[untested] added Sk6822 led device support (#397) * Adding support for sk6822 timing This isnt complete, but should be a good starting point for others to learn from. 1) Here is where the led device source is located: cd libsrc/leddevice 2) Find the files that need changing: root@loungepi:libsrc/leddevice# grep -ri 2812spi * CMakeLists.txt: ${CURRENT_SOURCE_DIR}/LedDeviceWs2812SPI.h CMakeLists.txt: ${CURRENT_SOURCE_DIR}/LedDeviceWs2812SPI.cpp LedDeviceFactory.cpp: #include "LedDeviceWs2812SPI.h" LedDeviceFactory.cpp: REGISTER(Ws2812SPI); LedDeviceSchemas.qrc: <file alias="schema-ws2812spi">schemas/schema-ws2812spi.json</file> LedDeviceWs2812SPI.cpp:#include "LedDeviceWs2812SPI.h" LedDeviceWs2812SPI.cpp:LedDeviceWs2812SPI::LedDeviceWs2812SPI(const QJsonObject &deviceConfig) LedDeviceWs2812SPI.cpp:LedDevice* LedDeviceWs2812SPI::construct(const QJsonObject &deviceConfig) LedDeviceWs2812SPI.cpp: return new LedDeviceWs2812SPI(deviceConfig); LedDeviceWs2812SPI.cpp:bool LedDeviceWs2812SPI::init(const QJsonObject &deviceConfig) LedDeviceWs2812SPI.cpp:int LedDeviceWs2812SPI::write(const std::vector<ColorRgb> &ledValues) LedDeviceWs2812SPI.h:class LedDeviceWs2812SPI : public ProviderSpi LedDeviceWs2812SPI.h: LedDeviceWs2812SPI(const QJsonObject &deviceConfig); 3) Copy the existing files as a starting point: cp LedDeviceWs2812SPI.cpp LedDeviceSk6822SPI.cpp cp LedDeviceWs2812SPI.h LedDeviceSk6822SPI.h cp schemas/schema-ws2812spi.json schemas/schema-sk6822spi.json 4) Do some search and replacing: :%s/Ws2812SPI/Sk6822SPI/g 5) edit the other files (see the diffs in this commit) * Added wait time and reset time * Fixed up debugging output and commented it out.
