3. Functional Description
3.1Interface Description
Table 3-1. Interface Description for Lamp configure
Interface Pin Function Description
PWM
PWM – CW
PWM – WW
PWM – R / G / B
Currently the PWM interface has five channels.
PWM interface can realize the control of LED lights directly.
PWM
PWM – DIM
PWM - CCT
The DIM & CCT are PWM signal. The DIM control the dimming ratio
and CCT control the CW / WW ratio for the LED lamp.
PWM
PWM – DW The PWM signal for dimmable white lamp.
I2C
SDA
SCL
The I2C (master) signal for dimming control of RGB LED. The LED
driver should be an I2C slave to
ADC
ADC
Tests the input voltage of the ADC pin.
UART
UART_Rx
UART_Tx
Communicates with the UART device.
Table 3-2. Interface Description for Plug configure
Interface Pin name Function Description
Digital Output
Wifi status An IO to indicate the Wifi activity. When Wifi is active, this pin will pull
low to sink a current. The sink is 20mA max.
Digital Output
Relay status An IO to indicate the Relay status. When Relay is on, this pin will pull
low to sink a current. The sink is 20mA max.
Digital Output
Relay drive An output signal to control the Relay. An output high to control the
relay on. An output low to control the relay off.
Digital Input
Button Connect to the press button for control. The press button is required
to connect between this IO and Ground. A pull high resistor of
normally 10K is required to connect to this IO to function properly.
ADC
ADC
Tests the input voltage of the ADC pin.
UART
UART_Rx
UART_Tx
Communicates with the UART device.
