[ts-7000] Lost with TS-ADC16

["Marcos" <>]

Guys, I am really lost with the TS-ADC16.. after fighting with this board the 
whole week, I couldn't get the board working.... I wrote a short code in order 
to test the ADC but couldn't get any coherent sample... My TS-ADC16 is working 
with a TS-7200, just that... Please, I will really appreciate some help..
The code I am running, using the provided tsadclib1624.c and tsadclib1624.h is:


#include <sys/types.h>
#include <sys/time.h>
#include <netinet/in.h>
#include <stdio.h>
# include "tsadclib1624.h"

#define NCANALES 6
#define RANGO_DAC DACRANGE_02VB  
#define RANGO_ADC ADCRANGE_0010S 
#define TBUFFER 10000
#define SAMPLINGRATE 200
#define NUMMUESTRAS 1 

int main ( )
{       
        int16_t *Buffer_Muestras[NCANALES];
        int8_t    J,index;
        int16_t TV_IMin = 0xffff;
        int16_t *aBuffer;

        for (index = 0; index < NCANALES; index++)
         {
                        if ((aBuffer = malloc(TBUFFER+1)) == NULL) {
                        printf("Error malloc\n");
                        return ;
                }
                        Buffer_Muestras[index] = aBuffer;
                }

                printf ( "\n\nInitialized: %s\n  ",!tsadclib1624_init 
(SBC_TS7200,NCANALES, TBUFFER)?"OK":"NOT OK");
                if ( index=tsadclib1624_boardstatus (0) == 0x3e ) printf ( "    
TS Board: TS-16\n");
                printf ( "Buffer: %s\n  ",tsadclib1624_buffers? "OK":"ERROR");

                index =tsadclib16_dacset ( 0, 0, RANGO_DAC, TV_IMin );          
        

                do  {
                usleep ( 500000 );
                tsadclib1624_sample ( 0, NCANALES, SAMPLINGRATE, NUMMUESTRAS, 
RANGO_ADC, Buffer_Muestras, true );
                tsadclib1624_pollResults ( 0, true );
                for ( J=0; J<=NCANALES;J++) printf ( "%d  ", Buffer_Muestras[J] 
);
                printf("\n");
            } while ( 1 );
}

Then my output is:

Initialized: OK
TS Board: TS-16
Buffer: OK
.80528  90536  100544  110552  120560  130568  0
.80528  90536  100544  110552  120560  130568  0
.80528  90536  100544  110552  120560  130568  0
.80528  90536  100544  110552  120560  130568  0
.80528  90536  100544  110552  120560  130568  0
.80528  90536  100544  110552  120560  130568  0
.80528  90536  100544  110552  120560  130568  0
.80528  90536  100544  110552  120560  130568  0
.80528  90536  100544  110552  120560  130568  0
.80528  90536  100544  110552  120560  130568  0
.80528  90536  100544  110552  120560  130568  0

As you see, the data does not have sense.. in fact, the count difference 
between channel 1 vs channel 0 = 10008
channel 2 - channel 1 = 10008, and so..

BTW, I have 0V in all ADC channels.... any idea about what the problem is?

Thanks in advance,

Marcos
