Welcome to AI Voice Interaction Module repository

For RDK X5

RDKX5 serial communication

Note: The voice interaction module needs to be burned with factory firmware. If the voice chip has not been flashed with firmware after receiving it, it does not need to be burned

1. Experimental preparation

RDK X5
Voice interaction module
Type-C data cable

2. Wiring diagram

Use type-c wiring to connect to the motherboard

Slide the module to the right, use the serial port of the stc firmware,

Input in the terminal, the ttyUSB0 device appears, indicating that it has been recognized normally (normally it is ttyUSB0, and it may also be other device numbers)


ls /dev/ttyUSB*

3.Achievement effect

You can select the broadcast content by modifying the code in the program as shown below

The broadcast content can be viewed according to the Command Word Broadcast Word Protocol List V3_EN file provided in the attachment.

The first and second bytes AA FF represent the frame header of the protocol, the third byte FF represents the broadcast function, and the fourth is the ID of the broadcast content. Here you can see "I am ready" is hexadecimal 67, so the program sends 0x67 to register 0x03 to broadcast the corresponding content. The fifth byte is the end frame.

Enter the following command in the terminal to run the program. When you hear I am ready, it means the program is running


xxxxxxxxxx
python3 uart_test.py

After I say the wake-up word to wake up, I say "Close light" and the debugging assistant will reply to receive 10

At this time, you can open the attached Command Word Broadcast Word Protocol List V3_EN file to view the "Turn off the light" protocol

The first and second bytes AA FF represent the frame header of the protocol, the third byte represents the ID of the ten function words of the chip, and the fourth is the command word ID. Here you can see "Close light" is hexadecimal 0A, decimal 10. The fifth byte is the end frame.

Say other command words, the serial port debugging assistant will also print the corresponding command word ID, you can try it yourself
