![]() To get that kind of storage we’re going to use the same type that’s in every digital camera and mp3 player: flash cards! Often called SD or microSD cards, they can pack gigabytes into a space smaller than a coin. If you’re doing any sort of data logging, graphics or audio, you’ll need at least a megabyte of storage, and 64M is probably the minimum. There’s more flash (256K) but you can’t write to it as easily and you have to be careful if you want to store information in flash that you don’t For example, even the Arduino Mega chip (the Atmega2560) has a mere 4Kbytes of EEPROM storage. Most microcontrollers have extremely limited built-in storage. If you have a project with any audio, video, graphics, data logging, etc in it, you’ll find that having a removable storage option is essential. Using the SD library to read and write to a file on a SD card Introduction Arduino – 6 – DS3231 Real Time Clock Module.Arduino – 5 – Storing Data in Arduino EEPROM Memory.Arduino – 3 – Interfacing with Liquid Crystal Display.I'd appreciate that if you don't have input beyond non-helpful comments that you just restrain yourself from responding altogether there are plenty of other threads on this forum that you can give your input on. NOT before giving it a gentleman's effort. Grumpy_Mike, although I appreciate any input I can get here, I resorted to posting the question after exhausting resources and research time. For example: 手機遙控拍照 = Android + Jpeg Camera + Motoduino (Arduino) + Bluetooth - YouTube "I've been searching for an updated example." - There are examples that show it's possible, and it's certainly not cutting edge. Look at the compiler errors and see where you are going wrong. So that means you are not doing something right. I remove all of the 'SD' references and attempt to grab the saved binary data from the camera, but I only get compilation errors. Just do some sums and see how long a transfer will take, it might be much longer than you thought. I've been searching all around for an updated example that might point me in the right direction, but I've had no luck so far.Įither you are on the cutting edge of what an Arduino can do or it is impossible. (though I’m not sure which other ‘write’ function I could be referencing…)ĭoes anyone have an up-to-date example / code sample they can point me to or perhaps advice on how I can accomplish my goal of capturing the image using the JPEG camera and sending it to a remote device ? I’ve changed all of the NewSoftSerial library references to SoftwareSerial, and replaced the mySerial.print(, BYTE) with mySerial.write(), but I’m prompted with an ‘ambiguous’ reference to the write function error. I’ve also tried Linksprite’s example code for the TTL camera they provide (I have both) but it looks as though their code is also out of date. In the Snapshot example code, I remove all of the ‘SD’ references and attempt to grab the saved binary data from the camera, but I only get compilation errors. I’ve looked at the Adafruit tutorial for the JPEG TTL Camera module, but I’ve yet to be able to have the code compile properly. I’ve been searching all around for an updated example that might point me in the right direction, but I’ve had no luck so far. ![]() I’ve got the Arduino communicating with my computer through the bluetooth module perfectly right now able to send commands through the serial terminal and receive a response. Right now, I’m using a Duemilanove board with a ATMEGA328P and a BlueSMIRF gold bluetooth module. Since I’d like to get a handle on the whole process first, I’d just like to generalize it to saving the image to the computer. The END goal is to send the captured image over bluetooth to a mobile app to display. My goal’s to have the JPEG camera capture & save an image to a remote device įor sandbox purposes, I’d just like to save the image to my computer
