Only the official RPF 7" screen can be used in the RPi DISPLAY (DSI) port.akashmittal wrote:I want to interface a 2.4 inch capacitive LCD touch screen with the Raspberry Pi using DSI connection, just like the 7 inch LCD (https://www.raspberrypi.org/products/ra ... h-display/). Since only 7 inch LCD is available for raspberry pi I was planning to use a standalone LCD (https://www.alibaba.com/product-detail/ ... 0.html?s=p) with the Raspberry pi. So is it somehow possible for me to make this work? Or, can I use the adapter board which is available with the 7 inch LCD, to work with the 2.4 inch display?
Thank you for your response.supra wrote:Here is link for adapter board. Scroll down to bottom

Thank you for yor response!CarlRJ wrote:As klrick said, the ONLY display that will plug into the DSI connector on the Pi (and work) is the Official 7" touchscreen. This is because such a display needs extensive support in the GPU, and that's the only one they've done the setup work for. Other displays need to connect via HDMI, composite (yuck), or SPI. Both Asafruit (with their PiTFT/PiTFT+ line) and Waveshare have displays in the 2.2"-3.5" range that mount on top of the Pi and connect via SPI. This requires some driver support, but the drivers for some of the displays are built in to Raspbian now. There are others out there too, but Adafruit and Waveshare are a good place to start looking.
None that I know of. It might be worth checking in the "Interfacing (DSI, CSI, I2C, etc.)" subforum to see if there's any recent developments.akashmittal wrote:So there is no way yet to configure any other screen using the DSI connectors?
Aside from that being unlikely to work, the only way to get that adapter board is to buy one of the Official 7" Displays.akashmittal wrote:What if i use the same adapter board as provided with the 7 inch display, just replacing the lcd with any other?
I've not seen nor heard of that one before, interesting.akashmittal wrote:Actually i was planning to build gui using embedded wizard software http://www.embedded-wizard.de/raspberry-pi.html.
I'm using PyGame on Adafruit's PiTFT 2.8" Capacitive Touchscreen displays (though there's currently some serious voodoo needed to get the touchscreen input working), and Kivy on the Official 7" touchscreen display. Those both seem to be the popular choices (at least for working in Python; I believe some also use Qt and other frameworks). They're also free, where Embedded Wizard looks to cost many thousands of Euros, if I'm reading right.akashmittal wrote:So if that can't be done then what other best alternatives ar there for building good gui on raspberry pi?
