| :name: Renesas Low-voltage Detection Sample using Comparator |
| |
| Demonstrates monitoring and reacting to voltage levels. |
| |
| Overview |
| ******** |
| |
| This sample application shows how to use Comparator to monitor voltage levels |
| with Renesas Low-voltage Detection (LVD). |
| |
| Hardware Setup |
| ************** |
| |
| - Ensure that the monitored target pin is supplied with power. |
| |
| Building and Running |
| ******************** |
| |
| To build and flash the sample on a supported Renesas RX board: |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/boards/renesas/lvd |
| :board: rsk_rx130@512kb |
| :goals: build flash |
| :compact: |
| |
| The comparator configures trigger is rising edge. When the voltage on the monitored pin |
| crosses the threshold (Vref) - defined in the board's device tree, an interrupt is generated |
| and turns the LED on. |
