comparison projects/basic/render.cpp @ 56:3c3a1357657d newapi

Further API update to name three primary functions setup(), render() and cleanup(). Changed include paths so now can #include <BeagleRT.h>. Removed stale pru_rtaudio.bin file as this is now done as pru_rtaudio_bin.h. Updated examples to new API and fixed minor compiler warnings along the way. Network example needs further attention to compile.
