stdiodemo(3avr) on Linux
The text c985b16a2f87, as Debian 9 (Stretch) shipped it.
Using the standard IO facilitiesThis project illustrates how to use the standard IO facilities (stdio) provided by this library. It assumes a basic knowledge of how the stdio subsystem is used in standard C applications, and concentrates on the differences in this library's implementation that mainly result from the differences of the microcontroller environment, compared to a hosted environment of a standard computer. This demo is meant to supplement the documentation, not to replace it.
