Jeff Epler	007f127a61	all: Simplify mp_int_t/mp_uint_t definition. ... Assuming proper C99 language support, we can select "the int type as big as a pointer" (most of the time) or "the 64-bit int type" (nanboxing with REPR_D), and then define everything else automatically. This simplifies port configuration files. And the types can still be overridden if needed. Signed-off-by: Jeff Epler <jepler@unpythonic.net>	2025-10-23 15:12:28 +11:00
robert-hh	3546f23143	esp32/machine_i2c: Update to support both v1 and v2 of the IDF driver. ... Support both the legacy ESP-IDF I2C driver (driver/i2c.h) and the new driver/i2c_master.h API for all ESP32-series SoCs. This is controlled by the new config option MICROPY_HW_ESP_NEW_I2C_DRIVER, which is disabled by default. There is a small change to the legacy variant, which shows now as well freq and timeout_us in the print() method. Open issues with the new driver: - No control of the stop=True|False option. stop is always assumed to be True. An issue is raised at the esp-idf repository for it. - Separate call to probe the address at fixed 100kHz. The need is caused by the fact, that NACK on an address is considered as an hard error. According to espressif's issue tracker this is already changed for v6.x and will be backported to earlier versions. So we may see it in a version after V5.5.1 or in a version 5.4.3. There is code in comments to support zero-length writes. Original patch for the v2 driver by Vincent1-python <pywei201209@163.com>.

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.

purewack	5f058e9863	esp32: Update ADC driver update to the new esp_adc API. ... This commit updates the ADC to use the new driver `esp_adc/adc_oneshot.h`. There are several errata notes about not being able to change the bit-width of the ADCs certain chips. The only chip that can switch resolution to a lower one is the normal ESP32. ESP32 C2 and S3 are stuck at 12 bits, while S2 is at 13 bits. On the S2, you can change the resolution, but it has no effect on the resolution, rather, it prevents attenuation from working at all! The resolution is set to the maximum possible for each SoC, with the ESP32 being the only one not throwing errors when trying to set the bit-width to 9, 10, 11 or 12 bits using `ADC.width(bits)`.

Alessandro Gatti	883dc41d46	esp32/main: Make the entry point function name configurable. ... This commit introduces a new port configuration entry allowing the entry point function name to be changed, from "app_main" to a custom name. This is needed when MicroPython is embedded as an ESP-IDF component, since the "app_main" symbol is already provided elsewhere, making compilation not possible. Marking MicroPython's symbol as weak would make it compile and make it possible to create and start the MicroPython task anyway with the right FreeRTOS task creation incantation, but it is probably easier to just rename the initialisation function into something else that can be accessed from outside. When MicroPython is embedded as an ESP-IDF component, the MICROPY_ESP_IDF_ENTRY definition can be set to indicate the new entry point function name. The new function name prototype should still be defined in external code to let linking succeed. Also, the NLR failure callback is marked as weak to give the chance of handling such error in a more controlled fashion rather than trigger an unconditional board restart.

The the existing logic was hard to follow, adding this config macro makes it easier to see which USB is in use and to have board definitions that enable/disable different USB levels. This commit also drops (nominal) support for manually setting CONFIG_ESP_CONSOLE_USB_CDC in sdkconfig. No included board configs use this and it didn't seem to work (if secondary console was set to the default USB Serial/JTAG then there is no serial output on any port, and if secondary console was set to None then linking fails.)

Angus Gratton	b6a3aa10f5	esp32: Remove the increased stack limit margin for ESP32-C3. ... The extra limit for C3 dates from 6823514 which added C3 support. Measuring the minimum stack margins that can pass the stress tests I measured 768 bytes for ESP32-S3 and 512 bytes for ESP32-C3 on ESP-IDF V5.2.2 and similar on V5.0.4. i.e. The ESP32-C3 actually needs less stack margin not more! I think the extra margin for ESP32-C3 probably arose from: 1. Some toolchain inefficiency in the IDF V4.x RISC-V compiler codegen, that has since been improved. OR 2. The race condition that was fixed in e3955f42 where sometimes the limit wasn't set correctly at all. This seems to trigger more on C3, presumably some timing artifact, and I'd believe that some binaries might be more susceptible than others due to random factors. OR 3.

Angus Gratton	6565b3cb34	esp32: Fix Python cstack size for bluetooth irq callbacks. ... This value should have been adjusted when the new cstack API was adopted in e3955f421d, as otherwise the stack limit is too small especially on ESP32-C3 where the stack limit was 6144 - 2048 - 2048. Some extra margin is needed for bluetooth irq because invoke_irq_handler() isn't a top-level task function, NimBLE calls through multiple layers first. Measuring this overhead on IDF V5.2.2 (by putting an abort() in invoke_irq_handler() and then measuring the stack size) yielded 672 bytes on ESP32-S3 and 612 bytes on ESP32-C3, similar to the size reported in cd66aa05cf. Sticking with 1024 bytes for added safety margin. This means on Xtensa the total margin for the BLE task stays the same (2048 bytes) as before switching to cstack.

Alessandro Gatti	0b75e180a3	esp32/mphalport: Print debug strings even before the GIL is ready. ... If verbose debugging is enabled there is some stdout output happening before the GIL is ready (for example, GC initialisation), and the code assumed that no string printing occurred before the interpreter was fully initialised. Printing long strings would operate without holding the GIL, which would crash if string output would happen too early in the startup process. This commit addresses that issue, making sure verbose debugging output will work even before the interpreter is fully initialised (as if it is not yet ready there's no GIL to take care of). Also, the threshold that would indicate whether a string is "long" (and thus requiring a GIL release/lock operation) or not was hardcoded to 20 bytes. This commit makes that configurable, maintaining 20 bytes as a default. Fixes issue #15408. Signed-off-by: Alessandro Gatti <a.gatti@frob.it>	2024-08-16 13:45:03 +10:00

Alessandro Gatti	6007f3e206	esp32/mpconfigport: Enable the RV32 emitter for ESP32C3 targets. ... The RV32 code emitter assumed that the arch-specific NLR was used instead of the setjmp/longjmp based NLR code. If the latter NLR provider was chosen, the emitter would allocate space on the stack for the NLR buffer but would not fill it in. This change turns off setjmp()-based NLR and GCREGS for the ESP32C3 target, in favour of more platform-tailored alternatives. As setjmp() NLR is now disabled by default, the RV32 emitter can be safely enabled by default as well for the target in question.

robert-hh	ee1036023e	extmod/machine_spi: Support firstbit=LSB for machine.SoftSPI. ... Being able to send data out in LSB format can be useful, and having support in the low-level driver is much better than requiring Python code to reorder the bits before sending them / after receiving them. In particular if the hardware does not support the LSB format (eg RP2040) then one needs to use the SoftSPI in LSB mode. For this change a default definition of `MICROPY_PY_MACHINE_SPI_MSB/_LSB` was added to `py/mpconfig.h`, making them available to all ports.

Damien George	cd66aa05cf	esp32: Increase NimBLE task stack size and overflow detection headroom. ... The Python BLE IRQ handler will most likely run on the NimBLE task, so its C stack must be large enough to accommodate reasonably complicated Python code (eg a few call depths). So increase this stack size. Also increase the headroom from 1024 to 2048 bytes. This is needed because (1) the esp32 architecture uses a fair amount of stack in general; and (2) by the time execution gets to setting the Python stack top via `mp_stack_set_top()` in this interlock code, about 600 bytes of stack are already used, which reduces the amount available for Python.
