The MPLAB-C18 compiler is a full-featured ANSI compliant C compiler for the Microchip Technology PIC18CXXX family of PICmicro® 8-bit microcontrollers (MCUs). MPLAB-C18 is fully compatible with Microchip’s MPLAB Integrated Development Environment (IDE), allowing source level debugging with both the MPLAB ICE In-Circuit Emulator and the MPLAB SIM simulator. MPLAB provides a convenient, project oriented development environment that reduces development time. MPLAB-C18 allows code for the PIC18CXXX family to be written in the C high-level language using powerful PICmicro libraries, enabling the developer to devote more time to the application and less time to the details of the processor. MPLAB-C18 was designed explicitly for the PIC18CXXX family and allows the use of a software stack for maximum RAM reusability. MPLAB-C18 provides user configurable interrupt support for saving and restoring context during interrupt handling. Libraries are provided for multiple memory models. Libraries, precompiled objects, and linker scripts can be included in MPLAB projects along with C and Assembly source files for use with MPLAB’s make and build functions. MPLAB-C18 will run on any 486 or better PC as a native 32-bit Windows® 95 or Windows NT® executable.
