As the topic name suggests I have started with a project to do my own custom instrumentation for my motorcycle.
The display unit itself is an HTC Touch Pro with Windows Mobile 6.1. Comms between the phone and the Panda II will be via Bluetooth.
So far I have already done the code for reading temperature, voltage and the Neutral state, all with the help of code I found on TinyCLR. The circuit example for the temp sensor I actually found on a Arduino related site and I researched voltage divider circuits on the net to bring the operating voltage down to safe levels for the analog pins to handle.
Now, my electronics skills are quite basic as well as my knowlegde of FEZ and the FEZ api’s.
The problem I am now facing is how to read the motorcycle’s engine RPM (speed should be closely based on the same principle). I have searched for FEZ related cases but couldn’t find anything helpful.
I would be picking up the RPM signal from where it goes into the existing tachometer.
- How would I go about connecting this safely to something like an interrupt pin on the Panda?
- Could I use code like William’s code as per the topic PulseIn() http://www.tinyclr.com/forum/6/714/ ?
Any and all help will be greatly appreciated.
