This example shows how to configure the Analog-to-Digital Converter (ADC) to trigger a conversion on a specific event. The Timer/Counter type A (TCA) overflow is used to trigger the ADC sample accumulation and ADC result is transmitted through USART.

Control LED array using a force sensitive resistor on an AVR64DD32.

In the example application, the ADC result will be sent to an android/iOS app over Bluetooth communication using the RN4870 Click board. The ADC result will also be sent to a serial terminal and a 4x4 RGB Click board is used to illuminate different LEDs corresponding to the applied force on the force sensor on the Force Click board
