I'm using MP as an embedded scripting engine for my firmware. I find that when there is an error in a script that MP waits in a loop and basically hangs my firmware. Is there a way to set micropython to just exit so that my firmware can continue regardless of script issues?

I have several C structs in my firmware that need to be read and written to by both C and Python. Currently what I am doing is copying the structs into byte arrays and passing them by reference using a C callback. Is there a more efficient way of doing this?

Just one more question, in your example, how would I pass an argument(s) from python to C? ie. c_sample.call_callback(X, Y, ... )

Could I add more C callbacks without modifying mpconfigport.h? You only need to modify mpconfigport.h to add the module. Once the module has been added you can add as many methods to the module that you want by just modifying c_sample.c (or whatever you call your module). By convention, I probably ...

The function mp_obj_new_bytearray https://github.com/micropython/micropython/blob/master/py/obj.h#L605 will allocate a bytearray and populate it with the data passed in. The mp_obj_new_bytearray_by_ref will allocate a bytearray object, but it will point to the data passed in. You can see the implem...

I guess the details depend on who allocates the array (C or python). What type of data will live in the array? Python has some specialized types of arrays, like bytearray, and a more generic array of same sized items. The array will be allocated in C. It will be an array of same sized items, but a ...

I think the uctypes are what I need. I just need to pass an array that the python code will operate on. The part I don't quite understand is how do I actually define that array in C. The documentation doesn't talk about the C side of things, unless I'm completely misunderstanding something.

I am very new to MP and to Python in general. Let me start by saying that I want to use MP to execute byte code that comes precompiled using the cross platform MP compiler. I want to be able to pass a C variable into and out of that byte code. Basically all my hardware will be handled in C, mostly b...

I'm interested in building mp for the Atmel SAMV71. I've never really used gcc extensively and therefore not too familiar with how Make files are structured. I would like to know what changes do I need to make to the make file for the minimal build? Any help that you guys can provide will be appreci...
