[beagleboard] Re: programming BBB - choice of language
This is a really interesting thread, I haven't learned so much so quickly in awhile! Hi Chilli I am also in a position where I'm developing a BBB with a touchscreen. I chose python. I hardly ever used python previous to this project and usually choose node.js or ruby which I know pretty deeply through years of web development experience. I chose python because * it has great support for the serial port which I needed fine control over (node-serialport failed, it was my first attempt, I was sad about this because I have to later refactor my python code in a tickless or event-driven style when I have time -- I would have got this for free if I had been able to use Node.js. Also with Node.js, if my project is a success, I can find an abundance of coders that can wield it, but same can be said for python) * it has a fine webserver built in, cherrypy, this is serving my HTML and Javascript for the kiosk * it has a fine websockets library, ws4py, which provides the connection between the python and the kiosk (which uses Chromium's HTML5 WebSocket) So far this working very well for me as my screen is doing normal things, nothing crazy to require OpenGL or SDL or things like that which are more foreign to me. My kiosk is using the following libraries: * Backbone.js (for its minimalism and modularity, although I tend not to use this anymore in normal web app development [I tend to write normal web apps in Meteor these days]) In your case you could easily do something like this and the protocol you develop on the websocket wire (or a superset therein) can be (re)used for non-local connections. The same HTML/JS can be reused (and extended) for those non-local connections. best regards, keyvan On Wednesday, March 11, 2015 at 7:01:23 AM UTC-7, Stephan Mulacz wrote: Somehow we came a bit of topic.

The TV knows there's something there (it disables inputs that are inactive, and it allows me to select the HDMI input to which the BeagleBone is connected) but says No Signal, whereas the monitor just says No Signal. I've tried both the preinstalled Angstrom Linux and the console version of Ubuntu 13.04 - no dice with either. I've got a proper micro-HDMI to HDMI cable arriving tomorrow, just in case there's something the BeagleBone Black doesn't like about the adapter I'm using (although I tested it on a Nokia 808 PureView, and it worked fine.) Anybody any ideas what might be preventing the BeagleBone Black from bringing up a display? I can see nothing in the kernel logs that sheds any light on the matter. It sees the virtual HDMI cape in Slot 6 and appears to load the firmware cape-boneblack-hdmi-00A0.dtbo fine. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] Re: BeagleBone Black - No HDMI Output
Hello Gerald Robert, Actually I am working with three BBB boards, two of them are ok with LCD display I am using. They all have preinstalled linux 3.8.13-bone70. I had checked the link you send me Robert. (I guess it is really exceptional case that BBBs displaying on 1080@60 lcd screen). On one BBB that I had a problem I reinstalled linux 3.8.13-bone41 accidentally, and after upgraded to bone70. Before intallation bone41 it did not even display anything on LCD, but after upgrade to bone70 at least it is displayin debian logo for 2-3 seconds. I am not sure whether they have same u-boot version. Is it ok if I update you tommorow? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] Re: programming BBB - choice of language
Hi William Although node-serialport did not work for me, in retrospect I can't blame the library. My application required control over the handshaking signals so I needed something capable of that. At the time, node-serialport did not have this feature but pyserial did. So I went with pyserial which caused everything else to be in python as well. I'm happy with the outcome though. best regards, keyvan On Sun, Mar 15, 2015 at 4:20 PM, William Hermans yyrk...@gmail.com wrote: Keyvan, Hey there.

Re: [beagleboard] Audio Cape with Beaglebone Black
That could be done while connecting BB with the computer? How can it be done when using BB alone as separate computer? The recorded audio needs to be stored,processed and played. So, how can it be done ?
