After this, the analog pins worked as expected: ADC always works, no matter which overlay you used to switch the PRUSS on.

[beagleboard] New BeagleBone Black Metal Enclosure
I've read topics on this board in the past and have dabbled with the BeagleBone Black and love it as a device. We decided to develop a new innovative enclosure for the BeagleBone Black and we have. This is our launch weekend. Anyone who uses the code ZRH22XCW will get 30% off starting tomorrow morning. Check it out and let me know what you think: http://www.amazon.com/gp/product/B00VKM2I5W This is the only enclosure that has cable management built into it. There are several mount types available: DIN rail, magnetic (comes with 3 magnets installed), thru hole.

[beagleboard] Re: Best node performance for an expressjs app
Haven't run your code on mine (and what I'm going to say is all
theoretical) but you'd need to ensure your tcp stack is optimised to
minimise latency even when using a loopback interface. You still have the
overhead of TCP (congestion control, flow control, stream management, IP
packet ordering, retransmission, etc).
I wouldn't have expected the beaglebone to be significantly worse/better in
this respect.
This article is quite
nice http://techblog.netflix.com/2014/11/nodejs-in-flames.html and so
perhaps we could use some of that to profile what's going on within Node.js
itself.

Re: [beagleboard] No HDMI output on beagleBone Black
Yes, I recently went looking for an hdmi - vga converter and most are passive types in stores like Fry's electronics. Where the active ones run like ~$50. Even on amazon they seem to start at around $34, and no guarantee that they'll work for every device.

VGA to Micro HDMI connector. and just noticed ^ Yeah, unless you paid lots of $, it's probably a passive cable, in which case that's not supported. With HDMI, there shouldn't be passive adapters as HDMI is digital only. DVI-I has both. EDID can often be an issue with these adapters. ATi use to have some passive adapters in the wild, i've seen where the video card will detect their custom hdmi cable and pass vga signals thru it.. There are a lot more active hdmi - vga cables now on amazon too... But they must be externally powered, as the bbb can't supply enough power on it's own thru the hdmi port. http://www.amazon.com/Cable-Matters-Active-Female-Adapter/dp/B008O7RH5C As long as they properly pass the i2c bus used for edid read's, the bbb should detect the vga screen.

Re: [beagleboard] Bone-tester board information available?
Tester is for production use only that runs all the test scripts automatically without a lot of user intervention. This information is not made public.
