Thanks, but I got the idea from someone on this forum.

One thing I have not been able to figure out. The main loop looks for new input from the OI, and if it doesnt see it, it call the user_fast code.

That took me a little time to figure out. The fast code (Process_Data_From_Local_IO()) is called every loop of the while(1) loop. The "slow" user code is called in addition very occasionally in the while(1) loop when new data is ready (if (statusflag.NEW_SPI_DATA) ).

Don't see anything in the fast code to throttle it back - can you put your toggles at the beginning and end of the fast section and see how fast it runs with your scope for us?

I did that, too, at the time, just to see. I didn't measure the rate, but it looked like hundreds of times for each call of Process_Data_From_Local_IO(). An easier, non-scope way would be to run a counter in the main while( 1 ) loop, then print it and reset it just before calling Process_Data_From_Local_IO().

...I was doing integer division in a few places in my joystick calculations and I was worried that my code was too slow, but was relieved to see that it runs in only 4 ms. Whew!
