[00:00:58] <FinboySlick> A2Sheds: When can I buy? ;)
[00:02:20] <Valen> the problem is because the device is then connected to mains it has to presumably go through mains rated safety
[00:02:25] <Valen> double insulated everything etc etc
[00:03:26] <A2Sheds> FinboySlick: boards start shipping this month, the factory in China is just getting back up after the spring festival

[00:06:58] <A2Sheds> FinboySlick: 4GB flash
[00:07:13] <FinboySlick> A2Sheds: Wow, then it's absolutely perfect.
[00:07:31] <A2Sheds> the 68 pin connector supports SATA
[00:10:19] <FinboySlick> A2Sheds: Got that. What's to be expected cost-wise?
[00:16:35] <A2Sheds> FinboySlick: once it ramps up $25-35/card with the A10, the AMD APU version will be equivalent to a similar mainboard price
[00:17:01] -!- The_Ball [The_Ball!~The_Ball@] has joined #linuxcnc
[00:17:37] <FinboySlick> Is there an FPU on the A10?
[00:18:46] <FinboySlick> Nevermind, just figured out you meant Cortex A10 ;)
[00:18:49] <A2Sheds> yes, it's an ARM cortex a8 1.2GHz
[00:19:16] <A2Sheds> http://rhombus-tech.net./allwinner_a10/
[00:19:46] <A2Sheds> Luc Verhagen is releasing open drivers for mali as well
[00:20:13] <A2Sheds> http://www.phoronix.com/scan.php?page=article&item=arm_mali_reverse&num=1
[00:20:36] <FinboySlick> That would be important to my *other* project :)
[00:20:51] <A2Sheds> I might have a version of the card with an FPGA to interface to mesa IO cards
[00:21:41] <FinboySlick> Actually, all I need is something capable of booting linux with 8-10 GPIO and an USB connector.
[00:22:17] <FinboySlick> And an FPU.
[00:22:25] <A2Sheds> the FPGA version would also have a DDR3 NAND drive (ddr3 behind the NAND interface to be used as fast swap)
[00:23:00] <A2Sheds> yes, it covers those requirements
[00:23:22] <A2Sheds> #arm-netbook is that channel
[00:23:28] <FinboySlick> It's simple enough that I'm begining to wonder if I could run it all off an FPGA.
[00:23:57] <FinboySlick> Hmm...
[00:24:08] <Valen> FinboySlick: rasberry pi?
[00:24:29] <A2Sheds> uclinux has been running on xilinx and other FPGA soft cpu's for a while
[00:24:30] <FinboySlick> Valen: Well, it seemed like a cheap platform for what I'm trying to do, but even that has lots of extras that I don't need.

[00:54:59] <sliptonic-shop> I'm configuring a new computer to drive my cnc router and laser. I get max jitter numbers around 9700 on the base thread but unless my base period is set at 34000 or greater I get the RTAPI unexpected delay error.
[00:55:33] <sliptonic-shop> This is way worse than the old P4 machine with similar max jitter numbers. Any idea where to start looking?

[01:22:37] <Valen> sliptonic-shop: its not uncommon to have a single latency spike when starting openGL
[01:22:54] <Valen> run your latency test, then start glx-gears
[01:23:03] <Jymmm> What it is after 24H is what matters.
[01:23:05] <Valen> if you get just the one spike its probably ok
[01:23:21] <Valen> just don't start any openGL apps ;->

[02:13:56] <sliptonic-shop> Valen Jymmm I've left the machine for 24 hours at a stretch and I see pretty consistent numbers around 9700 - 10000. But I get the RTAPI message every time I launch emc and home it. It's just that the latency numbers are so different from what I have to put in for base thread that has me confused.
[02:14:25] <Valen> sliptonic-shop: did you start glx-gears *after* latency test?
[02:14:45] <sliptonic-shop> Yes. 6 or 8 copies.
[02:15:52] <Valen> you got no spike when you started glx?
[02:16:20] <sliptonic-shop> No. Not really.
[02:16:35] <Valen> you can look at latency within axis as well
[02:16:50] <Valen> theres some thing you can perhaps plot
[02:17:02] <Valen> forgot what its called
[02:19:23] <sliptonic-shop> Something in Halscope?
[02:20:09] <Valen> yeah
[02:20:22] <Valen> one of the things you can scope is latency or something like that
[02:20:26] <Valen> i forget its actual name

