This page summarizes device-specific settings and supported peripheral hardware for Raspberry Pi 3 Model B.
|Choose a free sdcard you would like to install emteria.OS onto. Attention: Please use a card of at least speed class 10 or higher (UHS), since the read/write speed of the sdcard will heavily influence the system speed. Some cards are known to not work correctly with the Raspberry Pi; this is a hardware issue we don’t control. Please check this comprehensive list for your specific SD card.|
|Use the emteria GUI installer for your operating system in order to flash your sdcard. Warning: all data on this sdcard will be lost!|
|When the installer finishes, take your micro SD-card out of your computer, insert it into your device and power it on. You should see a short text boot sequence followed by the emteria logo animation.|
All standard HDMI screens should be supported. Please see the section below for more information about the supported resolutions. The majority of USB-based touch controllers should also work out-of-the box. Following screens have been successfully tested by us with emteria.OS 0.5.x:
|52Pi 5" touchscreen: The 800x480 capacitive HDMI touchscreen with USB controller for multi-touch.|
|Raspberry Pi 7" touchscreen: The official Raspberry Pi 7″ touch screen display with 10 finger capacitive touch.|
|Waveshare 7" touchscreen: A capacitive HDMI screen with an USB touch controller.|
|Waveshare 10.1" touchscreen: A capacitive HDMI screen with an USB touch controller.|
The audio jack is used as the default audio out. If it doesn’t work in your setup, or if you wish to change the default behavior, please refer to HDMI_FORCE_EDID_AUDIO and HDMI_IGNORE_EDID_AUDIO options as specified by the official documentation. The emteria.OS also has built-in support for USB speaker and USB microphone without additional configuration.
Built-in support for the Official CSI Camera Module without additional configuration.
Accessing GPIO is possible just the same way you would do it in Linux (via sysfs). We are also planning on adding proper Java API for that, but it will take a while.
Built-in support for ODROID’s USB GPS Module without additional configuration.
Built-in support for NXP’s USB NFC Dongle without additional configuration.
The emteria.OS is running with many different screens. In the vast majority of cases, it correctly detects the resolution from the connected screen without any changes required (e.g. using the provided EDID information).
A custom resolution can be enforced by using use
vc4-fkms-v3d overlay (instead of
vc4-kms-v3d). For doing so, simply mount your sdcard and edit
Some screen/graphics format combinations do not work with
vc4-fkms-v3d. In such cases you can change the used resolution manually, by editing two files (you need to mount both
system partitions first):
|/boot/config.txt||Old value||New value|
|hdmi_cvt=1280 720 60 6 0 0 0||hdmi_cvt=1024 600 60 6 0 0 0|
|/system/build.prop||Old value||New value|
Additional applications can be installed in same way as on standard Android devices (ADB, Download, F-Droid), except that “ADB over Ethernet” should be used instead of “USB ADB”. Example for using F-Droid can be found here.
