Hello everyone, i read a lot of topyc but my problem is still there,
I use an arduino UNO with Ethernet shield 2 and i use an 8Mo sd card. I connect my arducam with the classic connection like in the image.
and here is the arducam exemple i use (i just change the SD_CS at 4 bc of the sheild)
// ArduCAM Mini demo (C)2017 Lee
// Web: http://www.ArduCAM.com
// This program is a demo of how to use the enhanced functions
// This demo was made for ArduCAM_Mini_5MP_Plus.
// It can continue shooting and store it into the SD card in JPEG format
// The demo sketch will do the following tasks
// 1. Set the camera to JPEG output mode.
// 2. Capture a JPEG photo and buffer the image to FIFO
// 3.Write the picture data to the SD card
// 5.close the file
//You can change the FRAMES_NUM count to change the number of the picture.
//IF the FRAMES_NUM is 0X00, take one photos
//IF the FRAMES_NUM is 0X01, take two photos
//IF the FRAMES_NUM is 0X02, take three photos
//IF the FRAMES_NUM is 0X03, take four photos
//IF the FRAMES_NUM is 0X04, take five photos
//IF the FRAMES_NUM is 0X05, take six photos
//IF the FRAMES_NUM is 0X06, take seven photos
//IF the FRAMES_NUM is 0XFF, continue shooting until the FIFO is full
//You can see the picture in the SD card.
// 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

I hope someone could know how to fix my issues
Have great day
