小华单片机hc32f460系列cmake驱动

介绍

• 驱动来自小华的3.3.0版本,修改了部分代码,添加了部分功能.
• 支持配置为bootloader,app,normal三种模式.
• 还支持是否有rt-thread系统.
• bootloader模式下,flash前128KB为bootloader,其余为app.
• 添加了printf支持浮点打印.
• 当使用gcc-arm-none-eabi,11及以上版本的编译器时，编译时会出现LOAD segment with RWX permissions 警告,toolchain中可以忽略这个警告，但是忽略参数11版本以下的又不支持,所以保留了这个警告,修改链接脚本也可以消除此警告,但是同样不支持11版本以下的编译器,固没做修改.
• 使用严格的编程模式,任何警告都视为错误,停止编译,可以养成好编程习惯.

修改内容

• hc32_ll_can.c中const static uint8_t m_au8DLC2WordSize[16U]修改为static const uint8_t m_au8DLC2WordSize[16U] 将static放在最前面,以规范代码,去除警告.
• 当有rt-thread
  • 修改了startup_hc32f460.S中bl main修改为bl entry来支持rt-thread系统.
  • 修改了hc32f460xI.ld和hc32f460xG.ld链接脚本,来支持rt-thread系统相关自动初始化函数,来保证不被编译器优化.
  • 去除了usb驱动,需要其它文件,还没研究.

使用前准备

• Cmake下载
  • 安装Cmake,会自动将cmake安装到环境变量中,如果cmake提示未找到要手动将cmake的bin目录加入到环境变量中.
• MinGW下载
  • 安装MinGW编译器,如果是是解压类型,解压后把bin目录加入到环境变量中.
• gcc-arm-none-eabi下载
  • 安装gcc-arm-none-eabi,如果是解压型的,解压后把bin目录加入到环境变量中.
• pyOCD安装方法,这是下载和调试mcu的工具,只编译的话,不需要.
  • 还可以安装libusb,来显示更多调试信息,比如断言.

Cmake 配置例子

• 在自己的项目中添加本驱动

git submodule add https://github.com/nczyw/hc32f460-drivers.git drivers

• 项目CMake例子
