Combining two projects

No it did not help. That's strange however, because that's how I got it to work. I can resend a zip file without the module_FatFs module if you would like?

Hmm, which version of the tools are you using for this btw?

[tomshannon]

I am using version Community_14.1.1

by the way here is a zipped folder without module_FatFs on the top level. However for some reason, it would only read in the ""ff.h" files on my version when I had it at the top level... Which is quite strange.

Hi Tom,

I've been attempting to build this with the 14.1.2 tools.

When I run xmake in the AN00177_startKIT_adc_demo directory from the adc_task1.zip I get:

$xmake
xmake[1]: *** adc_task1/module_FatFs: Is a directory. Stop.
xmake: *** [check_modules_msg] Error 2

Removing the adc_task1/module_FatFs directory (to leave just the copy of module_FatFs within sc_sdcard) results in the tools downloading lib_startkit_support, and then the build failing with missing include files:

$xmake

Given these build issues I've gone back to the source in the data_collection.zip you attached earlier, and removed module_FatFs from the top level. I was seeing some strange build issues until I ran "xmake clean", but not the "Error: Undefined reference to '_Sadc_task_0'" you reported.

Once I got it to compile, the tools were unable to create a binary as SDCardHostSPI.xc contained recursion... I have just forked sc_sdcard (https://github.com/samchesney/sc_sdcard) and pushed a quick fix there for you, see https://github.com/samchesney/sc_sdcard ... a6a9ab8849. With this change I was able to build a binary successfully:

It might be worth checkout some of the other forks of sc_sdcard too, as it looks like some people have done a fair amount of work on it, but not opened pull requests to get it back into the main line unfortunately. Have a look at https://github.com/xcore/sc_sdcard/network and https://github.com/xcore/sc_sdcard/network/members for the other forks available.

I hope this helps you progress your project.
Cheers,
Sam
