simple/simple.c
This sample is the most simple application that could be build with Nut/OS. It doesn't do anything but running in a loop.
Only a minimal Nut/OS kernel with thread, timer and memory management is loaded, occupying less than 4 kBytes of code space and about 50 bytes of RAM.
#include <compiler.h>
int main(void)
{
for (;;);
}
