Application Example¶

The CI-D06GT01D development board kit comes with factory firmware pre-flashed by default, enabling standard voice recognition and wake-up.

Connect the development board as follows and turn on the power (switch near USB port is ON) to hear the standard firmware voice broadcast.

Connect the TYPE-C USB to the USB interface marked as 4 in Figure 3;
Connect two microphones to the analog microphone interface marked as 1 in Figure 3; (Note microphone positive and negative polarity, microphone red wire represents positive, black wire represents negative, connect red wire to MIC+ and black wire to MIC- according to the silkscreen);
Connect the speaker to the speaker interface marked as 2 in Figure 3;
Short the UART0 position marked as 3 in Figure 3.

Note: The default standard firmware of the development board applies dual microphones, so both microphones need to be connected in development.¶

Standard Development Board Command Words and Corresponding Voice Prompts¶

The standard development board comes with pre-installed standard firmware. To use it, first say the wake word “Hello Jenny”, after hearing the response “what can i do for you”, you can say other command words. When you hear “I am leaving, call me later”, please say “hello jenny” again to wake it up.

The following table lists the command words corresponding to our standard firmware.
Note: Check the stickers on the development board for the corresponding command words

Figure 9: Command Words for Standard Firmware

Firmware Flashing¶

After connecting the development board kit as described in the application example, follow these steps to flash and test:

Connect one end of the TYPE-C cable to the computer’s USB port and the other end to the development board’s USB port;
Open the firmware flashing tool PACK_UPDATE_TOOL.exe (this tool can be found in the SDK development package CI130X_SDK\tools directory), select the corresponding model according to the chip, click the firmware update button, select the prepared firmware file, and find the corresponding serial port number assigned by the computer to the USB to UART tool. After preparations are complete, enter programming mode by instant power-on of the chip, at which time the firmware can be downloaded. If the USB to UART tool cannot be recognized on the computer, please install the corresponding driver on the computer.

Figure 4 Firmware Flashing Tool Diagram

Turn on the power switch, when you see the light on the development board turn on, it indicates power is connected, and the firmware starts downloading.
Wait for the firmware download to complete, then power on again. After power on, you will hear “Welcome to use Smart fan, you can use hello jenny to wake me up”. At this time, when you say “hello jenny”, you will hear the development board broadcast “what can i do for you”, which means the standard firmware has been downloaded successfully and the development board is working normally;
If there are any abnormalities, please contact our technical staff for support.

Application Notes¶

For development board SDK debugging methods, users can refer to the document 《CI13XX Series Chip SDK》, which contains detailed usage instructions for how to do SDK debugging on this development board.
