Drivers

The subsystem provides access and control of work of peripheral devices .

The subsystem includes the drivers for the following devices:
    1.  LCD;
    2.  Keyboards;
    3.  RTC on I2C;
    4.  RTC on TWI;
    5.  Internal EEPROM;
    6.  External EEPROM on I2C;;
    7.  External EEPROM on SPI;
    8.  FRAM on TWI;
    9.  FRAM on I2C;
   10. FRAM on SPI;
   11. Microcircuit DTMF;
   12. Modem;
   13. Power Line Modem;
   14. Power Line Microcircuits;
   15. MMC/SD on SPI;
   16. SLIDERS;
   17. PWM;
   18. ADExxxx Energy Metering.

Functions of drivers:
    - Parametrical tuning to the equipment;
    - Initialization of the served device;
    - Realization of the interface of access to the device;
    - Realization of the command system of the device;
    - Control of work of the device;
    - Interaction with system of input-output;
    - Processing interruptions;
    - And so forth.
