I bought following screen http://www.buydisplay.com/default/7-inch-lcd-module-capacitive-touch-screen-panel-i2c-spi-serial. I have configured the screen for SPI and after a bit of struggle I managed to get the screen to work by using AdaFruits library for the RA8875 chip. Now I would like to access the SD card slot built in on the screens PCB, but I just can't get that to work! I use SPI for communicating with the SD card slot and has connected the MISO, MOSI and SCLK to it, the same as the screen uses, the screen has SS at pin 10 and SD card slot uses pin 4. As what I understand this is the way to hook up SPI devices. The screen does work in this configuration but not the sd card. I have double checked the wiring, I'm using a fully functional SD card, I have measured the voltage to the SD SD card slot but all these things are fine. So I wonder if you guys have any suggestions or experiences with similar stuff? Also is this the way to wire up SPI devices, and does the native arduino SD library support DUE?
Thanks in advance!
