Andrew Reed / Mbed OS mbed-os-example-capsense-sw2-tft

This is a demonstration of using the tft display of the Cypress PSoC 6 WiFi-BT Pioneer kit. The demo displays the status of the capsense buttons, slider and user button on the tft display. Makes use of emwin, capsense and PinDetect libraries.

Dependencies:   PinDetect
