I'm using a GUI program Ham Clock from http://www.clearskyinstitute.com/ham/HamClock/.
The graphics are ok and they use 800x480. However when I touch the screen, the pointer is not at the touch point.
Tried to set the following in /boot/config.txt but make no difference.
Framebuffer also set to 800 x 480
Code: Select all
dtoverlay=rpi-ft5406, touchscreen-size-x=800, touchscreen-size-y=480
Any ideas please?
