1. Unzip DIGCAM.zip. You'll find 4 sub-directories: Design_1, Design_2, Design_3, and SYS_LEVEL. We will work on the source code in SYS_LEVEL/sw for PA1.
2. DIGCAM/SYS_LEVEL/ contains 6 .c files and 5 .h files. Depending on your compiler, you need to find a way to compile them and be able to run it as an executable.
3. Draw a flow diagram to represent the logic relationship between all functions. Add a new function called "scale" and implement it in c.
