Main Features

• Supports PIC18 devices in legacy mode (not extended instructions)
• Generates tight and optimized code
• Local and global variables of 1, 8, 16, 24 and 32 bits
• Floating and fixed point math up to 32 bits
• Automatic update of the bank selection bits
• Efficient reuse of local variable space
• New chip definition files can be created
• Enhanced and compact support of bit operations, including bit functions
• Math libraries including functions like sin(), log(), exp(), sqrt(), etc.
• Standard C constant data and strings in program memory (const)
• Pointer models of 8 and 16 bits, mixed sizes in same application allowed
• RAM and/or ROM pointers
• The size of single pointers can be automatically chosen by the compiler
• Inline assembly
• Generate single assembly instructions through corresponding C statements
• Integrated interrupt support
• Device configuration bits in source code (like oscillator type, code protection, etc.)

Generated files:

• Hex file: for chip programming
• Assembly file: for inspection, or input to assemblers
• List file: for inspection
• COD file: for debugging using MPLAB
• COF file: for debugging using MPLAB X
• Error file: list warnings and errors
• Function outline: for inspection of the call structure
• Variable file: for inspection of variable addresses
• Compiler output file: summary of code and RAM usage
• Preprocessor output file : for inspection of source after preprocessing

More details:

• Multiplication, division and modulo
• Structures and unions, bitfields, typedef
• Typecast
• Arrays and pointers
• Direct bit manipulation
• Many parameters in function calls
• COD file generated for debugger and MPLAB support
• Preprocessor offering macro's, conditional compilation and include files
• The generated assembly file includes symbolic names and the C source code. Many options allows the format to be adapted to suit different needs
• Binary constants: 0b01011000
• Support for ICD debugging
• Complete header file list
