Re: JST conector type

Hi Alex, 1. You should have two cables with JST connector soldered in the plastic bag with your StereoPi as a spare part. We put them in each board's bag (regardless of the other kit content). 2. Exact connector type name is "JST EHR-2". Some links: Digikey Octopoart 3. As a workaround you can use t...

Re: trigger multiple pi's to take image

You can consider StereoPi as the Raspberry Pi with 2 cameras. I.e. you can use all software designed for the classic Raspberry Pi, plus use the second camera option. So your way (test the code on the Pi and then run it on StereoPi) is correct!

Re: Oculus Quest 1/2 application

Hi Neilpstevenson,
For the app version available for download we used the latest Oculus SDK, where GO support is already turned off. But we’ll try to compile this app with the older Unity and OVR package to run it on Go. Our early version was tested on all mobile Oculus (Go, Quest 1 and Quest 2).

Re: Raspberry reboot yourself

Hey Dragon, In 99% of cases of a reboot under high load, the reason is the lack of power of the power source (not enough current provided). We recommend using at least 2A PSU (and Raspberry says at least 2.4A). It is better to get a well-known (branded) power supply, as with the no-name and declared...

Re: Livestreaming to a web

Hi AlexVega, Congratulations! :-) As for raspivid and "-fs" key. As we mentioned, we compiled a special version of raspivid from source to add one feature, which is not available in stock raspivid. Original (stock) raspivid can't display stereoscopic preview on HDMI screen. So we added "-fs" option,...

Re: Recommended CM4 for Stereo Pi v2?

Using 4Gb for ramdisk is a good approach. In all our experiments recording of encoded video and images is not a bottleneck, but if you are planning to record RAW video or photo - this might be critical. As for 8Gb CM4 - as I know, these modules are produced by Raspberry Pi for B2B customers only, an...

Re: Oculus Quest 1/2 application

We are having exactly the same latency as with our old Android application. It depends on settings and your WiFI network, and usually is near 100 ms (vary from 80 to 120 ms).

Hi Zoldaten,
If your CM3 is equipped with the eMMC, you can't use the micro SD. So please upload it to eMMC.

Re: Recommended CM4 for Stereo Pi v2?

Hi Dubrawski, CM4 has the only USB port exposed, and this is USB 2.0 port. We added the USB HUB chip to split this port into 3 USB ports (two of them are USB A, and the 3rd one is on the pins for advanced users). You can take a look at the "No bottlenecks!!! SPEEEEEEEEEEED!!!!!!!!" section in our ar...

Re: Recommended CM4 for Stereo Pi v2?

Hi Dubrawski, Our choice is CM4 Lite (now eMMC) + Wireless (BT and WiFi) and 2Gb RAM, or "CM4102000" according to RPF. RAM: Actually, for SLP even 1 Gb is enough. We choose 2Gb as it is better for the OpenCV (compilation from source). WIRELESS: Good thing and the wireless module is just $5 more expe...

Hi jedwards123321, Go/Quest family is android-based, so we created a special application for them. AFAIK, Rift is connected to the PC. I had no chance to play with it, but, if it supports a kind of PC screen mirroring, you can use our Windows application for the video receiving. Yep, we never announ...

Re: Directly drive 3d TV in FullHD?

Hi Andreas, We try to play with 3D TV, but no success. We used all possible settings, but TV does not recognize Pi's HDMI output as a 3D. The only way was to "force" 3D SBS mode in the TV menu - and this approach works fine. One trick for you: if you turn on "decimate" mode (it is '-dec' command for...
