ARTX: DIFFERENCE ISR AND OS FUNCTIONS
Information in this article applies to:
- ARTX-ARM All Versions
- ARTX-166 All Versions
QUESTION
Why are there different naming conventions in the ARTX Kernel Function reference. What is the real difference between the functions isr_evt_set and os_evt_set?
ANSWER
The prefix indicates the usage of the functions:
- Functions that begin with os_ may be called from a task but not from an interrupt service routine.
- Functions that begin with isr_ may be called from an interrupt service routine but not from a task.
The difference is the way the task status is synchronized internally with the kernel.
