Re: OTG support

I saw the small image extraction on the wiki, but at the time, I did not catch it. Sorry, could you please clarify this notice? :-) Retrospectively, I think I was tired, because I did not even read the bottom text which I usually do. I was confused to not know where the top right wires go, but actu...

Re: Using USB Cameras

Realizator answered while I was still typing. Here is my answer, as a few elements are complementary. The main advantage (in my point of view) to use stereopi is because of the access to the two CSI buses of the raspberry-pi module, which allows for fast fetching of the two signals and as a conseque...

Re: Basic stereophoto with raspistill

Nice.
I saw that the -3dswap option does not work, but it was not a big deal for me as I prefer the 'parallel' side-by-side format.
The use of "-cs 1" is a clever trick I would not have thought of.

Re: OTG support

Thanks very much for the schematics! I saw the small image extraction on the wiki, but at the time, I did not catch it. With the whole schematics, it is easier to understand. The schematics also allowed me to understand that the USB-slave jumper is not related to OTG (and totally useless in my case ...

Re: apt-get update/upgrade

If you read[1] your error message, you can easily understand what happens: Could not open file [...] - open (30: Read-only file system) As I noticed when I received my stereopi, the root file system is read-only (which totally makes sense for embedded systems) thus you have to remount it read-write ...

Basic stereophoto with raspistill

Here is how to shoot a basic stereophoto from the command line. Because it was not so obvious, I share the way I just found. Note that no other programs should control the video bus, thus you might need to stop the autostarting stereopi software suite [for example by stopping everything started in r...

Re: 3d cam with mobile phone as viewfinder and controller

Hmmm... Before formatting, system checks if it is any FAT32 partition, and should not format or delete anything if partition exists. Our setups has a hundreds of reboots and all recordings are safe. May be your fixed partition size or other changed settings affects on this behavior. I confirm the b...

[Solved] OTG support

I post in hardware section because, as a BSP issue, it is more related to hardware than user software. Context: Ethernet access is not always convenient, but yet networking is useful. Hence, I often use USB-net to connect to my boards. Firsts tries on stereopi are failures. Question: As schematics s...
