It sounds to me that your codebase may have an override for that function. See this post about HAL_GetTick (): STM32 and HAL function GetTick () As an alternative you can do the following. If you know the frequency of a timer you can use the following code snippet: const uint32_t freq = 1000000; // Freq in Hz uint32_t get_ticks () { uint32_t ...

WebApr 1, 2024 · An alternative method is to count the edges over a period of time, determine the frequency by count/time where the longer the time period, the more precise the measurement. You could even have a fixed minimal precision by requiring a minimum number of counts. For example 1000 counts will give 0.1% precision.

Web# 前言-----我们使用STM32CUBEMX软件生成的工程里，有一个官方提供的延时函数HAL_Delay(uint32_t Delay)，这个函数提供一个1ms的延时，并且不占用系统，因为这是一个利用滴答时钟实现的。但是在我们实际使用中，1ms的延时真是太久了，有些外设还真的是需要使用到us级别的延时，那怎么办！
