LawrenceG: the avr32 chips have audio and usb built in, and sample code as well.
mozmck, thanks... I have a high performance audio codec and I want to stream the data back into the pc.... the generic audio class looks promising... no pc side drivers needed
general audio class over usb? is your codec on a chip?
yea its a AD1871 chip by Analog devices.. stereo 24 bit 96khz a/d.... I could also write a custom image for a mesa card if I had a few years to learn vhdl :}... the pc is a pain to get data in and out of
in the isa bus days, a protocard and a few gates was all one needed
mind you the pc was so slow, one could not process the data
yeah, the avr32 is faster than the old pc!
LawrenceG: it looks like an AVR may not be a good choice for your project; I don't think they have clocked serial modes wider than 8 bits, but it looks like the AD1871 really needs one.
yea... 2.3Mb/s is beyond bit banging on most micros...
maybe a meas card interface is more reasonable... A header card for one of the 50 pin solts
Guest369 is now known as skunkworks
all of cia is down
but it seems they know about it, and when the datacenter gets back services should get restored.. no ETA so far
is there a deb for testing 2.4?
[18:36:03] <alex_joni> http://emc2-buildbot.colorado.edu/~buildmaster/
although the deb line isn't quite sane
I think it should be hardy v2.4_branch
maybe v2.4_branch-rt ?
the latter, I think
this is correct; at least, it's installing the package for me
oh, and I put the new hostmot2-firmwares in the 'base' repository on linuxcnc.org
I'm running the v2.4_branch-rt package on jr now, but I didn't figure out the firmwares yet
as soon as I get the Hardinge back on line I'll give them a try
cradek: $ sudo apt-get install hostmot2-firmware-5i20
your firmware should have the same name as before; but others, particularly people with cards that have two fpga sizes available, may differ
well maybe I do have that installed... I'll check later.
* jepler realizes he could easily use symlinks to make the hostmot2-firmware paths compatible with 2.3
hey all, back at the hobby after some time off working.
did a git pull update to emc2-dev, and noticed that there is only a 7i43 directory in /src/hal
what / where are the other mesa board files? like 5i20?
Roguish: it's actually a file
hm2_7i43 is for the 7i43
hm2_pci is for the pci boards, 5i20, 5i21, 5i22, etc
do we care about a temporary replacement for CIA?
alex_joni: not me
Roguish: the hostmot2 firmware images are moved to a new project, called hostmot2-firmware. In the emc2 tree the src/hal/drivers/mesa-hostmot2/firmware/7i43/CPLD directory is the only one left because this part hasn't been moved to hostmot2-firmware. (the CPLD is the chip on the 7i43 board which helps program the FPGA with the appropriate image, and then mediates the EPP communication. Most users never reprogram the CPLD; the so
if you used a symlink in /lib/firmware to your emc2 git checkout to get firmwares for the hostmot2 driver, then you'll have to do something extra now (such as install the new hostmot2-firmware packages through apt-get)
apt-get install hostmot2-firmware-7i43-2 or hostmot2-firmware-7i43-4 depending on the size of FPGA you have (the old S / B in the firmware name), then look in /lib/firmware/hostmot2 for the new firmware name
(in the case of the 5i20 I think all the firmware names are the same..)
jepler: your patch about [Emc-developers] [PATCH for v2.3.x] paper over a memory leak could I also apply this on 2.5-dev ?
ries: the code is a bit different in master; I think the patch didn't apply without modification.
the leak exists in master, so some version of the patch should be made there if it tests right
jepler: I applied it manually...
problem is I get this error during startup of EMC : AttributeError: MyOpengl instance has no attribute 'g'
at the line that states : if o.g is not None:
yes, I think the name 'o.g' is different in master, but I don't have the source code in front of me to check. it *might* be called o.canon in master.
I will check that...
It's indeed o.canon
