RE: [ts-7000] relays control

[salva g <>]

Ok, i have to put
#define RELAYBASE 0xEE000000
as base, and
0x142
as offset,  but now:
the response I have in the shell is only 2 hexa characters, how can I output more than this please? because if I have more than 8 relays(in other board for example)...i could not see or modifiying them.
Thanks

Subject: [ts-7000] relays control

 

Hi I'm working with this code in order to control relay switch, (the TS-Relay8 Board) on a TS7800,

#include <netinet/in.h>
 #include <arpa/inet.h>
 #include <unistd.h>
 #include <time.h>
 #include <ctype.h>
 #include <sys/mman.h>
 #include <fcntl.h>
 
 #define RELAYBASE 0xEE000140
    
 int main() 
{
      volatile unsigned int *PBDR;
      unsigned char state; 
      unsigned char *start; 
      int fd = open("/dev/mem", O_RDWR|O_SYNC);
      start = mmap(0, getpagesize(), PROT_READ|PROT_WRITE, MAP_SHARED, fd, RELAYBASE);
      PBDR = (unsigned int *)(start + 0x02);
      state = *PBDR;
      printf("Result: %x\n",state);
      return 0;
}

Can be compiled, but return Segmentation Faults when it runs. Instead, with the shell I can do peek16 0xEE000142 with no problem.
Any ideas please?
