Each of the Lumissil’s sensor products comes with a PC GUI for calibration and configuration. No firmware programing is required – simply calibrate the device to work with the specific capacitive touch electrodes and then save to a file or to the connected device flash memory. As an example of that, the IS31SE5117 evaluation board includes a main board with three touch keys, a slider daughter board and a wheel daughter board. The EzISP interface device provides for all devices USB to I²C interface to host where the GUI runs. It is used for calibration and configuration and possible device flash memory programing. Product GUI is available to install on a PC. Same GUI is to be used for both evaluation board and the target product. In the IO Config folder, first connect to the board by selecting the pre-set address option. Then each IO can be configured as a touch key, an open or close-end slider, shield driver or a GPIO. Also, this folder allow to export or import a complete calibration to the host or write it to the flash memory of the connected target device. Next, the key variations folder enables monitoring counts and setting individual threshold per key, as well as defining global gain and noise threshold. Setting-1 folder enables additional setup features such as Sleep mode setup, multi-key touch and Max touch duration. Setting-2 folder allows additional setups for noise filtering, key operation functionality and baseline processes. Setting-TK3 folder is for Signa-Delta touch parameters calibration and noise filtering parameters. Use the continuous analog graph folder representation of all active Cap-touch keys, to provide a sense of system operation condition. The Slider folder enables configuring and monitoring sliders operations – open or close loop, set keys for sliders, monitor slide direction and keys continued count levels. The Output Setting folder enables simple and flexible configuration touch keys to activate GPIO output operation without any need for programing. A configuration table can define specific Key inverting or toggling of a specific GPIO output. This enables quickly configuring the device to control operation of output functions such as Light elements, motors or other devices. In this specific evaluation board, three GPIOs are connected to three LEDs to demonstrate this functionality. The I²C communication folder enables users to manually issue commands and collect data from the device. This allows evaluating host controller operation commands and data collection from the IS31SE5117 device.
