Re: [ts-7000] Dobts about ts-dio24

I haven't tried it, but you should be able to..  On one dio24, set JP1 and JP2 both to off.  On the second dio24 set JP1 to on, and JP2 to off. Stack them on the board.

Then access the first dio24 at 0x11E00100
and the secound at 0x11E00108

I would just mmap 0x11E00000, and then access both boards by defining 2 different base addresses.

DIO24_BASE0 = 0x0100
DIO24_BASE1 = 0x0108

Then just use your mmap pointer plus your base DIO24_BASE to access which ever board you need.

Hope this helps,
Justin

Here are some snippets from what I use for my one board, much of this code came from help from others on this group:

//PC/104 8 bit read/write to I/O
static volatile unsigned char *pc104_start;
static volatile unsigned char *dio24_r0_Identifier;
static volatile unsigned char *dio24_r1_Reserved;
static volatile unsigned char *dio24_r2_JumperStatus;
static volatile unsigned char *dio24_r3_InteruptControl;
static volatile unsigned char *dio24_r4_DDR;
static volatile unsigned char *dio24_r5_DRA;
static volatile unsigned char *dio24_r6_DRB;
static volatile unsigned char *dio24_r7_DRC;
static int fd;

//Pick the correct base depending on jumper settings
#define DIO24_BASE (0x0100) //jp1 and jp2 off
//#define DIO24_BASE (0x0108) //jp1 on and jp2 off
//#define DIO24_BASE (0x0110)
//#define DIO24_BASE (0x0118)
  fd = open("/dev/mem", O_RDWR|O_SYNC);
  if (fd == -1)
  {
    perror("open /dev/mem");
    exit(1);
  }

  int size = getpagesize();
  //printf("Page Size = %d\n", size);

  pc104_start = mmap(0, size, PROT_READ|PROT_WRITE, MAP_SHARED, fd, 0x11E00000);

  if (pc104_start == MAP_FAILED)
  {
    perror("mmap");
    exit(1);
  }

  // Assign the addresses for all of the registers
  dio24_r0_Identifier = (unsigned char *) (pc104_start + DIO24_BASE + 0);
  //dio24_r1_Reserved = (unsigned char *) (pc104_start + DIO24_BASE + 1);
  //dio24_r2_JumperStatus = (unsigned char *) (pc104_start + DIO24_BASE + 2);
  //dio24_r3_InteruptControl = (unsigned char *) (pc104_start + DIO24_BASE + 3);
  dio24_r4_DDR = (unsigned char *) (pc104_start + DIO24_BASE + 4);
  //dio24_r5_DRA = (unsigned char *) (pc104_start + DIO24_BASE + 5);
  dio24_r6_DRB = (unsigned char *) (pc104_start + DIO24_BASE + 6);
  //dio24_r7_DRC = (unsigned char *) (pc104_start + DIO24_BASE + 7);

Hi all...

Anybody knows if is possible to connect 2 ts-dio24 to a ts-7000 board?

If is possible, how to do it?

thx
