Customization via Interactive Mode

What is Interactive Mode

Interactive Mode is a mode used when connecting the TWELITE series to a PC for configuration. By connecting the TWELITE series to a PC via a USB adapter TWELITE R series, you can change various parameters through UART communication.

Custom Examples

Below are customization examples of TWELITE DIP for different purposes.

Please select and try the ones you are interested in.

• Network Grouping
  • Prepare two pairs of parent and child devices and operate them independently
• Using Low Latency Mode
  • Prepare a pair of parent and child devices and reduce delay in transmission from DIx to DOx
• Transmit Only When Button is Pressed
  • Prepare a pair of parent and child devices and configure so that transmission occurs only when the parent’s button is pressed

Network Grouping

By default, all TWELITE DIP devices can communicate with each other. When you prepare two pairs of parent and child devices, the inputs of the parent are reflected to both children, and the inputs of the children are reflected to both parents.

Using Interactive Mode, change the Application ID and frequency channel to separate the two pairs so they can be used independently at the same time.

Products Used

Extremely Simple! Standard App	-
4 units	1 unit

Customization Details

Set the Interactive Mode values as follows to divide the two pairs into Group A and Group B.

• Group A
  • Parent / Child
    • Application ID: 0xAAAAAAAA
    • Frequency Channel: 11
• Group B
  • Parent / Child
    • Application ID: 0xBBBBBBBB
    • Frequency Channel: 26

Customization Procedure

1. Insert the TWELITE DIP into the TWELITE R2 and connect it to the PC using a USB-C cable
2. Launch the TWELITE STAGE app and select the target TWELITE R2 from Serial Port Selection
3. From the Main Menu, select “3: Interactive Mode”
4. Press uppercase R to reset settings to default
5. Press a, input AAAAAAAA / BBBBBBBB, and press Enter
6. Press c, input 11 / 26, and press Enter
7. Press uppercase S to apply settings (TWELITE will reset)
8. Press ESC several times to return to the Main Menu and disconnect the TWELITE R2 USB-C cable
9. Remove the TWELITE DIP and insert it into a breadboard or connect it to the circuit

Operation Check

Wire both Group A and Group B as in the “Try It Out First” One-Way Digital Signal Example, connecting a switch to the parent and an LED to the child.

• Pressing the switch on Group A’s parent lights only Group A’s child LED
• Pressing the switch on Group B’s parent lights only Group B’s child LED

Change the Application ID of Group B’s child to 0xAAAAAAAA and the frequency channel to 11.

• Pressing the switch on Group A’s parent lights LEDs on both children

Using Low Latency Mode

By default, there is a delay of about 30-70ms from when the source DIx changes until it is reflected on the destination DOx. This delay exists due to processing to avoid chattering and wireless packet interference.

Low Latency Mode shortens this delay to about 3-10ms by simplifying these processes.

Enable low latency mode on the transmitting device (parent) via Interactive Mode.

Customization Details

Set the Interactive Mode values as follows to enable low latency mode on the transmitting device (parent).

• Parent
  • Option Bits: 0x00000001
• Child: No change

Customization Procedure

1. Insert the TWELITE DIP into the TWELITE R2 and connect it to the PC using a USB-C cable
2. Launch the TWELITE STAGE app and select the target TWELITE R2 from Serial Port Selection
3. From the Main Menu, select “3: Interactive Mode”
4. Press uppercase R to reset settings to default
5. Press o, input 00000001, and press Enter
6. Press uppercase S to apply settings (TWELITE will reset)
7. Press ESC several times to return to the Main Menu and disconnect the TWELITE R2 USB-C cable
8. Remove the TWELITE DIP and insert it into a breadboard or connect it to the circuit

Operation Check

Wire the parent and child as in the “Try It Out First” One-Way Digital Signal Example, connecting a switch to the parent and an LED to the child.

• Pressing the parent’s switch lights the child’s LED
• The operation is the same as the default state, but you might notice slightly improved response
• Connect an oscilloscope to the parent’s DO1 and child’s DI1 to compare and confirm the effect

Transmit Only When Button is Pressed

By default, transmission occurs when the input state changes and also once every second.

In this case, for example, if the transmitting device’s button is held down and the power is cut, the output on the receiving side remains.

The Transmit Only When Button is Pressed setting causes the transmitting device to repeatedly send when DIx is Low, and continue sending for one second after transitioning to High. If the receiving device’s DOx is set Low and reception stops, it returns to High.

Change the setting via Interactive Mode to transmit only when the button is pressed.
