Odroid W with docking board and 2.2inch 320x240 QVGA color TFT LCD assembled #374

Closed perrycannon closed 7 years ago

perrycannon commented 8 years ago

I have an Hardkernel Odroid W connected a Odroid W docking board with a 2.2inch 320x240 QVGA color TFT LCD assembled attached.

I have followed the steps in the wiki to get the tft lcd to work. I am using Jessie debain updated. I have been unsuccessful. The tft lcd display will not work. Please help me.

Thank you Perry

The easiest way is to open a ssh terminal from your main computer. If you are on windows, download, by example, kitty (www.9bis.net/kitty/?page=Download). Type your raspberry IP Adress, port 22 and let's go to login.

From now, you will access your raspberry from your main PC, allowing you to directly copy/paste stuff with a simple right click. Note: maybe you should try your lcd on wheezy ?

Ok, as we don't see any fbtft, fbtftdevice or fb* stuff, it seems the setup procedure failed quite early. Let's assume we will do new attempts on fresh raspbian image. If you don't mind working on a non-updated wheezy, this guide is still looking relevant : http://odroid.com/dokuwiki/doku.php?id=en:odroidwtftlcd

In other case, take your jessie image : sudo rpi-update sudo apt-get update sudo apt-get upgrade Write "dtparam=spi=on" in /boot/config.txt ,reboot and try the : _sudo modprobe fbtftdevice name=adafruit22a con2fbmap 1 1 If you see something, that's fine, you can follow the "making it permanent section", in other cases, please paste here the last dmesg lines. There are some variation around the adafruit 2.2" drivers, "_sudo modprobe fbtftdevice name=adafruit22" may also be tried. Note that one of the old adafruit 2,2" is no more supported, hope you didn't get this one on your board !

Thank you for your help. The steps you provided worked. I used the latest NOOBS, then updated.

Now I need to learn how to rotate, and get the GUI on the tft. I was able to use the CLI on the tft, startx sent the GUI to the HDMI display.

Thank you for your help. Perry

Rotation should not be hard to achieve, as it's an option when loading fbtft_device. I assume the default rotation is 270°, dmesg may confirm it. In that case, try : sudo modprobe fbtft_device name=adafruit22a rotate=90

For displaying X, you may change /usr/share/X11/xorg.conf.d/99-fbturbo.conf and change "Option fbdev /dev/fb0" to "Option fbdev /dev/fb1".
