[ts-7000] ts-7800 dio

["rahulsunshine" <>]

Hello,
              I am quite new to ts7800 , I have to configure dio pins,actually I want digital data from dio pins , I have to feed this digital data to my device,but when I running the code tempSensor.c  & spi.c (given in manual ) then every time I am getting the same value for raw temp i.e. ffoo on terminal , & on dio header pins I am getting all pins 3.3 except pin 10 on which I got 0v.

code:
#include<unistd.h>

#include<sys/mman.h>

#include<fcntl.h>

#include<stdio.h>

#include<stdlib.h>



#include "spi.c"
