IAR Workbench

IAR DLIB

The runtime library uses a set of low-level functions—which are referred to as the DLIB low-level I/O interface—to communicate with the target system. Most of the low-level functions have no implementation. See IAR manual C/C++ Compiler User Guide

To use some of the DLIB high-level functions, the project must implement some of the low-level functions. For example __read() and __write() in order to use for example printf() and scanf()

IAR has skeleton implementations examples in the IAR Workbench installation files. ON my PC they are in: C:\Program Files (x86)\IAR Systems\Embedded Workbench 8.5\430\src\lib\dlib

Use of printf() and scanf()

In order to use printf() and scanf() the low level functions __read() and __write() must be implemented in the project enabling writing and reading to STDOUT/STDERR and STDIN.
