WDS is a configuration generation tooldeveloped by Silicon Labs for its RF chips. With this tool, developers canquickly configure the chip, which greatly reduces development burden.Thisarticle applies to the following wireless chips:Si4362 .
2.the use guide
Install and open this software, thefollowing screen will be displayed:
In the figure, "Connect physicaldevice" is applicable to the situation where the user has a developmentboard, while "Simulate radio" does not require an actual device. Youonly need to select the corresponding chip model to configure. Fordemonstration purposes, select "Simulate radio". The followinginterface is shown in the figure:
In this interface, select the chip modeland version to be configured. Here, the author chooses the Si4463 C2 version theusually chooses as a demonstration. After selecting the main interface, enterthe following figure:
Here , choose which configuration mode to use. "RadioConfiguration Application" is to directly display the real value of thecorresponding parameter, suitable for general users; "Register Settingpanel" is to list the registers, and the user specifies the value of theregister. Suitable for experienced users; here we choose the former.
The above figure is the configurationinterface. It can be seen that the entire interface is divided into threeparts, namely project selection, configuration project, and deployment project.In general, the entire configuration process can be summarized as follows:
1. Select the type of project to beconfigured. The available options are Empty framework, Unmodulated work, etc.
2. Configure wireless parameters, includingfrequency and power, wireless related parameters, data packet parameters,interrupt and fast response registers.
3. Place the configured project everywherein the file, which can be a header file or a project file.
Each step is described in detail below
Project type. According to its name, youcan know the type it represents, which is selected according to the actualsituation.
Frequency and power. Set the basic power,rating and other parameters of the amplifier. The actual value of the settingmust be within the range supported by the chip.
RF parameters. Select the desiredmodulation method, data rate and other parameters.
Packet column. In actual communication,there may be multiple data packets, and the parameters used by each data packetare not necessarily the same. Here, each data packet can be configuredseparately. The configured parameters mainly include the length of the datapacket, whether CRC is enabled, whether Manchester encoding is enabled, whether4FSK is enabled, and so on. These parameters should be selected according tothe needs of the project.
Interrupt. Select according to the actualsituation.
3.Save the project file
You can choose to save the configuredparameters as a header file or as a Silabs IDE project file. Select accordingto the actual situation.
