[ts-7000] TS-7400 DIO

[Rodrigo Gómez <>]

Hello everybody

Have some of you accessed at DIOs 16 and 17 in the 7400?

I tried to acces to memory map, but the program returned "segmentation
fault"
I just tried the address in the manual:
"0x1200_0001: GPIO direction/data for DIO_16 to DIO_19
  bit 3:0 - data register 
  bit 7:4 - data direction register ('1' means 'output')"

My code is:
#include <sys/mman.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <unistd.h>

int main(int argc, char *argv[])
{
  int fd = open("/dev/mem", O_RDWR|O_SYNC);
  int ledPrender;
  unsigned char *control;
control = (char *)mmap(0, 4096, PROT_READ|PROT_WRITE, MAP_SHARED, fd,
0x12000001);
control[0] = 0xF0;
control[0] = 1;
}
I'm runnig with root permisions over debian running in a USB memory
Any help would be great!
Thanks 
rgo
