然后调试到HAL_Delay()方法的内部发现 HAL_GetTick( )函数一直返回 __weak void HAL_Delay(uint32_t Delay) { uint32_t tickstart = HAL_GetTick(); uint32_t wait = Delay; /* Add a freq to guarantee minimum wait */ if (wait < HAL_MAX_DELAY) { wait += (uint32_t)(uwTickFreq); } ...
调试发现,程序卡在if ((HAL_GetTick() - tickstart) > HSE_TIMEOUT_VALUE)处,不往下进行。原因:重复使能时钟。
*/HAL_StatusTypeDefHAL_DMA_PollForTransfer(DMA_HandleTypeDef *hdma,uint32_tCompleteLevel,uint32_tTimeout){uint32_ttemp, tmp, tmp1, tmp2;uint32_ttickstart =0;/* Get the level transfer complete flag */if(CompleteLevel == HAL_DMA_FULL_TRANSFER) {/* Transfer Complete flag */temp = __...
为TIM1,那么,理论上是和APB2的FCKL2相关。...我们先定得找到延时函数所用到的参数配置,看源代码: 函数原型: __weak void HAL_Delay(__IO uint32_t Delay) { uint32_t tickstart...= HAL_GetTick(); while((HAL_GetTick() – tickstart) < Delay) { } } –> __weak uint32_t HAL_GetTick...
I have set up ThreadX on my STM32U5A9 board using CubeMX. In such configuration it is recommended to use SysTick for ThreadX and select some other
我正在尝试用stm32编写stm8代码。问题是我找不到一个SPI_Transmit函数,只有SPI_SendData。我需要这个函数通过SPI传输一个数组。stm32 SPI_transmit函数如下所示: /* Init tickstart for timeout management*& 浏览8提问于2022-11-30得票数 1 2回答 如何在stm32f303中生成时间戳? 、、 我正在编写代码,以生成...
