I have the board and I have done some interfaces with it so far. Now I'm trying timers and interrupts, and I don't have an oscilloscope to examine square waves.
Is there any simulation software for it? or shall I use any cheap chip I have to develop some input capture software to work as an oscilloscope and interface it with TM4C123 ?
