As I mentioned in answer to PM, There is C code for Arduino, which is much more up to date than my earlier C code for Arc32/BB2. I don’t know much about Raspberry Pi, but my assumption is the C for it will be reasonably close to the Arduino/GCC code in my other posts. If it were me, my first step would be simple program to connect the SSC-32 to your processor and get it to do simple things like move one servo back and forth…
