## PY32 Ubuntu GCC 和Vscode开发环境搭建

今天和大家分享一下我这两天玩的py32f003，仅需6毛钱，提供HAL库和LL库，支持MDK和IAR开发

同时github上面也有gcc的模板程序，本次就介绍一下linux下基于gcc+pyocd的环境搭建

这个理论上其实是可以对接RT-Thread Nano的，这里先画一个饼，有空的时候可以试着对接一下🐶

#### 1. 安装 GNU Arm Embedded Toolchain

建议在实体机内下载后，传到虚拟机之中，再进行下面的解压等操作

```
sudo mkdir -p /opt/gcc-arm/
sudo tar xvf arm-gnu-toolchain-12.2.rel1-x86_64-arm-none-eabi.tar.xz -C /opt/gcc-arm/
cd /opt/gcc-arm/
sudo chown -R root:root arm-gnu-toolchain-12.2.rel1-x86_64-arm-none-eabi/
```

#### 2. 安装 PyOCD

官方建议从pip安装PyOCD，不要用自带apt仓库，不然版本太低，无法识别JLink OB

```
pip uninstall pyocd
/home/[user]/.local/bin/pyocd
/home/[user]/.local/bin/pyocd-gdbserver
/home/[user]/.local/lib/python3.10/site-packages/pyocd-0.34.2.dist-info/*
/home/[user]/.local/lib/python3.10/site-packages/pyocd/*
source ~/.profile
```

#### 3. 克隆py32的 template

```
git clone https://github.com/IOsetting/py32f0-template.git
```

#### 4. Edit Makefile

根据自己需要编辑Makefile

可以控制使用LL库，HAL库，FreeRTOS等

这里是针对py32f003x6型号，使用DAPLink烧录的。

```makefile
##### Project #####

PROJECT			?= app
# The path for generated files
BUILD_DIR		= Build

##### Options #####

# Use LL library instead of HAL, y:yes, n:no
USE_LL_LIB ?= n
# Enable printf float %f support, y:yes, n:no
ENABLE_PRINTF_FLOAT	?= n
# Build with FreeRTOS, y:yes, n:no
USE_FREERTOS	?= n
# Build with CMSIS DSP functions, y:yes, n:no
USE_DSP			?= n
# Build with Waveshare e-paper lib, y:yes, n:no
USE_EPAPER		?= n
# Programmer, jlink or pyocd
FLASH_PROGRM	?= pyocd

##### Toolchains #######

```

#### 5. 尝试编译，烧录

```
# clean source code
make clean
# build
make
# or make with verbose output
V=1 make
# flash
make flash
```

#### 6. Vscode配置

c_cpp_properties.json

这个要是没有写的话会报include出错，虽然编译烧录起来都没有问题，但是代码提示功能就基本没有了。

```json
{
    "configurations": [
        {
            "name": "Linux",
            "includePath": [
                "${workspaceFolder}/**",
                "${workspaceFolder}/User/**",
                "${workspaceFolder}/Libraries/CMSIS/Core",
                "/opt/gcc-arm/arm-gnu-toolchain-12.2.rel1-x86_64-arm-none-eabi/arm-none-eabi/include",
                "/opt/gcc-arm/arm-gnu-toolchain-12.2.rel1-x86_64-arm-none-eabi/lib/gcc/arm-none-eabi/12.2.1/include"
            ],
            "defines": [
                "PY32F003x6"
            ],

}
```

**识别不到DAPLink怎么办？**

实际发现有时候运行make flash，会一直在等待debug probe connect这时候可以试试拔插DAPLINK，重连一下，以及检查是不是连接到主机了而不是实体机中。
