+"""Demo on how to read and write digital IOs.
+
+In order for the output to work, the following configuration has to be changed in the ioconfig_tmc9660-3ph-eval.toml file:
+```toml
+[gpio18]
+type          = "output"    # "input", "output", "analog" (optional) (analog only supported on GPIO 2-5)
+output_value  = true        # false, true (optional)
+```
+
+On Windows the config upload and app start can be done with:
+    python ubltools_1.0.1/ubl_evalsystem_wrapper.py <COM-PORT> write config ubltools_1.0.1/ioconfig_tmc9660-3ph-eval.toml
+    python ubltools_1.0.1/ubl_evalsystem_wrapper.py <COM-PORT> start
+Where <COM-PORT> needs to be replaced by the COM port of the Landungsbruecke.
+
+Important: first connect USB and then power the TMC9660-3PH-EVAL.
