This need more analysis and experimenatation. * Will push this driver to the dev branch with the uart fixed to 0 * Both SC16IS750 (single uart) and SC16IS752 (dual uart, but only uart 0 is enable) * * myHall.cpp configuration syntax: * * I2CRailcom::create(1st vPin, vPins, I2C address); * * myAutomation configuration * HAL(I2CRailcom, 1st vPin, vPins, I2C address) * Parameters: * 1st vPin : First virtual pin that EX-Rail can control to play a sound, use PLAYSOUND command (alias of ANOUT) * vPins : Total number of virtual pins allocated (2 vPins are supported, one for each UART) * 1st vPin for UART 0, 2nd for UART 1 * I2C Address : I2C address of the serial controller, in 0x format */ #ifndef IO_I2CRailcom3_h #define IO_I2CRailcom3_h #include "Arduino.h" #include "IODevice.h" // Debug and diagnostic defines, enable too many will result in slowing the driver #define DIAG_I2CRailcom class I2CRailcom3 : public IODevice { private: byte cutoutCounter; public: // Constructor I2CRailcom3(VPIN firstVpin, int nPins, I2CAddress i2cAddress); static void create(VPIN firstVpin, int nPins, I2CAddress i2cAddress) ; void _begin() ; void _loop(unsigned long currentMicros) override ; void _display() override ; private: }; #endif // IO_I2CRailcom_h
