Re: [beagleboard] Re: LCD 3.5 Cape Blocks all Analog Input Pins on Beaglebone Black
I think you are going to have to use an external ADC. The good news is that you can get better accuracy and a lot higher resolution by doing so. At the expense, of course, of some additional cost and complexity. I ended up using an ADS1115 from TI that delivers 16bits of resolution at 800 samples per second. BUT, another big but, is that I used an Arduino Nano as a front end to my BBB as I found it easier to integrate the Nano and the BBB than the ADC and the BBB. I am using Node and the libraries that do I2c were not working for me. You may have different luck depending on your environment.

Re: [beagleboard] Beaglebone Black won't power on, did I do something wrong? :(
Gerald, who responded to my message, will likely respond to you as well. The BBB is a great board but it does seem to be very susceptible to getting fried. I have had two visit the Beagle Hospital. I can only suggest that posting here in hopes that Gerald gets back to you... Regards, Will On Mon, Jul 7, 2014 at 10:55 AM, venkat@gmail.com wrote: Hey Will, I too face same problem on my BBB.

I know that I may have been careless but a board that could get used like an Arduino (which is very very robust) seems like it needs more protection than the BBB has at the moment. In any case, further on the story of a BBB with a blown processor. I am in the UK and have bought my boards from Element 14. You mentioned that you thought they would be able to send a BBB in for repair but when I talked to them they did not think they had this capability. I now have two boards that I have managed to fry. The most recent one as a result of a lead dragging across the battery on a Real Time Clock module with all other power being off. If they can be repaired for less than the cost of a new board I would be glad to pay. I can get the boards to the US as I suspect that will be easier. Can you let me know if they can be repaired at reasonable cost? If so I will request RMAs. Thanks, Will On Thursday, 4 July 2013 15:38:46 UTC+1, Gerald wrote: You have blown the processor.

When I plug it into a power source, be it a known good 5v supply that I have been using with it for weeks, or into either of two computers via USB, I get one dim little flash from the power LED and then NOTHING else. No other lights flash. If I hold down the power switch I will get another brief and dim flash after a couple of seconds. Again, no other LEDs light and nothing else happens. This started to happen when I plugged the BBB into a computer using a USB cable while it was still plugged into the 5V power source. Could this have fried something? Are there any poly fuses that might come back to life after a rest? Frustrating as I was making such good progress on my project!

I guess I expected the PWR led to be lit any time 5V was feeding the board, regardless of it's On/Off state. Certainly, in the dozen or so previous times I plugged the board in, just giving it power caused it to power on, so the idea of the POWER button actually being used to turn it on never occurred to me. If I could save face just a little here, I did actually press it a couple times before throwing in the towel, I just didn't consider holding it down for a few seconds.

Re: [beagleboard] Passwordless login to GDM for user other than root
Don: Thanks but no go. Below are the contents of the file /etc/gdm/custom.conf as found in the distribution Angstrom image: [daemon] TimedLoginEnable=true TimedLogin=root TimedLoginDelay=10 Obviously this is successful in having root login automatically as that is what happens! Changing root to my new user causes the login process to hang with the login form displayed but nothing further. Changing root to xuser, which also comes as part of the image, results in the same behaviour which is a hang. There has obviously been something done when the image was built to have root login. Hopefully one of the BBB folks will see this post and help out! Looking at top shows that gdmconf-2 is running constantly with about 9% CPU usage. Help!
