The [[Nokia N950|N950]] is the second [[Maemo]] / [[Harmattan]] device which can be used as a phone. It is a development platform for the [[Nokia N9]].

This is a quick outline of a page, as I'm filling it in.
 +
The [[Nokia N950|N950]] is the second [[Maemo]] device which can be used as a phone. It is meant for development for [[Nokia N9|target platform N9]] under maemo-6 harmattan recently renamed to meego-harmattan, though the core OS still is maemo based and unrelated to http://www.meego.com aka meego-meego aka meego_proper, nevertheless several APIs and the UX try to approach the meego_proper appearance.

Nokia seems to refer to this device as N9-devkit: https://www.developer.nokia.com/Devices/MeeGo/#article2  http://www.engadget.com/photos/nokia-n950-press-shots/#4243171
It is only available to developers, and not as a consumer product.
It is only available to developers, and not as a consumer product.
It shares much hardware with the [[Nokia N9|N9]], with the notable differences that the display is TFT, not OLED, and there is a hardware keyboard.

Due to the use of different display technologies, on the N9, developers should avoid one pixel width fonts(?) and graphical objects with lines one pixel wide. Also avoid the extensive use of bright colors, especially white, when developing for OLED displays as this increases the power consumption (typical for OLED displays). See [http://en.wikipedia.org/wiki/PenTile_Matrix_Family this page on common OLED pixel arrangements for more info]

===Accelerometer: LIS3LV02DL===
+
===Accelerometer===
-
 
+
-
Sysfs attributes under /sys/devices/platform/lis3lv02d/:
+
-
 
+
-
* position - 3D position that the accelerometer reports. Format: "(x,y,z)"
+
-
* rate - read reports the sampling rate of the accelerometer device in HZ.
+
-
* write changes sampling rate of the accelerometer device.
+
-
Only values which are supported by HW are accepted.
+
-
 
+
-
* selftest - performs selftest for the chip as specified by chip manufacturer.
+
-
 
+
-
By default output values are scaled between -32768 .. 32767
+
-
 
+
-
===="freefall" device====
+
-
 
+
-
It supports blocking operations, poll/select and fasync operation modes.
+
-
 
+
-
You must read 1 bytes from the device. The result is number of free-fall
+
-
interrupts since the last successful read (or 255 if number of interrupts would not fit).
