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?

@Timmy93 Hi, Great to hear you have compiled the code on Arduino MRK1000 platform. Our library hasn't added this platform support.If you can work fine by adding it. Welcome to optimize our code library. The ArduCAM_Mini_5MP_OV5642_Plus_Functions is used with Arducam Host_V2 app. Please refer to this video demo to get more detail information. https://www.youtube.com/watch?v=hybQpjwJ4aA&feature=youtu.be

@UCTRONICS Thank you for your answer. Currently I'm making a thesis project and I should read the image and send it to a server through a POST request. Is it possible to read directly the image and send it without using third party software?

@Timmy93

About post server, which is not our mainly business. You can refer to our Arducam ESP8266 demos from https://github.com/ArduCAM/ArduCAM_ESP8266_UNO/blob/master/libraries/ArduCAM/examples/examples/ESP8266/ArduCAM_ESP8266_UNO_Capture/ArduCAM_ESP8266_UNO_Capture.ino This demo's mainly work is that the image data will send to web client directly when you visit the 8266 server by your browser.

Hello - I am also trying to get an ArduCAM (in my case, the ArduCAM Mini 2 MP OV2640) to work with an Arduino MKR device. In my case, it is an Arduino MKRWAN 1300 (but I believe the board is substantially the same as the MKR1000).

However, I am curious why you decided to duplicate the definitions from ESP8266 in ArduCAM.H? Why did you choose that instead of duplicating the settings for ARDUINO_SAMD_ZERO? The ESP8266 has a different type of CPU than the MKR1000, right?

Incidentally, I tried what you had suggested (copying the settings from ESP8266) but it causes the board to hang after a reset. Then I have to double-reset it to get back to the bootloader in order to recover it.

Thank you for any insight you can share.

We have tried running the mini ov5642 plus 5mp with the arduino uno r3. We wired them as instructed and the code gets uploaded swiftly, but the com in the host app does not open. What could be the problem?

Hey guys, did anyone manage to get this working? I'm having the same trouble on my WAN 1310 board.
