PDCLib: Compact ISO C99 Standard Library for Embedded Systems

A lightweight and portable C library for embedded systems, providing essential core functionality like strings, memory allocation, data structures, math functions, and input/output.

What is PDCLib?

PDCLib is a compact and portable ISO C99 standard library implementation aimed at embedded systems and other resource limited environments. It provides core C functionality like strings, dynamic memory allocation, data structures, math functions, and input/output without relying on an underlying operating system.

Some key features of PDCLib include:

  • Compact code size - The entire library is under 100KB
  • Portable - Supports many architectures and compilers
  • MIT License - Free to use in commercial applications
  • C99 compliant - Implements ISO/IEC 9899:1999 standard library
  • Extensive documentation - Well documented API and implementation

As an embedded-focused C standard library, PDCLib is ideal for use cases like microcontrollers, real-time systems, and bare-metal applications where memory and CPU resources are very limited. It gives developers access to common C functions and data structures without the overhead of a heavyweight OS-based C library implementation.
