I am interested in using a Pi as the basis of a simple music player - iPod style. The device will probably be permanently mounted inside my boat (tethered to the audio in of a car stereo).
I am not (yet!) familiar with many of the the hardware and software issues involved (which is the main reason I want to do this; as it will make a great learning project for me), so I wondered if anyone could give me some tips.
Ideally the device would consist of the Pi and a 4" (or thereabouts) touchscreen.
However, in my touchscreen researches I keep hitting a brick wall: I can't work out how the touchscreen should be interfaced to the Pi.
Presumably the display itself would connect to either the HDMI or the RCA connector, though none of the screens I've come across mention this. But how would the touch sensor connect? All the ones I've seen seem to have ribbon connectors - mostly for both the display and the touch sensor.
Resistive touchscreen overlays seem to normally have four wires - but where should these four wires be connected????
, for example, seems to have a 40-pin parallel connector... I can't see any way that could be connected to the Pi; could it?
If anyone could give me any tips that would be fantastic.
Equally, if anyone can point me to a source for a reasonably-priced touchscreen in the 3.5" to 5" range, I'd be very grateful, as I've been having trouble finding them. Ideally capacitive would be nice, but I don't know what pricing would be like. Resistive isn't a dealbreaker.
Thanks in advance!
