| :name: PAJ7620 Gesture Sensor |
| :relevant-api: sensor_interface |
| |
| Get hand gesture data from PAJ7620 sensor. |
| |
| Overview |
| ******** |
| |
| This sample application gets the output of a gesture sensor (PAJ7620) using either polling or |
| triggers, and outputs the corresponding gesture to the console, each time one is detected. |
| |
| Requirements |
| ************ |
| |
| To use this sample, the following hardware is required: |
| |
| * A board with I2C support (and GPIO to detect external interrupts in trigger mode) |
| * PAJ7620 sensor |
| |
| Building and Running |
| ******************** |
| |
| This sample outputs data to the console. It requires a PAJ7620 sensor. |
| |
| Polling Mode |
| ============ |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/sensor/paj7620_gesture |
| :board: nucleo_f334r8 |
| :goals: build |
| :compact: |
| |
| Trigger Mode |
| ============ |
| |
| In trigger mode, the sample application uses a GPIO to detect external interrupts, therefore GPIO |
| support must be enabled. Just like every sensor supporting trigger mode, it is possible to choose |
| between using a global thread (``CONFIG_PAJ7620_TRIGGER_GLOBAL_THREAD``) or a dedicated thread |
| (``CONFIG_PAJ7620_TRIGGER_OWN_THREAD``) for the interrupt handling. |
