I am using EVE to add a graphical touch interface to my coffee machine design. When I mount the display behind the protective glass, the touch is not always recognised correctly?

Many capacitive touch panels (CTP) have adjustable sensitivity. In this case, you can use our custom touch feature to configure this by writing to the registers of the CTP. This will help to ensure a good user experience with your touch interface. Check the datasheet for your CTP to find out which settings it supports. Custom touch is available on BT881, BT883, FT811, FT813, BT815, BT817 and BT817A. Find out more in our capacitive touch guide BRT_AN_090.
