TJF, Thank you for your input. I do realize that my goals seem a bit ambiguous right now in reference to BBB, it is because I have a little difficulty understanding how it works. Having used the Arduino, I forget it is not as easy as to write the code in an Arduino software and simply burn it to the board that is connected to my PC using the USB cable.
My project is based on *Brain Computer Interface*: a headset will extract brain signals from a user, those signals shall be amplified, filtered, extracted and finally classified. These signals will then determine one out of the two movements to be performed on a robotic gripper having (at the moment) two fingers and a thumb. *Previously, this project was done using offline data. Ours require processing those signals in real time.* My senior who pursued this project using Arduino Uno told me when I asked about: *- what is the microcontroller used for*The arduino was connected to a SD card shield that used SPI communication to transfer data from the card to the controller. The card had a file with the EEG raw data on it in form of a text file. *- what was the input to your Arduino?* A text file with eeg raw data. *- what was the output?* A signal on a port that ran h-bridges. (h-bridge logic) (Yes, controlling a DC motor) -- *-> *In reference to *using LINUX*, in the long run, I would like to shift to having Linux on my Windows PC but in VM. So my question is - I can have any distro provided that I need to connect to my Debian based BBB? - Say I want to install Ubuntu, but *which version* is compatible with my BBB? - When my BBB arrives, do I need to upgrade it? (You mentioned the newly shipped BBB come with Debian and not Angstrom anymore; it is going to mention that, on the manual, yes?) *->* In reference to understanding some terms using a Linux machine to connect with a BBB - What is the substitute of an Arduino software where one writes code in c++ when using BBB? - How the code is burnt on the board? (i mean in the Arduino software, you would write the code and hit the button UPLOAD) - The connection you use is SSH? - You use your PC to write the code, and then transfer it to your BBB using SSH? (I read your answer about hosting the source files on the BBB. But I can't fully understand it so I asked the above questions. It means you are using your BBB as stand alone machine. Writing your source code on it. Then transferring it to you PC using the LAN connection? How does SSH come in?) Thank you for your time and detailed response. They are a huge huge help.
