Change Log
==========
v4.2.2
------
- Set explicit SPI frequency to allow board to work in newer kernels which has too high default frequency (PR#23)
v4.2.0
------
- Added daemon flag for PortEventListener.
v4.1.2
------
- Fixed bug with new Device Tree (Pi2) by changing GPIO_INTERRUPT_DEVICE
from `/sys/devices/virtual/gpio/` to `/sys/class/gpio/` and changing udev
rule.
v4.1.1
------
- Support varying listeners.
v4.1.0
------
- Added deregister to interrupts.
v4.0.1
------
- Fixed SPI file descriptor bug when closing.
- Fixed issue #14.
v4.0.0
------
- Ignored "Interrupted system call" error in `watch_port_events`.
- Rewrite main functions into chip specific (MCP23S17) class.
- GPIOInterruptDevice class replacing core GPIO enable/disable functions.
- SPIDevice class replacing spisend function. Can now add in spi_callback
function which is called before each SPI write.
- Updated installation instructions.
v3.1.1
------
- Added IODIR_FALLING_EDGE and IODIR_RISING_EDGE to replace IODIR_ON and
IODIR_OFF respectively. IODIR_ON and IODIR_OFF can still be used in the same
way as before. Falling/Rising Edge are for physical level 1/0, On/Off are for
logical (programmer) level 1/0.
Physical Level (pifacecommon.read_bit):
IODIR_FALLING_EDGE: 1 -> 0
IODIR_RISING_EDGE: 0 -> 1
Logical Level (pifacedigitalio.PiFaceDigital().input_pins[0].value):
IODIR_ON: 0 -> 1
IODIR_OFF: 1 -> 0
Remember that PiFace Digital Inputs are active low:
>>> pifacecommon.read_bit(0, INPUT_PORT)
>>> 1 # physical
>>> pifacedigitalio.PiFaceDigital().input_pins[0].value
>>> 0 # logical
- Fixed Debian package bug where setup script would not be executed.
v3.1.0
------
- Added debouncing with adjustable `settle time`.
v3.0.0
------
- Added timeout class (fixing Issue #2) in interrupts.
- Added support for interrupts on multiple boards.
- Interrupts must be enabled/disabled manually. Automatic handling of this
broke interrupts from multiple boards.
v2.0.2
------
- Moved version number to pifacecommon/version.py so that it can be read from
setup.py and bin/uninstall.py.
- Updated SPI help link to point to the new docs.
- Moved installation scripts into single file for Debian packaging.
v2.0.1
------
- Added version number in source.
- Added uninstall script.
v2.0.0
------
- Improved interrupts (different API, check the docs).
- Reduced scope of global variables from package to individual modules.
(Hiding namespaces from the end user is an attempt to simplify the interface
for children. However this package is not intended for that audience
and so messing with the namespaces only confuses things.)
v1.2.1
------
- Supports Python 2.
- Started using semantic versioning http://semver.org/.
v1.2
----
- Started using a change log!
- Removed errors submodule, custom exceptions now go in their respective
modules. This might change back in a future release.
- Fixed DigitalInput value bugs
- Fixed SPI transfer bug.. Function spisend now takes bytes as an argument
instead of a list. This makes more sense, since it returns bytes.
- Removed install.sh, everything is now handled by setup.py.
- Updated docs.
