Si446 usage record (I): basic data acquisition

One 、 summary

Use si4463 Realization 868M Band wireless communication . First contact si4463, I searched some experience on the Internet , There is still little information （ Or my search is wrong ）, And they are all aimed at the debugging process . It's still a little difficult to start with zero foundation , This article simply records the process of using .
I am based on a si4463 Launch program for debugging , So it saves a lot of process . Mainly to find relevant documents , To understand demo Realization of program function 、 Which parameters to modify .

Two 、 Data acquisition

The first is to obtain chip information . find datasheet It's very convenient , Direct Baidu si4463 Just a manual . But only datasheet It's not enough , I got it. datasheet And a demo Program , Registers used for parameter setting in the program , stay datasheet No relevant description can be found in . So we need to get more information from the official website （ Click to enter ）：

choice si4463( Fast jump )：

Here is SI4463 Summary of information , I started from FAE Find information at , This is the link given . Should say no , When I found it on the official website , Not found here , The retrieval ability is really a little poor ...
There are many official documents , According to the reading order , Recommend several important documents ：

1. DS_Si4463-61-60-C.pdf：datasheet
2. AN632: WDS User’s Guide for EZRadioPRO Devices
3. AN625: Si446x API Descriptions
4. AN633: Programming Guide for EZRadioPRO Si4x6x Devices

Later, according to the usage of the document , Record them separately .

3、 ... and 、DS_Si4463-61-60-C：datasheet

Like I said before , This datasheet Is the easiest to get , Baidu or the official website is very convenient .Si4463-61-60-C manual ： Click to see

stay datasheet Both sides mentioned , such as si4463 With the host MCU Hardware connection between 、API、WDS、 Command flow . Some descriptions are more detailed , Some just mentioned this noun many times , I only had one at first datesheet,demo Registers in the program , stay datasheet Only a few words can be found in , I'm confused .
At the beginning of contact , Look at the manual roughly , Just know there's such a thing .

Four 、AN632: WDS User’s Guide

WDS Full name the Wireless Development Suite (WDS), That is, the wireless development kit . It's like menuconfig, A graphical configuration tool .
FAE The advice is ： Go and have a look AN632. Use WDS Generating configuration is a very important step , You can also find Chinese documents 《WDS Software user guide ( Chinese mark ).pdf》.
The use of WDS The process of writing a separate article ：si446 Use records （ Two ）： Use WDS3 Generate header file .

5、 ... and 、AN633: Programming Guide

Click to quickly view ：AN633.pdf, Found a Chinese version ：si4463api-cn chinese , You can check .

5.1 CTS

si4463 During command processing , Unable to receive new instructions . So the mainframe MCU Before sending instructions , Need to ensure si4463 be in ready Put it on , stay 7.2 Section gives three methods ： Software rotation 、GPIO monitor 、IRQ interrupt . I use software polling ：

That is, after sending an instruction , Keep sending 0x44 Instructions , Until return 0xFF until . Ensure that the instruction execution is completed ,si4463 Get into ready state . stay 《DS_Si4463-61-60-C.pdf》 Mentioned in the CTS, The flow chart is given ：

6、 ... and 、AN625: Si446x API Descriptions

This document is in si4463 The page of data summary cannot be found , You can search directly on the official website AN625. The document has two parts: instructions and attributes . The attribute part is as a command 0x11-- Set properties Subset .
