# Modbus LED driver
*Slave LED driver controlled by MODBUS RTU protocol*
### Hardware unit
MCU: Atmel AtMega8
XTAL: 14.7456 MHz
USART Baud Rate: 9600
Communication Parameters: 8 Data, 1 Stop, No Parity
Digital inputs: 2
PWM outputs: 4
Power supply: 12 VDC
Communication: RS485
ModbusID - address of unit
`void SetREG(unsigned int index, unsigned int val)` - change register value
`unsigned int GetREG(unsigned int index)` - return value of register
`SetREG(11, 0);` - set RED light intensity (PWM intensity)
`SetREG(12, 0);` - set GREEN light intensity (PWM intensity)
`SetREG(13, 0);` - set BLUE light intensity (PWM intensity)
`SetREG(14, 0);` - set WHITE light intensity (PWM intensity)
*Range 0 - 200*
Set the output (acceleration / deceleration of intensity change is included)
`SetRedDutyWish(GetREG(11));`
`SetGreenDutyWish(GetREG(12));`
`SetBlueDutyWish(GetREG(13));`
`SetWhiteDutyWish(GetREG(14));`
