Will Arduino clock speed sufficient for Nissan Camshaft Angle Sensor decoding.

Hi guys,

I'm really excited on the possibility of using Arduino Uno to do a simple decoding of Nissan Camshaft Angle Sensor(CAS) for Nissan Skyline RB25DET engine. This is my first posting in this forum so please bare with my "noobie-ness". The CAS gives out two squarewave signal. The first signal outputs 6 pulse and the second signal outputs 360 pulse per engine revolution. Lets say maximum engine revolution is 10k rpm so the second signal could run at 3.6MHz. My objectives are to:

  1. Count 6 pulse per rpm signal and output one signal per rpm.
  2. Count 360 pulse per rpm signal and output 24 signal per rpm(equally 'spaced').

Basically i wanted to achieve this hardware modification through arduino but not quite sure if arduino could handle the high resolution of the input:

800×600 105 KB

Lets say maximum engine revolution is 10k rpm so the second signal could run at 3.6MHz

How so?
10k RPM is 166.6Hz, so 360 times this is 60kHz

Oh, i totally forgotten about minute-second conversion. So i guess I'll go ahead with the project. Thanks for the prompt respond :slight_smile:
