gopro

Thu Jul 24, 2014 7:50 am

hi
i am trying to work out how i can connect a gopro (hero 3) to the raspberry pi through the gpio port on the raspberry pi and the bus on the back of the gopro.

how can i do this in a way that would be able to save the video onto a usb in a format such as mp4 or avi?

i think the most likely ones that i will need are pins 2, 20, 21

but how do i get the pi to understand it?


the following is the layout of the pins for the gopro, i
GND
R video out - component Pb/Cb or composite
G video out - component Y
B video out - component Pr/Cr
USB +5V USB power
USB +5V USB power
USB DP-B USB data line D+
USB DM-B USB data line D-
GND
HPR audio out right channel
HPL audio out left channel
PWR/MODE power/mode button
V3.6
IN1R audio in right channel
IN1L audio in left channel
IR IN input IR receiver
TRIG (?)
GND
ID1 digital input
ID2 digital input
ID3 digital input
ID4 digital input
ADAPTER output (Seems that it could be used as status...)
ADAPTER output (?)
WBAT+ input - ext. power for camera?
WBAT+ input - ext. power for camera?
GND
DATA interface I2C
CLK interface I2C
GND

(preferably hd video)

would there be a way to plug the gopro into the camera port and trick the pi into thinking the gopro is a pi-cam?

Best (only?) hope is to connect the USB points of the GoPro interface to a USB socket on the RPi. If you are lucky the GoPro will then appear as a USB drive to the RPi.

I don't have a GoPro. Does it not have a USB port for connecting to USB equipped computers?

Edit: A look at page 54 of http://cbcdn1.gp-static.com/uploads/pro ... VD_WEB.pdf
reveals that it does have a USB port and the the camera will appear as removable storage.

Not really possible over the USB connector which is all you would be able to use. GPIO's are not fast enough for video.
