Chris Webb	e7aa2a523c	esp8266/modmachine: Support hard IRQ timer callbacks. ... machine.Timer() has inconsistent behaviour between ports: some run callbacks in hard IRQ context whereas others schedule them like soft IRQs. As on the rp2 port, add support to the esp8266 port for a hard= argument to explicitly choose between these, setting the default to False to match the existing behaviour. Open-code this as we don't link against mpirq.c so can't use mp_irq_dispatch(). Signed-off-by: Chris Webb <chris@arachsys.com>	2025-09-25 23:59:24 +10:00

Damien George	b5fcb33eaa	py/mpconfig: Enable CRYPTOLIB, HASHLIB_MD5, HASHLIB_SHA1 if SSL enabled. ... This commit unifies the configuration of MICROPY_PY_CRYPTOLIB, MICROPY_PY_HASHLIB_MD5 and MICROPY_PY_HASHLIB_SHA1, so they are enabled by default if MICROPY_PY_SSL is enabled. This matches the existing configuration of most of the ports. With this change, all ports remain the same except: - reneses-ra now enables MICROPY_PY_CRYPTOLIB, MICROPY_PY_HASHLIB_MD5 and MICROPY_PY_HASHLIB_SHA1. - rp2 now enables MICROPY_PY_HASHLIB_MD5.

Yoctopuce dev	dbbaa959c8	py/formatfloat: Improve accuracy of float formatting code. ... Following discussions in PR #16666, this commit updates the float formatting code to improve the `repr` reversibility, i.e. the percentage of valid floating point numbers that do parse back to the same number when formatted by `repr` (in CPython it's 100%). This new code offers a choice of 3 float conversion methods, depending on the desired tradeoff between code size and conversion precision: - BASIC method is the smallest code footprint - APPROX method uses an iterative method to approximate the exact representation, which is a bit slower but but does not have a big impact on code size. It provides `repr` reversibility on >99.8% of the cases in double precision, and on >98.5% in single precision (except with REPR_C, where reversibility is 100% as the last two bits are not taken into account). - EXACT method uses higher-precision floats during conversion, which provides perfect results but has a higher impact on code size. It is faster than APPROX method, and faster than the CPython equivalent implementation. It is however not available on all compilers when using FLOAT_IMPL_DOUBLE. Here is the table comparing the impact of the three conversion methods on code footprint on PYBV10 (using single-precision floats) and reversibility rate for both single-precision and double-precision floats. The table includes current situation as a baseline for the comparison: PYBV10 REPR_C FLOAT DOUBLE current = 364688 12.9% 27.6% 37.9% basic = 364812 85.6% 60.5% 85.7% approx = 365080 100.0% 98.5% 99.8% exact = 366408 100.0% 100.0% 100.0% Signed-off-by: Yoctopuce dev <dev@yoctopuce.com>	2025-08-01 00:47:33 +10:00

Yoctopuce dev	df05caea6c	shared/timeutils: Standardize supported date range on all platforms. ... This is code makes sure that time functions work properly on a reasonable date range, on all platforms, regardless of the epoch. The suggested minimum range is 1970 to 2099. In order to reduce code footprint, code to support far away dates is only enabled specified by the port. New types are defined to identify timestamps. The implementation with the smallest code footprint is when support timerange is limited to 1970-2099 and Epoch is 1970. This makes it possible to use 32 bit unsigned integers for all timestamps. On ARM4F, adding support for dates up to year 3000 adds 460 bytes of code. Supporting dates back to 1600 adds another 44 bytes of code.

Damien George	398da22492	esp8266/modmachine: Use common machine_time_pulse_us implementation. ... Testing shows that for frequencies which the esp8266 can handle -- up to about 1kHz -- `machine.time_pulse_us()` now gives more accurate results. Prior to this commit it would measure on average about 1us lower, but now the average is much closer to the true value. For example a pulse that is 1000us long, it would measure between 998 and 1000us. Now it measures between 999us and 1001us.

Alessandro Gatti	e4c0e2b73d	esp8266/main: Print error information on crash-induced reboots. ... This commit adds an optional configuration option for the ESP8266 port that, if the board rebooted due to a crash, will print to stdout some information about the error that triggered the issue. It is not possible using regular SDK functions to intercept errors and print information at that stage, and the only error response from the board is to reboot itself. This is the next best thing, print some error information just once at boot time after the crash - the least invasive option given the situation we're in. This is disabled by default, and can be enabled by enabling MICROPY_HW_HARD_FAULT_DEBUG in the port configuration - obviously with a small increase in the firmware code footprint.

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.

Alessandro Gatti	87f04d5935	esp8266/Makefile: Fix local toolchain builds on recent Linux systems. ... This commit fixes compilation for the ESP8266 port when using a local toolchain on relatively recent Linux systems. The documentation asks the user to delete the esptool instance that comes with the toolchain, in favour of using the one provided by the system. On Linux systems that are at least two years old (looking at the CI Ubuntu image as an example), the version of esptool installed with the package manager isn't called `esptool.py` but just `esptool`. The Makefile didn't take that into account and used `esptool.py` without checking if such a command exists, making builds fail. Now preference is given to the `esptool` command, falling back to `esptool.py` only if the former command does not exist or it is not available to the current user, to maintain compatibility with old setups.

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

Angus Gratton	73879734d9	esp8266: Update port to use new event functions. ... This is necessary to avoid watchdog timeout in long i2c.scan(), as previously machine_i2c.c would call MICROPY_EVENT_POLL_HOOK if MICROPY_EVENT_POLL_HOOK_FAST was not available. Compared to previous implementation, this implementation removes the ets_event_poll() function and calls the SDK function ets_loop_iter() from MICROPY_INTERNAL_EVENT_HOOK instead. This allows using the port-agnostic functions in more places. There is a small behaviour change, which is that the event loop gets iterated in a few more places (i.e. anywhere that mp_event_handle_nowait() is called). However, this looks like maybe only modselect.c - and is probably good to process Wi-Fi events in that polling loop. This work was funded through GitHub Sponsors.
