PicoDVI in CP support 640x480 and 800x480 on Feather DVI, Pico and
Pico W. 1 and 2 bit grayscale are full resolution. 8 and 16 bit
color are half resolution.
Memory layout is modified to give the top most 4k of ram to the
second core. Its MPU is used to prevent flash access after startup.
The port saved word is moved to a watchdog scratch register so that
it doesn't get overwritten by other things in RAM.
Right align status bar and scroll area. This normally gives a few
pixels of padding on the left hand side and improves the odds it is
readable in a case. Fixes#7562
Fixes c stack checking. The length was correct but the top was being
set to the current stack pointer instead of the correct top.
Fixes#7643
This makes Bitmap subscr raise IndexError instead of ValueError
when the index arguments are wrong.
Fixes polling thread looping forever hangs preventing new connections.
Don't lose listening sockets on mp resets and re-init.
Keep better separation of "system" and "user" sockets.
Track socket states to prevent re-use of sockets before closed.
Close REST socket when transaction completes. No post-init.
Remove unnecessary state flags.
This reverts commit 7e6e824d56.
Fixes#7770
The change in #7623 needs to be revered; the raise-site added in #7632
is the correct one and the one in socketpool needs to be reverted.
This is not affecting 8.0.x because #7623 was not back-ported to there
before we realized it was not a full fix.
Both #7770 and #7606 should be re-tested. I didn't test.
It now handles deinit, never_reset and sharing tracking. PWM
now runs in the WAIT state as well during a time.sleep().
_reset_ok() was removed because it was called in one spot right
before deinit().
Some PWMOut were also switched to a bitmap for use instead of
reference count. That way init and deinit are idempotent.
Fixes#6589. Fixes#4841. Fixes#4541.
Rather than returning the negative error value.
This is intended to close#7606, though I did not test with mqtt.
Instead, I created a simple standalone test program:
```python
import wifi, socketpool, ssl, time
#wifi.radio.connect(<omitted>)
import socketpool
socket = socketpool.SocketPool(wifi.radio)
ctx = ssl.create_default_context()
b = bytearray(8)
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sss = ctx.wrap_socket(s, server_hostname='example.com')
sss.connect(('example.com', 443))
sss.setblocking(False)
r = sss.recv_into(b)
print(r, b) # prints 4294967285 which is -11 as unsigned
sss.close()
```
Before the change, r was the out of range value 4294967285. After the
change, the recv_into call raises OSError instead.
This is comparable to the behavior on standard Python, though an
SSLWantReadError is raised instead.
The original (mis)behavior seems to match what was uncovered deep inside
minimqtt by adding logging:
```
370.578: DEBUG - PKT: _sock_exact_recv: recv_len = 4294967285
```
Watchdogs are used to reboot out of the bootloader. There is a
scratch register for user watchdogs. So use sdk functions to better
distinguish these.

Now, open wifi works on Pico W, so this closes#7438.
For the web workflow it's now OK to either
* specify an empty password string (as before)
* not have the CIRCUITPY_WIFI_PASSWORD key at all (new functionality)
* 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
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
```
Closes: #7020
This is the lwip no-os version of SO_REUSEADDR, which is set on all
listening sockets in the espressif port; do so here as well,
it makes running servers easier. The "address in use" error does
not occur.
You might wonder how this fixes a problem with PulseIn, when the
changes aren't to any of those files! PulseIn is implemented in terms of
StateMachine, which had some assumptions about the relation between
the index of a pin object in mcu_pin_global_dict_table and its "pin
number". This was true, until some pins were removed from the
microcontroller module on Pico W.
Closes: #7078
Weirdly we have to stop the AP too (which we never started),
or cyw43_tcpip_link_status still reports that STA is connected.
As long as AP mode isn't implemented, this doesn't matter and
we can just do it.
