e) Development environment

Here, taking the gpio-blink project as an example, we will briefly explain the development environment and compilation process. Please refer to the tutorial for detailed content:[1]3.1. Windows 下使用 CDK (类 MDK Keil)开发指南 — BL_MCU_SDK 开发指南 0.3 文档 (gitee.io)
Sword Pool CDK download link:[Xuantie]平头哥芯片开放社区-平头哥 (t-head.cn)
IDE: Download Sword Pool CDK, unzip and install
Routine: Decompress SDK bl mcu_ SDK release_ v1 .4.5.zip，
Move the decompressed folder to a fully English path (no Chinese in the path)
And find the cdk project file in the directory

Double clicking on the project file will create a complete project file in that directory Errors and warnings generated by CDK can be turned off

Double click again to open gpio-blink.cdkproj, and you can see the encoding in cdk

After editing the source code. Click the Rebuild Project key in the upper right corner to compile

After successful compilation, a bin file will be generated in the Obj folder for the next program download

f) Download instructions

Unzip burning tool/BouffaloLabDevCube-v1.8.3zip, run BLDevCube.exe program
As shown in the figure, find the corresponding tomI and dts files in the decompressed BouffaloLabDevCube-v1.8.3 folder
Select the compiled bin file in the Firmware column
Press and hold the Boot button on the board, and insert the USB cable. A new COM port will be generated in the device manager. Select the corresponding COM port.
Click Create&Down to create a new COM port, select the corresponding COM port, and click Create&Download to download the program. After successful download, a green 100% progress bar will be displayed as shown in the picture
