Hello,

1. Connecting a TTL serial camera to Arduino and saving pictures to a micro SD Here we have the schema, with the connections of the micro SD card with the TTL serial camera; I use a camera model from Adafruit.
2. That's usually how most serial projects work, and the first thing you check when a serial port doesn't work. It sounds like you connected the camera serial ports to the arduino, so your sketch should set up a serial port at 38400 baud. Then once the arduino connects to the camera, you have to figure out how to get the snapshot to your desktop.

I am following the tutorial, https://learn.adafruit.com/ttl-serial-camera/using-comm-tool, to set up the TTL camera to take still images. I have bought and downloaded Parallels, and have arduino and commtool running in windows on there. Every time I get to the step about clicking on 'Get Version', I get the message 'Cmd time out'. I have tried adding 'Serial.begin(38400); Serial.println('starting');' as this person did to check the serial communication http://forums.adafruit.com/viewtopic.php?f=25&t=22936, but the serial is printing gibberish instead of 'starting'. Images below. Please note that I used blue wire for RX and green for TX. I have more images if needed, maximum of three means I can't put them all on this post. Breadboard seems to be wired as shown.


Hello,
I'm a french student, sorry for the mistakes...
I bought the TTL Serial JPEG Camera and an Arduino Yun 2 week ago. But this week I tried my camera but it doesn't work. Here are the hardware and the software these seal :
So, I haven't succeed to do this tutorial.I always got this message :'cmd time out'. I checked all the wire with a conductometer...And the port (COM3) was correctly open (green circle next to 'close') !
Then, I tried to take a Snapshot with this code (because the original code doesn't work due to the file 'SD.h' .This isn't the good method, with the Arduino Yun you must use the 'FileIO.h' librairie and use the Bridge) :

Code: Select all | TOGGLE FULL SIZE

// 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 <FileIO.h>
// comment out this line if using Arduino V23 or earlier
#include <SoftwareSerial.h>
// uncomment this line if using Arduino V23 or earlier
// #include <NewSoftSerial.h>
// 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 10
// 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.
// Using SoftwareSerial (Arduino 1.0+) or NewSoftSerial (Arduino 0023 & prior):
#if ARDUINO >= 100
// On Uno: camera TX connected to pin 2, camera RX to pin 3:
SoftwareSerial cameraconnection = SoftwareSerial(2, 3);
// On Mega: camera TX connected to pin 69 (A15), camera RX to pin 3:
//SoftwareSerial cameraconnection = SoftwareSerial(69, 3);
#else
NewSoftSerial cameraconnection = NewSoftSerial(2, 3);
#endif
Adafruit_VC0706 cam = Adafruit_VC0706(&cameraconnection);
// Using hardware serial on Mega: camera TX conn. to RX1,
// camera RX to TX1, no SoftwareSerial object is required:
//Adafruit_VC0706 cam = Adafruit_VC0706(&Serial1);
void setup() {
Bridge.begin();
// 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

Ttl Serial Camera Arduino Download

Before uploading this code I changed the wires to the 2 and 3 pins like in the exemple (but for the first test with the common tool, the wires were like in the pictures). And when I start the code, sometime I got :'No camera found?' sometime nothing.

Arduino Usb Ttl

Tkanks for your comments ;)

Note : The led of Rx flashes when I start the Comm Tool.
