OVERVIEW  

This integrated C development environment gives developers the capability to quickly produce very efficient code from an easily maintainable high level language.

The compiler includes built-in functions to access the PIC hardware such as READ_ADC to read a value from the A/D converter. Discrete I/O is handled by describing the port characteristics in a PRAGMA. Functions such as INPUT and OUTPUT_HIGH will properly maintain the tri-state registers. Variables including structures may be directly mapped to memory such as I/O ports to best represent the hardware structure in C.

The microcontroller clock speed may be specified in a PRAGMA to permit built in functions to delay for a given number of microseconds or milliseconds. Serial I/O functions allow standard functions such as GETC and PRINTF to be used for RS-232 like I/O.

 Code Sample
The following code segment generates a 1kHz pulse on Port B0:

  while (TRUE) {
    output_high(PIN_B0);
    delay_us(500);
    output_low(PIN_B0);
    delay_us(500);
  }

The hardware serial transceiver is used for applicable parts when possible. For all other cases a software serial transceiver is generated by the compiler. The standard C operators and the special built in functions are optimized to produce very efficient code for the bit and I/O functions.

Functions may be implemented inline or separate, allowing to optimize for either ROM concerns or speed concerns. Function parameters are passed in reusable registers. Inline functions with reference parameters are implemented efficiently with no memory overhead.

During the linking process the program structure, including the call tree, is analyzed. Functions that call one another frequently are grouped together in the same page segment. Calls across pages are handled automatically by the tool transparent to the user. Functions may be implemented inline or separate. RAM is allocated efficiently by using the call tree to determine how locations can be re-used. Constant strings and tables are saved in the device ROM.

The output hex and debug files are select-able and compatible with popular emulators and programmers including MPLAB for source level debugging. PCW includes a powerful Windows IDE. The compiler requires Windows 95, 98, ME, NT4, 2000 or XP.

      FEATURES

  • Access to hardware features from easy to use C functions, Timers, A/D, EEPROM, SSP, PSP, I2C and more.
  • Efficient function implementation allows call trees deeper than the hardware stack.
  • Inline procedures supported to save stack space; Linker will automatically determine the best architecture or it can be manually specified.
  • Efficient function implementation allows call trees deeper than the hardware stack.
  • Automatic linking to handle multiple code pages
  • Supports 1, 8 and 16 bit integer types and 32 bit floating point variables & arithmetic. One bit type (Short Int) permits the compiler to generate very efficient Bit oriented code.
  • Compiler directives determine if tri-state registers are refreshed on ever I/O or if the I/O is as fast as possible.
  • Constants (including strings and arrays) are saved in program memory.
  • #BIT and #BYTE will allow C variables to be placed at absolute addresses to map registers to C variables.
  • Integrates with MPLAB and other simulators/emulators for source level debugging & Produces standard HEX output for use with all programmers
  • Assembly code may be inserted anywhere in the source and may reference C variables
  • Constants (including strings and arrays) are saved in program memory
  • Special windows show the RAM memory map, C/Assembly listing, and the calling tree
  • Interrupt functions supported on PCM/PCH. The compiler generates all startup and clean up code as well as identifying the correct interrupt function to be called.
  • Updates via the web for 30 days included
