Si446 usage record (II): generate header files using wds3

One 、 summary

Mentioned earlier , Use WDS3 Generate configuration , It's an important step . First post two Chinese links ：

1. WDS3 And SI4338 Use steps and configuration instructions
2. WirelessDevelopmentSuite Use guide

The introduction in the link is very detailed , The options of each interface are explained in Chinese .

This RF chip is used for the first time , Except frequency band 、 power , It is not clear what parameters need to be configured 、 What value should the parameter be set . So we still use the launch program demo, Go back to the parameters set and the values used . It's like using a QT An example of , To be familiar with API The library process , It's just much simpler now .

look WDS Tools can be configured according to their own , Generate code or header file , This article uses the method of generating header files . During program initialization si4463 When , Write the macro definition configuration in the header file directly si4463 in . This article briefly records the relevant contents .

Two 、 Generate header file

1. function WDS3-Setup-v3.2.11.exe, After installation, double-click to enter ：
2. choice Start simulation, Select the chip in the pop-up interface Si4463：
   
3. Select the first one for RF configuration . stay 《AN632: WDS User’s Guide》 Mentioned in , The second option is used with experienced users .
   
4. Don't modify it first , Use the default configuration to create a header file ：
   
   Select the storage directory .
   
5. Check the header file
   First look at the configuration generated by default
   
   Most of them are the same , There are not so many parameters that need to be modified .
   From the comments at the beginning , You can see most of the parameters that differ , go back to WDS Corresponding modification in

3、 ... and 、 Modify the configuration

3.1 Modify according to the notes

3.1.1 rate 、 bandwidth 、 frequency offset

Modify the data rate 、 frequency offset 、 Receive bandwidth

3.1.2 fundamental frequency

Set the fundamental frequency

3.1.3 To interrupt

Enable packet processing interrupt and modem interrupt

3.2 Specific instruction modification

3.2.1 RF_GPIO_PIN_CFG

GPIO0_PULL_CTL – 1 = Enable pullup.
GPIO0_MODE[5:0] – 32 = High while in the transmit state.

3.2.2 RF_GLOBAL_XO_TUNE2

3.2.3 RF_INT_CTL_ENABLE_3

3.2.4 RF_FRR_CTL_A_MODE_4

3.2.5 PKT_RX_THRESHOLD_12

3.2.6 RF_MODEM_RAW_CONTROL_10

2045 Can't find

3.2.7 RF_PA_MODE_4

3.3 custom payload

In the end, I didn't use , Ignore first
