A couple of newbie questions

What is the best way to communicate between tasks for the following:

Multiple tasks can send a flag to to TaskX and when done in TaskX, TaskX will reset the flag. I have normally done this with a global variable, and any task can set this var to NOT Zero and when TaskX is done, Task_X will set the var to zero. Reading the manual does seem a bit confusing as the are multiple options for this

I can't seem to locate any definition guide, what does the various prefixes mean, ie xSomething, vSomething etc

I'm using this on an Arduino for now and all tasks have the same priority, so essentially a round robin scheduler.

Thanks K

Have a look at event groups. They allow you to set and clear bits in thread safe way:
