[07:25:36] <jepler> >>> c.mdi("G0X[0*%f]" % 1e300)
[07:25:39] <jepler> ValueError: MDI commands limited to 254 characters
[08:30:30] <skunkworks> 117k over night (58us)
[08:42:37] <skunkworks> The servo thread is 170k clocks 85us
[09:09:36] <skunkworks> pcw_home, what kernel are you using?
[10:09:08] <pcw_home> 4.1.15-rt18
[10:18:58] <skunkworks> pcw_home, http://imgur.com/QI4tcHH
[10:19:45] <skunkworks> 19us?
[10:20:15] <skunkworks> I wish that hd would boot on the j1900
[10:20:24] <skunkworks> to try
[10:21:09] <pcw_home> what hardware are you using?
[10:21:26] <skunkworks> none at the moment.
[10:21:31] <skunkworks> sim
[10:22:03] <pcw_home> I built a 4.4.1 kernel on the G3258 and it does work well so my problems with 4.4 are later
[10:23:00] <pcw_home> by hardware I meant what CPU but I see it there
[10:24:22] <skunkworks> yesterdays/this mornings numbers are from the j1900. That screenshot is from the i5 hp
[10:27:47] <pcw_home> Yes I get about only about 20 usec worst case on the G3258 so its quite variable
[10:32:16] <skunkworks> Those i5's hp's seem pretty nice for realtime
[10:33:05] <skunkworks> I have not tried the ethernet port yet
[11:14:59] <JT-Shop> what could make a hostmot stepgen count not change when it is enabled and the position cmd changed? the stepgen has scale and step/dir and max vel/speed set
[11:46:52] <JT-Shop> axis, motor and stepgen fb all show 0 when I jog... what am I missing?
[11:55:42] <JT-Shop> nevermind i fingered it out
[14:33:13] <JT-Shop> 5i25 flashed with 5i25_prob_rfx2.bit how do I get pin 15 on p3 to be an output?
[14:35:19] <JT-Shop> the pin file shows 15 3 IOPort None
[14:37:55] <PCW> you need to setp the GPIO is_output attribute
[14:38:43] <JT-Shop> ok, gpio.003 is pin 15 on p3 right?
[14:39:09] <PCW> yes
[14:40:15] <PCW> so something like
[14:40:16] <PCW> setp hm2_5i25.0.gpio.003.is_output true
[14:42:36] <JT-Shop> bit OUT FALSE hm2_5i25.0.gpio.003.in
[14:42:43] <JT-Shop> bit OUT TRUE hm2_5i25.0.gpio.003.in_not
[14:42:50] <JT-Shop> bit RW FALSE hm2_5i25.0.gpio.003.invert_output
[14:42:57] <JT-Shop> bit RW FALSE hm2_5i25.0.gpio.003.is_opendrain
[14:43:08] <JT-Shop> that's all the pins and parameters for 003
[15:08:14] <PCW> are you sure you have the right bitfile loaded? (and power cycled or --reloaded after flashing the card)
[15:52:47] <JT-Shop> actually I'm sure I don't have the right bit file lol
[15:53:44] <PCW> do you know the --reload mesaflash command?
[15:53:52] <JT-Shop> I was testing the config on my plasma with 7i76x2.bit :(
[15:55:27] <JT-Shop> yes, I was trying to convert a parallel port stepper config for the guy and was just checking to see if it worked, I'll flash it and proceed
[15:55:34] <JT-Shop> no wonder I got confused
[16:16:29] <JT-Shop> must be time to start drinking lol
[16:19:42] <PCW> yep the 7i76 config is going to act a bit differently...
[16:25:58] <jepler> The drone ship "Of course I still love you"
[16:26:14] <jepler> anyway looks like spacex has done their first successful ship landing of the stage 1 today
[17:47:01] <seb_kuzminsky> jepler: as you no doubt know: https://en.wikipedia.org/wiki/List_of_spacecraft_in_the_Culture_series
[17:49:20] <seb_kuzminsky> they should name the next one after a Zetetic Elench ship
[18:03:37] <jepler> seb_kuzminsky: :)
