IO Config Setting
When the correct AD value is selected and the Connect Status shows "Connect", it means the EVB has been
successfully connected. As shown in the green box in Figure 13, the GUI will identify and display the correct
firmware version, software version and chip part number.
As shown in the blue box in Figure 13, KEY0~KEY15 can be set as one of touch keys, Slider1, Slider2, Shield and
GPIO functions. The functions that can be set for each IO pin are mutually exclusive. AD pin can be set as
KEY15.
If the IO pin is selected as a touch key, it can be used as a button. IO pin can be set to GPIO (high) or GPIO (low).
GPIO (high) here means that the IO pin is set to output high level, and GPIO (low) means that the IO pin is set to
output low level.
Slider can choose Slider Bar (Open-end) or Slider Wheel (Close-end). Slider needs at least 6 IO pins. Users can
define IO pins according to the required functions.
Users should click Apply button located at bottom right corner to submit setting.
