    hi experts,

    i follow this this guideline(PiScreen Driver installation instruction) to setup my LCD, the IMG i use is 2015-05-05-raspbian-wheezy.

    when i type this command(fbi -noverbose -T 1 -a -d /dev/fb1 image-test.gif), there is nothing on LCD screen.
    root@raspberrypi:~# fbi -noverbose -T 1 -a -d /dev/fb1 image-test.gif

    Please comment out this line by placing a '#' in front;
    dtparam=spi=on

    Then reboot

    If that fails to work, download the image below. PiScreen should work on first boot.

    Hi Mark,

    Big thanks to you quick response:)
    I have not took my Pi to classroom, so i cannot verify your solution.

    And i have one question for your solution:
    For my understanding, piscreen connects RasPI with SPI interface, so, i think we should configure SPI as ON before we set piscreen as default monitor, what is your comments?

    If i remember, one or two months ago, i have modifed /etc/modules to add some fbtft device configuration information when i followed the guideline 'PiScreen Driver installation instruction', i guess that the guideline maybe updated, would you please send me the previous version of 'PiScreen Driver installation instruction' if possible? because i want to configure other TFT LCD(not piscreen but notro fbtft support) for my PI, i think it is the best guideline i have read but i cannot find it from your website.

    Thanks!

    The driver has been updated to use the functionality of device overlays, more information here;
    https://www.raspberrypi.org/documentation/configuration/device-tree.md

    If you would like to use the old method,
    Remove dtoverlay=piscreen,speed=8000000,rotate=90 from /boot/config.txt.
    Keep dtparam=spi=on to use the old method
    The add the below to /etc/modules

    flexfb width=320 height=480 regwidth=16 init=-1,0xb0,0x0,-1,0x11,-2,250,-1,0x3A,0x55,-1,0x36,0x28,-1,0xC2,0x44,-1,0xC5,0x00,0x00,0x0,0x0,-1,0xE0,0x0F,0x1F,0x1C,0x0C,0x0F,0x08,0x48,0x98,0x37,0x0A,0x13,0x04,0x11,0x0D,0x00,-1,0xE1,0x0F,0x32,0x2E,0x0B,0x0D,0x05,0x47,0x75,0x37,0x06,0x10,0x03,0x24,0x20,0x00,-1,0xE2,0x0F,0x32,0x2E,0x0B,0x0D,0x05,0x47,0x75,0x37,0x06,0x10,0x03,0x24,0x20,0x00,-1,0x11,-1,0X29,-3
    fbtft_device debug=3 rotate=90 name=flexfb speed=16000000 gpios=reset:25,dc:24,led:22

    The touchscreen is no longer supported in the old method

    Hi Mark,

    Thanks for your help!
    The old method works, i can startup the X on LCD.

    It's still failed when i try the new method, i will confirm my steps to you:
    1, download the newest IMG from RasPI website and write it to TF card, current the IMG is 2015-05-05-raspbian-wheezy.img;
    2, start PI, execute apt-get update and apt-get upgrade then reboot PI(because the IMG is the newest version, some times i ignore this step, and some times i execute command raspi-config and rpi-update before this step);
    3, add new line(dtoverlay=piscreen,speed=16000000,rotate=90) to file /boot/config.txt then reboot;
    4, try to perform a quick test as your guideline, but failed:(

    Below is the old method dmesg log:

    Mmmm... the above log looks like it loaded. And after step 3 above, steps should get the driver loaded. (A few other things need to be done to get X windows and the console on PiSCreen)

    Some questions;
    1)Is this the test you did?

    sudo apt-get install fbi
    wget https://ozzmaker.com/piscreen/image-test.gif
    sudo fbi -noverbose -T 1 -a -d /dev/fb1 image-test.gif

    2)Can you tell if the backlight has come on?
    3)Is the screen black or white?
    4)can you show me the output of sudo vcdbg log msg

    Everything looks fine in those logs.

    You shouldn't ever have a white screen. One list thing... can you please take a photo of the white screen and upload it to the forum.

    Hi Mark,

    Actually, I am not sure that the LCD with white screen, maybe i confuse the LCD backlight with white screen.

    Attach file is the running photo, the screen does not change from PI power on.

    Thanks.

    BRs,

    Hi Mark,

    I have not the receipt, because this is my friend's award from Makers' party.
    This is very strange, it's works well when i configure with old method; but when i change to new method, it does not work.
    Anyway, thanks for your help.

    BRs,
    Shannon
