Whetstone程序我用github被墙了所以用了KK的方式。 获取的程序目录如上所示。
2 新建STM32工程 配置如上生成工程即可。
3 在生成的工程中添加并修改Whetstone程序
3.1 实现串口打印功能
在生成的usart.c文件中添加些代码实现串口打印注意串口的IO引脚STM32G4的评估板需要外部连接串口USB口没有连接串口线。
#ifndef __MICROLIB
#define __FILE_INCOMPLETE 1
#endif
#include stdio.h#ifndef __MICROLIB
struct __FILE
{int handle;/* Whatever you require here. If the only file you are using is *//* standard output using printf() for debugging, no file handling *//* is required. */
}__stdout;
#endif
#define PUTCHAR_PROTOTYPE int fputc(int ch, FILE *f)// 该函数放在usart.c文件最后即可
PUTCHAR_PROTOTYPE
{/* e.g. write a character to the LPUART1 and Loop until the end of transmission */HAL_UART_Transmit(hlpuart1, (uint8_t *)ch, 1, 0xFFFF);return ch;
}此外需要在MX_LPUART1_UART_Init()函数中添加USART外设初始化函数。
HAL_UART_MspInit(hlpuart1);至此串口打印功能即添加完成。
3.2 修改whetstone.c
工程目录下新建Whetstone文件夹并将whetstone.c拷贝进去 给工程添加源文件

修改前 修改后
暂时没有具体分析细节问题只是跑通了
修改记录
2025.2.7——可能有朋友注意到了时间上是正好5s一般不可能这么规整检查了一下代码是time_in_secs()函数在转换时没有考虑到浮点导致。已修改
