Re: MicroPython on USR-C322 (CC3200)

I use similar modules - I think they are exactly the same from HW point of view. (e.g. http://www.alibaba.com/product-detail/CC3200-wifi-Module_60205166974.html?spm=a2700.7724838.0.0.jylGWm) Some pictures here: http://forum.micropython.org/viewtopic.php?f=5&t=966&p=11503&hilit=3d+printer...

JSON string vs bytearray

What is the best approach when attempting to construct JSON string repeatedly in every cycle of main loop in case one wants to avoid memory allocation in every cycle? Could formatted string be somehow directly stored in pre-allocated bytearray? The JSON string always contains same keys, but lenght(n...

Re: Cross compiled module vs class inheritance

Thank you for your answers. I am working with CC3200 so unfortunately I cannot use frozen bytecode from flash. But it is good to know it works also in this case. I am using this approach for several days and there were no issues directly related to inheriting classes from cross-compiled modules. @py...

Remove imported module from RAM

Is there any way how to remove imported module from RAM?

E.g. - it would make sense for untplib/NTPClient which is usually required to be used only once during boot process.

Class instantiated as an object can be deleted from RAM by "del" method?

I just found out that this Moto Mod devkit for Lenovo Moto Z smartphones uses L476:

What changes needs to be done to your port to make it running on that devkit?

Cross compiled module vs class inheritance

I am developing HVAC device controller board based on CC3200. Because of limited RAM resources I had to put most of the code into cross-compiled module containing one class which I instantiate in main.py and call function with main loop. Because of the fact that uploading .py files to Linux server, ...

Re: RFC: Moving forward with the WiPy/CC3200 port

I would also like to clarify which CC3200 service pack will be used during testing? Latest one is 1.0.1.6-2.7.0.0 (http://processors.wiki.ti.com/index.php/CC32xx_Release_Notes) while flash instructions for CC3200 port on GitHub still mention 1.0.0.10.0 (https://github.com/micropython/micropython/tre...
