I'm quite new with Arduino, but i have a project that requires to play some kind of videos on a LCD (TFT) display, using some sensors and motors, and doing some music...
Since Arduino's CPU is too limited for doing all this stuff at once, my idea was to play videos and music on a Rasbperry PI, and letting Arduino doing some work with motors and sensors.
Apparently it's possible to connect a cheap LCD display to an Rasbperry PI using the serial bus according to this page : http://www.whence.com/rpi/
And on the same time I will have my Arduino and Rasbperry PI communicating through the serial bus (Arduino saying to Raspberry : "display video #1" for example).
But is there any risk of conflict between the LCD display slave and Arduino slave ? Is there a specific configuration to set up ? If I listen on serial information on Rasbperry PI (using python serial library), will I also read information about the LCD display that don't make sense for me ?
Sorry I don't have a solid background on Electronics, I'm just trying to know if my project is viable.
Thanks for your help
