6678
* Fixes#6221 - C3 hang on `import wifi`. Enabling the WiFi PHY was
disabling USB. Now boards that use it set CONFIG_ESP_PHY_ENABLE_USB
explicitly.
* Fixes#6655 - Allows pasting into the web serial page. Fixes reading
more than 0xf bytes at a time.
* Fixes#6653 - Fixes web socket encoding of payloads >125 bytes. Can
happen when printing a long string.
* Fixes C3 responsiveness when waiting for key to enter REPL. (It
now correctly stops sleeping.)
* Disables title bar updates when in raw REPL. Related to #6548.
* Adds version to title bar.
It had a tight 5ms timeout before that caused some characters to
drop. Now the wait is longer and reset after a successful transmit.
This follows what MicroPython does.
Fixes#6220
1. Run the socket select task at the same priority as CP. This is
needed because it queues up the background work. Without it, CP
needed to sleep to let the lower priority task go.
2. Close the active socket on disconnect. This prevents looping
over a disconnected but not closed socket.
Fixes#6610. Fixes#6613
- define CIRCUITPY_BUILD_EXTENSIONS to predefined values
- set CIRCUITPY_BUILD_EXTENSIONS in port and board config
- reuse the support matrix "get_settings_from_makefile" to get it
- move the existing port and board specific values
- remove the C3 specific board values because it's not the default
- update build_release_files.py to use get_settings_from_makefile
- Based on espressif/nimble's blecent example code. Confirms that the characteristic is not empty before trying to catalogue its descriptors.
- Running ble_gattc_disc_all_dscs on empty (no length) characteristics fails with the (not-very-informative) BLE_HS_EINVAL error if this check is not performed.
.. this makes reconnecting without a full reset not work.
Because this works on other generations of the esp32 (c2, c3, etc),
apply this behavior only to esp32.
After this change, it's possible to connect multiple times to wifi in
different runs of code.py or the repl after soft rebooting.
Format:
CIRCUITPY_BLE_NAME = My BLE Board
- the length is limited to 31 characters
- for the NRF version it repeatedly truncates the name if it's too long
- the ESP version defaults to "nimble" if the name is too long
rather than setting the heap size statically, micropython allocates
the biggest contiguous chunk possible, but in no event more than half the
total internal sram. On esp32 this gives 123728 bytes of `gc.mem_free`
in the repl.
Also, change error handling so that the esp-idf error number
is shown in the traceback in the case of an error.
This allows scanning & connecting to work. I didn't try requests yet.
esp32 places the psram start at SOC_EXTRAM_DATA_LOW and it can extend
up to SOC_EXTRAM_DATA_SIZE. This is different than esp32-s2 and later,
which place the end at EXTRAM_DATA_HIGH and the limitation of
SOC_EXTRAM_DATA_SIZE was not previously identified as important.
Additionally, the esp32 has a reserved area within himem which was
not being accounted for.
With this change, the Feather ESP32 V2 feather can be used via thonny,
and the other "quick memory corruption tests" I was performing
also all succeed instead of failing.
Before this change, the incorrect address being used for spiram was
0x3fa00000..0x3fc00000 (2MiB). Now, it's 0x3f800000..0x3f9c0000 (1.75MiB)
due to the reserved area and the changed start address.
This is intended to be a no-effect change for other espressif chips besides
original esp32.
