constant 1hz output with state machine

I want my uC to output a 1hz signal to an LED to show that it is stepping through the code (for debugging), but I'm not sure how to do it properly when my program is a Moore state machine.

It would work if I put the 1hz code in every state but it is messy. What's a good to do this?

Thanks!

It would be easier to drop a putc() statement in each state.
You could set the hardware UART's baudrate to 115200 bps
and it would only take 86 us to send a character. As long as
your states took at least that amount of time, you wouldn't see
any delay added to them.

In other words, this is the quick "no brainer" way to do what
you want (ie., to track state progress).
