Just got my second 4DPI-35. Ordered from RS-online. This is my third TFT from 4D systems. All ordered from RS. All in great quality. Again, don’t bother order from Taobao, they will just ship you a malfunction item.
Installation is too simple, just download the deb file, use dpkg to install it. That’s all.
Here is the installation procedures for Raspberry Pi 2b.
$ sudo su
# wget http://www.4dsystems.com.au/downloads/4DPi/kernel4dpi_1.3-3_pi2.deb
# dpkg -i ./kernel4dpi_1.3-3_pi2.deb
After reboot, login again.
I pick up the development again with the screen, and the above no longer works… I go back to the installation as described in the official datasheet.
