camera library

Recommended Posts

I bought a JPEG Color Camera Serial UART Interface (TTL level).
I connected it with Arduino Uno. I tried the code which you have provided but it did't work (there is an error in the library).I used Arduino 1.5.6 and "newsoftserial" library.
I will be glad If you can provide me with a code that show the image in serial monitoring.
Thank you

// 1. SD must be formated to FAT16
// 2. As the buffer of softserial has 64 bytes, so the code read 32 bytes each time
// 3. Please add the libaray to the lib path

// * SD card attached to SPI bus as follows:
//** MOSI - pin 11
// ** MISO - pin 12
// ** CLK - pin 13
// ** CS - pin 4
