accelerometer input

Archiver

HI all,
I've been looking for an answer to a few technical questions regarding the
basic stamp 2p. I 've been playing around with it for a while, and i'd like
to interface an array of Analog Devices accelerometers to it.(yes, i realize
parallax offers their own..but this one is 1/3 the price and 1/3 the size).
To build the simple interface circuit however, i need to know the
"microcontroller counter rate" (the output of this sensor is duty cycle
modulated). Is this simply the clock frequency of the BS2p?

thanks,
Christian

You can use PULSIN to measure the high-time of the signal, then a separate
PULSIN to measure the low-time of the signal. From there it's just math.
