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).

/**

|
* \page sam3s_ppc SAM3S PIO Parallel Capture
|
|
*
|
|
* \section Purpose
|
|
*
|
|
* Interface for configuration the PIO Parallel Capture peripheral.
|
|
*
|
|
* \section Usage
|
|
*
|
|
* -# Configurate the interrupt for PIOA, can be done by PIO_InitializeInterrupts()
|
|
* -# Initialize the PIO Parallel Capture API by filing the SpioCaptureInit structur.
|
|
* 2 options:
|
|
* - alwaysSampling: for sample data with or without take in account ENABLE pins.
|
|
* - halfSampling: for sample all data or only one time out of two
|
|
* -# Call PIO_CaptureInit() for init and enable the PDC, init the PIO capture.
|
|
* -# Call PIO_CaptureEnable() for enable the PIO Parallel Capture.
|
|
* -# When an interrupt is received, the PIO_CaptureHandler() is call and the respective
|
|
* callback is launch.
|
|
* -# When the transfer is complete, the user need to disable interrupt with
|
|
* PIO_CaptureDisableIt(). Otherway, the PDC will send an interrupt.
|
|
* -# The data receive by the PIO Parallel Capture is inside the buffer passed in the
|
|
* PIO_CaptureInit().
