Enchanted Objects - Enchanted Clock #2

dwinhold

Today was the arrival of the Arduino Yun, thank you very much to all our sponsors.

 

So Chrystal and I have been busy cutting out a clock and programming the Arduino and LED cape. In order for the clock to keep time we are going to have a sensor detect the minute hand gear for correct 1 hour per revolution. If the hands are out more then 2 minutes it will be corrected by the arduino connected to the servo. We also connected 3 ultrasound sensors to check for movement in the room. If the distance to the couch without anyone on it (say 12 ft) is sensing a distance of 10 ft 8 in, the arduino will consider that it is occupied. if that distance doesn't change more then 1" in 10 minutes it will figure the occupant is sleeping and turn down the lights. We also are using one to check the height of the person standing in front of the clock and call them by name. Chrystal thought this would be an enchantin idea to add. There is a lot more to update with photos which will come tomorrow.

 

A quick question to everyone, is the SAMA5D4 xplained not very well explained? I can't find anything that isn't a demo. I have been going crazy to come up with a useable OS for it, I am even trying to create my own, but time is the problem. Is there any non-demo OS available? Hacking the files got nowhere, I do require direction with this. I am not new to development boards, but this is got me baffelled. I have created a Beowulf cluster from RPi's, changed the RPi to run the gpio's from Scratch language for my kids. Any advice on non-demo software?

 

Thank you all,

  • A quick question to everyone, is the SAMA5D4 xplained not very well explained? I can't find anything that isn't a demo. I have been going crazy to come up with a useable OS for it, I am even trying to create my own, but time is the problem. Is there any non-demo OS available? Hacking the files got nowhere, I do require direction with this. I am not new to development boards, but this is got me baffelled. I have created a Beowulf cluster from RPi's, changed the RPi to run the gpio's from Scratch language for my kids. Any advice on non-demo software?

    I'm struggling with that one too. I am as far now as what is showing in his SAMA5D4 Xplained Ultra - Tips and Tricks #1 - Getting Displays up and Running

    I can replicate his actions to load a binary to the board.

     

    I've spent way more time that I can afford in getting an example from th AT19 site compiled.

     

    I have downloaded sama5d4x_xplained_softpack_1.2_for_CodeSourcery_201410 from SAMA5D4 Software Package and installed loads of Tool Chains, no luck:

    Atmel Studio 6.2. As yet unable to get a project up and running for this board.

     

    • From command line with make:
    • From ARM DS-5
    • From a plain Eclipse.

     

    All 3 fail on the first directory creation: 

    sama5d4x_Xplained.mk:187: recipe for target 'debug_sama5d4x_Xplained' failed
process_begin: CreateProcess(NULL, mkdir debug_sama5d4x_Xplained, ...) failed.
make (e=2): The system cannot find the file specified.

     

    I've been digging in the make files and googled the error till death, no resolution yet.

    I have tried exerything you have as well, what I also don't understand is that everything downloadable is a "Demo" version. I don't want demos, I want an operational OS to work from. I've downloaded the Yocto Project to try to create my own, but don't have this kind of tme. I may try to create a ARM Linux OS from scratch and see if I brick the board trying to load it. If all else fails I may have to use a RPi or Beaglebone for this project, it would be a shame to have to do this.

    Yes, I am considering the same options. Even the Yun should work but is planed for a surpise (if I have time left).

    I have an additional issue of not beeing able to use the debug USB port for serial console. Fortunately I have UART to USB converter which works fine.
