Thanks, jimmo.

Does anyone know how much speedup I can expect when using viper and native emitters w.r.t. pure Python for integer and string
operations?

Hi, This is for the BLACK_F407VE STM32F407VET6 board with MicroPython 1.11 (source at top of the tree). I have used the @micropython.native decorator on the class methods that I have put in the ports/stm32/modules/ directory. On trying a clean build, I encounter this error: GEN build-BLACK_F407VE/fr...

Hi, I am redefining int() and float() for my number-like class (simplified floatoverload class below), but I get a TypeError when trying to use float(). I am returning a floating point number from __float__ ( ). int( ) works fine. Any pointers on what might would be much appreciated. I am using: Mic...

Worked. Thanks so much!

Hi, I am trying to port the mpmath package to MicroPython; the target will be Rasp-Pi-2, but I am now developing on using the Windows port. I got a little further than the OP in this post: https://forum.micropython.org/viewtopic.php?t=3621 but have now hit a roadblock with this error: D:/RPi/python>...

Perfect. Your sys.path explanation makes sense, because that's how "Mega" Python works
too, but I would have expected the /null/ path to be appended to sys.path by default in
MicroPython.

Thanks very much!

Hi, I am trying to freeze an MP module as described here: https://docs.micropython.org/en/latest/reference/constrained.html?highlight=frozen When I load the module from the MP prompt, the module is loaded correctly, but when I try to execute a file main.py that imports the frozen module, I see: # ./...

There's a low level RPi C library at http://www.airspayce.com/mikem/bcm2835/index.html I could not find anything like the Python RPi.GPIO modules so I am trying to get a MicroPython wrapper working on top of this: https://github.com/hacksterous/micropython/tree/master/ports/unix/mpbcm2835 I have tes...

Hi,

Does anyone know how to build the 'machine' module on a Raspberry Pi running Raspbian or Buildroot?
I know boochow has a bare metal version with SPI and I2C, but I need MicroPython to run inside Buildroot.

Thanks

Thanks.

Is there a MicroPython way to catch the exception (OSError in this case?)?
I would much like a more graceful exit than a soft reset.
