I 've a question about Timer() function. All knows that this useful function runs a branch every x milliseconds as specified when programming.
But what happens if the branch itself contains a delay() function with a value greater than the Timer() function ??
In other words, what happens in this example ??

Code: Select allTimer 1000, [test]
wait

[test]
delay 1500
Print "Hello World"
wait


I think that the Timer() function starts another cycle only when the branch is completely performed. Is it correct ??
Thank you

Normally I would expect entry to a timer or soft interrupt handler to either disable or allow options for dealing with further interrupts. Otherwise you might get a huge stack.. essentially though you need to write your code with awareness of what might happen allowing for how long stuff takes, which I guess is why you asked the question...
