Here is everything you need to know about the C30 compiler, from its technical roots to its modern-day relevance. What is the MPLAB C30 Compiler?

// Example: declare a large array without banking mistakes #define LARGE_BUFFER(type, name, size) type BANKED_FAR name[size]

// ------------------------------------------------------------ // 4. DSP FIXED-POINT UTILITY (C30 lacks saturating arithmetic) // ------------------------------------------------------------ #define Q15(x) ((int)((x) * 32768.0)) #define SATURATE_Q15(x) ( (x) > 32767 ? 32767 : ( (x) < -32768 ? -32768 : (x) ) )

Every C30 project requires a .gld (linker script) file. This file tells the compiler exactly how the memory map of your specific chip is laid out.
