    Hi,

    I am quite a noob with electronics… I have tried connecting the ribbon based on the orientation shown however when I switch it on nothing boots up.

    am I doing it wrong?

    I have already attached my micro usb to the raspberry pi as well.

    Have you tried turning on the backlight? When I first started mine I thought it wasn’t working but was fine once the backlight was on

    And, have you installed the drivers? Without the drivers, PiScreen will remain off.

    Hi John,
    Forgive the igorance, do you have a picture of the backlight? There is an LED that is on. Not sure if that is the light you are refering to.

    Hi Mark,
    Where can the drivers be found? Sorry, I’m really not very technical. Would definitely like to bulk up my skills in this area.

    Thank you both for your patience and guidance

    It looks like you have PiScreen connected correctly.

    On one side of PiScreen, there is a on/off switch that turns the backlight on or off. I see that in your photo that it is ‘on’.

    I would say the problem is that you need to install drivers.
    If you follow the links below, they will definitely help you learn how it all works.

    Driver install Instructions here;

    Once you get the drivers installed, you should do these also;

    Enable Console on PiScreen

    Enable X windows on PiScreen

    Hi Guys,

    I seem to be having the same issue, I have installed the drivers and gone through the process of enabling the console on the screen but I am not seeing anything. I imagine the back-light functions regardless of the drivers? I’m not getting anything there with the switch in the on position.
    I don’t have a ton of time to investigate right now but if anyone else has this issue and finds a solution I’d love to know.

    Cheers

    Do you see the backlight on at all?
    The backlight will not come on if there are no drivers installed.

    Can you please show me the output of dmesg

    Hi Mark,

    I worked it out, I had LIRC running on the same pins used to drive the PiScreen. I just disabled it, rebooted and bam, the console is now visible and the backlight is on. Thanks for your help. It runs great!

    Cheers
    Ryan
