QUESTION: documentation add a new c-module #263

Open ghost opened 5 years ago

ghost commented 5 years ago

I tried to add a c-module to my project but the documentation https://micropython-dev-docs.readthedocs.io/en/latest/adding-module.html does not fit.

I am still hanging on the very first step, adding a module (like esp32/mymodule.c) If I add it to the components.mk in MicroPython_BUILD/components/ the build script will tell me *** No rule to make target

There is still no code in mymodule.c !

Sincerly Felix

Here is a working example on how to create a C module on the LoBo port. If you make all the changes in the commit you should get a working "argex" module that has examples on how to expose your C code as micropython function and class methods. From there, extend the example with your code. good luck ! https://github.com/MikeTeachman/MicroPython_ESP32_psRAM_LoBo_I2S/commit/c92e00f7590b84eaf5f9818b1458c478d0b2cadf

Hey thanks a lot that helped. Will study the diff and try. (Find a nice feature of visual studio code regarding the russian comments - feels like future if the computer can translate this in an application so quickly...) Felix

Hey, I tried to include the ulab library (written for micropython) in this fork. I always get this error: error: conflicting type qualifiers for 'ulab_user_cmodule' mp_obj_module_t ulab_user_cmodule

As well as previous declaration of 'ulab_user_cmodule' was here extern const struct _mp_obj_module_t ulab_user_cmodule;

I followed the exact directions from your commit, but it still didn't help. Does anyone know what I'm doing wrong?

Hi, were you eventually able to compile ulab?
