MPLAB® C Compiler for PIC18 MCUs (C18)
No Longer Available
The MPLAB® C Compiler for PIC18 MCUs (also known as MPLAB C18) is a full-featured ANSI compliant C compiler for the PIC18 family of PICmicro® 8-bit MCUs. MPLAB C is a 32-bit Windows® console application as well as a fully integrated component of Microchip’s MPLAB Integrated Development Environment (IDE), allowing source level debugging with MPLAB’s software and hardware debug engines.
Projects, compiler switches and linker customizations can be controlled completely within MPLAB IDE to provide a full graphical front end for this powerful compiler. Text errors in source code and breakpoints instantly switch to corresponding lines in the proper file, and watch windows show data structures with defined data types, including floating point, arrays and structures.
- ANSI '89 compatibility
- Integration with the MPLAB IDE for easy-to-use project management and source-level debugging
- Generation of relocatable object modules for enhanced code reuse
- Compatibility with object modules generated by the MPASM assembler, allowing complete freedom in mixing assembly and C programming in a single project
- Transparent read/write access to external memory
- Strong support for inline assembly when total control is absolutely necessary
- Efficient code generator engine with multi-level optimization
- Extensive library support, including PWM, SPI, I2C, UART, USART, string manipulation and math libraries
- Full user-level control over data and code memory allocation
- Supports both a small (16-bit pointers) and a large (24-bit pointers) memory model for efficient use of memory
- MPLIB allows easy use of included libraries and for user created libraries
- Extensive multi-pass optimizations
- Supports new PIC18F extended mode instructions
The Standard-Eval Version is free! It has all the features of the full compiler and libraries. After 60 days, the optimizations related to procedural abstraction and to the extended instruction set of the newer PIC18XXXX devices will be disabled. Code compiled after the expiration date will function but may occupy more memory space.
