Damien George	03b4c60fc1	nrf/modules/machine/spi: Print SPI baudrate, polarity and phase. ... On most ports, printing an instance of machine.SPI gives something like: >>> machine.SPI(1) SPI(1, baudrate=328125, polarity=0, phase=0, bits=8) This commit makes the nrf port do the same. The reason for this change is: - make nrf consistent with other ports - allow the `tests/extmod/machine_spi_rate.py` to run on the nrf port (this tests parses the output of str(spi) to get the actual baudrate) Signed-off-by: Damien George <damien@micropython.org>	2025-09-26 13:44:43 +10:00

Chris Webb	81985d20c9	shared/runtime/mpirq: Check separate hard IRQ stack correctly. ... On the zephyr port, hard IRQ handlers run with a separate stack on a different thread, so each call to mp_irq_dispatch() and mp_irq_handler() has to be wrapped with adjustments to the stack-limit checker. Move these adjustments into the shared mp_irq_dispatch(), introducing MICROPY_STACK_SIZE_HARD_IRQ which a port can define to non-zero if it uses a separate stack for hard IRQ handlers. We only need wrap the hard dispatch case. This should reduce binary size on zephyr without affecting other ports. Signed-off-by: Chris Webb <chris@arachsys.com>	2025-09-25 23:59:24 +10:00
Chris Webb	64fd2f5f36	esp32/machine_timer: Warn that hard timers are not implemented. ... machine.Timer() has inconsistent behaviour between ports: some run callbacks in hard IRQ context whereas others schedule them like soft IRQs. Most ports now support a hard= argument to the machine.Timer constructor or initialiser to explicitly choose between these behaviours. However, esp32 does not support hardware interrupts because they are not delivered to the main thread, so the interrupt handler would need to acquire the GIL. Raise a ValueError if hard=True is requested for esp32 machine.Timer. Signed-off-by: Chris Webb <chris@arachsys.com>	2025-09-25 23:59:24 +10:00
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

As on the rp2 port, add support to the zephyr port for a hard= argument to explicitly choose between these, setting the default to False to match the existing behaviour. Adjust the stack-limit check to use the ISR stack while the callback is dispatched so that hard IRQ callbacks work, as with machine_pin.c and machine_i2c_target.c IRQ callbacks.

When reading value from ADC, ADC_ChannelConfTypeDef.SamplingTime should be specified SamplingTimeCommon1 or SamplingTimeCommon2. In this patch, SamplingTimeCommon2 is used for internal sensors and SamplingTimeCommon1 is used for external ADC channels. Signed-off-by: Yuuki NAGAO <wf.yn386@gmail.com>	2025-09-23 14:48:16 +10:00

Lines like the following were not handled by `make-stmconst.py`: #define APBPERIPH_BASE (PERIPH_BASE) This leads to missing definitions on stm module. For example, `stm.RTC` is not defined if `RTC_BASE` is defined as #define RTC_BASE (APBPERIPH_BASE + 0x00002800UL) because `APBPERIPH_BASE` is not handled as a valid id.

Mike Wang	8c389db6ea	unix/main: Ensure atexit function is called with -m <module>. ... Previously, when running `micropython -m <module>` and the module called sys.exit(), the registered atexit function was not executed. This was due to sys.exit() raising a SystemExit exception, which bypassed the atexit handler. This change fixes the issue so that the atexit function is properly invoked when exiting via sys.exit(). Additionally, following the pattern in execute_from_lexer(), mp_hal_set_interrupt_char() and mp_handle_pending() handling were added to ensure that the atexit function is also executed when the user exits via Ctrl-C.

Jeff Epler	f0c6f16b9e	all: Remove Python 2.7 support. ... Python 2.7 has been EOL since January 2020. Ubuntu oldoldlts (Focal Fossa, 20.04) has Python 3.8. Debian oldoldstable (Buster, from 2019) has Python 3.7. RHEL 8 (from 2019) has Python 3.6. It's easier than ever to install a modern Python using uv. Given this, it seems like a fine idea to drop Python 2.7 support. Even though the build is not tested on Python as old as 3.3, I left comments stating that "3.3+" is the baseline Python version. However, it might make sense to bump this to e.g., 3.10, the oldest Python 3 version used during CI. Or, using uv or another method actually test on the oldest Python interpreter that is desirable to support (uv goes back to Python 3.7 easily; in October 2025, the oldest supported Python interpreter version will be 3.10) Signed-off-by: Jeff Epler <jepler@gmail.com>	2025-09-15 14:53:32 +10:00

Angus Gratton	371db85c8e	esp32/machine_uart: Convert machine.UART objects to static instances. ... Makes machine.UART objects static instances (similar to other ports), adds machine_uart_deinit_all() function for cleanup on soft reset. - Fixes the case where the OS-level uart_event_task is leaked (along with 2KB of heap) when a UART object is garbage collected (including after a soft reset). - Fixes hard fault if a previous UART irq() fires after the UART object is garbage collected (including after a soft reset), but before any new UART object is instantiated for the same UART number. - Constructing multiple UART objects for the same UART now returns the same instance multiple times, not different instances. - Was also able to streamline deinit/init to only install the driver once, rather than install-with-defaults/uninstall/reinstall. Alternative would be to add a finaliser, but this is more consistent with how most other UART objects are implemented. This work was funded through GitHub Sponsors.
