:::ok so apple must have merged the node's because [[/dev/compass_0|compass_0]] is the [[Magnetometer]] and it does not exist on my iPhone 4 instead it uses [[/dev/compass2_0|compass2_0]] witch is the [[Gyroscope]] ( [http://yfrog.com/757o7p] ) --[[User:Liamchat|liamchat]] 19:00, 28 October 2010 (UTC) |

| − | :::: Just because a node doesn't show up, it doesn't mean the hardware is physically not-present. The iPhone 4 has an Accelerometer, Compass, and Gyroscope. WWDC sessions confirmed this on the first day. Also, the gyroscope does not give you any gravity/acceleration data, which must be obtained exclusively from the accelerometer [this kind of data thousands of apps depend on]. The gyroscope deals with rotation about the 3 axises only. The compass app obviously uses a magnetometer because of its frequent interference warnings. |

Data Sheet
User LiNK removed a link to a data sheet. The info there was quite useful. Why did you remove it? Was it the wrong chip? -- http 18:10, 28 October 2010 (UTC)
- here is the photo of the motherboard [1] the STmicroelectronics lis331DL is the chip on the 3g and ipod 2g and has 3-axis digital --liamchat 18:35, 28 October 2010 (UTC)
Newer devices still use accelerometer (plus new gyroscope)
I also remember this being said at Steve Jobs' presentation (or somewhere else). So if you want to change this again, please discuss here first. -- http 18:27, 28 October 2010 (UTC)
- i thought apple had removed the Accelerometer ( as they did with the Magnetometer ) but i have not found the node yet --liamchat 18:41, 28 October 2010 (UTC)
- Not to drift off-topic, but the magnetometer/compass is still present in the iPhone 4... --Dialexio 18:46, 28 October 2010 (UTC)
- ok so apple must have merged the node's because compass_0 is the Magnetometer and it does not exist on my iPhone 4 instead it uses compass2_0 witch is the Gyroscope ( [2] ) --liamchat 19:00, 28 October 2010 (UTC)
