# About
|
|
This is a manual test application for the PIR motion sensor driver.
|
|
|
|
In order to build this application, you need to add the board to the
|
|
Makefile's `WHITELIST` first and define a pin mapping (see below).
|
|
|
|
|
|
# Usage
|
|
There are two ways to test this. You can either actively poll the sensor
|
|
state, or you can register a thread which receives messages for state
|
|
changes.
|
|
|
|
## Interrupt driven
|
|
Connect the sensor's "out" pin to a GPIO of your board that can be
|
|
configured to create interrupts.
|
|
Compile and flash this test application like:
|
|
|
|
CFLAGS="-DPIR_PARAM_GPIO=name_of_your_pin -DPIR_PARAM_ACTIVE_HIGH=if_gpio_pin_is_high_or_low_when_pir_is_active" make BOARD=your_board clean all-interrupt flash
|
|
|
|
Ideally, the above configuration passed via CFLAGS should be in "board.h"
|
|
|
|
The output should look like:
|
|
|
|
kernel_init(): jumping into first task...
|
|
|
|
PIR motion sensor test application
|
|
|
|
Initializing PIR sensor at GPIO_8... [OK]
|
|
|
|
Registering PIR handler thread... [OK]
|
|
PIR handler got a message: the movement has ceased.
|
|
PIR handler got a message: something started moving.
|
|
PIR handler got a message: the movement has ceased.
|
|
|
|
|
|
## Polling Mode
|
|
Connect the sensor's "out" pin to any GPIO pin of you board.
|
|
Compile and flash this test application like:
|
|
|
|
CFLAGS="-DPIR_PARAM_GPIO=name_of_your_pin -DPIR_PARAM_ACTIVE_HIGH=if_gpio_pin_is_high_or_low_when_pir_is_active" make BOARD=your_board make clean all-polling flash
|
|
|
|
Ideally, the above configuration passed via CFLAGS should be in "board.h"
|
|
|
|
The output should look like this:
|
|
|
|
kernel_init(): jumping into first task...
|
|
