I am trying to use the RS232 to control a circuit board. It would have to simultaneously output SerialClock, DataIn, and Chip Select signals, while also receiving DataOut signals; therefore 4 signals total. Does anyone know if it this is possible?

I am trying to splice 4 wires out of the RS232 serial cable (the 9-pin type) and wire them to a circuit board. The 4 wires would control 4 signals: DataIn, DataOut, SerialClock, and ChipSelect. The serial clock would synchronize the DataIn and the ChipSelect is asynchronous. DataOut must coincide with SerialClock also; therefore there are 3 signals that must be able to switch concurrently. All the handshaking enabled by RS232 is thus unnecessary in my opinion. Does anyone know of how this can be done?

  • Does anyone know how or if even possible to block stations and limit content on iTunes Radio?

    Does anyone know how or if even possible to block stations and limit content on iTunes Radio?  I have younger children listening to inappropriate music.  I have the iPad locked down but that doesn't seem to help.

    Thank you for your response! I just don't want to spend more time on beautifying the libsyn page via hours of dumpster diving for code hence reaching out on here about iWeb (even if it's sadly been put out to pasture). This was the response that I got from Libsyn about this:
    Hello,
    Thanks for contacting us. Just to clarify, our system's blog page templates are basic 'starting points' -- we're working now to improve our basic blog page templates to make more options available to Libsyn users.
    You might be able to use your Libsyn show's RSS feed to generate content on an iWeb page. You could do a Google search for 'convert RSS to HTML' to learn more. Here's a link for more info about generating HTML content from an RSS feed source:
    http://www.blogtips.org/free-rss-tools/
    We appreciate your feedback and suggestions. Please let us know if you have any questions. 
    Any thoughts? Btw, if it possible to 'view source code' for an iWeb page that's created or to take html code and plaster it into an iWeb page? If that's possible then I might be able to use iWeb for Libsyn.

  • The user acct my apple was connected to no longer works (corrupt).  My Apple TV is still synced to that account and all of my recent purchases are going to that username.  Does anyone know how to get all of the purchased items back and to the new user?

    The user profile my appleTV was synced on my computer to no longer works (corrupt).  My Apple TV is still synced to that profile and all of my recent purchases are going to that username.  Does anyone know how to get all of the purchased items back and to the new user (same computer)?  I created a new user on my computer and moved the itunes folder to the desktop but never changed the path to which the apple synced to.  Now I can only see old items I purchased before the user profile went bad.  PLease help!

    Welcome to the Apple Community.
    Changing the library the Apple TV is synced with will delete all synced content from the Apple TV, but it won't delete purchased content.
    You should be able to change the library, resync any content you want and transfer your purchases back to the new library.

    Does anyone know what fonts this is?
    Thanks so much!

    Can anyone please tell me what font this is below? I'm not sure if this is what it looked like before I started manipulating it, but I definately forgot to write down the font before creating outlines in Illustrator!
    If someone knows, it would save my life!!!
    Thanks ahead of time!!

    I don't know how to turn off a kitten (I would probably get the Nobel prize if I did!) but Pierre is correct, although his target is wrong:
    System Preferences/Universal Access/Seeing - turn off VoiceOver.

    Audition 3 and earlier versions were never available for Mac systems.  OS X support was introduced in CS 5.5 (version 4.0)??

    In regards to the iPhone being officially unlocked by ATT thru Apple?
    No.
    A problem arises when installing an iOS update on an iPhone that was hacked to be unlocked.

  • Every so often when using safari my bookmarks disappear and then later the list shows up again.  Does anyone know what causes this and how to fix it?

    Every once in awhile while using safari my bookmarks list disappears.  Later it just shows up again.  Anyone know what causes this and how to fix it?

    I have had exactly the same problem now with two mini iPads.  Everything was tried; 1) restarting; 2) restoring factory settings etc.  NONE worked.  Eventually Apple agreed to replace it.  I have had the replacement now for two to three months and exactly the same thing is happening again. So off to Apple tomorrow to get another replacement.
    I am quite a heavy user of the iPad so wonder if this is something to do with the fault.
    It is so frustrating as sometimes reset works, and then after 10/20/30/40 minutes (you pick) it goes unstable again.

  • My early 2011 MBP 17 started showing a thin vertical red line one inch from the left edge of the screen. Does anyone know what causes this problem?

    Does anyone know what causes a thin vertical red line on the display?

    There is a problem with the display or the connection to the display.  Take it to an Apple store genius bar for a definitive diagnosis.  The diagnosis will be free, any repairs will not be free.
    Ciao.

    Does anyone know which font the word Compton is written in?

    A good site to help you identify fonts is:  www.whatthefont.com
    You'll have to cut the font you want it to check out so that it's in an image by itself.

    Hi could anyone help me out? my iphone 3gs keeps restarting itself every two minutes which i think is some kind of software issue,now there are a number of things i have done starting with putting in a new battery.when i charge the phone it resets itself every two minutes or so and the battery indicator stays at 4% so i decided to restore the phone on itunes (which is the latest edition) and when i connect my phone which i have put into recovery mode using the buttons, i get an error message saying :- the iphone software update server could not be contacted.a duplicate file name was specified. i have tried re-installing i tunes and that doesn't solve the issue and i have trawled through the program files to see if i could spot the duplicate but without success ,has anyone had the same issue and resolved it?

    An iPhone 3G cannot be updated beyond iOS 4.2.1...that's the end of the line for your phone.

  • I have an Intel based iMac that has just developed two small spots on the screen. One 1/8" circle at bottom and a tiny circle at top.  The fading on and off light isn't working anymore either.  Does anyone know anything about this?

    I have an Intel based iMac that has just developed two small spots on the screen - they look light brighter spots on the screen. One 1/8" circle at bottom right and a tiny circle at top right.  The fading on and off light on area surrounding the screen isn't working anymore either.  Has anyone else had similar problems?  Any solutions?  Thanks!

    One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
    PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
    Reboot, test again.
    If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
    Check the System Preferences>Other Row, for 3rd party Pref Panes.
    Also look in these if they exist, some are invisible...

  • Does anyone know what app this is?

    Hi guys. Just got a new iPhone 4 and I'm furiously looking for a particular application that I've seen a couple of people use to edit their photos within iPhone. It adds borders to photos and also edits their coloring. It's like a very mini Photoshop. I can't, for the LIFE of me, figure out which app it is. If anyone knows, could you please give me a heads up?
    Here's a link to one of the photos:

    I think you might want to look for a vintage photo editor. I saw one in the app store but I cant remember the name
