While working on the software for the light box timer and thinking about polling variables to check if the desired time has been met, I thought that it would be easier to just poll a single variable.
So a flag bit are set in say B0 (bits 0 and 1) and the statement just looks for a single number in that variable - this led me to think about interrupts.
I have had a look through the commands list and there is no reference to internal interrupts from software. only inputs from the outside world.
Is this a limitation of the firmware? something that simply wasn't thought of? or considered and not used due to only being able to run one interrupt at a time?
