05/05/2016 - 0.8.1
------------------
- Fixed some configure bugs relating to installing board files
04/05/2016 - 0.8
----------------
- Automatic board probing support via config file
- Python GPIO and I2C bindings
- test_configure.sh test script to catch configure regressions
- Special Thanks to Andy Doan <andy.doan@linaro.org>
09/12/2015 - 0.7.1
------------------
- Fixed compilation with musl
- Remove inline keywords as they dont play nice with GCC 5.2
- Misc cleanups from static analysis
05/11/2015 - 0.7
----------------
- Add named GPIO board support
- Fixed autoconf syntax error
- Special Thanks to Andy Doan <andy.doan@linaro.org>
02/07/2015 - 0.6.5
----------------
- Fix bug in GPIO interrupt polling
14/06/2015 - 0.6.4
----------------
- Fix autotools warnings
- Enable silent build
- Add packageconfig support
- Special Thanks to Yegor Yefremov <yegorslists@googlemail.com>
22/08/2014 - 0.6.3
----------------
- Initialise GPIO function pointer to NULL
- Style fixes
- Small scope optimisations
- Juggling of include files to more relevant places
- Special Thanks to Yegor Yefremov <yegorslists@googlemail.com>
16/06/2014 - 0.6.2
----------------
- Moved some required headers to include files
- Fix memory leak in GPIO lib error path
- Fix wrong SPI brackets in libsoc_spi_read which caused
function to return FAILURE regardless
- Special Thanks to Yegor Yefremov <yegorslists@googlemail.com>
22/05/2014 - 0.6.1
--------------
- Add support for BOTH edge interrupts
- Add include guards
- Add C++ ifdef support
- Include sysfs gpio bug fix for OMAP platforms
02/02/2014 - 0.6
------------
- PWM sysfs support (Linux 3.12+)
- Fixed some bugs
- Enabled debugging by default; you will now have to specifically
switch it off (./configure --disable-debug)
06/12/2013 - 0.5
----------------------
- Basic I2C support
- Add SPI header to include_header in configure.ac
06/10/2013 - 0.4
--------------
- Basic SPI support
- See lib/include/libsoc_spi.h
13/09/2013 - 0.3
--------------
- Non-blocking GPIO interrupts
/**
* \fn int libsoc_gpio_callback_interrupt(gpio* gpio, int (*callback_fn)(void*), void* arg)
* \brief takes a gpio and a callback function, when an interrupt occurs
* on the edge previously specified, the callback function is called
* \param gpio* gpio - the gpio for which you want the interrupt to
* trigger the callback function
* \param int (*callback_fn)(void*) - the function you wish to call with
* a void* pointer to a possible value you may wish to use in the callback.
* \param void* arg - pointer to data you wish to use in the callback function
* \return EXIT_SUCCESS or EXIT_FAILURE
*/
int libsoc_gpio_callback_interrupt(gpio* gpio, int (*callback_fn)(void*), void* arg);
/**
* \fn int libsoc_gpio_callback_interrupt_cancel(gpio* gpio)
* \brief cancel a callback on a gpio interrupt
* \param gpio* gpio - gpio with a valid callback enabled
* \return EXIT_SUCCESS or EXIT_FAILURE
*/
int libsoc_gpio_callback_interrupt_cancel(gpio* gpio);
- Added modes to gpio_request
gpio* libsoc_gpio_request(unsigned int gpio_id, int mode);
/**
* Valid Modes for libsoc_gpio_request
*
* LS_SHARED - if the gpio is already exported then it will not unexport
* the GPIO on free. If it is not exported, then it will
* unexport on free.
*
* LS_GREEDY - will succeed if the GPIO is already exported, but will
* always unexport the GPIO on free.
*
* LS_WEAK - will fail if GPIO is already exported, will always unexport
* on free.
*/
03/09/2013 - 0.2
--------------
- GPIO blocking interrupt support
/**
* \fn int libsoc_gpio_wait_interrupt(gpio* gpio, int timeout)
* \brief takes a gpio and waits for length of timeout or until an
* interrupt occurs. Will return EXIT_SUCCESS on interrupt or
* EXIT_FAILURE on error or timeout.
* \param gpio* gpio - the gpio for which you want to wait on interrupt
* \param int timeout - the max length of time to wait for interrupt in
* milliseconds
* \return EXIT_SUCCESS on interrupt caught, EXIT_FAILURE on error or
* interrupt missed
*/
int libsoc_gpio_wait_interrupt(gpio* gpio, int timeout);
- Improved error and debug handling
31/08/2013 - 0.1
--------------
- basic sysfs GPIO support
