Userspace Arduino

 Development Blogs for the Userspace Arduino project:
 * Primary Blog for work on the project
 * Parav Nagarsheth's Blog about his work on the project
 * Anuj Deshpande's Blog about his work on the project

This page documents research on creating a userspace executable using the wiring and Processing language used with Arduino.

Beaglebone Black
The examples have been tested to work on production images later than 2013.06.20. You will need a 4 GB (or greater) microSD card for flashing the Beaglebone Black, a process which may take well over 45 minutes. It is documented on the CircuitCo wiki. If you are unsure which image is currently loaded on the Beaglebone Black, check it at http://www.crashcourse.ca/wiki/index.php/Examining_your_BBB_install_version.

Cloning
git clone https://github.com/prpplague/Userspace-Arduino.git
 * Clone the repo from https://github.com/prpplague/Userspace-Arduino

Running a demo
Running Blink LED program: cd Userspace-Arduino/arduino-makefile/examples/BlinkUserspace make make upload
 * A binary BlinkUserspace.elf should be created in a directory build-userspace
 * send-exec is an upload and execute script, which is integrated with the Arduino-Userspace repository. It uses the scp protocol to copy binaries to the Beaglebone Black over USB/ethernet and execute it. You can find it in the utility folder.
 * To use it, simply do
 * You will now see USR LED 1 blinking at one second intervals. Press Ctrl-C to break from the loop.
 * Check out some of the examples in /path/to/Userscape-Arduino/Arduino-Makefile/examples.

Setup SSH keys (optional)
cd ~/.ssh ssh-keygen -t dsa #set a password or you can leave it blank ssh-copy-id -i ~/.ssh/id_dsa.pub root@$192.168.7.2 # replace id_dsa.pub by your public key file if some other name is given ssh root@192.168.7.2 # login and enter password once Here after, you won't be prompted for a password from this machine
 * If you want to avoid a password prompt, you can set up the ssh keys for the Beaglebone Black:

Beaglebone Black
Initial development is being done with the Beaglebone Black and the Bacon Cape ~# scp ~/Downloads/BB-BONE-BACONE-00A0.dtbo root@192.168.7.2:/lib/firmware/BB-BONE-BACONE-00A0.dtbo
 * if you have your Beaglebone Black loaded with a firmware image older that 07.11.2013, you will need copy the [[media:BB-BONE-BACONE-00A0.dtbo|Bacon Cape dtbo file]] on to your beaglebone black

MinnowBoard

 * Initial support started
 * Need Lure accessory board for testing

Raspberry Pi

 * support planned
 * will use RPi_Gertboard for initial development
