Sensor not showing negative axis movement when used with esp8266

I tried your code with Arduino it works fine but for some reason on esp8266 it do not show negative axis values. 
these are ESP pins
`#define PIN_SS        15
#define PIN_MISO      12
#define PIN_MOSI      13
#define PIN_SCK       14

#define PIN_MOUSECAM_RESET     5
#define PIN_MOUSECAM_CS        4`
