@Frederic-Baumann hi sir
can u give me the gpio library of your version ?
and why i cannot compile it in C++ compiler even though i already switch it from C compiler to C++
Here's my error
$ gccmips --std=gnu++11 sm_rotate.c -I../../libnewgpio/

gccmips: warning: environment variable 'STAGING_DIR' not defined
cc1: warning: command line option '-std=gnu++11' is valid for C++/ObjC++ but not for C [enabled by default]
