BeagleBoneBlack-GPIO

Simple C++ library that handles GPIO calls for BeagleBone Black

Features and methods

1. Easy operations on gpio names:

• GPIOConst::getGpioByKey - i.e "P8_10"
• GPIOConst::getGpioByName - i.e "GPIO0_7"
• GPIOConst::getGpioNameByPin - i.e "12"
• GPIOConst::getGpioKeyByPin - i.e "12"
• GPIOConst::isPinAllocatedByDefault - refering to https://github.com/derekmolloy/boneDeviceTree/tree/master/docs

2. Easy operations on gpio sysfs descriptors:

• GPIOManager::exportPin - Export pin (equivalent to i.e echo "68" > /sys/class/gpio/export)
• GPIOManager::unexportPin - Unexport pin (equivalent to i.e echo "68" > /sys/class/gpio/unexport)
• GPIOManager::setDirection - Set direction (equivalent to i.e echo "in" > /sys/class/gpio/gpio68/direction)
• GPIOManager::getDirection - Get direction (equivalent to i.e cat /sys/class/gpio/gpio68/direction)
• GPIOManager::setValue - Set value (equivalent to i.e echo "1" > /sys/class/gpio/gpio68/value)
• GPIOManager::getValue - Get value (equivalent to i.e cat /sys/class/gpio/gpio68/value)
• GPIOManager::setEdge - Set edge (equivalent to i.e echo "rising" > /sys/class/gpio/gpio68/edge)
• GPIOManager::getEdge - Get edge (equivalent to i.e cat /sys/class/gpio/gpio68/edge)
• GPIOManager::waitForEdge - Wait for edge event
• GPIOManager::countExportedPins - Count already exported pins
• GPIOManager::clean - Unexport all of already exported pins

3. Export/unexport sanity check
4. Table with pins being exported by default
