于是再深入看一下HAL_GetTick()函数. 代码如下 __weak uint32_t HAL_GetTick(void) { return uwTick; } 1. 2. 3. 4. 也就是说, uwTick 不再更新了. 数值永远是某个固定数值. 那uwTick 到底是怎么更新的呢? 最后发现 在这里更新的. __weak void HAL_IncTick(void) { uwTick += uwTickFreq; ...

#include"rtx_os.h"externosRtxInfo_t osRtxInfo;uint32_tHAL_GetTick(void){return((uint32_t)osRtxInfo.kernel.tick); } This will avoid the fault. The code casts an internal uint64_t value as type uint32_t, and the value safely passes into the HAL layer. ...

1、串口的使用方法 在hal库中，有三个串口发送的函数 a、HAL_StatusTypeDef HAL_UART_Transmit_DMA(...
先掌握原理和设计再看代码会好一点，争取后面再写写细节和代码分析，一步一步来搞定它。
基本上，没有人会将大段的C语言代码全部塞入 main() 函数，更好的做法是按照复用率高，耦合性低的...
