Cannot use OV5642 with Arduino MRK1000

[Timmy93]

I'm trying to use Arduino MRK1000 with OV5642 ArduCAM-Mini-5MP-Plus. In order to do so I first loaded the following example: ArduCAM_Mini_5MP_OV5642_Plus_Functions

When I compile I get the same error as here: https://github.com/ArduCAM/Arduino/issues/308 So I edited the ArduCAM.h coping the setting of ESP8266:

#define MKR1000 1
#if defined(MKR1000)
	#define cbi(reg, bitmask) digitalWrite(bitmask, LOW)
	#define sbi(reg, bitmask) digitalWrite(bitmask, HIGH)
	#define pulse_high(reg, bitmask) sbi(reg, bitmask); cbi(reg, bitmask);
	#define pulse_low(reg, bitmask) cbi(reg, bitmask); sbi(reg, bitmask);
	
	#define cport(port, data) port &= data
	#define sport(port, data) port |= data
	
	#define swap(type, i, j) {type t = i; i = j; j = t;}
	
	#define fontbyte(x) cfont.font[x]  
	
	#define regtype volatile uint32_t
	#define regsize uint32_t
#endif

In this way I solved the compilation problems but the SPI does not work. The sketch give me the following error: ACK CMD SPI interface Error! and I have no idea on how to solve this problem.

This is how I connected the cam to the MKR:

CAM   ||||   MKR1000

CS             pin 7                
MOSI           pin 8 (MOSI)
MISO           pin 10 (MISO)              
SCK            pin 9 (SCK)            
GND            GND             
VCC            5V
SDA            pin 11 (SDA)
SCL            pin 12 (SCL)           

Here is the pinout of the MKR1000 (e.g. pin 7 correspond to D7):

EDIT:

I solved changing the connection of CS, now it is:

CAM   ||||   MKR1000
CS             pin 0

Now the example print me this:

ACK CMD SPI interface OK.
ACK CMD Can't find OV5642 module!

Why it can not find the module?

EDIT2: Sometimes the module is recognised and print the following message: ACK CMD OV5642 detected. And then doesn't print nothing. Now, how can I read the image?
