Development Board Accessories¶
The CI-F32XGT01D package contains the following accessories:
| Name | Purpose | Quantity | Included |
|---|---|---|---|
| CI-F32XGT01D | Development board | 1 | โ |
| Microphone | Sound pickup | 1 | โ |
| Speaker | Voice playback | 1 | โ |

Application Example¶
The CI-F32XGT01D development board kit is pre-flashed with factory firmware by default and can implement standard voice recognition and wake-up.
Connect the development board as shown below, turn on the power (the switch position near the USB port is ON), and you will hear the standard firmware voice prompts.
- Connect the TYPE-C USB cable to the USB interface labeled 4 in Figure 3.
- Connect the microphone to the microphone interface labeled 1 in Figure 3 (pay attention to microphone polarity: the red wire is positive, the black wire is negative; match the red wire to MIC+ and the black wire to MIC- according to the silkscreen).
- Connect the speaker to the speaker interface labeled 2 in Figure 3.
- Short the UART0 jumper at position 3 in Figure 3.
Note: The standard firmware on the development board uses a dual-microphone firmware. Therefore, both microphones need to be connected.¶
Command Words and Corresponding Playback for the Standard Development Board¶
Before shipment, the standard development board is programmed with standard firmware. When using it, you need to first say the wake word “Hello Jenny”. After you hear the response “I am here”, you can then say other command words. When you hear “Thank you for using” , you need to say “Hello Jenny” again to wake it up.
The table below shows the command words corresponding to one of our standard firmware versions:
Note: Some command words may be removed or added as needed without further notice.
| Command Word | Corresponding Playback | Command Word | Corresponding Playback |
|---|---|---|---|
| Hello Jenny | I am here | 30 Degree | OK, 30 Degree |
| Turn on AC | okay, Turn on AC | Turn on lights | okay, Turn on lights |
| Turn off AC | okay, Turn off AC | Turn off lights | okay, Turn off lights |
| Increase fan | okay, Increase fan | Max Brightness | okay, Max Brightness |

Firmware Programming¶
Connect the development board kit as shown in the application example. Follow the steps below to program the firmware and test it:
- Connect one end of the TYPE-C line to the USB port of the computer, and the other end to the USB port of the development board;
- Open the firmware programming tool (the tool can be found in the CI13LC_SDK\tools directory of the SDK development package, named PACK_UPDATE_TOOL.exe). Select the corresponding model based on the chip, click the firmware update button, select the firmware file that has been made, and find the serial port number allocated to the USB to serial debug tool on the computer. After preparation is complete, power cycle the board to enter programming mode, then you can download the firmware. If the USB-to-UART adapter is not recognized by the computer, please install the appropriate drivers.
- Turn on the power switch. When you see the LED light up on the development board, it indicates power is on and the firmware download will begin.
- After the firmware download is complete, power cycle the board. Upon startup, you will hear “Welcome to Smart Home Assistant, you can wake me up by saying ‘Hello Jenny’.” When you say “Hello Jenny,” the board will respond with “I am here,” indicating the standard firmware has been successfully installed and the development board is working properly.
- If you encounter any issues, please contact our technical support for assistance.
