I'm not aware of anybody having ported that library to micropython.

micropython already supports arbitrary precision integers, and supports 32-bit floats.

It was just a thought if it is possible to use the raspberry pi as a microcontroller, or for raspberry pi 2, to use one processor as a microcontroller and the rest as a pc. It seems like alot of people use raspberry pi to communicate with microcontrollers, so why not integrate a microcontroller dir...

Writing from the REPL should be fine. You'll want to call os.sync() to ensure the buffers actually get written. With internal flash, the writes are delayed a bit compared to using an external sdcard. Also, if you're using USB Mass Storage, then its possible for the host to completely overwrite your ...

Great, it works! :v and, how to control the rotation speed, like servo.angle(angle, speed)? The way that continuous rotation servos work, is that when they're at the midpoint (1.5msec) the the servo will be stopped (although the exact pulse width is changed by the adjustment potentiometer on the se...

The default calibration is determined here:

And this is the code which converts angle (args[1]) into a pulse width

If you're writing to files, you should probably call os.sync() to make sure that any unwritten blocks actually get written to flash.

But other than that - yeah you can just remove power.

I believe that CPython (which is what they say is running) uses reference counted memory objects, ultimately obtained from malloc. It would use the same garbage collection as regular python. grub probably even has a malloc implementation. They said no OS, but they didn't say no C runtime. And becaus...

Generally speaking, unless you really know what you're doing, the scheduler will do a better job of load balancing your 4 processors than you can can. You can run the full version of python on the raspberry pi if you like. If you want to run mciropython, then you'll need to run the unix version of m...

Thank you. I am not a bot, although since becoming a micro-computer prototyper|maker and micro software engineer sometimes I feel like one- ha! I would like to update my avatar with my standard 80x80 pixel 'me' photo, but I don't see the option to add the bitmit? Thanks I think that this should be ...

A significant portion of the cost is in the MCU itself. The cheapest board I've found with a STM32F405 on it is this one:
