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]].
+
-
 
+
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.

==N9/950 differences==
 +
{{fixme:Make into nice table of differences}}
 +
* N950 is physically larger and is made out of aluminum, whereas N9 has a polycarbonate unibody.
 +
* N950 has a physical slide-out QWERTY keyboard. The N9 is a touchscreen -only device.
 +
* N950 has a 4" TFT LCD display whereas N9 has 3.9" AMOLED display. Display resolution is same on both devices (854x480). Due to the use of different display technologies, developers should avoid one pixel with 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).
 +
* N950 has a different physical camera module than N9. Both camera modules have very similar image quality (Carl Zeiss branding in N9) and both modules support 8Mpix image mode.
 +
* In the N950 the front facing camera is in top right corner and on N9 it is in the bottom right corner. The actual camera module is same.
 +
* N950 supports Bluetooth version 2.1+EDR, whereas N9 supports version 4.0
 +
* N950 does not have support for NFC
 +
* N9 has slightly more sensitive magnetometer and ALS
 +
* N950 has 1320mAh battery, the N9 has 1450mAh battery

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===
+
-
 
+
-
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).

The OS is maemo-6, codenamed Meego-[[Harmattan]]. The core OS still is maemo based and unrelated to http://www.meego.com/ though APIs and the UX are in some cases similar to meego_proper.
