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...
PIR motion sensor test application
Initializing PIR sensor at GPIO_10... [OK]
Printing sensor state every second.
