Well the code provided by Joe works great now. I really appreciate Joe posting this and then taking the time to help me get it working. I have three machines that I really need tach's on, a spincaster, a cnc mill, and a lathe and this display and Joe's code fits the application perfectly.

The display I got from Sure Electronics was this one. It was only $14.00 delivered and is quite bright.

I'm in the process of setting up a hall effect sensor as the pickup and it should work fine for this.

Thanks again Joe,

Sam
