Add C function support #13

Open jadonk opened 6 years ago

It shouldn't be required to create node modules to add C functions that are compiled on the target. Need to merge in support for C routines that leverage Arduino-for-Userspace-Linux.

Copied from original issue: jadonk/bonescript#27

jadonk commented 6 years ago

The Arduino-for-Userspace-Linux library seems to be largely superseded by MRAA and the now "native" support by create.arduino.cc.

anujdeshpande commented 6 years ago

So does first class support with MRAA help us work with create.arduino.cc?

I see that we are already supported - makes sense to add first class support? (looks like there are still things to do to get there)

jadonk commented 6 years ago

It is still riddled with bugs to the best of my knowledge, but this could increase the user base significantly.

@jadonk @anujdeshpande I have tried to implement external C function support through this example here : [https://github.com/vaishnav98/bonescript/tree/master/test/test-ffi_spi].can you please review it , i had the code tested on BeagleBone Black with Linux beaglebone 4.9.88-ti-r111 and BeagleBoard.org Debian Image 2018-03-05

I tried to implement the exported SPI functions to bonescript so that it can be called like this : var b=require('bonescript') b.openSPI(); ...

but in this case the example works only when the example.js is in the same directory as the spi.js, and throws an error "File not Found spidev.so" , it seems like a path issue how can i solve it?can it be solved by adding the path to the .so file in LD_LIBRARY_PATH environment variable, if yes , how do i modify the makefile to accomodate this?
