oops, I just read this topic from the beggining. Sorry Greg_E, I didn't realise you found USB +5V, Battery and Power/Mode button connections already - edited my post. Also Xtreemtec mentioned about wireless modules - do you have any references to that informations? I'm just curious as found in firmware strings some references to Bluetooth, WLAN and even GPS (could be only an PrKERNELv4 OS options, but who knows).

Looking at the RF label it looks like that is the place they planned to solder the RF module down, so I would think there is no on board RF at this time. I didn't see anything that looked like a ceramic antenna in the pictures and I haven't pulled my camera that far apart to check for myself.

Well for bluetooth you don't need a lot of antenna. A simple trace on the board say 3 centimeters is enough.. Well i have been thinking that the white space on the board with the gold plated tabs could be the place were it should be. Otherwise it could be just the programming port to enter the unit with crashed firmware / no firmware. Sort of Jtag or ISP port..

Found on: http://www.actioncameras.co.uk/microsit ... ProHD.html

Every HD Helmet HERO is outfitted with an internal transceiver that allows you to add a wireless stereo mic for top quality sound recording in any environment. The wireless mic takes your sound recording to a next level.

Add an optional remote with a omni-directional range of 30’/10m and a preview screen and you’ve got one of the most advanced HD camera systems on the planet.


But maybe this is not a very relliable source.. As it is not stated by GoPro. I still keep my head on something like bluetooth.. It strokes with the range of 10 meters.. Also in a other project i helped designing it was easily integrated to use bluetooth as communication between multiple devices.

We will see...

Hi all,

over at http://chdk.setepontos.com
pixeldoc2000 managed to get the Serial Console to work:

Check it out!

Wow, Bingo!
It's funny, I worked at that connector today also Realy good job pixeldoc2000 and Janmartin!!

I can confirm pin 10 is VCC=3,3VDC and pin 6=GND, also measured impedance of other pins and found as below:


Looking at Ambarella Jtag port, seems to be similar (except RST pin - camera has got 10k pull down resistor, drawing shows pull up):


Below other side of PCB near the connector:

Note the resistors R44-R49. They seems to be corresponding with connection pins.

By the way - good idea to join the forces of both communities on that thread!

Hi all,

I just wrote a new article about what I am doing with 5 GoPro HD cameras:

Guys, please find I2C sequence during picture shot in attachments. Unfortunatelly, when tried to repeat the same sequence by external I2C master connected to the bus, camera doesn't took a picture - maybe there is something missing or first, external master must talk to AMBARELLA somehow. I scanned the bus against all I2C addresses and except broadcast address (0x00[hex]) there was only 2 more (0x30[hex] and 0xBA[hex] as expected).

Jan, looks like pixeldoc2000 has good background with those OSes and ARM architecture. Hopefully some I2C procedures can be discovered by debugging the firmware.

Hi guys.

Sounds very promissing. Anybody have enough experience to create some code and try?

Wow, guys, I am so glad that someone dug into the boards and found a LOT more info than I was able to find. I am excited about the future of controlling this camera. I've curtailed my hobby spending lately, but after I'm back from vacation, I'll be looking at what I can do to upgrade my FPV RC truck outfit.

(I'm not excited by the apparent/possible I2C requirement for triggering it, but that's what microcontroller boards like an Arduino mini are for.)

Ok, I'm rigging up a GoPro in a race car and due to my seating position, race harness, etc I can'r reach the GoPro when seated in the car. i also don't want to have to worry about turning the GoPro on/off before getting in the car...what I need is a remote control!

So...

I'm going to buy iPod connector to access the following pins on the GoPro Bus

Pin 12 Pwr/Mode
Pin 23 Adaptor (Battery Out)
Pin 30 GND

I'm going to wire pins 12 and 30 to a momentary push button (puch to close contact)

I'm going to wire pins 23 and 30 to a LED via a 150 ohm resistor.

With the GoPro set in 'single button' mode, the plan is when i press the button the GoPro will turn on and start recording automatically and the LED will light to tell me recording is in progress (remember I can't see the GoPro from where I am sat).

Does this sounds a sensible plan?? Have I missed anything here?

I'm also planning to try using pins 14 and 15 to feed audio into the Gro Pro from an active external microphone, so I can get decent sound quality. has anyone here tried feeding audio into the GoPro and recording it?? Any tips/advice? Do you have to be in a certain mode for this to work?

Cheers!!