[02:54:12] <Jymmm> or guberment surplus
[02:55:23] <cstop> Everything I have is at least ten years old ;-) I like old stuff!
[02:55:58] <cstop> ya know ya can't buy 'em like this any more
[03:01:13] <skunkworks> Is there no i/o on 7I78
[03:06:28] <skunkworks> no
[03:17:18] -!- cmorley has quit [Ping timeout: 252 seconds]
[03:20:25] <cstop> it takes an additional serial card to add I/O
[03:51:16] <pcw_home> or just the other port if 17 TTL I/O is enough
[03:54:59] <mikegg> http://www.reddit.com/r/LinuxCNC/
[03:55:06] <mikegg> anyone else a reddit junkie ?
[03:57:40] <jdhNC> I thought reddit was porn
[04:00:32] <mikegg> eh, there's other stuff too
[04:03:47] <mikegg> pictures of cats, and atheists
[04:08:14] <skunkworks> pcw_home: oh - didn't think of that...
[04:11:30] <pcw_home> or any standard parallel port type breakout if you want isolation/ buffering or whatever
[04:11:56] <skunkworks> pcw_home: that is a very cool product..
[04:14:08] <pcw_home> I should have done it sooner, I was afraid the PCI stuff would be too hard but it was pretty easy
[04:15:23] <Valen> pcw_home: pci stuff?
[04:15:34] <pcw_home> PCI core
[04:15:52] <Valen> inside a fpga?
[04:16:50] <pcw_home> Yes part of hm2 for 5I25 like cards that have no bridge chip
[04:17:24] <Valen> nice
[04:17:38] <Valen> pci has always scared me electrically, and now pci-E just makes it insane
[04:18:07] <pcw_home> Tradeoff is you cannot bootstrap a un-programmed FPGA card except via JTAG
[04:18:37] <Valen> bit of a pain
[04:18:48] <Valen> parallel port jtag wiggler? ;->
[04:20:05] <pcw_home> But the Spartan 6 has multi-boot capability so even if you pull the plug while writing the EEPROM you are OK
[04:20:07] <pcw_home> (yes a parallel port wiggler will do)
[04:20:25] <Valen> multiboot is handy
[04:20:38] <Valen> I have always wanted to play with fpgas
[04:20:50] <Valen> i always seem to want bunches of PWM's
[04:21:02] <pcw_home> should only need JTAG if you make a pretty bad mistake or 2 mistakes in a row
[04:21:03] <Valen> and doing that with micros gets irritating
[04:21:41] <pcw_home> PWM gen is small enough Im sure you can have 1 per pin if you need it
[04:21:57] <Valen> i also want small and cheap
[04:22:14] <Valen> for one app I want 7x PWM's with deadtime
[04:22:18] <Valen> ideally ;->
[04:22:34] <Valen> including the fets and a radio , in the size of a matchbox
[04:23:14] <pcw_home> FPGA are not really cheap unless you have high volumes (and need funny power supplies)
[04:24:08] <Valen> thats always been the barrier to entry for me
[04:24:11] <pcw_home> probably some couple of $ DSP is the best bet
[04:24:27] <pcw_home> some have 8 or more PWMs
[04:24:31] <Valen> they don't seem to have the deadtime generators though
[04:24:45] <Valen> that only seems to come from motor controllers
[04:24:59] <Valen> and they don't often have more than 3 or 4 PWMs
[04:25:16] <pcw_home> 7 PWMs with highside/lowside/deadzone?
[04:25:32] <Valen> that'd probably do i spose lol
[04:25:42] <Valen> I like the micros with FPGA around them, never used one though
[04:26:15] <pcw_home> Some of the PICs we use have 8 PWMs but they may only have 4 if you need h/l/d
[04:26:30] <Valen> yeah, thats what i've been seeing
[04:26:59] <pcw_home> also they have the high res PWM (960 MHz)
[04:27:12] <Valen> mhz? or khz?
