[i=s] 本帖最后由 gogyyy 于 2025-2-6 18:19 编辑 [/i] 首先声明，个人接触单片机不久。现在情况是这样，使用的GD32F103c8t6，现象是：在现场程序不运行，简单来说就是重启电源也不运行，返回来后，检查电源什么的都正常，就是单片机不运行。 我使用的SW下载到单片机的程序，我这个时候把原来的程序重新下载到单片机后，竟然正常了，总共做了十来个，现在有两个这个情况的，不知道怎么回事。

[color=#1b1c21][backcolor=rgb(245, 247, 250)][font="][size=16px]单片机程序中使用的第三方库或模块之间可能存在函数名冲突了怎么办[/size][/font][/backcolor][/color]

程序死在了自带库的微秒延时 void BSP_SYSTEM_Delay_us(uint32_t usCnt) { /* SysTick default clock source: HCLK/8 = 32MHz/8 = 4MHz */ SysTick->LOAD = 4 * usCnt; /* Clear SysTick current counter value */ SysTick->VAL = 0; /* Enable SysTick counter */ SysTick->CTRL = SysTick_CTRL_ENABLE_Msk; /* Wait for SysTick counter to 0 */ while (!(SysTick->CTRL & SysTick_CTRL_COUNTFLAG_Msk))//死在这一部 { } /* Disable SysTick counter */ SysTick->CTRL = ~SysTick_CTRL_ENABLE_Msk; /* Clear SysTick current counter value */ SysTick->VAL = 0; }

单片机程序里可以直接将U盘里的文件主动拷贝到windows系统硬盘中吗？
