Re: [beagleboard] Re: Octoprint
Feel free to update the wiki article. I wrote it originally but I switched my OctoPrint server to the RPi eventually because it's more common.

[beagleboard] Connect Through MiniUSB
I helped write those instructions. Before you try to get the whole OctoPrint system going I'd get familiar with the plain BeagleBone first. Start with the recommended image from BeagleBoard.org and connect to that and get familiar with it first. Full disclosure, I switched over to a Raspberry Pi2 using the OctoPi image. Those instructions were for what is an old Wheezy image nowadays and may need some tweaking if used with a newer Wheezy or Jessie image. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.

[beagleboard] Re: Poor Java performance on new BBB
Wish I could help with that but I'm not that good with core Linux stuff. I just noticed that your kernels and java versions with different and in my experience that could explain the performance difference. Maybe someone more experienced could tell you how to backup the eMMC to a SD card. If you could do that you could swap the whole core image from the fast BBB to the other to see if it fixes the problem (after backing up both images first).

[beagleboard] Re: Poor Java performance on new BBB
Both your kernel and Java versions are different. I would try running the same Kernel and Java version from the fast BBB on the slow BBB (or better yet the exact same OS image).

Re: [beagleboard] Driving LEDs
Thanks. Between you and Gerald I think I have it. Don't worry, I'm using a 10K current limiter at 3.3V for now but yes I will start adding a driver transistor. I was just wiring it the way the BoneScript example except that I only 10K resistors handy as opposed to the 470 the tutorial called for. Actually kinda surprised my LED lights at all since I reduced the current down to .33mA from the 7mA in the original circuit on BeagleBone.org -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.

[beagleboard] Driving LEDs
Is there a reason a particular reason that the LED examples connect the current limiting resistor to GND and light the LED with a logic high state on the pin? I'm more used to TTL open collector where the current limiter goes on VCC and you drive the pin low. Are the GPIO pins on the BBB able to provide the same current in both states?
