Arducam 0v5642 host v2 com open fail

bakanium · February 6, 2024, 7:18pm

I was trying to run Arducam mini 5MP OV5642 PLUS with Arduino Uno on the serial monitor, everything seems ok but on the host v2 it shows COM open fail.

Here's the code:

// ArduCAM Mini demo (C)2017 Lee
// Web: http://www.ArduCAM.com
// This program is a demo of how to use most of the functions
// of the library with ArduCAM Mini camera, and can run on any Arduino platform.
// This demo was made for ArduCAM_Mini_5MP_Plus.
// It needs to be used in combination with PC software.
// It can test OV5642 functions.
//

// This program requires the ArduCAM V4.0.0 (or later) library and ArduCAM_Mini_5MP_Plus
// and use Arduino IDE 1.6.8 compiler or above
#include <Wire.h>
#include <ArduCAM.h>
#include <SPI.h>
#include "memorysaver.h"
//This demo can only work on OV5642_MINI_5MP_Plus  platform.
//#if !(defined OV5642_MINI_5MP_PLUS)
//  #error Please select the hardware platform and camera module in the ../libraries/ArduCAM/memorysaver.h file
//#endif
