When loading a manifest file, e.g. by include(), it will chdir first to the
directory of that manifest. This means that all file operations within a
manifest are relative to that manifest's location.
As a consequence of this, additional environment variables are needed to
find absolute paths, so the following are added: $(MPY_LIB_DIR),
$(PORT_DIR), $(BOARD_DIR). And rename $(MPY) to $(MPY_DIR) to be
consistent.
Existing manifests are updated to match.
Remove the 240MHz CPU config option from sdkconfig.base and create a new
sdkconfig.240mhz file for those boards that want to use 240MHz on boot.
The default CPU frequency is now 160MHz (was 240MHz), to align with the ESP
IDF and support more boards (eg those with D2WD chips).
Fixes issue #5169.
This prevents issues with concurrent access to the ringbuf.
MICROPY_BEGIN_ATOMIC_SECTION is only atomic to the same core. We could
address this with a mutex, but it's also not safe to call mp_sched_schedule
across cores.
This avoids a confusing ENOMEM raised from gap_advertise if there is
currently an active connection. This refers to the static connection
buffer pre-allocated by Nimble (nothing to do with MicroPython heap
memory).
This commit adds support for a second supported hash (currently set to the
4.0-beta1 tag). When this hash is detected, the relevant changes are
applied.
This allows to start using v4 features (e.g. BLE with Nimble), and also
start doing testing, while still supporting the original, stable, v3.3 IDF.
Note: this feature is experimental, not well tested, and network.LAN and
network.PPP are currently unsupported.
This patch uses the newly-added esp32.Partition class to replace the
existing FlashBdev class. Partition objects implement the block protocol
so can be directly mounted via uos.mount(). This has the following
benefits:
- allows the filesystem partition location and size to be specified in
partitions.csv, and overridden by a particular board
- very easily allows to have multiple filesystems by simply adding extra
entries to partitions.csv
- improves efficiency/speed of filesystem operations because the block
device is implemented fully in C
- opens the possibility to have encrypted flash storage (since Partitions
can be encrypted)
Note that this patch is fully backwards compatible: existing filesystems
remain untouched and work with this new code.
As per PEP 485, this function appeared in for Python 3.5. Configured via
MICROPY_PY_MATH_ISCLOSE which is disabled by default, but enabled for the
ports which already have MICROPY_PY_MATH_SPECIAL_FUNCTIONS enabled.
Replaces the `SDKCONFIG` makefile variable with `BOARD`. Defaults to
BOARD=GENERIC. spiram can be enabled with `BOARD=GENERIC_SPIRAM`
Add example definition for TINYPICO, currently identical to GENERIC_SPIRAM
but with custom board/SoC names for the uPy banner.
They are both enabled by default, but can be disabled by defining
MICROPY_HW_ENABLE_MDNS_QUERIES and/or MICROPY_HW_ENABLE_MDNS_RESPONDER to
0. The hostname for the responder is currently taken from
tcpip_adapter_get_hostname() but should eventually be configurable.
This commit adds the connect() method to the PPP interface and requires
that connect() be called after active(1). This is a breaking change for
the PPP API.
With the connect() method it's now possible to pass in authentication
information for PAP/CHAP, eg:
ppp.active(1)
ppp.connect(authmode=ppp.AUTH_PAP, username="user", "password="password")
If no authentication is needed simply call connect() without any
parameters. This will get the original behaviour of calling active(1).
On this port the GIL is enabled and everything works under the assumption
of the GIL, ie that a given task has exclusive access to the uPy state, and
any ISRs interrupt the current task and therefore the ISR inherits
exclusive access to the uPy state for the duration of its execution.
If the MicroPython tasks are not pinned to a specific core then an ISR may
be executed on a different core to the task, making it possible for the
main task and an ISR to execute in parallel, breaking the assumption of the
GIL.
The easiest and safest fix for this is to pin all MicroPython related code
to the same CPU core, as done by this patch. Then any ISR that accesses
MicroPython state must be registered from a MicroPython task, to ensure it
is invoked on the same core.
See issue #4895.
Without this you often don't get any DNS server from your network provider.
Additionally, setting your own DNS _does not work_ without this option set
(which could be a bug in the PPP stack).
WIFI_REASON_AUTH_FAIL does not necessarily mean the password is wrong, and
a wrong password may not lead to a WIFI_REASON_AUTH_FAIL error code. So to
improve reliability connecting to a WLAN always reconnect regardless of the
error.
This updates ESP IDF to use v3.3-beta3. And also adjusts README.md to
point to stable docs which provide a link to download the correct toolchain
for this IDF version, namely 1.22.0-80-g6c4433a-5.2.0
This adds support for SD cards using the ESP32's built-in hardware SD/MMC
host controller, over either the SDIO bus or SPI. The class is available
as machine.SDCard and using it can be as simple as:
uos.mount(machine.SDCard(), '/sd')
The patch solves the problem where multiple Timer objects (e.g. multiple
Timer(0) instances) could initialise multiple handles to the same internal
timer. The list of timers is now maintained not for "active" timers (where
init is called), but for all timers created. The timers are only removed
from the list of timers on soft-reset (machine_timer_deinit_all).
Fixes#4078.
This also fixes deleting the PPP task, since eTaskGetState() never returns
eDeleted.
A limitation with this patch: once the PPP is deactivated (ppp.active(0))
it cannot be used again. A new PPP instance must be created instead.
