Hi all,
I'm Alba and this is my first Post,
sorry if I'm asking something old but I couldn't find the
answer so far.
Im using a ts 7200
I need a example code (C) in order to move the DIO pins.
I tried to use this but its not working
#include <stdio.h>
#include <stdlib.h>
#include <pthread.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <sys/mman.h>
#include <unistd.h>
#include "print.h"
static int ThreadID;
static void *Thread(void);
int main (void)
{
GEN_DBG_PRT_DEBUG_FL("Main is starting");
if (pthread_create(&ThreadID, NULL, Thread, NULL)!= 0)
{
GEN_DBG_PRT_DEBUG_FL("pthread_create return error");
}
while(1) sleep(1000);
return 0;
}
static void *Thread(void)
{
GEN_DBG_PRT_DEBUG_FL("Thread is starting\n");
fflush(NULL);
volatile unsigned int *PEDR, *PEDDR, *PBDR, *PBDDR, *GPIOBDB;
unsigned char *start;
int fd = open("/dev/mem", O_RDWR);
// TRACE(printf("DIO_SETUP()\n"));
start = mmap(0, getpagesize(), PROT_READ|PROT_WRITE, MAP_SHARED, fd, 0x80840000);
// DIO registers
PBDR = (unsigned int *)(start + 0x04); // port b
PBDDR = (unsigned int *)(start + 0x14); // port b direction register
PEDR = (unsigned int *)(start + 0x20); // port e data
PEDDR = (unsigned int *)(start + 0x24); // port e direction register
GPIOBDB = (unsigned int *)(start + 0xC4); // debounce on port b
GEN_DBG_PRT_DEBUG_FL("ok1\n");
fflush(NULL);
*PBDDR =0xFF;
*PBDR=0x01; // upper nibble output,
*GPIOBDB = 0x01; // enable debounce on bit 0
GEN_DBG_PRT_DEBUG_FL("ok2\n");
fflush(NULL);
// *PEDDR = 255; // all output (just 2 bits)
close(fd);
//}
}
Thanks in advance.
