Bonjour je m’appelle Lisa , je suis en terminale sti2d et j’ai pour projet de faire une application pour commander un robot et sur le robot il y aura une camera et je cherche à faire fonctionner la camera avec l’application et il faudrait que la vidéo de la camera s’affiche sur l’application et je ne sais pas comment relier les deux.
Merci de votre compréhension.
j’utilise une camera serial grove 101020000 et un arduino uno
it’s my program in arduino :
#include <SPI.h>
#include <arduino.h>
#include <SD.h>
#define PIC_PKT_LEN 128 //data length of each read, dont set this too big because ram is limited
#define PIC_FMT_VGA 7
#define PIC_FMT_CIF 5
#define PIC_FMT_OCIF 3
#define CAM_ADDR 0
#define CAM_SERIAL Serial
#define PIC_FMT PIC_FMT_VGA
File myFile;
const byte cameraAddr = (CAM_ADDR << 5); // addr
const int buttonPin = A5; // the number of the pushbutton pin
unsigned long picTotalLen = 0; // picture length
int picNameNum = 0;
/*********************************************************************/
void setup()
{
Serial.begin(115200);
pinMode(buttonPin, INPUT); // initialize the pushbutton pin as an input
Serial.println(“Initializing SD card…”);
pinMode(10,OUTPUT); // CS pin of SD Card Shield
if (!SD.begin(10))
{
Serial.print("sd init failed");
return;
}
Serial.println("sd init done.");
initialize();
}
//
void loop()
{
int n = 0;
while(1){
Serial.println("\r\nPress the button to take a picture");
while (digitalRead(buttonPin) == LOW); //wait for buttonPin status to HIGH
if(digitalRead(buttonPin) == HIGH){
delay(20); //Debounce
if (digitalRead(buttonPin) == HIGH)
{
Serial.println("\r\nbegin to take picture");
delay(200);
if (n == 0) preCapture();

GetData();
}

Hello my name is Lisa, I am in sti2d terminal and I plan to make an application to control a robot and on the robot there will be a camera and I am trying to make the camera work with the application and it would be necessary that the video from the camera is displayed on the application and I don’t know how to link the two.
And I use a 101020000 serial grove camera and an arduino uno
Thank you for your understanding.
Similar posts show that others are attempting similar things using arduino-camera-AI2 Lisana. In case you have not found them here they are:
and
and this arduino/grove project
A method suggested is to stream the video from the arduino/camera to a Web page (on your server ??) and use the AI2 to access the Web page.
Regards,
Steve