[04:27:32] <Valen> I'm only after ~10khz max
[04:27:37] <pcw_home> but its really only good to 480 MHz (thats the basic clock)
[04:27:57] <Valen> you sure your not adding a 0 or an M to those numbers?
[04:28:14] <Valen> 96mhz in a pic i can just about see ;-.
[04:28:21] <Valen> 960mhz?
[04:29:02] <pcw_home> no thats the PWM clock so ~9 bit PWM at 1 MHz 12 bit at 125 KHz
[04:29:40] <Valen> yeah, i just still wouldn't believe any component in a pic running at ~1ghz
[04:29:53] <pcw_home> PLL
[04:30:06] <Valen> i have avr pwm running at 60+ mhz for pwm stuff
[04:30:33] <Valen> got a part number on one of those handy?
[04:30:39] <Valen> got me all curious now
[04:30:55] <pcw_home> deliberately done for Hi res PWM ( older chips ran PWM at CPU clock so 40 MHz or so)
[04:30:57] <pcw_home> TI also does this
[04:31:10] <Valen> oh i've seen it done
[04:31:13] <Valen> i've even used it
[04:31:20] <Valen> that avr had a core clock of 16mhz
[04:31:26] <Valen> pll for pwm clock
[04:32:42] <pcw_home> DSPIC33FJ16GS502
[04:32:54] <pcw_home> for example
[04:36:41] <pcw_home> TI has a 5.5 GHz equivalent PWM frequency (180 ps steps) (and maybe more on some chips)
[04:37:09] <Valen> I'm guessing they cheat somehow
[04:38:10] <Valen> some kind of skewed clock doohickey
[04:38:14] <pcw_home> They do, its some kind of analog delay imterpolator or some such
[04:39:36] <pcw_home> kind of like Xilinx's DLLs which are just a tapped ring oscillator
[04:39:40] <Valen> how many macrocells would a pwm use ?
[04:40:06] <Valen> roughly
[04:40:38] <pcw_home> You can make a really tiny one with SRL16s so you could have 1000s in a decent sizedFPGA
[04:41:15] <Valen> just browsing through the cheap section of them in my suppliers catalog
[04:41:22] <Valen> anyway i must get some work donw
[04:41:30] <Valen> thanks for the heads up
[04:41:34] <pcw_home> the one in HM2 uses a common reference counter and comparators
[04:42:19] <pcw_home> its not too big either so the smaller FPGA will easily fit more than you are likely to need
[04:42:36] <Valen> I wonder about doing the rest of the code in it
[04:42:41] <pcw_home> s/smaller/smallest/
[04:42:44] <Valen> i spose i could make it pretty simple
[04:43:00] <Valen> so just radio > fpga
[04:43:42] <Valen> theres usually some slightly complex stuff involved, and a brushless motor controller, but that shouldn't be too hard
[04:44:14] <pcw_home> you can put maybe 8-10 8 bit 133/150 MHz processors in a very small FPGA
[04:44:17] <pcw_home> (XC6SLX4)
[04:44:46] <Valen> those might be physically small
[04:44:57] <Valen> but pretty spendy and bga?
[04:45:02] <pcw_home> We would normally use a DSP for that cost wise
[04:45:25] <pcw_home> FPGA will be maybe $7 vs 3 and needs 1.2V
[04:45:54] <Valen> do they have higer voltage IOs?
[04:46:24] <pcw_home> But if you need custom/flexible I/O the FPGA wins
[04:46:43] <Valen> I'll probably just use 2x AVRs
[04:46:51] <Valen> one for 2x brushed motors and 1x for the brushless
[04:46:57] <pcw_home> No newer FPGAs are 3.3V only or even 2.5V
[04:47:14] <Valen> not going to direct drive fets off that
[04:47:40] -!- WalterN has quit [Quit: Leaving]
[04:48:25] <pcw_home> FPGAs are also nice in that you can tailor the peripherals to your needs (if we had to do what SSLBP does with standard UARTS we would have given up)

