ACC和GYRO需要散热?
MEMS SENSOR的功耗有多少?CALIBRATE又怎么了?
加一个这种SENSOR需要你的FIRMWARE做很大改动?

你算算给nexus one加个这个,
总共需要多少时间吧.从设计到出货需要多少时间吧.
是不是trivial.

ACC和GYRO需要散热?
这不是废话么.你改了设计,不测散热?

谁给讲讲有 application 怎么利用 Gyroscope 的功能, will there be new set of
library in SDK specific for Gyro or what?

加一个GYRO的DRIVER就行了。看是什么接口的。
你说的那些SDK是应用层软件的东西。跟底层硬件没有直接关系。

iphoen OS reference library应该会有更新.
查UIDevice.xxx就行了吧,也许会有demo codes

你牛B,给解释下为啥netbook仿造一个需要花14个月.
那不是更trivial.
gyro sensor要用好,调试说不定就的学两礼拜.

他估计来年lay板子走线,DVT,PVT,产线制程,认证这些根本不了解,没法探讨。

别散热散热挂嘴上。你讲话要有根据。找份datasheet看看好了。3D accelermeter与
gyro有散热问题绝对是想当然。

你知道iphone用的是多大功率的芯片?
外围加不加部件? 外围要加多少部件?
你的根据在哪?
你拿拖拉机跟 iphone的设计作类比.很好很强大.

我老早就说过,和民工讨论设计就是浪费时间,实际上加类似gyro acc麻烦大了,产品
的设计都可能要改变,甚至影响外观
工业设计,没到pcb就一堆头疼的问题,后面的撞击测试设计都可能要变,呵呵。几个
工地上搬砖的民工也敢开牙,呵呵。
IT这个行业名声是彻底坏了,连包工头都自称product manager了。

iphone一年最少出几百万部.(itouch今年好像就是8M以上.)
据我所知这种复杂点的sensor,都是吹得牛B的一塌糊涂.
其实内部都是一屁股擦布干净的修修补补.
这玩艺儿敢往上加.还加了那么多别的feature.
说实话我给乔总捏了一把汗.我这儿是相信他的执行力.
但说不定回头出bug也未可知.

今天在这里讨论的digua,biggu,wavelet02,还有我都没有说ixx平台伟光正。PS Vita加了gyro和accelerometer也是大家看到的进步。

那我用同样的理由也可以说 iPhone 正向 Wii 手柄/主机
一体化迈进,accelerometer/gyro 这些必要的传感器都有了,
需要解决的是外接显示的问题。
但是要防止任天堂背后捅刀子告果子侵权,LOL.

With summer approaching, we are again suffering another Microsoft

我是实用主义者,甚至觉得什么accelerometer,gyro什么的对我都没吸引力,有个键
让我转向屏幕我都不会在意:),主要下面说的简单几件事,运行速度在能忍受的范围,
便宜点,就成了,但最好是个大厂子的,有点保证。

I'm newbie in sensor and IMU so my question is probably very basic for
others, but it's already puzzled me for days.
I'm using Mahony's algorithm to calculate Euler angle of my device; the
three angles looks correct when put the device static or move/rotate the
device slowly; however, the Yaw angle will become unstable and incorrect if
rotating the device fast. Could someone help me solve this issue ? My device
