Silicon Labs / Mbed 2 deprecated Segment-Touch-Demo

Using the cap slider and segment LCD on LG/WG/GG.

Dependencies:   EFM32_CapSenseSlider EFM32_SegmentLCD mbed

Demo program showing the capacitive slider and segment LCD functionality of the Leopard, Wonder and Giant Gecko Starter Kits.

Information

All examples in this repo are considered EXPERIMENTAL QUALITY, meaning this code has been created as one-off proof-of-concept and is suitable as a demonstration for experimental purposes only. This code will not be regularly maintained by Silicon Labs and there is no guarantee that these projects will work across all environments, SDK versions and hardware.
