In our new application note “HID compatible PC Keyboard” we explain to you how easy it can be to develop a capacitive keyboard around the PE5004 sensor signal conditioner IC. Due to its capability to address up to 100 sensor signals virtually simultaneously you can design a multi-functional touch keyboard with only a few components.
You will find the keyboard layout and schematics together with an example for a microcontroller board that will communicate the human interactions to the PC via USB-interface. The complete source is also available for download at our website.
Additionally we like to make you aware that we plan to release a new version of our popular EVA5004 capacitive sensing Evaluation Kit till the end of February.
We also like to mention that our PE5004 Capacitive Sensing IC has been nominated for Top111 products of the year 2010 (link) by the German trade magazine “Elektronik”.
