Re: which rom400_task routines are safe to call from an isr

Waking up tasks from an interrupt doesn't work too well.  Instead, you can
register a polling routine using the User IO Poll routine library.  It is
safe for the polling routines to call the task functions, so you can have
your polling routine monitor for a wakeup signal.

Subject: [TINI]which rom400_task routines are safe to call from an isr




I have some C code and  want to wake (or spawn) a task
from an ISR.  Because of the way interrupts work on
8051 processors I assume there are limits on what i
can do with the rom400_task task scheduler rotuines
from an ISR.

- which rom400_task routines are safe to call from an
isr?

- are there any recommendations on how this should be
done on the 80c400?
