|
||||
* \section Purpose
|
||||
*
|
||||
* This file provides a basic API for PIO configuration and usage of
|
||||
* user-controlled pins. Please refer to the board.h file for a list of
|
||||
* available pin definitions.
|
||||
*
|
||||
* \section Usage
|
||||
*
|
||||
* -# Define a constant pin description array such as the following one, using
|
||||
* the existing definitions provided by the board.h file if possible:
|
||||
* \code
|
||||
* const Pin pPins[] = {PIN_USART0_TXD, PIN_USART0_RXD};
|
||||
* \endcode
|
||||
* Alternatively, it is possible to add new pins by provided the full Pin
|
||||
* structure:
|
||||
* \code
|
||||
* // Pin instance to configure PA10 & PA11 as inputs with the internal
|
||||
* // pull-up enabled.
|
||||
* const Pin pPins = {
|
||||
* (1 << 10) | (1 << 11),
|
||||
* REG_PIOA,
|
||||
* ID_PIOA,
|
||||
* PIO_INPUT,
|
||||
* PIO_PULLUP
|
||||
* };
|
||||
* \endcode
|
||||
* -# Configure a pin array by calling PIO_Configure() with a pointer to the
|
||||
* array and its size (which is computed using the PIO_LISTSIZE macro).
|
||||
* -# Change and get the value of a user-controlled pin using the PIO_Set,
|
||||
* PIO_Clear and PIO_Get methods.
|
||||
* -# Get the level being currently output by a user-controlled pin configured
|
||||
* as an output using PIO_GetOutputDataStatus().
