Create a timing source from RT FIFO reference

Status: New

I'd like to create a timing source from an RT FIFO reference to drive a timed loop. The timing source would tic whenever there an element is placed into the RT FIFO, facilitating a timed loop to be configured for reading elements from the RT FIFO as they become available. This would only be available for blocking mode on read. Once the loop awakes, the user can then read the FIFO with a 0 timeout to get the data.

 

This would provide all the nice features of timed loops to loops that need to be timed by data showing up in the FIFO. Right now you have to place a while loop that blocks on the RT FIFO and wrap it in a timed sequence for CPU assignment and priority.

 

Also, combined with the idea posted for multiple timing source for a single timed loop, could be very powerful.
