DMX Controller

The DMX Controller which is based on a gen4-uLCD sends DMX packets to vary the intensity of the bulb connected to the DMX slave. The slave is based on an ISP Dallas Microcontroller which is 8052 compatible.

How It Works

Components

• gen4-uLCD-35DT

• DMX Slave

• MOTG-RS485

• 3V regulator for MOTG-RS485 Module

• gen4-PA

• 30 way FFC Cable

• uSD Card

• Micro USB Cable

• Connecting Wires

Implementation

Step 1: Build

• Connect the modules as shown above. If you do not want to solder the 3.3V regulator, you can use  a small breadboard.

• Connect the display to your computer as shown in the image below.

Step 2: Program

• Download the project file here.

• You can download Workshop 4 IDE and the complete code for this project from our website.

• Open the project using Workshop 4. This project uses the ViSi Genie Environment.

• You can modify the properties of each widget.

Step 3: Compile

• Click on the Compile button.

     Note: This step could be skipped. However, compiling is essential for debugging purposes.

Step 4: Comp’n Load

• Connect the display to the PC using uUSB-PA5 and a mini USB cable. Make sure that you are connected to the right port. Red Button indicates that the device is not connected, Blue Button indicates that the device is connected to the right port.

• Now click on the “Comp’nLoad” button.

• Workshop 4 will prompt you to select a drive to copy the image files to a uSD Card. After selecting the correct drive, click OK.

Step 5: Mount uSD Card

• The module will prompt you to insert the uSD card.

• Properly unmount the uSD Card from the PC and insert it to the μSD Card slot of the display module. The image below must appear on your display after completing the steps above.

Demonstration

You can move the slider to change the value and see the intensity of the bulb connected to the DMX slave.
