I have a small LED matrix display that I use to show time and some messages contained in a circular buffer. The home button cycles through the different “applications” (CLEAR...

trigger is not reentrant. I mean that when I push the NEXT button and the buffer is empty, a second recursive call to trigger is made inside the STATE_MESSAGE_enter() function....

for example in this kind of state machine, the states are "chained". The machine moves from one state to another without external event. http://teachmetomake.com/wordpress/arduino-tutorial-state-machine

i'll try to make a post on https://hackaday.io About the state name or ID, I really don't know how to do without it. I understand It encourages some bad programming...

no news ?

I also miss the onState() function. But I think it's 2 different features. So far, for my current project, I don't need to call anything in the main loop and...

The thing is.... it's implemented.... But you have to use the "thelmos-master" branch. It works perfectly.... This new branch should become the master branch....
