Hi Juergen,
In the FriendlyARM linux examples they show that the LEDs (IO) can be
accessed in the following manner:
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <sys/ioctl.h>
int main(int argc, char **argv)
{
int led_state = 1;
int led_no = 0;
int fd;
fd = open("/dev/leds0", 0);
if (fd < 0) {
fd = open("/dev/leds", 0);
}
if (fd < 0) {
perror("open device leds");
exit(1);
}
ioctl(fd, led_state, led_no);
close(fd);
return 0;
}
In the oselas documentation they show one can access the leds through
/sys/class/leds. How would one access the peripherals or IOs in PTXdist
using C?
Is there any example programs?
