Description
This example shows an easy and common way to store a string (e.g. for the application version) and printing it out.
Source Code
#include <dev/board.h>
#include <stdio.h>
int main(void)
{
char *version = "1.0";
u_long baud = 115200;
NutRegisterDevice(&DEV_DEBUG, 0, 0);
freopen(DEV_DEBUG_NAME, "w", stdout);
_ioctl(_fileno(stdout), UART_SETSPEED, &baud);
printf("Application version: %s\n", version);
for(;;);
return 0;
} Output
Application version: 1.0
Details
defines a pointer to the type char, which points to an adress in memory where the string "1.0" is stored.
printf("Application version: %s\n", version);now prints out the string stored at the adress, the version pointer provides.
