CCS C Programming and Features

CCS Compiler Features

• Integral syntax-aware editor enhances coding efficiency and accuracy.
• CCS C extends standard C by incorporating limited support for reference parameters in functions.

PIC-specific Pre-processor Directives

• Directives unique to PIC alongside standard ones include:
  • #inline: Allows the implementation of functions inline for performance optimization.
  • #priority: Sets the priority level of interrupts, crucial for real-time applications.

Additional Functions for PIC Hardware

• output_low(): Directly sets a specific I/O port bit to a low state, useful for controlling hardware elements.
• delay_us(): Provides delays in microseconds, allowing for precise timing in embedded systems.

Boolean Variables in CCS C

• In CCS C, short int serves as an effective representation for boolean variables.
• Utilizing pre-defined macros enhances code readability and clarity.
• Definitions available in device definition files include:
  • #define boolean short int for boolean type.
  • #define false 0 to denote false value.
  • #define true 1 to denote true value.
• Boolean variables can be declared simply, e.g., boolean finished = true;.
• Standard boolean operators such as || (logical OR), && (logical AND), and ! (logical NOT) are applicable with these boolean variables.
