VC0706 and Nano Every ?

Post by DonSenilo »

Hello

I have the weather-proof VC0706 and can't get it to work with the Arduino Nano Every.
I use the Adafruit Library Example and tried every Pin-Combination I could found online regarding the VC0706.
Like this: https://learn.adafruit.com/ttl-serial-c ... uino-usage
Can someone please help me how to connect the camera to the Every ?

I use this example and tried various settings but it does not work.
But to be honest: I'm not sure how to use/establish a correct serial connection (Serial1).

Code: Select all

// This is a basic snapshot sketch using the VC0706 library.
// On start, the Arduino will find the camera and SD card and
// then snap a photo, saving it to the SD card.
// Public domain.

// If using an Arduino Mega (1280, 2560 or ADK) in conjunction
// with an SD card shield designed for conventional Arduinos
// (Uno, etc.), it's necessary to edit the library file:
//   libraries/SD/utility/Sd2Card.h
// Look for this line:
//   #define MEGA_SOFT_SPI 0
// change to:
//   #define MEGA_SOFT_SPI 1
// This is NOT required if using an SD card breakout interfaced
// directly to the SPI bus of the Mega (pins 50-53), or if using
// a non-Mega, Uno-style board.

#include <Adafruit_VC0706.h>
#include <SPI.h>
#include <SD.h>

#if defined(__AVR__) || defined(ESP8266)

// On Uno: camera TX connected to pin 2, camera RX to pin 3:
#include <SoftwareSerial.h>         
SoftwareSerial cameraconnection(2, 3);
// On Mega: camera TX connected to pin 69 (A15), camera RX to pin 3:
//SoftwareSerial cameraconnection(69, 3);

#else
// On Leonardo/M0/etc, others with hardware serial, use hardware serial!
// Using hardware serial on Mega: camera TX conn. to RX1,
// camera RX to TX1, no SoftwareSerial object is required:
#define cameraconnection Serial1

#endif

Adafruit_VC0706 cam = Adafruit_VC0706(&cameraconnection);


// SD card chip select line varies among boards/shields:
// Adafruit SD shields and modules: pin 10
// Arduino Ethernet shield: pin 4
// Sparkfun SD shield: pin 8
// Arduino Mega w/hardware SPI: pin 53
// Teensy 2.0: pin 0
// Teensy++ 2.0: pin 20
#define chipSelect 8

// Pins for camera connection are configurable.
// With the Arduino Uno, etc., most pins can be used, except for
// those already in use for the SD card (10 through 13 plus
// chipSelect, if other than pin 10).
// With the Arduino Mega, the choices are a bit more involved:
// 1) You can still use SoftwareSerial and connect the camera to
//    a variety of pins...BUT the selection is limited.  The TX
//    pin from the camera (RX on the Arduino, and the first
//    argument to SoftwareSerial()) MUST be one of: 62, 63, 64,
//    65, 66, 67, 68, or 69.  If MEGA_SOFT_SPI is set (and using
//    a conventional Arduino SD shield), pins 50, 51, 52 and 53
//    are also available.  The RX pin from the camera (TX on
//    Arduino, second argument to SoftwareSerial()) can be any
//    pin, again excepting those used by the SD card.
// 2) You can use any of the additional three hardware UARTs on
//    the Mega board (labeled as RX1/TX1, RX2/TX2, RX3,TX3),
//    but must specifically use the two pins defined by that
//    UART; they are not configurable.  In this case, pass the
//    desired Serial object (rather than a SoftwareSerial
//    object) to the VC0706 constructor.


void setup() {

  // When using hardware SPI, the SS pin MUST be set to an
  // output (even if not connected or used).  If left as a
  // floating input w/SPI on, this can cause lockuppage.
#if !defined(SOFTWARE_SPI)
#if defined(__AVR_ATmega1280__) || defined(__AVR_ATmega2560__)
  if(chipSelect != 53) pinMode(53, OUTPUT); // SS on Mega
#else
  if(chipSelect != 10) pinMode(10, OUTPUT); // SS on Uno, etc.
#endif
#endif

  Serial.begin(38400);
  Serial.println("VC0706 Camera snapshot test");
  
  // see if the card is present and can be initialized:
  if (!SD.begin(chipSelect)) {
    Serial.println("Card failed, or not present");
    // don't do anything more:
    return;
  }  
  
  // Try to locate the camera
  if (cam.begin()) {
    Serial.println("Camera Found:");
  } else {
    Serial.println("No camera found?");
    return;
  }
  // Print out the camera version information (optional)
  char *reply = cam.getVersion();
  if (reply == 0) {
    Serial.print("Failed to get version");
  } else {
    Serial.println("-----------------");
    Serial.print(reply);
    Serial.println("-----------------");
  }

  // Set the picture size - you can choose one of 640x480, 320x240 or 160x120 
  // Remember that bigger pictures take longer to transmit!
  
  cam.setImageSize(VC0706_640x480);        // biggest
  //cam.setImageSize(VC0706_320x240);        // medium
  //cam.setImageSize(VC0706_160x120);          // small

  // You can read the size back from the camera (optional, but maybe useful?)
  uint8_t imgsize = cam.getImageSize();
  Serial.print("Image size: ");

  Serial.println("Snap in 3 secs...");
  delay(3000);

    filename[6] = '0' + i%10;
    // create if does not exist, do not open existing, write, sync after write
    if (! SD.exists(filename)) {
      break;
    }
  }
  
  // Open the file for writing
  File imgFile = SD.open(filename, FILE_WRITE);

  // Get the size of the image (frame) taken  
  uint32_t jpglen = cam.frameLength();
  Serial.print("Storing ");
  Serial.print(jpglen, DEC);
  Serial.print(" byte image.");

  // Read all the data up to # bytes!
  byte wCount = 0; // For counting # of writes
  while (jpglen > 0) {
    // read 32 bytes at a time;
    uint8_t *buffer;
    uint8_t bytesToRead = min((uint32_t)32, jpglen); // change 32 to 64 for a speedup but may not work with all setups!
    buffer = cam.readPicture(bytesToRead);
    imgFile.write(buffer, bytesToRead);
    if(++wCount >= 64) { // Every 2K, give a little feedback so it doesn't appear locked up
      Serial.print('.');
      wCount = 0;
    }

Thanks, but I already know both articles.

Do you get any indication of the error in the compilation or running?

you have to figure out what the hardwareserial connection is, once you have that, it should work when wired up to those pins - can try swapping them in case you have them backwards.
if you arent sure, invest in an Arduino UNO or similar - something well known, the nano every is not as well supported as its newer and we don't own one (nor have we tested it)
