WaveShare 7-inch user space driver

AndroidThings driver for old version of the WaveShare 7-inch HDMI LCD that did not use the standard HID protocol.

This driver was inspired by the work of derekhe https://github.com/derekhe/waveshare-7inch-touchscreen-driver

Usage

Add the following lines to the config.txt so the display is setup correctly

max_usb_current=1
hdmi_group=2
hdmi_mode=1
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0

After that simply start the service when starting your app

startService(new Intent(getApplicationContext(), TouchscreenDriverService.class))
