Pin Assignment of Remote Control App

TWELITE / TWELITE DIP

The functions of pins used by the Remote Control App are represented using the names from the diagram of Extremely Simple! Standard App Pins.

Power Input

Connect a 3.3V (2.0-3.6V) power supply to VCC/GND.

Digital Input/Output

Child: 12 inputs 0 outputs / Parent: 12 outputs 0 inputs

Default input/output assignments.

Child: 8 inputs 4 outputs / Parent: 8 outputs 4 inputs

Input/output assignments when the option bit: 0x00001000 setting is enabled.

Child: 6 inputs 6 outputs / Parent: 6 outputs 6 inputs

Input/output assignments when the option bit: 0x00002000 setting is enabled.

Child: 0 inputs 12 outputs / Parent: 0 outputs 12 inputs

Input/output assignments when the option bit: 0x00003000 setting is enabled.

Serial Input/Output

TX/RX are used for transmission and reception of the remote control (UART).

Status LED Output

Used when outputting status during automatic application ID setting.

Make the LED light up when the output is Low (sink type).

Setting Input

Mode Setting Input

By leaving the Mx pins unconnected or connecting them to GND, you can switch between operating modes such as parent, child, and repeater.

Alternative Baud Rate Setting Input

By leaving the BPS pin unconnected or connecting it to GND, you can change the UART baud rate (communication speed) to a value other than 115200bps.

Channel Setting Input

Temporarily overrides the frequency channel.

Reset Input

By connecting a push button between RST and GND, you can implement a reset button. RST is internally pulled up.
