annotate projects/heavy/hello-world/SignalSamphold.c @ 160:5bcf04234f80 heavy-updated

- added -std=c99 to Makefile for user-supplied C files (required for heavy files)
- changed heavy core render.cpp file to use latest API and removed all redundant functions (e.g. foleyDesigner/touchkey stuff)
- use build_pd.sh to compile and run pd files (-h for usage instructions)
