History

Lucas Jenss 426170b064 Improve naming of thread stacksize/priority constants As discussed in #2725, this commit renames a number of stacksize constants to better convey their intended usage. In addition, constants for thread priority are given a `THREAD_` prefix. Changes are: * KERNEL_CONF_STACKSIZE_PRINTF renamed to THREAD_EXTRA_STACKSIZE_PRINTF * KERNEL_CONF_STACKSIZE_DEFAULT renamed to THREAD_STACKSIZE_DEFAULT * KERNEL_CONF_STACKSIZE_IDLE renamed to THREAD_STACKSIZE_IDLE * KERNEL_CONF_STACKSIZE_MAIN renamed to THREAD_STACKSIZE_MAIN * Move thread stacksizes from kernel.h to thread.h, since the prefix changed * PRIORITY_MIN renamed to THREAD_PRIORITY_MIN * PRIORITY_IDLE renamed to THREAD_PRIORITY_IDLE * PRIORITY_MAIN renamed to THREAD_PRIORITY_MAIN * Move thread priorities from kernel.h to thread.h since the prefix has changed * MINIMUM_STACK_SIZE renamed to THREAD_STACKSIZE_MINIMUM for consistency		2015-05-21 00:14:23 +02:00

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:

export BOARD=your_board
export PIR_GPIO=name_of_your_pin
make clean
make all-interrupt
make flash

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:

export BOARD=your_board
export PIR_GPIO=name_of_your_pin
make clean
make all-polling
make flash

The output should look like this:

kernel_init(): jumping into first task...
PIR motion sensor test application

Initializing PIR sensor at GPIO_10... [OK]
