## Development Guidelines
|

- MISRA-C 2012 compliance where practical
|
||||
- Consistent naming convention
|
||||
- Comprehensive error handling
|
||||
|
||||
2. **Real-Time Considerations**
|
||||
- Minimize ISR execution time
|
||||
- Avoid dynamic memory allocation
|
||||
- Use fixed-priority preemptive scheduling
|
||||
|
||||
3. **Testing Strategy**
|
||||
- Unit tests for algorithms
|
||||
- Integration tests for protocols
|
||||
- System tests with reference clocks
|
||||
|
||||
4. **Documentation**
|
||||
- Doxygen comments for APIs
|
||||
- Design documents for complex modules
|
||||
- User manual for configuration

|
||||
由于我们的LCD越来越多，不便于我们的维护，因此把所有的LCD程序做成一个工程。
|
||||
在这里简略的描述本工程的使用：
|
||||
|
||||
1.基本信息：
|
||||
本例程用于测试或者演示RP2040-ETH上WS2812B;
|
||||
|
||||
2.管脚连接：
|
||||
DIN -> 25
|
||||
|
||||
3.基本使用：
|
||||
你需要执行：
|
||||
如果目录已经存在，则可以直接进入。 如果没有目录，执行:
|
||||
mkdir build
|
||||
进入目录，并添加SDK:
|
||||
cd build
|
||||
export PICO_SDK_PATH=../../pico-sdk
|
||||
其中 ../../pico-sdk 是你的SDK的目录。
|
||||
执行cmake，自动生成Makefile文件:
|
||||
cmake ..
|
||||
执行make生成可执行文件，然后在终端中输入：
|
||||
make
|
||||
编译好的uf2文件复制到pico中即可

This file is to help you use this routine.
|
||||
Since our ink screens are getting more and more, it is not convenient for our maintenance, so all the ink screen programs are made into one project.
|
||||
A brief description of the use of this project is here:
|
||||
|
||||
1. Basic information:
|
||||
This routine is used to test or demonstrate WS2812B on RP2040-ETH.
|
||||
|
||||
2. Pin connection:
|
||||
Pin connection You can look at dev_config.c/h in \lib\Config. Again, here:
|
||||
DIN -> 25
|
||||
|
||||
3. Basic use:
|
||||
You need to execute:
|
||||
If the directory already exists, you can go directly. If there is no build directory, execute
|
||||
mkdir build
|
||||
Enter the build directory and type in the terminal:
|
||||
cd build
|
||||
export PICO_SDK_PATH=../../pico-sdk
|
||||
Where ../../pico-sdk is your installed SDK directory
|
||||
Execute cmake, automatically generate Makefile file, enter in the terminal:
|
||||
cmake ..
|
||||
Execute make to generate an executable file, and enter in the terminal:
|
||||
make
|
||||
Copy the compiled uf2 file to pico
