1 Introduction:
Wireless Development Suite (WDS) is a Silicon Labs offers EZRadioPRO series configuration software and computer terminals for ISM band debugging. You can use this software module of the RF parameters, and configuration registers set interrupt pins.
2.SI4463 Overview
Silicon Labs SI4463 is a high-performance RF transceiver. Output power up to + 20dbm, the receiving sensitivity of -126dBm support, support for low-power, anti-jamming, has been widely used in various industries, with stable performance, transmission distance, penetrating ability and strong diffraction characteristics.
This paper describes how the corresponding parameters of the RF transceiver SI4463 by WDS.

FIG 3 is divided into three areas: 1, SelectProject selected area works, mainly comprising the left of the selected project template, where the template comprising a plurality of configuration works for the user to freely choose the right side is the operation area of the project, open and save into engineering projects; 2, configure project for the configuration of the project areas, mainly comprising the frequency, power, RF parameters, packet format, GPIO interrupts and other configurations; 3, DeployProject area of the export operation, mainly for deriving codes file or third-party projects. This process of configuring a radio frequency main work area is generally as follows:
3.Configure Project work area
Frequency and power options under three main configurations: Frequency, Crystal and Power amplifier (PA).

Frequency工作区域主要设置射频的载波频率，通道带宽和总的射频通道号。射频收发器的中心频率需要根据公式计算：中心频率=基本频率+通道带宽*通道号。
Crystal工作区域主要射频晶振的频率、晶振的容差和是否启用外部有源晶振，默认使用无源晶振，如需使用有源晶振，需要勾选“Use external TCXO/Ref Source”选项。
Power amplifier(PA)为功放配置区域，主要配置输出功率和PA的斜坡时间，如需使用外部PA斜坡控制，需要勾选”Enable ramp control of ExternalPA”选项，其中Ramping time在勾选”Enableramp control of External PA”后也需要配置。
3.1 RF parameters选项主要配置射频的相关参数
图 6
调制方式提供5种调制选项，分别为：OOK、FSK、2FSK、GFSK、2GFSK；空速、频偏、接收带宽和及控诉接收误码率需要按照需求进行相应的设置；RSSI threshold主要设置接收端通过判断RSSI来设置接收的阈值范围，当接收载波的RSSI大于此阈值时才与接收相应的数据包。
3.2Packet主要包含三个区域分别为：预定义模式选择区、域格式配置区和包格式配置区
图 7
预定义模式选择区包含多种软件自带的预定义数据包格式；
域格式配置区主要配置数据包中给的各种参数，其中，前导码使能、同步字使能、发送接收包长度、可变包使能、CRC配置、数据白化配置和曼彻斯特编码等参数都可通过勾选相应的方框使其使能或失能。
4.包格式配置区主要包含前导码、同步字和数据域的长度进行配置
1、Interrupts选项主要包含包处理中断，调制解调器中断和芯片中断。
2、GPIO and FRR选项主要用来配置射频芯片的GPIO0-GPIO3的引脚功能，可以通过配置这些引脚来产生数据包中断、调制解调器中断和芯片中断，方便使用引脚的方式查询射频的各种中断；也可以通过此区域配置SI4463芯片的4个快速寄存器的状态。
When fully configured parameters can be derived after the project area by exporting the configuration file parameters header files, for third-party software or development tools called.
This development guidelines aimed at SI4463 accordingly introduced, but also for all products SiliconLabs company EZRadioPRO series. Chengdu Electronic Science and Technology Co., Ltd. Bai billion special offers Silicon Labs' partial-chip solution SI4463, SI4438 and SI4432, can also provide special customized needs of our customers.
