If you're already got wheel ticks and a time base, you can trivially compute accelleration. You can only do it for lengths of one wheel circumference at a time, but that's a plenty good enough granularity for measuring a bicycle ride. This will also be a more accurate than a MEMS accellerometer. ******************************************************************** Embed Inc, Littleton Massachusetts, http://www.embedinc.com/products (978) 742-9014.
