FED PIC C Compiler Features

FED PIC C Compiler Feature Index:

• Types - the compiler supports char, int, long, and float types (integers in signed and unsigned form). double type is not supported.
• The ... form for functions is supported - but only through assembler.
• Old style "Kernigan & Ritchie" function definitions are not supported.
• Only those ANSI library routines which are relevant to typical micro-controller applications are included.

• Efficient handling of char types. As the PIC devices are 8 bit controllers, char types can be handled very efficiently. For example if x and y are global char types, then:
  
  x=0 compiles to one word
  x=y compiles to two words
  y=x++ compiles to three words
  
  
• The linker places modules in memory to minimise inter-page and long jumps.
• The FED C Compiler includes a software stack which may be used for local variables. However if it is possible, local variables are stored in temporary global memory space, the size of this area is controlled by the user. This can produce very significant savings in program execution time.
• Functions may be called using the internal call stack if call depth is 6 or less (which is very efficient), or may use the software stack which allows far deeper calling and even recursive functions.
• Wherever possible, the W register is used to hold intermediate results.

• Trigonmetric Functions - sin, cos, and tan.
• Log and Power functions - exp, log, log10, pow, pow10, and PowerSeries.
• Additional math functions - fabs, sqrt, exponent, and mantissa functions.
• Random numbers - rand, srand.
• Print to String - fPrtString.
• Constants provided - e, PI, LN2, LN10 etc...

• Asynchronous serial port handling.
• Delays & Waiting .
• LCD module handling.
• Infra Red data transfer to IRDA standards.
• Interrupt driven serial communications.
• IIC bus.
• String handling functions.
• Synchronous (clocked) serial data I/O.
• DALLAS one wire bus interface.
• Keypads.
• Maths functions (some listed above).
• Bootloader for in circuit re-programming.
• Graphic LCD drivers for T6963C device.
• stdio/stdlib/ctype standard libraries.
• printf and varieties.
• Remote control - RC5 standard protocols.

• Full editor with syntax highlighting in color. Follow your code as it steps through the editor window, view help file information directly from the code.
• Set breakpoint on line, jump to label, evaluate memory variables all by single click.
• Simulator allows addressed, conditional and timed breakpoints.
• Simulator runs up to 50 times faster than DOS based simulators and 10 times faster than some other Windows based simulators.
• Waveform Analyzer allows any register or port value to be examined in analog (graphical), waveform, or numeric values, allowing you to check your program directly against your predicted waveforms.
• Debugger allows variables to be examined in byte, word or long form, octal, decimal, hex and floating form, also dump memory areas.
• Profiler examines and times called routines - use it to optimize out bottle necks and check timing loops.
• Track errors and jump straight to error lines.
• Input stimuli include clocks, direct values and asynchronous serial data.
• Allows full use of 32 bit Windows facilities - controls and long filenames.
• Includes full terminal emulator program and support for in-circuit debugging on all devices.
