    Hi guys,
    I'm working on my first embedded project and would like to use your experience.
    I've got this LCD with a combined SD card reader from a friend
    without any datasheet or manual.

    As you can see in the picture, there is a pin for SD_CS but there are no pins to interface with the SD card.
    I've done lots of research for a datasheet of this screen with no success.

    What do you think ? is it unusable or is it suppose to work with the touch panel SPI interface pins ?

    Thanks a lot,

    Well, it says "Model YX32B". What did you find when you searched on that?

    These things can be hard enough to get working even if you do know exactly what it is. I used a Microelectronica board with the Microchip graphic libraries since the interface had the software driver; it only took me a solid week plus to find the error in their driver code.

    TP_SO, TP_SI and TP_SCK should work with SD_CS to rub the SD card, guessing both SPI devices share the interface.

    Bottom line: unless you find the data sheet for the chip on this board strongly consider re-purposing it as a drink coaster.
