[Machinekit] Re: Rpi3, Beagleboard X15, And Avnet Ultra96

[Claudio Lorini]

Nice and compact board, but i cannot understand the choice of removing 
wired Ethernet. 
Also missing CAN bus comms, so for 'usual' control applications a 
daughter-board is required 
and the somewhat limited IOs gets plundered even more...

[Machinekit] mklauncher "Can not find -sec DISPLAY -var INTRO_GRAPHIC"

[Cameron McQuinn]

Hi everyone,

I am trying to run a qtquickvcp-based config on my Snickerdoodle, but the 
launch fails. The linuxcnc_debug.txt file records the error "Can not find 
-sec DISPLAY -var INTRO_GRAPHIC". The config I am using is based of the 
ones created by MIchael Brown, and can be found in this 
 repo. I am trying to run the HAL 
Snickerdoodle config using the run.py python script. I am using the latest 
version of machinekit from the repo, and the latest version of QtQuickVcp 
compiled from source for armhf.

I was able to successfully start the config several months ago, but I had 
to set the project aside for a while. When I returned, I upgraded the 
kernel from 4.9 to 4.14, and upgraded machinekit and QtQuickVcp to the 
latest versions, but didnt' change anything else.

I have attached relevant log files, and am happy to provide more detail if 
necessary.

Thanks,
Cameron

[Machinekit] Re: Need help on pin mapping (BBB)

[Jeff Pollard]

Hi,

  There is a table here:

https://github.com/cdsteinkuehler/beaglebone-black-pinmux/blob/hal_pru_generic/pinmux.ods

  that shows how various pins can be assigned.

   The pin's drive capability seems to vary from pin to pin on the BBB, so 
you should probably check that to make sure it can drive your led in the 
opto.  Or just use a logic buffer to drive the opto.

Jeff

[Machinekit] Re: RPI gipo help

[KL Chin]

Hi Tim, 

I think the pin layout not correct as compare to the pins in hal_gpio.c

#rpi2_gpios[] = {2, 3, 4,  5,  6,  7,  8,  9, 10, 11, 12, 13, 14, 15, 16, 
17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27 };
#rpi2_pins[] =  {3, 5, 7, 29, 31, 26, 24, 21, 19, 23, 32, 33,  8, 10, 36, 
11, 12, 35, 38, 40, 15, 16, 18, 22, 37, 13 };

Can you verify it

  rpi2_pins   38, 40, 15, 16  should be  38, 15, 40, 16

Regards,
KL Chin

[Machinekit] Need help on pin mapping (BBB)

[Lang Gu]

Hello machinekit team and everyone 

I come from China,my english is very poor.So try to say as simple as 
possible. 
In China  It's no cnc cape available.So i try to make a 5 axis cnc cape for 
BBB.

Someone can tell me if this pin assignment is possible, or if there are any 
problems?
