no, im interfacing a magnostrictive linear position sensor, and since its a word value and i want to be able to have it position a moving head in realtime after doing the calculation for converting inches to position.. ie i want the head to drop 9/16 " for a 1/2" board starting with a 20"  high block of wood...... save me figuing out that stuff

there is a addon mod that i could get for the sawmill that does the job, but its $1500 and since the sawmill is a hobby now, and i have manufactured hydraulic componets for it, i thought i would just play with making this componet....

so far i have got it to work with the sensor, and with the UM-FPU using spi ( still having trouble with some of the functions ) now i'm going back and doing the keypad to enable me to enter commands

precision with that sensor is like 2200 counts ( roughly) for 24 inches, right now im using to the 1/16th of a inch, could go to 1/32 but the mill doesnt need that precision yet.. using the timer on the sx48 btw..

anyways,  thats what im playing with currently, just got in the ic2/uart eval board and musing on it  :p
