Re: Building MP as a static library

Hi again, in order to use the MPY as a library, I would like to know how to use the stack and heap and what to set them to. Taking some example from the minimal port there is a heap variable being set and passed to gc_init(). With stmhal mp_stack_set_limit() is used to set the stack limit. I intend ...

Re: Micro Python development wish list

1. I currently use the internal flash to store configuration and calibration data. Now the data is being stored in a file and that is 1 to 2K in size, so the file system capacity could be reduced as you suggest. 2. It is close to what you describe. I will try to wrap something up and send you to you...

Re: Micro Python development wish list

Thank you Damien for the follow up. As I mentioned earlier, the environment you and your team have provided so far has proven to be an excellent platform to be used for prototyping and even to be used for a real application. The main issues that I have found while developing my application (now rela...

Re: Micro Python development wish list

I would like to emphasize on the importance of eliminating heap fragmentation as Damien mentioned at the beginning of this post. IMHO, this issue should be addressed as soon as possible as it is critical in running any serious application (critical or not). I was starting to initially develop an app...

STM Registers Access

Hi,
can someone provide some examples to manipulate the STM registers (with import stm)?

I would like to control the WDG and some examples would help. Thanks.

Re: Supporting zero-copy operations in MicroPython

Hi, I am interested to hear if there is any progress on that front. I am running into major memory issues trying to read sockets into blocks and manipulating the data. So far my only option is to reimplement the code in C. If someone has done any work with dealing with buffer allocations on fixed si...

Re: CC3100-Boost demo board

Bryan,
thanks for taking care of this on my behalf. I hope other developers would find this useful and provide some feedback.
I want also to mention that TI requires that the .update() function to be called periodically, so that the underlying handlers can respond properly to events.

Unstable SD Card issues

I am having some unstable and very unusual SD Card access issues from Windows 7 (running in VMWARE on a MAC host). I used to be update scripts from W7 onto the SD Card no problem, and rarely hit any issues. Lately (I guess a few weeks ago after some MP firmware updates), I ran into issues updating. ...

Array module does not support float

Hi,
the array module does not support float on the STMHAL platform even though the code ./py/binary.c had some partial support.
just FYI.
