Ayush Singh	35f15cfdf2	zephyr/boards/beagleconnect_freedom: Remove board overlay. ... Since MicroPython supports Zephyr v4.0.0, no need for overlay to enable PWM. It is enabled by default for a while now. Signed-off-by: Ayush Singh <ayush@beagleboard.org>	2025-06-23 11:39:43 +10:00

Andrew Leech	d5f2fc239a	extmod/modbluetooth: Add timeout to deinit. ... If the BLE radio stops responding before deinit is called the function can get stuck waiting for an event that is never received, particularly if the radio is external or on a separate core. This commit adds a timeout, similar to the timeout already used in the init function. Updated for nimble, btstack, esp32 and zephyr bindings.

Alessandro Gatti	f47e214cdc	all: Rename the "NORETURN" macro to "MP_NORETURN". ... This commit renames the NORETURN macro, indicating to the compiler that a function does not return, into MP_NORETURN to maintain the same naming convention of other similar macros. To maintain compaitiblity with existing code NORETURN is aliased to MP_NORETURN, but it is also deprecated for MicroPython v2. This changeset was created using a similar process to decf8e6a8b ("all: Remove the "STATIC" macro and just use "static" instead."), with no documentation or python scripts to change to reflect the new macro name.

Maureen Helm	a9803f4711	zephyr: Allow using devicetree node labels to construct machine objects. ... Zephyr v3.7.0 added a new feature to allow getting devices by their devicetree node labels. Use this feature in the MicroPython Zephyr port to simplify constructing machine module objects, including Pin, SPI, I2C, and UART. It's still possible to use the more verbose device names (e.g., gpio@400ff040, i2c@40066000, spi@4002c000), but now we can also use their devicetree node labels (e.g., gpiob, i2c0, spi0). Node labels aren't standardized across all SoC families because they generally try to follow their respective SoC hardware user manual naming convention, however many boards define common labels for devices routed to Arduino headers (e.g., arduino_i2c, arduino_serial, and arduino_spi). That means I2C("arduino_i2c") will work on quite a few boards (>100 in the main Zephyr tree). Signed-off-by: Maureen Helm <maureen.helm@analog.com>	2024-10-01 20:02:01 -05:00

danicampora	6833f3dda9	zephyr: Add threading support. ... This commit implements the `_thread` module on the zephyr port. Due to the fact that we are still using a rather old version of Zephyr, `CONFIG_DYNAMIC_THREAD` is not available and therefore the stack for threads cannot be allocated dynamically, only at compile time. So for the time being and for the purpose of this commit, a maximum of 4 Zephyr threads (besides the main thread) can be created. Once we manage to update to the latest version of Zephyr this won't be a problem anymore. Configuration for the nrf52840dk is added as part of this change, because this board was used to test the threading support. The Zephyr option `CONFIG_THREAD_CUSTOM_DATA` is used to enable threading on a per board basis. The `thread.conf` file is added as a convenient way to enable threading.

Angus Gratton	decf8e6a8b	all: Remove the "STATIC" macro and just use "static" instead. ... The STATIC macro was introduced a very long time ago in commit d5df6cd44a. The original reason for this was to have the option to define it to nothing so that all static functions become global functions and therefore visible to certain debug tools, so one could do function size comparison and other things. This STATIC feature is rarely (if ever) used. And with the use of LTO and heavy inline optimisation, analysing the size of individual functions when they are not static is not a good representation of the size of code when fully optimised. So the macro does not have much use and it's simpler to just remove it. Then you know exactly what it's doing. For example, newcomers don't have to learn what the STATIC macro is and why it exists. Reading the code is also less "loud" with a lowercase static. One other minor point in favour of removing it, is that it stops bugs with `STATIC inline`, which should always be `static inline`. Methodology for this commit was: 1) git ls-files | egrep '\.[ch]$' | \ xargs sed -Ei "s/(^| )STATIC($| )/\1static\2/" 2) Do some manual cleanup in the diff by searching for the word STATIC in comments and changing those back. 3) "git-grep STATIC docs/", manually fixed those cases. 4) "rg -t python STATIC", manually fixed codegen lines that used STATIC.

Maarten van der Schrieck	3bca93b2d0	ports: Fix sys.stdout.buffer.write() return value. ... MicroPython code may rely on the return value of sys.stdout.buffer.write() to reflect the number of bytes actually written. While in most scenarios a write() operation is successful, there are cases where it fails, leading to data loss. This problem arises because, currently, write() merely returns the number of bytes it was supposed to write, without indication of failure. One scenario where write() might fail, is where USB is used and the receiving end doesn't read quickly enough to empty the receive buffer. In that case, write() on the MicroPython side can timeout, resulting in the loss of data without any indication, a behavior observed notably in communication between a Pi Pico as a client and a Linux host using the ACM driver. A complex issue arises with mp_hal_stdout_tx_strn() when it involves multiple outputs, such as USB, dupterm and hardware UART. The challenge is in handling cases where writing to one output is successful, but another fails, either fully or partially. This patch implements the following solution: mp_hal_stdout_tx_strn() attempts to write len bytes to all of the possible destinations for that data, and returns the minimum successful write length. The implementation of this is complicated by several factors: - multiple outputs may be enabled or disabled at compiled time - multiple outputs may be enabled or disabled at runtime - mp_os_dupterm_tx_strn() is one such output, optionally containing multiple additional outputs - each of these outputs may or may not be able to report success - each of these outputs may or may not be able to report partial writes As a result, there's no single strategy that fits all ports, necessitating unique logic for each instance of mp_hal_stdout_tx_strn(). Note that addressing sys.stdout.write() is more complex due to its data modification process ("cooked" output), and it remains unchanged in this patch. Developers who are concerned about accurate return values from write operations should use sys.stdout.buffer.write(). This patch might disrupt some existing code, but it's also expected to resolve issues, considering that the peculiar return value behavior of sys.stdout.buffer.write() is not well-documented and likely not widely known. Therefore, it's improbable that much existing code relies on the previous behavior. Signed-off-by: Maarten van der Schrieck <maarten@thingsconnected.nl>	2023-12-22 10:32:46 +11:00
