[01:33:13] <andypugh> Argh! One of these days I will remember how to push a commit without a random trivial merge.

[02:01:16] <uminded> when I start my hal thread running any idea why my function is being called on time but 27 times in a row on time??
[02:03:35] <andypugh> I don't understand the question.
[02:08:58] <uminded> I have my function added to a thread counting at 100ms. Every 100ms that function is called 27 times in a row
[02:09:18] -!- asdfasd has quit [Ping timeout: 245 seconds]
[02:09:46] <andypugh> That seems a bit random
[02:10:08] <uminded> indeed, yet its always 27 times even when I restart halrun
[02:13:15] <andypugh> How are you measuring that it is called that many times?
[02:13:31] <andypugh> Is it possible that there is a loop in the code?
[02:14:54] <uminded> the code is a simple if/else and thats all. I have a printf in there and its output 27 times

[03:17:11] <uminded> Are their any latency tests that do not require a display? I can only run my xenomai latency test app but not latency-test
[03:18:35] <andypugh> there is a text mode one somewhere in the RTAI folders
[03:19:20] <pcw_home> is the xenomai test a text app?
[03:19:35] -!- tjb1 has quit [Quit: tjb1]
[03:20:01] <uminded> yup,
[03:21:51] <uminded> pcw_home:
http://pastebin.com/3kYDWVJJ here are my xenomai numbers under load. I don't know how to imply step speed from them though
[03:24:53] <andypugh> well, 10k latency hints that your base thread can't really be faster than 20uS.
[03:26:23] -!- Wildhoney has quit [Ping timeout: 256 seconds]
[03:28:11] <uminded> This is just our inital port of xenomai, we have a team member that has been able to get the worst cases down to ~5.5
[03:30:21] <andypugh> 20k is fine. That's 50kHz
[03:30:52] <andypugh> (that's 20kilonanoseconds ugh)
[03:33:17] <uminded> our goal was to output a minimum 31kHz train reliably with a 50kHz being an awesome if situation
[03:33:33] <andypugh> I wonder what finishing process they use on the machined-from-solid Macbooks? I just spent several hours filing/sanding/polishing some as-machined parts from my mill.
[03:34:02] <uminded> with our latency fixes in the kernel we should be smooth sailing to drive a machine with our boards gpio!

[05:43:50] <uminded> is their a way to initilize a whole string of gpio all at once instead of one at a time with int hal_pin_bit_newf() ?? I have 288 GPIO to export and that would be 288 ints this way instead of just 9 32bit words

[15:05:48] <jepler> the hal type should be hal_bit_t, otherwise it's not suitable for hooking up to the types of signals you might transport on gpios, like limit switche inputs or enable outputs
[15:06:04] <jepler> the one bit of code you've pasted to the channel shows you were using a literal number to create your pins .. just use a for-loop
