I am working on a project where I am reading High/Low changes from an XBand Motion sensor from Parallax (32213). While the software solution works fine it is a resource problem as I have other sensors to read from the Micro Processor in it's scanning loop. Someone recommended looking at using an LM2917 FtoV converter so I can simply read the voltage on an analog input to the MP (I think the max is 3.3v).
Does anyone have experience with the LM2917 that can suggest a circuit to use for this? I can handle the software end, my hardware skills are a bit rusty.
