I received the camera on Tuesday of this week, and tested it that night. I had the CommTool working, and I was taking pictures.
Then, I hooked it up to the arduino, and took a few sample pictures that saved correctly to the SD card.
All of a sudden, on my probably 10th test, the camera stops responding.
I've tested the response on power up and I get:
Ctrl infr exist
which indicates that the TX pin is working fine and I have the right baud rate selected.
However, whenever I try to Get Version or System Reset with the CommTool, I always get a timeout command.
This, to me, indicates that the RX pin is somehow broken.
My setup is exactly the same as the tutorial, with the RX pin divided down by the two resistors that came with the camera.
Also, unfortunately I need this camera working by Friday night, so any help is appreciated, and quickly if possible.
