To read out the state of switches, I configure GPIOs with IMODE-HIGH (\ input, pull up) (Forth-library), with an external pull up resistance of 10 k in serial with the switch. But, is the resistance needed, or is it already provided internally in this mode?
Does anyone know?
One could guess that the pull-up resistance is included, because there are different configuration modes for pull-up and pull-down. A test confirmed this assumption, it works, just a switch between GPIO and GND.
