This way we can easily check with 'diff' for differences in our code and Atmel softpack. Also, this layout is more suitable for building various different firmware images (e.g. factory-test, dfu-loader, main application) for a variety of different boards (simtrace, owhw, qmod).

|
|
* \par Purpose
|
|
*
|
|
* Configuration and handling of interrupts on PIO status changes. The API
|
|
* provided here have several advantages over the traditional PIO interrupt
|
|
* configuration approach:
|
|
* - It is highly portable
|
|
* - It automatically demultiplexes interrupts when multiples pins have been
|
|
* configured on a single PIO controller
|
|
* - It allows a group of pins to share the same interrupt
|
|
*
|
|
* However, it also has several minor drawbacks that may prevent from using it
|
|
* in particular applications:
|
|
* - It enables the clocks of all PIO controllers
|
|
* - PIO controllers all share the same interrupt handler, which does the
|
|
* demultiplexing and can be slower than direct configuration
|
|
* - It reserves space for a fixed number of interrupts, which can be
|
|
* increased by modifying the appropriate constant in pio_it.c.
|
|
*
|
|
* \par Usage
|
|
*
|
|
* -# Initialize the PIO interrupt mechanism using PIO_InitializeInterrupts()
|
|
* with the desired priority (0 ... 7).
|
|
* -# Configure a status change interrupt on one or more pin(s) with
|
|
* PIO_ConfigureIt().
|
|
* -# Enable & disable interrupts on pins using PIO_EnableIt() and
|
|
* PIO_DisableIt().
