First steps: upload sample code
Compile the sample:
Convert the hex File to BIN

Press and hold the mode button and connect the cam to usb.
Now the Cam is in webcam mode

Upload the code to cam s-ram memory ( Wrong code can destroy your Cam !!!)
Yes. Now the Led will blink. We loaded our first code in your Cam.
Disconnect the cam from USB
Enable the uart
Solder a 10k resistor SMD chip.
Now the Gpio 4 ( Led ) is a UART Pin with 57600 baud rate ( 3.3 Volt ).
Restart the Cam, we get.
