You probably dont need all those debug flags enabled. It wont hurt anything, but it will spew a bunch of stuff you dont care about to the logs at startup. > # load low-level driver > loadrt hm2_pci config="firmware=hm2/5i20/SVST8_4.BIT num_encoders=4 > num_pwmgens=4 num_stepgens=0" > > #load threads > loadrt threads name1=tt period1=10000 name2=tt2 period2=1000000000 10,000 ns is a *very* fast thread. Below you add a lot of stuff to it, so i'm guessing your machine becomes pretty unresponsive when you run this hal file. 100,000 or 1,000,000 is more typical. > #naložimo pyvcp ter počakamo da se le ta zažene > > loadusr -Wn iotest pyvcp -c iotest iotest.xml > > addf hm2_5i20.0.read tt > addf hm2_5i20.0.write tt > > addf hm2_5i20.0.read_gpio tt > addf hm2_5i20.0.write_gpio tt > addf hm2_5i20.0.pet_watchdog tt Since you have the .read and .write functions in this thread, there is no need to have the .read_gpio and .write_gpio functions. .read reads everything and .write writes everything, including gpios. The .read_gpio and .write_gpio functions were added so that people who wanted to read *just* the gpios could do that (for example, for probing in a fast thread). > setp hm2_5i20.0.watchdog.timeout_ns 10000000 The longest watchdog timeout is just over 4 seconds. 1 second should be plenty.

The effective range of duty cycle is from -1 to +1. So with this configuration, any value on the .value pin greater than 1.0 will result in 10V output from the 7i33. A value of 0.5 should result in 5V being output, etc. Is that not what you're seeing? -- Sebastian Kuzminsky any sufficiently analyzed magic is indistinguishable from science ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
