Nice accelerometer for basic stamps...

Posts: 46,084
I've seen some mention here and there of accelerometers in the group,
but no mention of the LIS3L02DS. It seems to be a new chip, but it
looks wonderful. I2C or SPI protocol, 3 dimensions of measurement (+
and - on the XYZ axis), wide temperature range, measurement scale of
either 2g or 6g (which is more 'everyday' values), shock resistant,
and an interrupt!
After looking at the other solutions I've seen for accelerometers,
this looks pretty good. Its digital (so I don't need to keep
monitoring it for some period of time to pick off an analog voltage)
and it'll signal when acceleration is above or below a certain G
factor in a certain axis.
No idea on costs. I can't find anyone carrying it yet. The part I
really hate is the SO24 package. Great. Another surface mount that I
freaking can't solder and use on my own. Over half the pins they don't
even use! LOL.Maybe that'll make soldering easier. [noparse][[/noparse]1-5 and 16-24 are NC.]
Disclaimer: I have no direct or indirect relation or interest to this
chip, manufacturer, or other party of significant interest. This just
look like a neat solution to discuss to the accelerometer question.
I think I can make some use of it myself in my steroid version of
those handheld gizmos that writes messages in the air. By using the
accelerometer, I can tell if it is display left to right, or right to
left (or that someone is trying something totally different). That,
and mine is no longer handheld. It is mounted on a scrap picket fence
plank I got from Home Depot. More like a fat wand.

but we don't know how far down the road that is.
Maybe this year or next year or never.
An announcement like this is to test the waters so to speak to see if
anyone is interested in buying tens of thousands of units from ST
electronitcs.
If they get interest they'll finish developing it. Or they might delay
or drop the whole thing still. They could get entangled in some kind of
a patent violation with one of the other companies that make these types
of MEMs based chips.
You can easily simulate this now by using one of the accelerometers we
already can get and hook up a Basic Stamp to the output to provide the
I2C serial type of feature for the accelerometer. Then another Stamp can
query for the information whenever it wants to. You could even do this
using TTL serial too, which might be even easier than I2C.

3-axis acceleration. If not, the 2-axis ADXL202 family from Analog
Devices has easily implemented PWM outputs, and code samples for BS1 and
BS2s already exist. As to SO24s, soldering them once to an adapter
(such as Surf Board) has some advantages.
