  1. Hi all, brand new to the forum and just received my analog 2 discovery. Pretty impressed with it so far. Actually I'm working on an interrupt driven spi interface to a SPI accelerometer. All is working well, but I would like to configure a button...say in the Static I/O tool, or the patterns tool whereby it can represent my interrupt in. I want to be able to trigger a single interrupt, this will trigger my Interrupt Service Routine, my scope and logic analyzer and I will be able to observe the Single SPI transaction. So, restating the question : "I just want to configure a pushbutton using a Analog discovery 2 instrument that will act like a button driving a one shot (Monostable Multivibrator in the ancient vernacular) with a pulse length of about 20us. I push the button say in the Static logic tool and 20 us later it returns to zero. Any quick ideas here...I could probably read a while and figure out a strategy but I'm looking for a quick fix.. Thanks. Glen
