On CPython, and with pylint, the variables MATCH_ROM and SEARCH_ROM are
undefined. This code works in MicroPython because these variables are
constants and the MicroPython parser/compiler optimises them out. But it
is not valid Python because they are technically undefined within the scope
they are used.
This commit makes the code valid Python code. The const part is removed
completely because these constants are part of the public API and so cannot
be moved to the global scope (where they could still use the MicroPython
const optimisation).
This removes the port-specific definition of MP_PLAT_PRINT_STRN on the
windows port, so that the default mp_hal_stdout_tx_strn_cooked() is always
used. This fixes releasing the GIL during the call to write() (this was
missed in bc3499f010).
Also, mp_hal_dupterm_tx_strn() was defined but never used anywhere so it is
safe to delete it.
This removes the port-specific definition of MP_PLAT_PRINT_STRN on the unix
port. Since fee7e5617f this is no longer a
single function call so we are not really optimising anything over using
the default definition of MP_PLAT_PRINT_STRN which calls
mp_hal_stdout_tx_strn_cooked().
Zephyr v2.2 reworked its gpio api to support linux device tree bindings and
pin logical levels. This commit updates the zephyr port's machine.Pin
class to replace the deprecated gpio api calls with the new supported gpio
api. This resolves several build warnings.
Tested on frdm_k64f and mimxrt1050_evk boards.
The "led" argument is always a pointer to the GPIO port, or'd with the pin
that the LED is on, so testing that it is "1" is unnecessary. The type of
"led" is also changed to uint32_t so it can properly hold a 32-bit pointer.
Updating the LED0 state from systick handler ensures LED0 is always
consistent with its flash rate regardless of other processing going on in
either interrupts or main. This improves the visible stability of the
bootloader, rather than LED0 flashing somewhat randomly at times.
This commit also changes the LED0 flash rate depending on the current state
of DFU, giving slightly more visual feedback on what the device is doing.
Also support MP_STREAM_GET_FILENO ioctl. The stdio flush change was done
previously for the unix port in 3e0b46b9af.
These changes make this POSIX file implementation equivalent to the unix
file implementation.
Fixes UDP non-blocking recv so it returns EAGAIN instead of ETIMEDOUT.
Timeout waiting for incoming data is also improved by replacing 100ms delay
with poll_sockets(), as is done in other parts of this module.
Fixes issue #5759.
Adds support in the zephyr port to execute main.py if the file system is
enabled and the file exists. Existing support for executing a main.py
frozen module is preserved, since pyexec_file_if_exists() works just
like pyexec_frozen_module() if there's no vfs.
Enables the zephyr usb device stack and mass storage class on the
mimxrt1050_evk board. The mass storage class is backed by the sdhc disk
access driver, so it's now possible to browse and modify the contents of
the SD card from a USB host (your PC). This is in preparation to support
writing a main.py script to the SD card, and then executing it after the
next reset.
Adds support in the zephyr port to mount a file system if a block device
(sdhc disk access or flash area) is available. The mount point is either
"/sd" or "/flash" depending on the type of block device.
Tested with an sdhc disk access block device and fatfs on the
mimxrt1050_evk board.
Tested with a flash area block device and littlefs on the reel_board.
This commit adds micropython.heap_locked() which returns the current
lock-depth of the heap, and can be used by Python code to check if the heap
is locked or not. This new function is configured via
MICROPY_PY_MICROPYTHON_HEAP_LOCKED and is disabled by default.
This commit also changes the return value of micropython.heap_unlock() so
it returns the current lock-depth as well.
This is an extremely minimal port to the NXP i.MX RT, in the style of the
SAMD port It's largely based on the TinyUSB mimxrt implementation, using
the NXP SDK. It currently supports the Teensy 4.0 board with a REPL over
the USB-VCP interface.
This commit also adds the NXP SDK submodule (also from TinyUSB) to
lib/nxp_driver.
Note: if you already have the tinyusb submodule initialized recursively you
will need to run the following as the tinyusb sub-submodules have been
rearranged (upstream):
git submodule deinit lib/tinyusb
rm -rf .git/modules/lib/tinyusb
git submodule update --init lib/tinyusb
This eliminates the need for the sizeof regex fixup by rearranging things a
bit. All other bitfields already use the parentheses around expressions
with sizeof, so one case is fixed by following this convention.
VM_MAX_STATE_ON_STACK is the only remaining problem and it can be worked
around by changing the order of the operands.
The double-% was added in 11de8399fe (Jun
2014) when such errors were formatted with printf. But then
55830dd9bf (Dec 2018) changed
mp_obj_new_exception_msg() to not format the message, as discussed
in #3004. So such error strings are no longer formatted and a % is just
that.
This commit changes the BLE _IRQ_SCAN_RESULT data from:
addr_type, addr, connectable, rssi, adv_data
to:
addr_type, addr, adv_type, rssi, adv_data
This allows _IRQ_SCAN_RESULT to handle all scan result types (not just
connectable and non-connectable passive scans), and to distinguish between
them using adv_type which is an integer taking values 0x00-0x04 per the BT
specification.
This is a breaking change to the API, albeit a very minor one: the existing
connectable value was a boolean and True now becomes 0x00, False becomes
0x02.
Documentation is updated and a test added.
Fixes#5738.
