Using the LCD_H-tree of owfs I should have Pins 0-2 for free use. For reading a button-state PIO.X should be 0. But when i do a
echo 1 > LCD_H/clear
echo test > LCD_H/screen
owfs changes the PIO-states to 1.
On the other hand when I do
echo 0 > PIO.0
there appear some strange characters on the display.
