Errr... I inadvertently tried this under Micropython 1.8.6. Sory for wasting your time. As an example of what can be done: >>> @micropython.asm_xtensa ... def a(a2, a3): ... mov(a4, a2) ... movi(a2, 0) ... movi(a5, 1) ... label(LOOP) ... add(a2, a2, a4) ... sub(a3, a3, a5) ... bnez(a3, LOOP) >>> a(1...

As documented in the changelog (https://github.com/micropython/micropython/releases) of release 1.8.7, we have a native assembler emitter. https://github.com/micropython/micropython/commit/f76b1bfa9f59fcfa03837c6934ad51d2db3ff4a3 shows it as "@micropython.asm_xtensa". I don't see any kind of documen...

Would be nice if MQTT library included a timeout value. I do monkey patching: This code implements a 5 seconds timeout. Somebody should do a pull request for micropython-lib... Thank you for your answer. However, it may seems dumb to you as I'm just a beginner, but I thought that the problem was th...

Would be nice if MQTT library included a timeout value. I do monkey patching: class timeout_socket(umqtt.simple.socket.socket): def __init__(self): super().__init__() self.settimeout(5) def setblocking(self, flag): # "setblocking()" está documentado como # variantes de "settimeout()". # https://docs...

There exists a "machine.WDT" class in ESP8266 micropython, as documented in https://docs.micropython.org/en/latest/esp8266/library/machine.WDT.html#machine.WDT , but it is raising an exception. It seems not usable: ``` >>> a=machine.WDT(timeout=5) Traceback (most recent call last): File "<stdin>", l...

My project (running on an ESP8266) downloads the last version of the code from the web, at every boot. I would like very much to be able to "import" that code without touching the flash filesystem, possibly from memory. Is that possible?. Any idea?. PS: My current approach is to store the new module...

I would store the size of the reserved area for native code, location and size of the fat FS, spare area (to directly read/delete flash for raw access), OTA area, etc. Kind of a partition table. I would like to have a fat filesystem, but for some applications a "raw" flash area is very convenient. I...

Thanks, Roberthh. That is valuable. What would you think about storing metadata in the last area (before the SDK area) of the flash describing reservations and FAT layout?. In this way we could change sizes with a method call instead of recompiling and flashing a new image. As I understand, flashing...

Roberthh, do you have a link to the thread about persistent flash storage of native code? I am not able to find anything relevant.

Thanks a lot.

Robert, great answer. Very useful. This should documented somewhere. Using Google I found this useful discussion https://github.com/micropython/micropython/issues/2735 describing the feature. Great. But this should be documented SOMEWHERE in the official docs. "esp.flash_user_start()" is NOT documen...
