If it makes you feel any better, I didn't install vim by default and curse the system every time I start with a new image, go to edit a file, and find half the key commands I'm used to don't do the right thing!

2013/12/29 Charles Steinkuehler char...@steinkuehler.net Now that's cool!!! Thanks! What happens when it freezes? Are there any error messages on the serial console port? I haven't paid much attention... Sometimes it just froze and the mouse did not move (but that could be a power surge). Sometimes it happened when I moved the joint, it slowed down but did not stop when I was pressing Esc or whatever, then the BBB rebooted. And so on. It usually froze under load. Actually genhexkins takes more CPU resourses, so Axis preview is very slow, I mostly switch to DRO tab. I use standalone BBB, by the way.

Re: [Emc-users] More stepgens with BeagleBone
2013/12/21 Charles Steinkuehler char...@steinkuehler.net Yes, you can run stepgens on both PRUs...you'll just have to tweak the HAL module to support this. It's on my list of things to do some day, but it's not real urgent. The good news is you almost certainly don't need to run code on both PRUs to do what you want. If you are not seeing step/dir signals on the newly added I/O pins, you probably have something simple wrong. Some things to check: * You are using the pins assigned to the on-board HDMI/LCD output. You have to make sure you disable *BOTH* of the HDMI capes (BB-BONELT-HDMI and BB-BONELT-HDMIN) or you won't be able to use these pins. * You need to make sure the pins are setup for GPIO output. This is done in the setup.sh script called at the start of the hal file. Edit as appropriate to add your pins to the list and make sure the direction is out. * To test, before you run LinuxCNC, manually run the setup.sh file and then see if you can toggle the GPIO pin values normally. Note you need to use the kernel pin numbers in setup.sh (above) and for gpioN (below): echo 1 /sys/class/gpio/gpioN/value echo 0 /sys/class/gpio/gpioN/value ...if the I/O pin doesn't 'twiddle', you don't have the BeagleBone setup properly. If it does, LinuxCNC and the PRU code should be able to talk to it. If it's still not working, double-check the pin setting in HAL (which you can change at runtime with halcmd). The HAL pin setting should be the kernel number (from above) + 32. Thank you! I chose other pins and added them to sh script, now it works.

Is it possible to run stepgens on both PRU0 and PRU1? Yes, you can run stepgens on both PRUs...you'll just have to tweak the HAL module to support this. It's on my list of things to do some day, but it's not real urgent. The good news is you almost certainly don't need to run code on both PRUs to do what you want. If you are not seeing step/dir signals on the newly added I/O pins, you probably have something simple wrong. Some things to check: * You are using the pins assigned to the on-board HDMI/LCD output. You have to make sure you disable *BOTH* of the HDMI capes (BB-BONELT-HDMI and BB-BONELT-HDMIN) or you won't be able to use these pins. * You need to make sure the pins are setup for GPIO output. This is done in the setup.sh script called at the start of the hal file. Edit as appropriate to add your pins to the list and make sure the direction is out. * To test, before you run LinuxCNC, manually run the setup.sh file and then see if you can toggle the GPIO pin values normally. Note you need to use the kernel pin numbers in setup.sh (above) and for gpioN (below): echo 1 /sys/class/gpio/gpioN/value echo 0 /sys/class/gpio/gpioN/value ...if the I/O pin doesn't 'twiddle', you don't have the BeagleBone setup properly. If it does, LinuxCNC and the PRU code should be able to talk to it. If it's still not working, double-check the pin setting in HAL (which you can change at runtime with halcmd). The HAL pin setting should be the kernel number (from above) + 32. -- Charles Steinkuehler char...@steinkuehler.net signature.asc Description: OpenPGP digital signature -- Rapidly troubleshoot problems before they affect your business.

[Emc-users] More stepgens with BeagleBone
Hello, I'm trying to set up BeagleBone using Charles' image (with HDMI display). As I do not have any cape board I simply connect A4988 drivers to BBB's output pins. K9.HDMI config has 4 stepgens, but I'd like to have 6 or 7. It loads with num_stepgens=6 but the question is which output pins can I use for two or three extra stepgens?

It loads with num_stepgens=6 but the question is which output pins can I use for two or three extra stepgens? Any I/O pins that are not already used by something else. The PRU code is capable of driving any pin in the 4 32-bit banks of GPIO, as well as the 16 directly-connected low-latency PRU output pins. To calculate a pin number to use for the GPIO banks: Pin# = ((gpio_bank + 1) * 32) + pin_number ...this is the same as the kernel pin numbering scheme, except one is added to the GPIO bank so that zero results in an invalid pin number and means don't drive any pin. This is to keep things safe since all pin numbers default to zero the way HAL shared memory gets initialized, you have to explicitly set a pin number before the PRU actually tries to twiddle something. -- Charles Steinkuehler char...@steinkuehler.net signature.asc Description: OpenPGP digital signature -- Get 100% visibility into Java/.NET code with AppDynamics Lite!
