PiTFT no Video but Calibrate works ?

Post by morwic »

Meh... I'm going to say it,

it does not work :(

Hello All,
I have the PiTFT installed on a Pi and when I go step by step with the install webpage on your site " with out errors" :), I run the calibrate tool I can see that the TFT sees me touching the screen, I see it on my computer via the calibrate tool.. So I think I have installed the unit right, but I get no video at all on startx, & the calibrate tool "step2" on the install guide ? any help would be great :)
Thank You

Double check the flex cable between the TFT and the PCB. It's easy to pull that slightly out of line when you put the PiTFT together, and almost impossible to see the difference.

If that doesn't work, post a photo of your solder joints and we'll take a look.

Running `sudo dpkg-reconfigure console-setup` should write the information to the correct files.

Same project butt I need some button help please the top part of the page

https://learn.adafruit.com/adafruit-pit ... -pi/extras

talks about turning on off the backlight with code. But can I have a backlight off on one button and backlight on with the next button, if so what are the GPIO numbers for the 3 other buttons ? and what would that code look like in the adafruit.conf file ?
Thank you

The power-down button is special: we created a kernel module that watches the GPIO in and starts a shutdown sequence if it sees a button press.

There's no equivalent kernel module for the backlight, so you'll need a script running in the background that watches the buttons you want to use, and sends the appropriate signals to gpio232. To get a general idea of using pushbuttons for signals, take a look at this tutorial: https://learn.adafruit.com/playing-soun ... spberry-pi

The GPIO pins exposed as buttons on the PiTFT are #18, #21, #22, and #23.
