Interrupts in FlashForth5

[Radolf von Salis]

Hi Mikael,
In my guide to FlashForth5 I have an example for interrupts. See page 28 of the guide FlashForth5.pfd in the attachement!
When I call the first time irq_init all seems to be ok. The second time I get something like
irq_init
1 ok<#,ram>

2
3
4
5
6 Interrupt abgestellt

Something does not work properly. It may be that I must insert ei and di in the appropriate places, or that I can not leave the int_routine at this way. Can you give me a hint? Thank you!

You should not print anything from inside an interrupt routine. It will not work reliably.
Printing should be done from the operator task or from a background task if the backround task has a output device.

Thank you Mikael. It seems that with an interrupt routine also no data can be exchanged via data stack, but only via a variable.
