在IAR下,我想查看函数[mw_shl_code=applescript,true]/**
* @brief Returns the HCLK frequency
* @note Each time HCLK changes, this function must be called to update the
* right HCLK value. Otherwise, any configuration based on this function will be incorrect.
* @note The SystemCoreClock CMSIS variable is used to store System Clock Frequency.
* @retval HCLK frequency
*/
uint32_t HAL_RCC_GetHCLKFreq(void)
{
return SystemCoreClock;
}[/mw_shl_code]
但是编译器提示这句话没有作用 |
