The CB5654 intelligent voice development board is an application development board based on the SC5654 chip and provides a wealth of peripheral resources. Developers can quickly design products such as storytelling machines and smart speakers based on this development board. The white outer packaging of this product is very simple, as shown in Figure 1.
Figure 1 Outer packaging
Open the outer package, and you will find that the interior is mainly composed of a development board and corresponding accessories, namely the CB5654 development board, a speaker, an IPEX antenna, a 5V power adapter, and two Micro USB cables, as shown in Figures 2 and 3.

So how does the development board arrange its resources?
As shown in Figure 4, it consists of the following parts:
Power interface
This interface is used to connect an external 5V adapter to power the development board.
l Emulator interface
That is the JTAG interface, which is used for simulation debugging. The corresponding driver must be installed on the computer before use.
Information interface
That is the serial port, which is used for information transmission. The USB driver of CP2102 needs to be installed on the computer before use.
l Antenna interface
Use this interface to connect an external PFC antenna. It should be placed perpendicular to the ground plane during use, so that the WIFI signal transmission effect is best.
l SD card interface
This interface is used to place the SD card to store information and data in the form of files.
l Expansion interface
The expansion port uses a 2.54mm pin header, and can be connected to an external module for debugging using a DuPont cable.
l Speaker interface
This interface is used to connect an external speaker so that listening can be performed within a certain range.
Headphone jack
This port is used to connect headphones and is only for personal listening so as not to disturb others.

As an expansion interface, its pin assignment is shown in Table 1.

At this point, if you are impatient, you can connect the speaker to the development board, and then connect the power adapter. You will hear a voice prompt of "starting", and there will be no other movement.

The working mode of the development board is shown in Figure 6, so the corresponding driver installation is essential.

To drive the serial port, you need to install the corresponding driver. Since the WIN7 operating system is used, the installed driver is CP210x_Windows7_Drivers.exe.
To drive the debugging interface, you need to install Debug Server. Since you choose to develop under WIN7, the installed driver is CSKY-DebugServer-windows-V5.10.13-20210416-2100.exe.
After completing the driver installation, complete the connection as shown in Figure 7, and you can see the result shown in Figure 8 in the device manager.

At this time, if you open CSKYDebugServer, it will be shown in Figure 9.

Since the serial port number is too large, it will fail to open if used directly, so you need to reduce the serial port number.
After setting the serial port parameters, you will see the contents shown in Figures 10 and 11 when you open the serial port.
Unfortunately, it seems that the WIFI is not connected, so there is no voice interaction function.
The next task is to connect WIFI to test voice interaction and build its development environment.