[13:09:12] <awallin> yeah, southern finland is close to the sea, so that stabilizes things a bit. if you are inland with no sea close it can get really cold. They had -35C up north I think.. next week it's supposed to be "warm" -10C again

[18:26:22] <mikegg> ahhhhh pcw_home: thank you for making such awesome hardware! I'm finally able to get a good tune on my servos
[18:27:10] <mikegg> with those +/- 10 VDC analog drives, you couldn't tune them for shit. I think they are really sensitive to noise. any D-gain and they become unstable
[18:28:18] <mikegg> I love this 7i39. rock solid
[18:29:42] <Jymmm> mikegg: You forgot the "pcw, YOU'RE MY HERO! <rapid blinking of eyes goes here>"
[18:29:54] <mikegg> hah
[18:30:08] <Jymmm> =)
[18:30:40] <pcw_home> Well crude old voltage mode PWM has one nice redeeming virtue: inherent high frequency damping damping
[18:31:22] <skunkworks> I am using +/-10 drives with great results. (but Also mesa interface hardware so maybe that is the magic ;) )
[18:31:40] <mikegg> are they torque mode?
[18:32:05] <skunkworks> took 2 tries to hook the the mesa connected to the drive without noise issues.
[18:32:05] <mikegg> I got the best results in torque mode, but they had a deadband around zero
[18:32:12] <pcw_home> Torque mode drives are a bear to tune without a pretty high servo thread rate
[18:32:14] <Jymmm> Magic? That would explain the chicken bones and eye-of-newt invoice I saw on mesa's website.

[20:05:38] <kirk_wallace> Hello, I'm trying to get Modbus working on my SJ200 VFD . Using modpoll I can read coils, which start at address 0x01, but I can't read registers. The manual shows addresses for registers, but apparently, these are indexes to the register block start, which is not stated in the manual. I searched for other information and found an app note that indicated the registers start at 40001, but modpoll returns an illegal address error from the SJ200.

[20:25:15] <wendtmk> You shoulda seen the software updater when I turned my computer on for the first time in a number of months. About 200 MB of software updates, including v2.4.7 of uh, linuxCNC... ;-)
[20:25:49] <wendtmk> We got any HAL guys onboard today?
[20:28:49] <mrsun> gah put some set screws on the base of the mill to ease tramming it ... yeah right ...
[20:28:58] <mrsun> cant get it trammed however i do it :/
[20:30:00] <skunkworks> just ask
[20:31:55] <skunkworks> wendtmk: what project are you working on?
[20:32:25] <kirk_wallace> I'm looking for help with modbus on an SJ200 VFD. I asked about a half hour ago, but can repost.
[20:33:19] <wendtmk> Welp, with the upgrade to 2.4.7, a a HAL Pin that had worked up to today no longer works. In my custom_postgui.hal file, I've got the config set for both an MPG and a joypad. No problems with the MPG, but this line: "net remote-speed-slow or2.0.in0 input.0.btn-trigger" now causes EMC2 to barf on startup, with this error: "custom_postgui.hal :87: Pin 'input.0.btn-trigger' does not exist
[20:34:06] <wendtmk> Ah, this is my CNC saw beveler that I've had up and running for a while now.
[20:35:19] <wendtmk> So, did the btn-trigger pin get deprecated in one of the last few releases? I don't remember what release I had on before it got upgraded yesterday to 2.4.7
[20:35:42] <skunkworks> wendtmk: yes - a pin changed depending on how linux enumerated it.. (or something like that)
[20:36:06] <wendtmk> Forgot to mention, if I comment out that line, EMC2 starts up just fine.
[20:36:39] <skunkworks> so - start linuxcnc with it commented and look at the pin list.
[20:36:53] <skunkworks> it is the trigger name that changed iirc
[20:37:19] <cpresser> perhaps you need to change the hal component from hal_joystick to hal_input
[20:37:54] <cpresser> but most likely linuxcnc wouldnt start if you tried to load a nonexistent module
[20:38:20] <wendtmk> All right, give me a few and I'll start it up with that pin commented out
[20:40:00] <mrsun> oh ive been doing it wroong .... how nice :P
[20:40:51] <mrsun> oh well, you live and you learn =)
[20:41:41] <wendtmk> Yeah, it's the trigger name, but I'm not sure which one is the one that replaced it looking at the HAL btn-*
