Best of luck! let us know how it works, Last weekend, we finally got around to try and get everything working (and failed as far as EMC is concerned, but I will come back to that later - it just seems to be a configuration issue). The latency tests however looked quite fine. No overruns, no delays over 2ns (which is fine since we don't aim for BASE_PERIOD below 5). So at least it seems we don't need to replace the on-board video, which is good news. regards, Sven - This SF.net email is sponsored by: Splunk Inc. Still grepping through log files to find problems?

It looks like someone with the datasheet, one of these boards, and a basic knowledge of how to write HAL hardware drivers should be able to knock out a driver in a day. One example of a simple hardware driver for a made-up piece of hardware is shown in the docs: http://linuxcnc.org/docs/2.1/html/hal/comp/#SECTION00193000 another simple driver is one that allows use of certain "serial port" pins as GPIO: http://cvs.linuxcnc.org/cvs/emc2/src/hal/drivers/serport.comp?rev=1.4.4.1;content-type=text%2Fplain Jeff - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

Sven, you may want to boot the live cd and try the latency tests before going further. If the on board video can be defeated, try a pci video cardf and re-run the tests. Best of luck! let us know how it works. tomp - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML. No limits.

[Emc-users] Driver for Winbond W83627hf GPIO?
Hi. I'm implementing my machine control on a ALIX.1b board from pcengines.ch[0]. This board uses an AMD Geode LX and provides both a standard parallel port and GPIO pins (exported from the Winbond W83627hf Super I/O Controller). The driver for this chip in drivers/hwmon/w83627hf.c provides access to these GPIO pins. Any chance one could turn this into a driver which EMC² can support? The 256MB version of that board is currently available at around 100EUR, so this is a relatively cheap all-in-one PC (only needing a really small, passively cooled case and an external 12V supply, using only about 5 Watts), and with GPIO supported, parallel port+GPIO could drive even the more complex machines. The board exports a total of 21 GPIO pins (GPIO1 bit 0-7, GPIO2 bit 0-6, GPIO3 bit 0-5) from the Winbond chip. So this basically means a second (though more flexible) parallel port on board. Any idea how difficult it would be to make this happen? I have absolutely no (oh well, ok, about 2 hours hacking on some easy watchdog driver which had some reversed logic in it) experience hacking the kernel, let alone hacking on RTAI suitable drivers. Or is it already possible? if so: How?
