The Byte Craft MPC C compiler supports the Microchip PIC 12/14/16/17 microcontroller families, including 8K and flash parts.

Operating System Support

• Windows

The MPC Code Development System includes:

• an optimizing PIC C-Compiler.
• the BCLink linker.
• an Integrated Development Environment and editor.
• a built-in PIC macro cross-assembler.

PIC C Compiler Features In Detail

• part-specific header files describe the unique features of each PIC target device.
• compiler configuration using #pragma directives.
• PIC ports are declared and protected using the #pragma port series of directives
• the #pragma vector directive specifies the location and assigned name for PIC interrupt sources.
• BClink Linker links object files and libraries compiled with the PIC C-compiler mpc.exe
• PIC object libraries can be included directly in C source files using Absolute Code Mode
• named address spaces support the grouping of variables at specific memory locations
• SPECIAL address space declares variables at special locations such as external devices or internal EPROM
• LOCAL address space allows you to use local variables
• extensions to the C language designed specifically for the PIC embedded systems developer. Some extensions include bit-sized data types, binary constants, extended case statements, direct variable placement with the @ symbol, and support for processor-specific functions.
• interrupt handler support in C; makes context saving and restoring easy.
• data types include:
• _Bool, bits
• char, short, int, long
• float, float24, float32
• int8, int16, int24, int32 (unambiguous ints)
• C99 unambiguous data types: uintx_t, intx_t
• register-oriented types for direct access to processor registers when necessary
• selectable 8- or 16-bit int data type.
• packed bit fields in structs.
• include single and multiple lines of inline assembly within a C program with the #asm and #endasm directives
• extensive control over computer-generated initialization.
• generates source-level information required for PIC emulators.
• support for transparent PIC data bank switching
• support for PIC program memory page switching
• can call a function located anywhere in memory in the PIC 12-bit core, not just in the bottom half of the memory page
• support for PIC hardware registers, including setting configuration fuses
• PIC libraries including:
• math libraries for all PICmicro families
• delays for PIC16C5x and PIC16cxx
• asynchronous serial routines for PIC16C73/74 and PIC17cxx
• 4- and 8-channel A/D
• EEPROM access routines
• optional 32-bit result of 16 x 16 multiply
• use with Microchip MPLAB
• source-level debugging with Microchip's PICMASTER emulator system, ICE 2000 emulator, MPLAB-SIM simulator system, Advanced Transdata, Tech-Tools Mathias Clearview
