Mr. Benedikt asked:
btw.
when is the dmx tut finished?
does the dmx code work tight?
what means "Therefore the program will stop the interrupts when sending data"?
We are working on it, we just released a first prototype because the Italian guys are needing some DMX for a project.
The program we show there works, Tomek Ness is preparing an example controlling a lamp and some colour filters from an arduino with an LCD and two buttons It is a matter of a week more or less.
We have to unable interrupts from the microprocessor. Interrupts are a resource in a microprocessor that will stop the program to perform a certain task. E.g. a timer is using interrupts to announce the timeout, so when running a timer if we are sending DMX lines, we will not be able of being accurate counting times.
