# How to connect a 4D display to a beaglebone black?

I am fairly new to all this so sorry if this question is rather trivial.

I have a 4D Picasso Display (28PTU-Pi) and I want to connect it to my Beaglebone board. So plugged the usb cable into the board and the splash screen came up. But how do I connect it so that I can actually run programs on it like the tutorial?

On the homepage I could only find this, but that's for a Raspberry Pi and not Beaglebone.

• I have successfully connected a 4DCAPE-43 to beaglebone black. From a time an effort standpoint this might be cheaper. But if you looking for hobby project (or real project for a customer), then this can be done. You need to weed through the 4D Picasso Display data sheet and map the I/O to BBB. Then you will have to make the necessary changes to BBB firmware – Mahendra Gunawardena Oct 28 '15 at 11:02

I copied all files onto the BBB then compiled the library, linked the libraries with the calculator.c program, changed the USB port to from ttyAMA0 to ttyUSB0 (in calculator.c) which is default I think for the BBB. and then run it and it worked.
