A Getting Started guide on compiling and executing "Arduino code" on embedded Linux boards.

Getting Started
There are 2 methods to run Arduino code on the BeagleBone Black.
- Native compilation
- Compilation using a cross compiler
Toolchain
BeagleBone Black
~$ wget http://www.angstrom-distribution.org/toolchains/angstrom-2011.03-x86_64-linux-armv7a-linux-gnueabi-toolchain.tar.bz2 ~$ sudo tar -C / -xjf angstrom-2011.03-x86_64-linux-armv7a-linux-gnueabi-toolchain.tar.bz2 ~$ export PATH=/usr/local/angstrom/arm/bin:$PATH ~$ export CROSS_COMPILE=arm-angstrom-linux-gnueabi-
Links to 64 and 32 bit versions of Angstrom toolchain.

Cloning
- Clone the repo from https://github.com/prpplague/Userspace-Arduino
git clone https://github.com/prpplague/Userspace-Arduino.git
Running a demo
Running Blink LED program:
cd Userspace-Arduino/arduino-makefile/examples/BlinkUserspace make
- 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
make upload
- 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)
- If you want to avoid a password prompt, you can set up the ssh keys for the Beaglebone Black:
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
Boards Supported
Beaglebone Black
Initial development is being done with the Beaglebone Black and the Bacon Cape
- if you have your Beaglebone Black loaded with a firmware image older that 07.11.2013, you will need copy the Bacon Cape dtbo file on to your beaglebone black
~# scp ~/Downloads/BB-BONE-BACONE-00A0.dtbo root@192.168.7.2:/lib/firmware/BB-BONE-BACONE-00A0.dtbo

- Initial support started
- Need Lure accessory board for testing
Raspberry Pi
- support planned
- will use RPi_Gertboard for initial development
