HI Timo:
I am working on enabling our accelerometer in Nokia's sensor framework.
Here are some issues i met:
1. hard coding of adaptor name. accelerometer chain and accelerometer hard
codes the adaptor name to
"accelerometer". If all adaptors have same name, sensord failed to distinguish
right one to load.
2. non-industry data format. For accelerometer, the generic data format is
[-Xg, Xg] in float, while Nokia SF
uses integer for each axis value. If the framework will persist in integer,
there should be a document describes
how should another driver map its data. Otherwise accelerometer adopters can't
feed their data into systems (e.g filter system)
3. context sensor requires too many sensors. Context sensor requires
accelerometer, compass, orientation sensor, which
means at least needs accelerometer adaptor and magnetic adaptor. For me only
have an accelerometer, how can I play
with context sensor to provide screen rotation property?
4. while Nokia SF require root to run, there should be a init.d service file to
make it start during system boot. I didn't find it in source.
Hope your feedback. Thank you.
