Trying to give a little back, A timer module
· My project is going in to an airplane. When you rent an airplane, you pay by the hour. The airplane has a meter in it that keeps track of how long the plane is turned on. Every time you rent a plane you log in the times to keep track of how long you ran the engine. You also use this time for maintainance.
· The company that makes the standard meter is or was·the Hobbs company so they became known as the "Hobbs Meter".
· This is a module that updates a value called hobbsvalue. It updates every second. It also flashes an led on pin 27.
·· Put this in startup area. Make sure to put a "long hobbsvalue" is var section
· Put this anywhere that is convient.
Timerb is attached and commented on how to modify the freq. The timerb function uses the fact that when a counter rolls over the pin will blip high. Counter b sees this blip and updates a counter. Because the counter does not roll over quickly, this module probably only works for seconds and up.
Props out to Mike Green and a few others for the help in putting this together.
Hope someone can use this.

When I had a boat (before I was married) I had an hour meter on that engine that must have been similar to the one you described in that airplane. I believe it did say "Hobbs" on the face of the meter too.
