Application of the E180-Z5812SP Module in Wireless Dimming
Hardware Connection
The E180-Z5812SP module is connected to the dimming device through the serial port to control the light brightness. The specific connection methods are as follows:
Power connection: The module is powered by a 3.3V DC power supply.
Serial port connection: The TXD and RXD pins of the module are connected to the RXD and TXD pins of the dimming device respectively.
GPIO connection: The GPIO pins of the module are used to control the switch and brightness adjustment of the dimming device.
Software Configuration
Configure the coordinator: First, configure an E180-Z5812SP module as a coordinator, open the network, and set the network parameters.
Configure the terminal nodes: Configure other E180-Z5812SP modules as terminal nodes and let them join the network where the coordinator is located.
Set dimming parameters: Set the dimming parameters of the terminal nodes, including brightness level and dimming speed, through serial port commands.
Implement dimming control: The terminal nodes control the brightness of the dimming device through the GPIO pins according to the received dimming instructions.
Realization of 0 - 100% Stepless Brightness Adjustment
The stepless brightness adjustment from 0 to 100% can be achieved through the serial port commands of the E180-Z5812SP module. The specific steps are as follows:
Send dimming instructions: Send dimming instructions, including the target brightness and dimming speed, from the host computer software to the coordinator.
Coordinator forwards the instructions: After receiving the dimming instructions, the coordinator forwards them to the corresponding terminal nodes.
Terminal nodes execute dimming: After receiving the dimming instructions, the terminal nodes control the brightness of the dimming device through the GPIO pins to achieve stepless adjustment from 0 to 100%.
