TIMEOUT_VALUE的值是否合适。如果超时值设置得太小，可能会导致程序在启动时等待外部时钟的过程中卡死。
发现我使用库里的延时程序HAL_Delay()时,会卡死在里面。 根据程序,进入到这个延时程序后 ,发现HAL_GetTick()取来的数字一直没有变化,才发现是因为 1 2 3 4 __weak uint32_t HAL_GetTick(void) { returnuwTick; } 程序中的值没有变化,搜uwTick后发现,其值由另一个程序进行处理, __weakvoidHAL_IncTick...

STM32之HAL库串口USART丢数据及ORE卡死的解决方案 刚装了VS2019Preview,VS2017系列应该还有最后一章就结束了,找个时间结束掉它。 昨晚弄了下STM32的串口通信,发现UART在接收PC串口调试助手发送的数据的时候,会时不时卡死,不能接收新的数据。之前公司有人做这方面的项目的时候也是这个情况,当时发现UART处于ORE(overru...
