Subject: [Emc-developers] New parallel port error message
Hello, all, merry Christmas and a happy new year!
I've got a user who downloaded the latest (looks like development head),
shows on screen
as 2.9.0, and he's using a PCIe parallel port at d010. He gets the following
message both in the log file
and on the Axis screen. 53264 decimal = d010 hex. The parallel port is
TRULY there, as
the system communicates with my PWM controller over it. So, the message is
totally
spurious. I have seen this on other systems but have just been ignoring it.
The message
"Linux parallel port" is not present in my hal_ppmc.c driver, it comes from
the code that
manages reserving the parallel ports. I'm pretty sure this message does NOT
come out
when using motherboard ports at 0x378. We specify the port address in the
loadrt command
line for the hal_ppmc driver.
Debug file information:
Note: Using POSIX realtime
PPMC: bus 0 epp_dir = 0
Linux parallel port @53264 not found
PPMC: bus 1 epp_dir = 0
PPMC: bus 2 epp_dir = 0
PPMC: checking EPP bus 0 at port D010
Thanks for any suggestions on how to get rid of this.
Jon
I think I have seen this when there is no Linux driver for the specific port
chipset. I agree its spurious since the Linux driver is not neccesary (at least
for chips that are standard enough that they dont need special setup)

(Fusion360 is partly why I lost the incentive to convert my G71 remap to native code) But a chamfer is easy to hand-code, and R-format arcs are simple too. I think that the objection to R-format falls down in lathe code where they are typically exactly 90 degrees. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 ___ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers
